    DRZ Motor Need Advice

    Hey guys, Looking for some information and advice. Have a 2006 DRZ400S with 10,600km on it. Just picked it up. It had been sitting since sometime in the fall, maybe September. It started and ran for a couple minutes. Run down of what I've done: took the carb out and apart, wanted to give it a clean. Found the O-rings on the float needle seat, and the main jet holder were deteriorated. The rest of the carb seemed ok. Checked the oil dip stick, smelled like gas. Makes sense, carb must have been leaking gas into the motor. When I removed the carb, there was a puddle of gas in the engine intake. I went to check the valves, got the valve cover off, then went to take off the caps so rotate the engine and line up the timing marks, and as soon as I started unscrewing it oil, or more like gas, started coming out. Got the oil pan under it, and cracked the case oil drain bolt... a mixture of gas and oil poured out, A LOT came out... I don't know how much volume is available in the engine, but the amount of gas/oil that came out filled the entire oil catch pan, must have been 4 or more litres. Not good... I rotated the crank and lined up the timing marks, the cam lobes seemed to be in the correct location, the lines all made sense I think. I checked the valves: EX= 0.23mm-0.25mm IN=0.15mm I was able to rotate the engine with the spark plug still in... should I be able to rotate the crank with the spark plug still in? Does the auto decomp allow this, or is there an issue there? The engine rotates, it isn't stuck or anything, however it seems that it gets a little stiff at the top of the stroke, and at some point makes a click. Here is what I can see so far: The cams appear to be in good condition to my untrained eye, thoughts? Appears to be properly timed, 15 pins between teeth, little confused by the numbers on the cams, no idea what they mean. Also I'm assuming these are the stock cams, I don't think any work was done on this motor. Looking down the intake at the intake valves. I also stuck my scope down the spark plug hole, but it was too big to get into the cylinder to see anything meaningful. So, what to do next... do the cams look ok? What would the gas in the motor have possibly damaged or done? Could it have hydro locked the motor and blown something (hence turning over even with the plug on)? Best way to flush the system of the gas? Should I pull the head? I'm thinking yes just so I know whats going on in there... this would be the first real motor work I've done. Just wanted to get some opinions. Thanks in advance!

    2017/2018 KTM 250/300 gas tank

    As I get my 2017 300xcw jetting sorted out I got my first estimate on fuel mileage. At a B pace in the woods I'm getting roughly 30 to 35 mpg. With the stock 2.5gal tank that should be good for about 75 miles. This is somewhat limiting in range. I am considering a IMS 3.2 gal (~95+ mile range) and Acerbis 3.0 gal (~90+ mile range) Who has put one of these tanks on their 2017 or 2018 smoker? How was fit and ergonomics?
  4. Just bought a Husqvarna TX300 and the stock mikuni is giving me the worst gas mileage I have ever experienced on any 2 stroke. There is a little bit of spooge but not enough to seem extremely rich. Also, when I began running out of gas I would shut the gas off and the remaining gas in the bowl seemed to go forever. Perhaps the float if too high?

    Sunoco 110

    Not that many things on here regarding fuel and the Yz125 specifically. Locally, I can only get 91 octane ethanol gas, which is not what the manual calls for. It calls for 93 or higher......I have two other options each about 20 miles away....one is 93 octane ethanol gas from the pump, or go to sunoco and get 110 octane ethanol free......Any thoughts? Keep in mind, my engine is stock, and I don't plan to mod it out a whole lot in the near future. Any harm to running the 110 gas?
  6. The first year I owned my 250L, I gooned around in supermoto trim 100% of the time. If I wanted to ride off-road I would trailer my dirt bike since there are no extensive public trails within 1 hour of my home. 6 months ago I wore out my street supermoto tires again. Got busy, never ordered replacements so I swapped over to the stock wheels and tires. I started venturing further out to do more off-road. This eventually led to rim locks, better tires, skid plate, full RaceTech suspension and some supplemental luggage. The luggage I've been carrying is basic. Wolfman enduro tank bag, Wolfman fender bag, Wolfman bottle holder with 1L of extra fuel. I also ride with an off brand CamelBak. I carry basic tools, 1 spare tube and 2 spoons, phone, charger, air pressure guage, bike pump, zip ties, GoPro stuff. I'm getting bored of the local riding area and I want to start taking full day trips. I ride alone most of the time, I probably prefer it even. My questions: What is your must have gear for day trips that might also fit in my current bare bones luggage? I don't want more bags. I don't have rain gear except for my tank bag. I figure if it's calling for rain I'm not going and if it rains late in the day, I'm headed home. Bad idea? Do any of you trailer your bike to get closer to the action? Most of the riding I want to do is in the mountains of NC. I'm about 1.5-2 hours east of the roads I'm trying to get to. That's an extra 3+ hours of riding to get to the good spots and get home! What do you use for GPS? I use google maps on my phone typically. However I don't expect to have service in some locations. Does anyone use a device like the Garmin InReach? My wife would prefer I get one of those since I ride alone and will be on remote forest roads. Thanks for the advice.

    TTR90 limiter problem

    So I bought a ttr90 and it seemed to have some sort of limiter at full throttle so me and my friends took apart the carb and has it jet cleaned and bought a rebuild kit, came with the jets and everything. After replacing everything it seemed to run the same. So we did valve clearance and timing and put those in spec but still having a issue with the limiter also it doesn't idle now. If you take off the intake you can see that gas is shooting out the carb into the intake tube and we can't figure it out. Any ideas you guys can think of that we haven't tried?

    Oil smells faintly like gas

    I bought my DRZ new in April and have since accumulated 1,000 miles and use it to commute to work (I live 5 city miles away). I was starting to remove the air filter to begin the 3x3 mod and the filter was sticky and smelt like gas. I did some digging around the forum and found out there could be two reasons for this. The petcock is leaky or I left my carb on Prime for some time and the gas flowed backwards. I'm pretty sure it's the second one as I remember one occasion where I left it on Prime for a few hours (my first carbureted anything). I currently have a cup under the petcock and will see if anything leaks out of it, but I am doubtful that is the problem. So I'm looking for some advice on what to do now. I've changed the oil twice already, so it's only been 500 miles or so since the last change, so any gas in the oil is since then. And the oil just faintly smells like gas. It took a few attempts to smell anything like gas. Should I just change the oil, call it good, not do the 3x3 rejet and use the warranty if needed? Or could this be something much bigger and I should go back to the dealer?
  9. Hey guys, Newbie in town here. I recently got a 2003 xr400 and love it! have only ridden it up and down the street so far because of one problem. the second I turn the gas switch on the carb over flow tubes spew gas. it will run great with no gas dripping but the second I stop and idle (and turn off the bike) the tubes just spew gas out. carb has recently been cleaned. any suggestions/ tips would be great. ive done a ton of research but just havent busted this problem yet. Thanks! Ryan
  10. My rm125 leaks gas when sitting there on the stand with gas off. I've tried cleaning carb to make sure no dirt or anything! Please help! Also my kickstarter is tight when pulling out?
  11. Whaddup boys and girls, New around here, as well as very new to the dirt biking (riding in general) scene. I recently moved out of the city and more, country livin' so I got a dirt bike. I got a '04 YZ250F and haven't had much problems with it, except as I've been getting more and more comfortable on the throttle, and practicing my wheelies and such, I noticed... Low RPMs (Just above standstill, probably below like 10-20km/h) When i crack the throttle, it bogs if I'm going very slow/at a stand still. I have to release the throttle and twist the throttle more slowly (up to about 20km/h) then I can crack her wide open no problem. My question is, because I bought a racing bike, is it intented to be like this, since they would require a lot less low end power (since they're starting in dirt/mud/sand etc) or is there an issue with my bike. If there is an issue, what would possibly be the fix? Since i've had my bike (About 2-3weeks now) I've done: -oil change, air filter change, oil filter change, installed new sparkplugs and personal stuff such as suspension stiffness, handlebar position. Anything else I should be doing often other than those ^ (above) and is there a fix to my bike issue? or this how it is suppose to be? Thanks in advance homies.

    gas tanks

    I ride a 2005 Kawasaki KDX200 and I about ran out of gas on a ride today at a national forest and was wondering if anyone knew if there was a bigger gas tank than the ClarkeMFG 3.6 gallon tank for my bike.

    Replacement Gas Cap?

    Hello everyone, I am trying to find a cheap replacement for the stock DRZ400sm gas cap. Zeta has one but it requires the inners from the original. I bought another gas tank to use for the woods but it didnt come with a gas cap. Looking for something inexpensive that i wont have to use the inners from my other cap for. I just cant bring myself to spend the 100+ on one off of ebay. I dont care if it locks or not either? Any ideas????
  14. So i have a 2016 FC250 with the acerbis oversize tank, and it feels very wide. A friend with the exact same bike, only with an IMS tank rode mine and commented on its wideness as well. Anyone know the width of the IMS tank for this bike, so i have something to physically compare mine to? Thank you!

    Help! RM125 leaking gas!

    So my friend bought an rm125 with a blown top end, so we replaced everything, got it all put back together and the bike wouldn't start. We are getting strong spark, but that doesn't seem to change anything. The carburetor was leaking a steady stream of fuel from the overflow when the petcock was opened, so I assumed since it was sitting for so long, probably just a stuck or blocked needle valve. Pulled the carburetor apart, cleaned it and put it back together. Same issue persisted. Eventually bought a new carburetor, installed it, and after a few kicks we are leaking gas again. The petcock has some issues, but that wouldn't cause an overflow would it? I would assume the float would still ride and cut off flow. Any help would be greatly appreciated!
  16. Hi guys, I have EC 250 2008 racing and I have kind of rattle when idling and sticking idle. I set my mixture screw 1,5 turn out from fully closed and idle screw a lot in. Bike idles really fine no matter if cold or hot, but when I blip the throttle idle sticks higher and remains until I put gear and loose the clutch a bit or plug exhaust with my hand, than idle is back at normal speed. Can it be because air leak? I have sprayed chain lube on carb manifold and no change, so there is no leak, but maybe crankshaft seal?? Although I have rattle on idle that I think is normal for 2T but maybe not. I have very similar rattle on Husqvarna WR 125 which is after engine rebuild. Is it normal or not? Maybe rattle from reeds? https://www.youtube.com/watch?v=AIytJVgRp44
  17. Hey everybody, first post after years of lurking. Saturday I traded my johnboat for another bike. A very rough 2006 ttr125 with a 150 big bore kit. (no idea who made the kit). She starts first kick no matter what, idles and runs great until about 7/8 to full throttle where it proceeds to fall on its face until I let up. Bike has an "aftermarket" carb that i'm having trouble identifying. The only marking on it is an "M" cast on the side of the body. the insides look brand new but the jets dont have sizes on them. I can post pics as soon as I get off work but without knowing what size jets I have i'm not sure what kit to purchase. Starting to think a new mikuni would be the best course of action. Any Ideas or discussion would be great. Thanks a ton in advance. -Ricky

    IMS vs Stock Gas Tank Questions

    Hey all Thinking about picking up a new IMS tank, but have a few questions first. I have some aftermarket rad guards, could be unibiker but doesn't have the logo on it. Will the tank still fit with the guards? Since the tank is plastic compared to the metal stocker, does that mean you save weight when swapping? I do SM races so if I fill it halfway, does that mean the bike is lighter than before? If I have a gravity fed petcock now, will that still work on the IMS? How is the quality of IMS?
  19. I have a 2008 YZ450F with a stock header pipe and Pro Circuit T-4 Slip-On Exhaust. I'm 99% sure the slip on is shot because its loud as hell and when I take it off and shake it it rattles. I would repack it but the screws are all stripped ect. Anyways I've gone over the carb multiple times and I've got it running pretty well. The only issue I have with the bike is that it sputters and pops around 1/2 throttle when I hold it there. When I give it full throttle from any RPM it runs great or when I give it about 3/4 throttle it spins up like a top to redline. Initially the popping and sputtering was way worse I made the situation better by moving the pilot jet up in a few sizes from a 45 (stock) to a 62. The issue has gotten way better since then but I'm not super sure what to do from here. Should I keep moving my pilot jet up in size because that's a pretty large jump right? I tried changing my needle clip position but that didn't help much if anything it just made starting it worse and little to no impact on the ride. Any input on this would be helpful. I don't want to buy other slip on. Also as for the rest of the carb I'm very sure everything else in it is what it needs to be at. I've replaced all the gaskets and O-rings cleaned all the jets, valve holes ect. fixed the accelerator pump timing. I just thinks its strange that my pilot jet size is going so far from the stock 45, but all symptoms point to the bike running lean.
  20. So, what type of gas I you use on your 501? where I live we can choose between RON 95 and RON 98. I've been using 95 this far, not really sure if it will be any advantages with the 98. Anyone got any experiences they'd like to share?

    300rr, locked full gas

    Something strange happened with my 16´300rr. In a race with plenty of mud, after 30 minutes racing and accelerating at 3/4 gas, no more, suddenly the bike kept going like if I was full throttle. Scared, pulled the clutch and it over reved, thought it was going to blow. Moved the throttle thinking it was locked but no change. Had to kill switch it to full stop. Fast check, no harmed cable or anything. Started it with no problems, ride OK and 30 minutes later...again, , and then... again... 3 times on a single race! :?: :?: No visible damage anywhere, no locked cable, no locked throttle.... she just "kept going"... The most bizarre part was killing it, and starting like nothing ever happened without touching anything..... May be a spooky carb issue? I really have no idea, tomorrow I´m taking the carb off but I´m intrigued....
  22. I've wanted a 300 smoker for a long time, and now I've decided it's the time to do it. I've been already pretty much decided on a 2004-2007 300 EXC, but then I started browsing my local ads and noticed quite a few of these EC 300s for sale. I can get around a 2007-2010 EC 300 for the same money as a 2004-2007 300 EXC, that's why I've been considering it. Does anyone have experience with both of these, preferably these years? It's hard to find head to head comparisons on the internet for these two. Do the EC 300s and pre-2008 EXC 300s have an adjustable power valve? How do the engines and suspension compare? The only thing I've found out from my research is that owners of both seem to love their bikes.

    Gas Switch

    Hey All, This could just be me being a dumbass but I'm 100% sure that the gas switch is on PRI when it is running and it runs great, idols fine. But then I switch it to "on" and will be riding for a little and it the engine stops running and acts like it does when something runs out of gas. Any thoughts? Could the vacuum that sucks the gas be broken? Is it bad to run on PRI? Thanks
  24. prob a stupid topic but I'm interested to know more about it. I 100% always use Shell stations...no reason in particular. ...lately, when filling up, the pump won't automatically stop. I will end up over flowing. This has never happened to me up until recently, I usually always use the auto stop. Today it happened I had to tip the bike over to spill some gas out, I did use the reserve and it was getting pretty low. Not sure if my bike tells the pump to stop or if its the pump thats broken.
