  1. Okay so to start off i know for a fact that it is a carby issue. Basically i have a 1995 Kawasaki Kx100 2 stroke, and its never ever had a single issue for the time that i've owned it which is over a year. Recently with the weather becoming colder approaching winter in Australia, the bikes been really really un-happy. First i noticed that is wouldnt start like it used to so i was like no issues, probably just the colder weather, then while riding it i realized it would bog out at full throttle, like a blubwubwubwub kinda bog. After a bit of tinkering i cleaned out the carb and stuff and tried to tune it, i came accross a different issue, now basically when im riding and i get to like 4th gear, all the sudden the bike will rev out really high and ill loose all power. Then i upshift into 5th and it will be good for a second then rev out and i loose power again. Ive checked everywhere for air leaks and all that and i cant find any. is my air adjustment screw letting in too much air? and in the case of the bog at full throttle should i maybe go down a size on the main jet. Lastly theres another issue lol. when i start it it will idle for a second and then rev its guts out. Please help me, next step is to get a brand new carb i think.

    2stroke kx250 brakes

    so im rebuilding my bike again as you can see in the before and now pics, im a creature of habit and when i ride i mostly use the front brake because of years on a street bike, im thinking i want to tie the front and rear brake both to the front brake handle and still have the separate rear pedal just like on my 2014 artic cat 4x4 atv, and if it is possible to do by stacking the banjo fittings or would i need a brake bias to make it work rite, if so any ideas on this ridiculous idea?

    2stroke yz250x noise at 5,000 rpm

    Hello all I've been trying to find this out for a while but i haven't been able. im trying to make a 2 stroke road legal but i can't find any easy way to see how much noise the yz250x puts out at 5,000 rpm the road rules say that it has to be below 95dba to be road legal in that aspect so just seeing if anyone knows.
  4. I recently bought a yz85 in great condition it just needed some carburetor work (the float needle did not seat properly). Now that that's fixed, I have a question. The bike is an '06 and the owner said "yeah it's still on the stock piston probably only has about a hundred hours on it" I cringed when he said this. But, nevertheless, I took a test ride and decided to buy the bike. When I kick it over, the compression is average for an 85 and it starts 2nd or 3rd kick cold and first kick warm. When riding it, there are no strange noises and I can hear no piston slap or anything out of the ordinary (listen to it in this video: https://www.youtube.com/watch?v=nx0VislGsg4&t=4s). I know a top end rebuild is a must on these 2 strokes so how has this bike lasted 12 years and still sounds like it's new? It doesn't bog, the only thing I have noticed is that it will hesitate while taking off sometimes when it's hot. I know I'm going to get the average "PUT A NEW TOP END IN IT NOW" 2 stroke guru, but is it really necessary? I have not taken the cylinder off yet but I put my finger over the spark plug hole and kicked it over and it has enough pressure to lift my finger but it's also really oily in there (oil ring left on my finger). So, what do you guys think? Does she got a few more hours or does it need a new piston ASAP?

    2stroke KTM sx150 or sx125 ???

    Hey so I’ve decided I want to move up from my crf150rb to a new 2 stroke and one problem I’ve had is deciding whether if I should get the ktm 150 or 125 and which is better for me I’ve listed my size and experience below and I’d love if you’d help me with my decision I’m 15 yrs old weight around 140 and 5’8 not much 2 stroke experience it will take time to get used to I’ve been riding for around 2.5 years now and I want a bike that’ll have good low end top end so I can learn and get used to the bike and I want to pick the best one for me either then sx125 or sx150 leave your opinions below thanks!

    2002 rm125

    Hey guys. My yz 99 deal turned out to be a 96 deal. So decided to look elsewhere and came across a very neat rm125 2002 model. Has fresh top and bottom rebuild. New clutch cable and throttle cable. I love the look of it minus the pipe whats your thoughts? And any ideas on updating the look?
  7. Okay i have a 1994 KTM 250 EXC my clutch works perfect when shifting but if the bike is stationary and off when I am in gear and pull the clutch the bike won't move it works fine when it is running but if I went to bump start it or even just push it around without having to be in nuteral it won't work any suggestions?
  8. I’ll be moving to Oceanside, CA area fairly soon. I’m looking for trail riding spots that have awesome views along with some gnarly terrain. Willing to travel 3-4 hours if the spot is worth it.
  9. watch a short video of a Full rebuild of a 2 stroke bottom and top front to back , repainted, polished and refinished and rebuilt CR125R, this is the first year of engine water cooling, single mono shock, hydro brakes and the last year of the Special edition Elsinore 125cc 2 stroke racing dirt bikes.
  10. In advance of getting my first 2-stroke , a 2000 YZ125 off the bench I'm watching a lot of videos of two-strokes trying to get a sense of how they are ridden. One thing I've noticed is that riders blip the throttles is a way that seems to be unique to 2-strokes; they rotate the throttle then open their hands letting it snap back by itself. I've never seen this done on 4-strokes. Why is it done on 2-strokes?

    KTM 200 making weird noises

    Hello everyone, So about a week ago I was riding when my bike seized. I brought it home and took of the cylinder. Nothing seemed damage, I checked crank bearings, piston bearings, everything I could without splitting cases, and so I just cleaned everything and put it back together. When I start it, it seems to have more "resistance" however I didn't replace the piston so I shouldn't have m,ore compression. When it starts it makes a terrible sound like engine knock but I checked the crank bearings. The sounds is loud and clunky. If I let the bike go into low RPMs it just dies and almost seizes. Any ideas would be great otherwise Ill bring it into a shop. Thank you!

    YZ125 cdi problems?

    I have a 2006 YZ125 that I bought new back in 06, I have went through the whole bike recently and everything is in good shape. Checked all the electrical system and it is up to spec. cleaned the carb spotless inside and out. Stock jetting always worked fine where I live. So for about 4 years now I haven’t ridden the bike but a few times and now I noticed that the bike isn’t running right when you snap the throttle it hesitates too long and just doesn’t have the throttle response it had before. Also when I looked at the head it was pitted some from detonation. I have read in here that a few people have had cdi trouble on the YZ125 and 250, if you have can you share your expirence of a bad cdi with me? I’m hesitant about buying one cause you can’t return electronics even if they are faulty also if anybody has a cdi box 2005-18 they would sell let me know, thanks

    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.

    Lack of Power

    Hey everyone, I am new to the world of 2 strokes and I am having an issue with a 1996 CR250r that I recently acquired. To begin with the bike will bog down when I first hit the throttle and will do so again if I let it sit for a bit. However the problem goes away if I am constantly on and off the throttle. The larger issue however is that the bike seems like it is hitting a rev limiter at 3/4 throttle and the power is lacking for a bike this size. Id appreciate any help in trying to figure this out.

    What bike is best? YZ vs CR

    Hello, The question that I see alot of people asking all over the internet. some think one way others say the other, but what I get from it, It depends on what riding your doing and where. So I would like your opinion, would it be better for me to get a YZ125 or a CR125 im 5'7'' and somewhere around 120 to 130 pounds. Im going to be doing mostly woods and trail riding. I am also looking at other bikes but this is just between the CR and YZ 125. Thanks

    2000 kx 60 float issue

Can anyone tell me that the spec is? or what they run theres at. Also please let me know if it could be caused by something else. thanks

    Exploring Trails

    Made a little video of me riding some new trails we discovered, I had no clue where I was going. But I found out a way to ride a pretty fun loop to practice for woods races on. Check the video out, feedback is appreciated

    Looking to Advance

    Hello all, new to the forum here and I'm excited to get my first post up. I am currently faced with the issue of progressing as a rider. I am 5'9" 155lbs and have been riding for about 4 years now. I currently own a 08 Honda crf230l and would say that I do mainly trail riding and enduro. I do commute to work occasionally but I wouldn't say that I absolutely need the street legal half, although it is convenient at hell. However I am at the point where I feel that I would progress much more as a rider with a different bike, for I feel that what I have isn't quite geared towards what I am doing. The bike almost feels heavy a lot of the time when riding and pretty unstable, especially around bends and gnarly terrain. Hills are always a challenge but the bike can chug its way up. I wouldn't say I'm a super aggressive rider, I'd say moderately aggressive, but then again that may be because of what I'm riding. Maintenance is no issue, I've been around the block and have been able to manage anything the Honda threw at me so I'm not really worried about that. My price range is anything under $3000 I was initially thinking about getting a trials bike to hone my skills in but now I'm thinking that I may just want to save my money and move toward a 2 stroke enduro bike, maybe something along the lines of 200 exc . I just don't want to have too much power and be out of control on the tight trails. I would consider a 4 stroke but from the research I've done, a 2 stroke with a heavier flywheel weight set-up is the best route, but I've never ridden one and don't know a ton about 2 strokes. Any thoughts and input would be greatly appreciated.

    YAY more peewee Probs.

    Hello guys. I recently picked up a 2000 something PW80. I put on a new top end(jug,rings,piston,plug, etc.) and a new carb as the old one was thrashed and had stripped bolts galore. My problem is i get a gnarly bog at about half throttle in all gears except first (mostly because first winds out before i reach half throttle) and it smokes like a mother ***. Also lots of oil build up in exhaust, nearly dripping. a few things about the bike. holes in airbox, exhaust washer and silencer removed, new top end, carb, removed the autolube system. i have to admit the carb was 12$ haha but it was nearly an exact replica of the stock one as i could see from the pics. im guessing its running hella rich from the plugs and piston already having black build up. my friend has an 1985 pw 80 and i used his carb on mine and it did nearly perfect except for the top end bog a little so i knw its carb related but im not sure what steps i should take from here. Thanks in advance for taking the time folks.

    Clutch problems

    Hey guys, jut did a bottom end on my 04 yz 250, and the clutch won't engage. What I mean by this is it will start in neutral, and once I drop it into first (with the ever pulled) it stalls out. When I depress my clutch lever the actuator is fully engaged, so I don't see that being the issue, I've read that sometimes after you take out or put in clutch plates they stick because oil hasn't flowed through the plates all the way yet. I'm at a loss, any help is appreciated! Thanks in advance
  23. Hi guys, i have recently just bought a 2004 yamaha yz125, it has an athena 144cc big bore kit. The bike runs great! It has a loud knocking sound coming from top end but vibrates the clutch plate too. It speeds up when revved but goes quieter, also the sound dampens when the clutch is pulled in. The sound wasn't there when i bought the bike, then the knocking came after the second time of taking the bike out just up a lane. I have taken it out once to a proper track with this knocking sound and no problems or changes occured. By reading up it could be piston slap, but also many other problems. I don't know how long for sure the kit has been on the bike but the fella who i bought it from said "i think a year", but don't know of any care to the bike within that year because he was selling it for a friend. If any of you could help that would be great! And do i need to be majorly worried about this? Thanks
