    KTM 300 odd sound when revved

    Bought this bike a few weeks ago and just started making a weird sound when revved, hard to explain but I will post a link at the end. Never had a problem like this before only noticed it when I replaced the stock silencer with a FMF powercore 2. Mind the dirt I wanted to record the sound after a ride Any help would be great, Thanks
  4. Hi everyone, new to the forum seeking advice. I want to buy another bike. I've been riding a 2002 KTM 520 EXC and it's been a great bike but looking to upgrade to a newer 500 KTM or a 300 XCW. I ride mostly Northern California single track, double track, and occasionally fire roads. Having a plate is not a priority since I have a plated xr650. I'm 6'3'' and have always ridden big bore bikes, so bike weight hasn't been an issue....But I haven't ridden a 300 yet, and I hear they're awesome. Which model would you buy? Should I look at a Husky? If I buy used, what year range is best? Thanks!

    KTM 2-stroke Overheating

    I'm caught between a rock and a hard place. My 2010 KTM 250 XC won't stop peeing coolant out of the overflow tube. I've used 3 different radiator caps (two of the oem 1.8 bar caps and one CV4 2.0 bar) and it still continues to pee coolant as soon as the bike starts up. I just recently bought and installed brand new radiators [GPI on eBay for $88 (the seem fine just the welds are a bit crappy and you can see inside of the tubes where the metal from the welds drooped down but there are no blocks)] and silicone hoses (profactory hoses) thinking they were the problem since the old radiators were bent in like bananas. To my dismay that was apparently not the issue. I've had everything apart and looked at. Has brand new base gaskets, head gaskets, radiators, and radiator hoses. I've bled the radiators like the manual says and there are no bubbles like air leaking into the system or being in the system. The jetting is also perfect. The only thing I haven't changed out is the oem impeller in the water pump but it looks to be in great condition. Any ideas on how I can fix this problem before it gets worse? Also, has anyone else had this problem and figured out how to fix it? I ride it in mostly tight 0-10 mph trails and also some 10-20 mph trails.

    My work closed down due to snow for the second time in 3 years today post some pics if you had as much fun in the snow as I did
  7. I have the following issue on a brand new 2019 KTM XCW 300. On low RPM, the engine is sputtering (sorry if I can't find a better word, I am not a native speaker) It feels like a cold engine but all the time, even after 3 hours of riding. Apart from that, the engine is a beast and if I open the throttle a bit then there is no issue. I tried updating to the latest firmware + change the reed valve from stock the vforce and back to stock again with no success. Any idea what might cause this and how to fix it? Here is a video of the issue:
  8. Hello guys, I’m Marco from Italy, it’s a long time that I’m reading various posts here in the forum, they are very helpful, so I’ve decide to ask you for some suggestions. . I'm writing brcause ask for advice for the Showa 47 ex CRF450R that I took to mount them on a Beta Xtrainer (which as you it comes with poor suspensions). The Beta as long as you go slowly behaves very well, then as soon as you get up the pace becomes not very stable, so I found these Showa close to home very well placed at an honest price and I decided to buy them. What has been done up to now, as well as a complete overhaul, has been to shorten the stroke from 315 mm to 280 mm to respect the original geometry and replace the springs with 0.42 kg / mm. Now, I imagine that the hydraulics, is quite sustained so before installing them I wanted to put my hands on the shim stack but without spending a lot of money since I use the bike only on the weekend and I do not have to race, the initial idea was to copy the pyramid crf250x but I thought that maybe intervening on the shims present you can do something without upsetting the configuration too much (like removing or moving shims). This is my basic configuration, http://i63.tinypic.com/9qgw48.jpg, if you have any advice on how to move it would be welcome, even combining preload spring and oil to be inserted into the forks. What I was looking for is to get a slightly softer fork in the first part of the stroke and reading around I seem to have understood that already intervening on the bypass something is obtained. To finish weight about 72 kg without enduro garments, so around 80 kg dressed in overalls protectors and boots. Thanks a lot in advance and happy holidays to everyone.
  9. Hi guys, I'm finally picking up my 2017 300RR before the weekend and I'm trying to work out which mods are essential for this bike. Of those essential mods I'm also looking for the brand of choice. I'm based in Victoria, Australia so any suggestions for parts that are quickly and easily available here would be awesome! Thanks!

    2003 KTM 200 EXC Jetting

    I recently bought a 2003 and tore the carb down just so I knew what it had for jetting. I found a 178 main, 48 pilot, and NOZG needle on 2nd clip from top. (Bike has totally stock exhaust and riding is about sea level). The 48 pilot caught my eye as I thought it should have been more like a 42 and was wondering if this is correct? Also what is the best needle to use and on what clip? Any help is appreciated, Thanks.
  11. Hey Guys, I am posting to see if anyone else on here has done the 300sx top end kit on their 250sx. I installed the kit last week to my 2014 KTM 250SX with 40 hours on it and wound up with a really bad vibration, the bike shakes so bad when you twist the throttle at idle that the foot pegs jump and the bars get a 3/8" oscillation to them. Before anyone says "its a 2 stroke they vibrate" I also have a 2014 300XC and it is 1/8 of the vibration that this thing has, also It didn't vibrate all that bad as a 250. Has anyone insalled this kit before, did it drastically increase vibration? Is the 250sx crank the exact same crank as the 300xc or is it a diffrerent crank with different balance? Has anyone gotten a crank for a 250sx balanced to the extra weight of the 300 piston? hoping someone has been through this before. Thanks, Jordan

    Used bike initial maintenance 300xc

    I am buying a used 2014 300xc from a local seller. I am looking for some advice on the initial maintenance that I should perform after picking it up. Background: His dad bought it new in 2014, selling it to him in 2016. He is selling it to upgrade to a 2017. The seller raced recreationally in some local enduros. The motor is untouched. Never rebuilt top or bottom. (seller said he guessed 70 hours, but I assume it's much more) It has a bent radiator (not leaking). New pipe. New Silencer. Says he just replaced the clutch pack, chain and sprockets. The bike looks heavily used, but for agreed upon price I am happy with it. What are the must do maintenance items I should perform before riding in the spring?

    Ktm 300 reed petals breaking

    Noticed that my 2007 ktm 300 was bottoming out with no real power and looked at the reeds(Vforce3) and the petals had a chip in one of them. I bought some new petals off of a ktm dealer and used them for about two hours bbefore the exact same thing happened. What could the cause be?
  16. Can you ask for a better gift under the tree than 2 of these? My son and I picked these up the other day after many hours of research and reviews. 250 XCs were on the top of the list until we came around and chose these for our 6'+, over 200lb frames. We couldn't be happier to have the opportunity to assemble them ourselves. Recall that lucky guy who recently won the Sherco 300 SER from Dirtbikechannel? Yep, my son drew the lucky number. That Sherco is what led us to the 300s. We loved the playfulness of the 2T and how light and agile it felt even though it was heavier than our 4Ts. It was just was too awkward, buzzy and unique for his taste so it went to a good home and the funds put into the TX300. I myself had a 300 listed as my dream bike so when he began the hunt I couldn't let him bite alone, hence two in the assembly area! We've got many memories to make on these together. We've already ordered some goodies as I know my bike will be with me a long time so the investment is warranted. Upgrades such as: Lectron Mule, AXP full skid plate, Turbinecore 2.1 and some smaller mods. Now to get back out there and finish assembling it so we can ride!

    michigan Michigan has some kick ass Trails!

    We have been going on adventures every other weekend riding everything Michigan has to offer within a few hour distance of where we live. This is a short one of us playing around on the Moss Lake trails in Rapid River MI. It's not a bad trail, a little choppy for how many roots are on the trail but none the less fun as hell!

    2018 KTM 300 XC-W OTD Pricing

    For all of you lucky enough to own an '18 300 XC-W, what kind of deals could one get around this time of year? I know the '19s will be launching within the next few months. I'm wondering if I should wait until their release and save $$$ on a leftover '18. I'm on the eastern side of the U.S. by the way. Let's see the final OTD numbers!

    Checkpoint Waterpump Impellers

    Has anyone installed and used a Checkpoint impeller? I see dirt rider had an article about them and I've been curious about them. I've been having overheating problems recently and after spending well over $200 on brand new radiators I've discovered the radiators weren't the problem. So I bought new piston rings since they were out of spec (supposed to be like .15 and they were .5) and then thought about buying one of these aluminum impellers to help the problem instead of keeping the flimsy plastic one. I've read mixed reviews about them. Has anyone had any luck with them or is it basically just paying for the same overheating problems to happen?

    500 EXC TO 300 XC OR XC W?

    Hi, coming over here from the four stroke forum. I'm comming off a 500 exc and am torn between the 300 xc and xc w. I know it's probably a question that has Been asked a thousand times, but I have been doing searches here and elsewhere for the last couple weeks and can't seem to find any good info to sway me one way or another. If I had to pick one based on the info I've read, I would choose the xc. FYI I live in Pa. and ride mostly wooded atv trails and single track. My last 2 stroke was a 1991 300 mx (I LOVED THAT BIKE). Thanks for any input.
  23. I'm and intermediate rider who rides very aggressively and on hard, but fast-paced woods/cross-country/harescramble riding. Sometimes I'll do technical, really tight trails, log crossings, and hillclimbs, etc. and I also will ride motocross tracks every once in a while. I currently own a 2008 KTM 250 XC-F with a bigger rear sprocket, FMF exhaust, aftermarket piston, and I typically run high octane fuel. I won't be upgrading for quite a while but I am planning ahead trying to decide what to save up for and all that. I'm sure this forum will also help others in similar situations. I'd like something that can top out faster than my bike but something that can accelerate quickly and have more torque as well. The majority of my riding is very fast-paced woods with hard corners and lots of roots and steep hills as well, so I'd like something that can blow through corners and accelerate quickly. But, I also ride a lot of tight technical trails so I'd like something that's torquey and has explosive, yet controllable power and something I can take over big logs and rocks. I'm fine with a bike that likes to be revved a lot as that's what I do on my 250xcf now. I'm used to four strokes although I'll probably adjust to a two stroke very quickly as I ride constantly. I'm leaning towards a 250 XC or a 350 XC-F although I've heard lots about KTM's 125 and 150 2 strokes, the 450 and 500, the wide ratio "w" models of the cross country bikes, and their respective motocross models just because I know how explosive they are. I understand that this is a lot to ask out of one bike but I'm going to be adding a lot of aftermarket parts to whatever I end up getting if it doesn't already have any. Tell me all about these bikes if any of you guys have ridden them! I'm probably going KTM because I've heard nothing but good things about them but I will still consider any other brands as well. Tell me any aftermarket you had to do, improvements to be done or downfalls of each bike, and all their advantages and things they're better at than the other ones if you've ridden more than one of these. This is more of a harescramble/cross-country racing post, but since some of my races have parts of motocross tracks I'd like to hear how they do on the track. Also, money isn't too huge of a concern with me but I will definitely not be able to get a brand new bike. I will be racing so if it's bigger than a 250 then I'll have to be sure that it can compete with bigger bikes. Thanks, in advance!
  24. 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

    2008 KTM 300 XC-W Rebuild

    Hey all, I have a few questions. I just sold my 2002 KTM 380EXC and bought a 2008 KTM 300 XC-W with 373 hours. I did it because I didn't want to have to figure out how I was going to come up with money to do a crank rebuild in the future. But anyways I love it, although it isn't a 380. It has crazy CRAZY torque. I loved the power from the 380, and was kinda disappointing not having all that power right from idle, But the ability to actually lug the motor in the low RPMs and not stall the bike or boil it over... EVER. Made me pretty dang happy. Also the 300 is much quieter than the 380. Must be those extra ccs that contibute to the noise. Anyways, the other day I rode my bike around to warm it up, then let it idle for about 5min while I got my gear on... Right before I took off, I heard a Squeal and it shut down. I go to kick it again and it's stuck. I pulled it apart, and it wasn't the top end that was Seized, but the bottom end that was. I was able to wiggle it loose after a few turns but when the crank turns it isn't 100% smooth which tells me it must be one of the bearings. So I guess I'll be doing what I had planned all along. So back to my question, now that I will have the cases split, should I replace all the Transmission bearings along with the main crank bearings? Or do I never really have to worry about the Transmission bearings? There's a full Wrench Rabbit kit for $620 on ebay, which includes all bearings including transmission bearings, or should I just get the bottom end and top end rebuild which is close to $500? (I was planning on doing both top and bottom anyways).
