Didn't impress. 4 strokes aren't my cup of tea. -

I love this bike. Got my first dirtbike a few months ago (02 YZ250) and I liked it, but wanted to try a 4 stroke. Traded the 250 for this 426 and I absolutely love it -

I bought this bike in 2009 for $1400 and it's been awesome! It has gone through two rebuilds and eventually ended up in its current dual sport (CA Street Legal) configuration. -

I think it's a great bike. It was hard to get used to at first just based on the shear size and weight.... Once you get comfortable on it it becomes an amazing machine that you can hit up the mx park or go riding around on some long distance trails. -

Hey thumpertalk users.... im in a bit of a pickle here.... im a 15 year old who recently acquired a 2001 yz426f. now this bike is a real pain in my ass. I was buying it as an extra bike as i already have a 2001 kx250 as my main bike the 426 was going to be a bit of an extra bike that my dad or i could ride if we felt like it on occasion but me being a fool bought the bike for $1150. when it didnt run right. With my 2 stroke mind i thought oh easy fix ill tune it up and go throw some rooster tails with it. WRONG. I got the bike and the way it was running it was super hard to start and is has a hot start cam/ auto decompression cam in it and it would start when i gave it a ton of gas and it ran really crappy til about quarter throttle then it ran great it did wheelies and whatnot no problem. So i decided to do a valve job and apparently did it wrong cuz i started it and it knocked literally like a woodpecker on a tree. it was the worst sound i have heard come from a dirtbike. SO i took it to a shop and got a valve job and a carb clean with the idea that the valve job would fix the knock (or so they told me) they did all that and it still knocked REALLY bad but it ran good. They did another diagnostic and are now telling me that i need a new top and bottom end and a connecting rod as well as a replated cylinder. Keep in mind i have not actually yet scene the damage and i kinda think theyre totally bullshitting me but you guys tell me what you think. Now so far ive invested $1628 into this piece of absolute crap. i REALLY would like to keep this under $2000 and im considering all options (btw if any of you would like to buy the bike i would love to get rid of it im in Los Angeles). Anyways could you guys tell me what u think the best option here is because its really stressing me out because its actually my money and its alot of money for a 15 year old to spend.... all advice is appreciated thanks guys!

I have a 2001 YZ426 that will not start. It is a friend of mines and we have been working on it for about a week. We have completely cleaned the carburetor, check and shimmed the valves, checked timing and reset it. It has fresh gas, good spark with a brand new spark plug, It is getting fuel all the way through the system, we can't see anything visually wrong any electrical parts. We have tried kicking and kicking, bump starting, pulling it. We have tried using a little starting fluid. We haven't got any kind double roll on the motor or any sign that the motor is trying to start at all. We don't know the last time it ran, He bought it from a guy who never got it start although didn't know what he was doing, and the same with the person before him. If you have any advice it would be very helpful. Were hoping to not have to tear down completely.

3/4 of the way thru it. Had hoped the FCR carb could be left alone but of course, the slide was sticking thru top half of the throttle cycle so complete tear down and rebuild. -
Just picked up a plated 2002 wr426 and love it but it is way too loud for the neighborhood. Attempting to ride to work at 6am without making too many enemies... The current exhaust is a "Zip-TY Signature Series by Flow". It has a spark arrestor and Ive repacked it but its nowhere near what i'm after, cant pass by without people looking to see who the A**hole is. Ive attempted to research the manufacturer in the hopes of finding a compatible insert but have come up short. https://ziptyracing.com/ Anyone know about this exhaust? and db killing solutions/ applications? Will the pro circuit quiet insert type product give me any negative db results? (see below link) https://shop.thumpertalk.com/pro-circuit-racing-intl-stainless-quiet-insert-4-x-1-replacement-part-794-9024.html My ultimate want is to find a FMF Q4 or at the least a FMF PowerCore to throw a silencer tip into if that would get me lower. I have scoured the internet in search of a fmf q4 but cant find anything... used or new. Can anyone point me in the right direction or have one laying around? My other option is to buy an old stock wr426/400 exhaust. Based upon looks, this welded shut chamber and pea shooter tip seems like it would be quiet but also incredibly restrictive. Ive found a few on ebay labeled "yanaha 5bf-10", one is listed as an oem yz pipe, the other is listed as an oem wr. Im figuring its a WR based on the other OEM yzs that ive seen. https://www.ebay.com/itm/Yamaha-WR426F-2002-exhaust-muffler-silencer-baffle-5NG-10-2001/324274137805?hash=item4b803eaacd%3Ag%3AfykAAOSwVXNfRqIC&LH_ItemCondition=4 Any and all help is appreciated. Trying to make the essential work commute a little more fun during this covid nightmare.
