He'll yeah do it Blasters are a dime a dozen and can be bought for under $1000 all day and even if the 426 is a project it's beTter to have a garage ornament then a blaster IMO

Blasters are lame, have no brakes, and unless you are 4ft tall,weigh around 100lbs in gear, and throw a load of cash at them they arent worth riding. Stick with your project bike and do what you can as funds and time allow. The 426 guys really love them. They all cant be wrong.:smirk:

If the piston touched the valves you may need to replace all of the valves. Considering that it's a 2001 426 the OEM valves are titanium and not cheap. At all. Also, the valve guides may be bad as the valves may have bent and damaged the guides. Your options are to replace the complete valve train with OEM for ~$600 if you search eBay, or get SS valves from a '98-2000 YZ. If you get the SS valves you will need the valves, springs, and valve keepers. It will be a lot cheaper than the ti valves, that's for sure, and you probably won't notice any loss of performance. You will want a new cam chain, too, and they only cost $35 from Yamaha. You might not have to buy a new piston because the valves usually bend before the piston gets damaged. That will save you $130 or so.

Since you are in there, you may want to drop $150 on a new exhaust cam with the auto-decompression. It supposedly makes it easier to start, but I haven't found a need for it.

Post up if you have any questions and good luck! These bikes are awesome when they run right.

I can't disagree. I've seen people riding blasters and there for 12 yr olds. I also just purchased a 2000 yz426. This weekend was the first time I really got to ride it and I absolutely love it and you will to. I'd go for that deal. There are plenty of people on this site, including myself, that have rebuilt these bikes and have the knowledge to help you through it. Good Luck!!!

      Selling an FMF Power Core 4 exhaust system off my 450FX. Exhaust has 80 hours and is 100% functional. This will also fit the 14-15 YZ450F and 16-18 Wr450F. If needed I can also include new muffler packing although it does not need it.

      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.

      Hi I was wondering if y’all have been using a 450 on your YZ250F?

      Excel Takasago 17x3 front and 17x5 rear supermoto wheels with Metzler M3 tires in very lightly used condition. Less than 200 miles total on the setup. Warp 9 spokes. Rear has a Talon hub with 45T Sunstar steel sprocket and OEM rear disc, and front has a polished OEM Yamaha WR450F hub (for the stock speedometer), with a Motomaster 320mm disc. Included is a DID gold o-ring chain, 14T front sprocket, and front brake caliper adapter for a truly turn key setup. Everything is in excellent condition, not a single scratch on these wheels. Came off my '11 WR450F, but will fit many different Yamahas with 20mm front and 22mm rear axles. Asking $1400 plus shipping.
      **Will be driving up near Atlanta, then to northern Louisiana, OKC, and down through Dallas and Houston, TX soon -- can meet or deliver if in the area (Aug 31-Sep 9)**
