I HAVE JUST BOUGHT A '92 MODEL XT600 AND i WANT TO PUT THE BIGGEST "BIG BORE KIT " IN IT WHAT SIZE CAN IT TAKE? AND WHERE CAN i PURCHASE ONE FOR BEST PRICE?


Stock bore is 95 mm, Wiseco offers a 101 mm piston, some crankcase cleanup is required. Will be 672 cc monster when you're done. Actually am building one right now for a supermoto screamer. Good luck!

What oil can you use for a wr400, 2000 model?


I use a synthetic 10w40 in mine. Amsoil is expensive, but I would rather change oil, than a piston. I race in the woods, and change my oil and filter every three hours of runing time. You can go longer for milder riding such as every 5 to 6 hours. Yamaha also sells a good oil, synthetic, and semi-synthetic.

Max size of cylinder


The biggest bore would be 1mm over.The standard bore on that bike is 65.0mm
so you could bore up to 66mm and to be a 900cc you would need a bore size of 68.5 mm
So your answers
  1. Yes, it can be bored
  2. No,Not to a 900cc
  3. Piston size is 66mm (making it roughly an 843cc)
I Hope this has answered all your questions,But please feel free to ask any more if needed.

Please take time to rate this fixya
