I tore down my 00 wr400 and found a slightly scored rod and a bad counterbalancer key.

I want to rebuild it with a big bore and auto-d cam. I want to go with a 426 rod.

Have 2 questions can I bore a 400 cylinder 95 mm for use with a 426 piston,rod and pin or must I buy a 426 cylinder?

2nd question, who can I use to rebuild the bottom end and crank on a fairly quick basis. Eric Gore is unreachable.

-Thanks

SXP is a local riding buddy and knows his stuff. PM him if you have more specific questions. I'm hoping to have a Lukes Racing 444 ride report this weekend, as long as the final assembly goes without incident. I'll let you know what I think if you're interested.

The bottom end bearing is different sized if I remember correctly. THus you need a whole 426 crank then you need to see if the main bearings are the same size.
