I have just bought an '02 WR426 and was wondering if its nomal for the exhaust to glow red hot where it comes out of the head ?

If you start the bike from cold and let it idle for 10-15mins it will do it !

Also, I have seen alot of pics of the 426, some have a big tank and others have the yz smaller one like mine, have people fitted the smaller one or is it standard on the '02 bike?

Mnay thanks

Sorry, I should of said why it was idling for so long, this was when looked at the bike before I bought it, no intension of doing it in the future !

The guy reasured me it was normal and though i heard it before ! :applause:

I have spent hours searching for more info on the 426, everthing seems to be about the 250's or 450's, the bike has a YZ end can ( I think, says 'not for road use on the rear) I will check the gray wire tomorow but can anyone confirm that the gray wire mod is safe for the 426 on stock jetting etc?

Many thanks :bonk:
