Re: Rebuild a cbr400
Hello - apologies for the delay in approval!
Would suggest you look in the documents section http://www.400greybike.com/docs.htm
there is a range of clearances for both inlet and exhaust - would suggest you get a look at the manual, or a haynes - you really don't want to be getting it wrong.
The shims will be used according to the measurements taken so that you can get them into the tolerance.
You need - feeler gauges and a digital vernier
good luck :)
