take the bike for a good run 15-20- miles and do a plug chop see how it is running before making any adjustments ,,, or place it on a rolling road with a gas analizer up the exhaust

Would these suggestions still be the same if you add a 1075 wiseco kit into the mix..

ie, MK2 engine, 1075 wiseco, kerker and K&Ns

Was going to send my carbs of to be overhauled/tarted up and obviously it would be a good time to change the main jets.

Are there any other adjustments to be made to pilots / airscrews etc
