Mikuni 40phh tuning

Post by glitchinq »

So I'm picking up a pair of mikuni 40 phh carbs and I was looking for some tuning tips. I have a pretty good knowledge of tuning carbs on these motors but have never messed with side drafts.

Msd ignition.
Carb was jetted or was ran on a similar built motor with just a 284 cam.
