Note to myself:
When instaling a Keihin CR 31 Special Racing Carburetor into your CB750, take it easy...
...the dry black sooty deposits on your spark plugs, are a warning that you are running an over-rich fuel/air mixture.
Conclusion:
Don't f*ck up your engine! If you don't know how to tune it, get the thing on a dyno, and get it tuned by a professional on the 21st May.

Well at least being a tad rich is better than being overly lean.
ReplyDeleteYou don't need a dyno tune, just do a plug chop.
You already know it's rich so get some new plugs and drop a jet size in the mains. Then do your plug chopping.
