The cranks can be rebuilt with new rods and bearings etc . Read the tuning section of the forum and it will give you a guide line on how to do jetting .

@ Neal - I know the MC18 harness does not support the GPS. Thus, I have adapted it to work... Neutral works on the same principle as the neatral switch on the MC18, when it's in neutral the circuit runs to ground... simple. I have in addition to this utilized the other gear positions on the sensor to work with a custom built LCD gear position display. As for modifying/machining down of cranks, not really keen, I firmly beleive there was method in Honda's madness to increase the web size on the MC21/MC28 crank. I'd rather stick to my MC21 bottom end running MC18 barrels. I will at some time have the R5K/R6K crank repaired as I have secured a shipment of bearings for a local supplier, then I might be interested in those casings, i'll keep you in mind.

As a general rule of thumb, if in doubt, start out rich and read the plug before going leaner.
There are a couple of pictures of spark plug colour here, if that helps?

@ TuckerBug - Thanks, I'll check the plugs as soon as I get it up and running, just waiting on barrels to come back from replating. Did you receive my email I sent you?
