GearNut,
Thanks for your advice as always. I've got a box full of plugs (mostly the ones that come with the kits) that are all dark from running rich at one point while tuning. I have 2 good NGK plugs that are dark as well, and I can't justify buying another good plug just for tuning the carb.
I'm trying to figure out how other people do it, because once the plug is dark it won't lighten back up right? At least not in a short test run? So should I start out intentionally lean in the future and then get richer until the plug is dark enough tan color?
What is a good cheap plug I can find locally just to test? Actually...where can I find NKG BH*S or BPH*S plugs locally?
Sorry about the barrage of questions! I was running rich on purpose for a "break in" and because I read some people say that they'd rather run rich all the time and extend the life of the engine..."oil dripping from exhaust is normal".... etc, etc.. Only I really soaked the fiberglass in my expansion muffler to the point it was leaking out. I opened the muffler to replace the fiberglass and left the **** thing at Home Depot last night looking for replacement screws! Ahhhhh! Man.... These bikes really are a constant project. I don't think I'll ever get one "done".
