B.b.p builders Posted July 7, 2014 Report Posted July 7, 2014 This is after 2 passes on brand new plugs bike was shut off at end of pass. I've been researching methanol plug reading, but I'm still not getting a straight answer on dark like my plans is lean? Or ritch? Quote
B.b.p builders Posted July 7, 2014 Author Report Posted July 7, 2014 I understand enough that this is not what I want my plug to look like. I know I want it to look new, for atliest 90% of the upper ring, but what I'm not finding is if now I am lean, or rich? Carbs are lectrons Should the needle be moved or only the power jet? Quote

troyzstang Posted July 7, 2014 Report Posted July 7, 2014 Still learning myself but I read the strap and the circle around the end of plug. Strap identifies timing and circle identifies heat. Looks like you're really learning a lot. Hows the tranny doing ? Quote
B.b.p builders Posted July 7, 2014 Author Report Posted July 7, 2014 The tranny is holding up! You wouldn't believe the hours I put in!! I have the hang of pulling in the clutch! Hopefully it last I have my first race in 3 weeks! I will buy another one to have on hand when it lets go. Quote
special06shee Posted July 7, 2014 Report Posted July 7, 2014 Hmm. Mine looks nothing like that. Im still learning alky myself.. Mine look like brand new after a couple passes. But i also know im super phat. Quote
slobanshee Posted July 7, 2014 Report Posted July 7, 2014 Rich - plug looks brand new. I aim for half the plug to look new and clean and other half to have brown color..... That looks lean to me.. 1 Quote
dozer Posted July 7, 2014 Report Posted July 7, 2014 no expert but that doesnt look good to me. mine would look new still after a couple passes like others have said. Quote
dozer Posted July 7, 2014 Report Posted July 7, 2014 (edited) When it burns the strap off you are too lean. truth. if you're really lucky like i was at ls last year you just throw new ones in. if not you get to buy pistons, domes and plating. keep it on the rich side.

#1JUANstunna Posted July 7, 2014 Report Posted July 7, 2014 I'd prefer rich and leave some hp on the table than the alternative. Quote
B.b.p builders Posted July 7, 2014 Author Report Posted July 7, 2014 Have those been purged on?No, brand new, 2 passes. I have decided to use different plugs to purge until I get this thing dialled in. Quote
B.b.p builders Posted July 7, 2014 Author Report Posted July 7, 2014 Rich - plug looks brand new. I aim for half the plug to look new and clean and other half to have brown color..... That looks lean to me..It makes no sense that it is LEAN like you say, cause the next run I leaned the power jet 1 turn in, and performence was better, and plug was starting to clean up a touch. Can any veteran methanol runners chime in? Quote
B.b.p builders Posted July 7, 2014 Author Report Posted July 7, 2014 Actually running a lil rich with alky will not lose power like gas. You can however lose power by being lean. Especially if there's a hole in piston from itNo doubt. I agree. Also I just read that with methanol color on the plug (like the color of my plugs pictured) is cause by heat from being too lean.

badassbanshee479 Posted July 7, 2014 Report Posted July 7, 2014 What oil and at what ratio are you running? Those plugs look really lean... The heat going down the treads like that is not good Quote
