I recently switched from the yammilube 2-r to castor 927 (kept same ratio, drained/cleaned carbs, cleaned filter and drained tank) and it ran great for about 1 to 1 1/2 hours. Then I hop on the bitch the next weekend (w/ 5 minute warmup) and tear off into the pasture kick ass as usual.... slow down to powerslide around my hairpin turn and it goes buuuur buuuur bloop when I pinned it. So I managed to get it back to the casa and threw a new set of plugs in it. Ran kick ass the rest of the weekend, came home the following weekend and the SAME SHIT HAPPENED!!. I'm thinking that those cheap ass b8es plugs just foul up to easy so I called around a 50mile radius and 1/2 the people tell me that the b8eix and b8ev DON'T EXIST . Is it my plugs or should have I changed something when I switched the earls?
BTW: I'm runnin it at 36:1, 310 mains, 27 pilots.... same setup that 'shees had since ive owned her. I've always been told this is better oil... should I just say f*ck it and go back to the 2-r or is there something else wrong?
