I have been battleing tuning my carbs for awhile now. I jetted up on my pilot jets last night. 42.5 to 45 137.5 on mains. I started the bike alittle hard starting, popped every now an then. Raise rpms to around 1500 to get ready for adjustments did the dead cylinder trick. But the bike would stay running when I lowered the rpms. So I hooked back up the plug and figured I would let it warm up a bit. Well the exhaust whent from blue to purple and then the purple kinda whent away and I noticed a red color so I shut off my shop light and the exhaust was red!! So I shut the bike down. Even before I turned on the lights... Well I pulled the carbs off again and there they sit on my bench tore apart... 1980 bs34s brass float.
