Oilyspanner Posted June 19, 2020 Share Posted June 19, 2020 I'd check what jets you've got SFC, 148 would be a dynojet size, not mikuni, it might have d.jet kit fitted - you can only use their jets with their needle jet and needle, they flow differently to the mikuni jets.Mixing d.j. and mikuni is a nightmare, a real arse ache ! Most running is on pilot and needles - does it run okay at tick-over, low speed cruise and moderate throttle opening and revs ? Check what jets are in the carbs because that changes any settings given. Mikuni jets have the square in a square logo on them, jets go up in 2.5 sizes (ml per minute) - I think dynojet normally have dj plus numbers on them and sizes go up in twos (based on measured diameters and not flow). 1 Quote Link to comment
Gixer1460 Posted June 19, 2020 Share Posted June 19, 2020 IMO - yes DJ size and waaaay too big for a near enough std engine - I'd try 126 - 130 mains. Emulsions / needles could be worn which also won't help and promotes rich condition. If they are DJ - they have a lifetime warranty & free replacement! 1 Quote Link to comment

SFC Posted June 22, 2020 Author Share Posted June 22, 2020 (edited) Not sure but the oil pump failed and smashed then dried up me cams. My nos was not on I was just ticking over, heard a cracking noise and switched off when I restarted it started to squeal, took head off , knackered cams . Took sump off and full of trinkets Edited June 22, 2020 by SFC Quote Link to comment
