Just wondering what size jets and needle settings everybody uses on the micron exhaust system?? I don't really want to pay £380 to have a dyno jet kit fitted and whilst my bikes apart I'm going to balance the carbs and would like to finally jet the carbs to suit the full micron exhaust system I have fitted. Standard air filter.
1999 L9 model
Cheers

Re: full micron exhaust system jetting
Almost impossible to give you a definitive answer as every bike will fuel slightly differently. I would guesstimate 100-105 mains, if you use a dynojet kit you might find that your mains will be different to this as the needles are richer in the dynojet kit.

Re: full micron exhaust system jetting
The bloke who works on my 1992 zxr400 (32mm carbs/ full micron system)said, i think, that i needed 120 jets.
I dont really know what the means, might help though.

Re: full micron exhaust system jetting
Alright cheers guys, to be honest I've not really noticed any difference to when I had the standard system with just an endcan fitted, only really a flat spot around 5K, and it's always ran abit lumpy around 4K even before fitting the system, so guess I'll just have the carbs balanced and go from there, I don't get any signs of it running lean on wide open throttle so I'm guessing if anything needs adjusting it'll be the needles.
