Main jet size? HELP!
Hi all. I have only had the bike a week but thought i would give it the once over. Its an import around L4 i think. I have just striped and cleaned the carbs nad ready to check all the settings when i noticed the main jet size varies. 1 & 4 are running on 88's while 2 & 3 are running 90's. Is this normal ? Would i benefit replacing them for 95's as i thought 95's are the standard uk bike size.

sometimes you can run the inner 2 cylinders richer to help keep them cool..
It sound like you have the smaller import carbs on your bike with jets sizes that small.
I would measure them carbs, and if they are 30mm, then get yourself some uk 32mm ones.

Bought some 32mm carbs of ebay. Replaced all the seals, reset the float heights fitted to bike and balanced them. definately a big improvement over the 30mm. Well happy!! Need to get a dynojet kit now and filter.
