I have long drag pipes on my bike, I know I need to rejet them. I've looked up on what the steps are and what pieces I should buy. But I can't find anywhere that tells me what sizes I need to put where. Can anyone provide some insight?

 

I think most run 45/180 for the jet sizes on a 1200.

you can go to jpcyles and order several sizes between 160 and 180 for the main jet and a 45 for the low jet...your best bet is to pull the jets you have now and look at the numbers on them...

I would get one of these if you don't already have one
