    Come on, Ron, you have been around long enough to KNOW that the only place to get "carb kits" is from our own member, Robert Barr. Visit his site at cycleorings.com. All you need is the full o-ring kit, but be sure to also get the o-rings and stainless bolts for the intake boots. Total will be less than $25.

    Yes, you will need to re-jet. Stock main jets are 115. Depending on how well the pipe is baffled, I would suggest at least 125 mains, maybe up to 127.5 or 130, if the pipe is louder (less baffling). My son's 850 (which has since been sold) had 125 mains with the rather quiet pipe on it. Not sure of the manufacturer, suspicions are that it is a Jardine. I kept that pipe, will be putting it on my 850 before long.

    You might also need to raise the needles a bit, but you won't know for sure until you do some testing.
