Raptor carburetor rejetting, and effects
#1
By looking at the carbs on the Raptor, and the lack of room to work on them, it appears to be quite a task to rejet. Has anyone done this, and how difficult is it? Please tell us the routine. Did the bike benefit from richer jetting? What sizes of jets did you use? Also...has anyone been able to get a factory service manual? Tell me who has them!!

The manual may be hard to come by for the first year. I would try to sweet talk your dealer into purchasing one. If they won't do it, buy one of the mechanics lunch and maybe he will let you photocopy the parts you really need. Heck, take it to one of the copier stores and they can make the whole thing for you.
I think the non-factory manuals (like chiltons) won't come out for a year or two. I could be wrong, but I think there is a copywright infringement or something like that which keeps the new machine owners without a manual for the first year or so. When I bought my 96 KX500, I had to get a manual for a 94. Same kind of thing when I got my 98 Banshee.

High tech carbs? Was that suppose to be funny? They are BSR's...
Don't worry, I'm sure there will be aftermarket carbs for it.
As for the jetting, one carb is suppose to be jetted richer than the other. (one size larger I believe) I don't know which one. I would think you would want to jet both carbs, not one. Otherwise it looks to me like you would have a real rich fuel/air mixture coming in and a real lean fuel/air mixture. That sounds like a good way to cause internal damage to me.
Does anyone know if the richer jetted carb is on the 2 valves or the 1?

From what I have read...the richer carb does control 2 out of 3 intake valves. I have'nt taken the time to check the carbs and how the butterflies open in relation to the amount of throttle applied (very tight fit and it looked like a big job + I did'nt want to get caught tinkering with it just yet!). So does both carbs open at the same time, or does the other carb operate on engine vacuum (sorta like a vacuum secondary auto carb)? Thanks!
