LIsurfer_ Posted May 11, 2005 Report Posted May 11, 2005 I just picked up a used Trinity stage 4 single carb kit for my banshee. How can I tell if I have the 33 or 35 carb? Does the size matter when figuring my jetting? I want to get a good starting point from some of you for my set-up. I have a stock motor with FMF fatty pipes. Thanks for any help you can give................ Quote
RBD Posted May 11, 2005 Report Posted May 11, 2005 If the bore of the carb is concentric to outer body it is a 35 mm, if the bore is off set to the bottom of the body it is a 33 mm. Quote
LIsurfer_ Posted May 11, 2005 Author Report Posted May 11, 2005 ummm....thanks.....I think........can u put that in plain english for me......thx Quote
sheefreak Posted May 11, 2005 Report Posted May 11, 2005 Means the bore will be centered if it is a 35mm. If it is a 33, there will be more material on the top than the bottom of the bore. Quote
cam2 Posted May 11, 2005 Report Posted May 11, 2005 what are the letters and numbers stamped on the right side of the carb above the bowl? you should also see whether it's says PWK or PJ which will tell what type of keihin it is. if it's a 33mm PWK it will have S46 as the first three digits stamped on the carb, 70R if it's a 35mm PWK, and 67R if it's a 34mm PJ.

LIsurfer_ Posted May 11, 2005 Author Report Posted May 11, 2005 Great, from the pic (huge help) and the numbers it is the 35mm PWK....So what would be a good starting spot for my jetting with fattys and a k&n filter......stock otherwise....thx again guys Quote
Wallynut Posted May 11, 2005 Report Posted May 11, 2005 After all that, now you want jetting info Quote
Wallynut Posted May 11, 2005 Report Posted May 11, 2005 Start out around 190 and 48-50pilot, should open it up and see whats inside first, you might already have a good starting point already. Quote
LIsurfer_ Posted May 12, 2005 Author Report Posted May 12, 2005 thxfgor the info.......I definitely will open her up....but I think it came off of a big bore motor......at least now I have a good starting point......thx again guys....... long live the HQ.............. Quote
cgamla Posted May 15, 2005 Report Posted May 15, 2005 Hey just a note on this. I just played Jetting roulette for well lets just say longer than I ever should have only to find out that the float level in mine was set wrong also found out just how critical it was. It was so far off that I was running a 155 main and a 40 pilot and I was so friggin rich it was unreal. The casting line on the plastic float should rest parallel lto the carb body when you turn it upside down with the float bowl off. If its not gently bend the tab that presses the needle to the seat until it is. Quote
