does anyone know the part number for the circular plastic part the cables hook up to in the starter/kill switch

Dennis Kirk sells generic motion pro throttle tubes for the big four jap bikes. I bought the Yamaha R6 tube and put on my F2, it allows full range from idle to full throttle without regrabbing the grip. Works great on the track. Had to grind with the dremel a little to make it work but I think it only cost $10 or so. If you hold both tubes (stock honda and stock yamaha) up to your face like binoculars you can see where it needs grinded.

 

awesome do you know where i could buy one?

 

did a lilttle research the r6 uses a 1/6th turn tube instead of a 1/4 turn on the f2 but after looking over other threads the cable for the f2 wont reach a r6 grip without modification was that the same case with your f4i? Also Denniskirk.com has a stunt throttle tube http://www.denniskirk.com/jsp/produc...fCatId=&mmyId= What exactly is that?

 

I have a F2 not f4i. The cable did reach just fine. Only had to dremel a little like I said. I think a stunt throttle is the complete oppisite. Like maybe 1/2 turn of something like that. I think its like that so more precise throttle control during wheelies and stuff. But I am not sure. I also bought a r6 throttle at the Yamaha dealership for my 08 cbr 1000rr. $22 included grip 2 years ago.

 

wait so what bike did you change the throttle pole on?

 

Both bikes. The Dennis Kirk r6 tube went on the old F2 and the dealership r6 tube with grip went on the 08 1k.

 

I just reread up above, the f2 cable would not reach at first. I had to go in to the bike to get more slack. Remove tank, remove airbox, then adjust the cables at the carbs. Got all the slack I needed. After install adjust slack at the handle bars to spec.
