Is it possible to make the RC 390 GP Shift on the stock rearsets? Has anyone tried it yet?
GP Shift
- Thread starter Chris RC390
- Start date
I looked pretty hard several times. I'm not saying it can't be done but not easily like some other bikes. The easiest way to do would be a shifter right on the shift shaft, will make it GP. Get rid of stock shifter and linkage and put shifter right on shaft like a Duc, will do the trick. No shifter will lend itself easy spline/offset wise though. "I" would buy proper rear sets.

I know I saw a post somewhere about someone running GP shift. I most definitely don't like the feel of the direct lever. I don't know why that is, but tried it twice on two different ducs, I'll need to look at this closer as well.

I just flipped the shift arm upside down. Still haven't got it exactly where I want it though. The manual says it should have a 75 degree angle, not sure if I'm there.

Ive ordered a shaft conversion bracket / peg thingy off ebay , its for a ninja 250 but i should be able to make it fit if the splines are different .

It can be done without any add-ons. I tried posting yesterday in this thread w/pics but I guess a mod has not yet approved the post.

No I didn't remove the sprocket cover but it can get in the way if the shift lever has to be adjusted. The cover is plastic and can be easily modified(cut) to allow the shift arm to be adjusted infinitely.

Just flipped the lever arm as Ash suggested , its near vertical . Close to the sprocket cover but it does clear and wont interfere with gear changes . Was supposed to be on track today but have a few little bits to sort out so will go up in 3 or 4 weeks .
Track only so i wont be able to test it out untill then !!!!!!

plus Rossi, Schwantz, and me! (of course our girls all GP)
I think I'd just shave a bit from the bottom of the sprocket cover? I'll try it later this AM.

I just flipped mine as well. I did extend the rod to allow clearance...no binding and it doesn't hit the sprocket cover.

Rossi uses street shift? Bugger copied me.
I used the thingy off ebay at the track worked perfectly.

Be careful when you're setting this up to ensure the heim joint on the shift lever does not make contact with your rearset. Mine was very close, and slightly impeding my ability to shift correctly. The may have contributed somewhat to my transmission jumping out of gear last race weekend.
