Hi,
I know Banshees are notorious for their tranny's and shifting. I have owned a few and I don't recall having this problem as much as with this one.
When I am out riding in the desert or dunes and I am dragging or otherwise shifting through the gears under full power, I have the following problem. This occurs when booth hill shooting or flat surface (ie sand drags).
I start in 2nd, power band kicks in, quick shift to 3rd, no problem. Quickly loaded back up , pull in clutch and go to shift to 4th. Damn it! The shift lever lifts all the way up through the motion (or so it seems) but never disengages 3rd and engages 4th. Ok, pin it again for a second and try again. Same thing. Let a little off so the engine is being turned by the wheels a little, pull in clutch and shifts smoothly.
The same thing occurs for 4th, 5th and 6th. I have no problem hitting those gears when I am not doing a quick drag style shift. If I am just cruising and I do a non-rushed shift, where I just casually let off the gas, pull clutch, shift, and release clutch there is no problem. It really seems like it has the problem when I am hitting full throttle and do a quick shift motion (using clutch and letting off gas, just doing the motion quickly).
The best way to describe it is when your bike is stationary (usually off), and you are trying to move through more than one gear. Where the first gear change is fine, but then the next gear change doesn't disengage/enagage, the shifter just moves up or down with no resistance, and you have to rock the bike to get it to shift again.
Any ideas on what this could be? I am going to troubleshoot it this weekend some more to see if it could be some simple stupid issue with the externals:
not using boots, just shoes
watching for shift level flex
etc
However, I am hoping this is a issue blatant enough for you repair gurus to point me in the right direction. I bought a shift-pro (yes I know some hate it and some love it), and I am going to try that as well just to see if it helps. I don't think it is clutch related. I've kind of ruled that out since 1 - 3 seem to USUALLY be fine. I have no other tranny problems I notice (noise, hard shifting, pop up of gear, grinding, etc). My problem seems to be isolated to quick shifting while the engine is wound up.
Oh, and on an unrelated topic for you guys with a +4 swingarm, what length chain (or even model #) do you need. Any good sites to pick one up at a good price? What about the brake line?
Thanks!!!!
