What did you guys use for your gear shift lever connected to to the engine? Stock or something else. I have the cable setup and the short stock lever on the engine side seems a little too short and requires a lot of force to move, was thinking of going longer but not sure where to get one.

Was looking at something like this but not sure of the bore size.

You may have trouble determining what normal shifters have the correct spline and diameter.

I don't know what it looks like, but I'd consider welding a steel strip to the original arm for more leverage, then drill the end for a small, studed spherical on a 1/2" tube horizontal link.

I'm going to be using something like this


Which is basically exactly what ^ said, but with a visual aid

The above might be a little difficult to implement considering the busa gear selection shaft runs longitudinally.

Unless you want to make a bellcrank you'll have to get a push/pull style cable and snake it around to the side.

That's a good point.

Here is an 08 busa shift linkage. I wouldn't alter the bracket at all. You can adjust the throw and effort on the hand shifter end.

I used an old Japanese motorcycle at the wheel brake lever that was used on the old shoe type brakes. The spline and diameter is the same as the spline on my GSXR1000 shift shaft on the transmission.

I have a paddle shifter using a '91 Mazda automatic push-pull cable as the link between the paddle shifter and the modified brake lever. There are some pictures on my website showing how I mounted the cable on the steering column and with the original brackets from the car used at the transmission end of the cable.

Unfortunately the brake arm is mostly hidden behind an oil line in the picture but it does fit on the shaft like it was made for it. I had to shorten the length of the lever to get the ratio of paddle movement vs the angular movement the brake arm has to move to do the up/down shift.

Ended up making my own from sheet metal. Now that I look at the diagram above I might have been able to use the standard setup if I had actually looked at it. If mine gives trouble I have another solution to fall back on, thanks





This is during my test fit, I have since taken it off cleaned it up and painted it. At a high level it works.

I don't want to get anyone's hopes up, but I have had an '04 Kawi ZX6R shifter and an 88 Yamaha YSR50 shifter on my '75 Honda CB360. I don't think the shifter spline changes a whole lot. The ZX6R was a linkage shifter, it might work well in your application.

Simple... most sport bikes levers are aluminum while dirt bikes are steel. I picked up a yamaha dirt bike shifter (pretty much all the models have the same diameter and splines), cut it up and welded on my own arm to the steel splined area.

This works the same for Honda as we did it with our FSAE car.
