GP handlebar control rod slop.

[Knowledge]

I agree with SB. I use splined rods and weld then at the end of the grip. The splined end onto the pulley and the weld at the other end eliminate the vast majority of the slop (the rod can stil twist along it's length if your gear change is particularly stiff, but it is neglible). Use nylon lined cable, but expect some stretch if fitted new. Be prepared to adjust them.

On top of the engine, fit NOS pivot and swivel (Madspeed had some Spanish NOS items) and fit new trunnions to the cables. Remove the gear change lever (the one that comes out of the gearbox) and cut off the lug on the top. Weld on an inverted (upside-down) M6 bolt* in it's place and use a nyloc to secure the tie rod instead of the old circlip. Make a new tie rod between the trunnion and the M6 bolt, ensuring that there is the minimum slack in the tie rod.

That's how to eliminate slop in your gear change.

PS: The splined Spanish wheels (ali) are as good as italian parts

* Some people use a stud instead of a bolt. I prefer a bolt as studs tend to be waisted in the middle, incuring some sloppiness. In fact, I prefer a bolt that is not threaded along it's full length.

If you cant get the early bits drill and tap to m5 and dont use the roll pins, the bush at the end can be held by drilling from the side and using a pop rivet. No pictures of that, but I have one to do in the morning so will take some so you can see what I am on about.Heres some of the gear change.

Thanks for all the replies. It's really just the handlebar slop I need to sort as the rest is new, or modded as suggested.If you get chance to post a pic Jason, I'd be gratefull.
Thanks again.

Neat work Shaun.

Despite the fact that Mark Watts has explained it to me on several occasions, I don't know how he managed to convert his bar-weight into a choke knob. Twist the end-weight and it turned the choke on.

Neat, but how did he do it?
