...sorry that Im a bit slower to post but I have been very busy with my free time.
for ex.: I had a problem with a rebuild of the gearbox of one of the British motorcycles that I got. The 4th gear jump out, so I did all the tear down again (foot rest, pipes, primary cover, clutch, covers, sprocket and the complete gearbox) to see what goes wrong...
I have been making fins; here s a fiberglass quad set for the 4wfs.
