Picked up a Harrison Wildcat on craigslist yesterday. Doing some of the standard mods that make it a more viable and structurally sound bike. It already had the jackshaft plates (factory installed.) But it did not have the angle iron modification. Also I always weld a kick stand mount bracket on this frame too. But the biggie that really needs done (at least for my fat butt) is a springer front end.
To do this you'll need some parts:
(4) spring cups.
(2) springs (both available from https://www.OldMiniBikes.com/nos-front-fork-springs-and-cups-kit.html )
And the biggie...
(2) 11/16" diameter 12" long solid steel rods.
Now the 11/16" diameter (.6875") rod is kind of tricky to get. It's obviously not a common size. But that's what works. You may have to do some hunting to find it. Or buy 3/4" (.75") rod and turn it on a lathe.
Note you could certainly adapt this spring concept to other makes/models of mini bikes.
The key to this modification is doing the cuts in the right places. Below the picture shows the general cut idea. This modification on the Harrision adds about 2" to the overall fork length. This makes the bike ride better! It increase the rake slightly, increases ground clearance a bit, and levels out the motor plate to the ground. Again makes for a better ride!
