Long legged YZ100
« on: April 11, 2015, 11:06:41 PM »
Good morning Gentlemen, at least it is morning where I live...

I did some mockup work this morning and I wanted to show off the results.

The front end is YZ125G 36mm fork tubes.  The rear has Dave R's extension kit installed.  I have the YZ125 triples mocked up using the free ball bearings and races from the original YZ100 triple.  It all fits together save for the bottom seal.  Not sure what or where I am going to go with this.  I consider this to be exploratory surgery.

Please excuse the mess in the background.

Here is a better shot side on...  It looks like a "big" bike.

Lookin nice with the fork boots and fender! 

Did you use the full spacer and use a torch to bend the frame tube?

I got fresh swing arm bearings in my 125 and am figuring out how much of the jack-up kit to use (thinking only 1 and 1/8").  Figuring out how much plastic spacer to cut and how big a bump stop to use.  I've still got some tinkering and thinking to do.

Are you happy using the full jack-up length?  I'm having the shock hit the airbox, as well as the frame when I use the full length. 

Unfortunately, I'm also missing a ring locator pin, so this is going to slow the project down.  Have you decided upon an engine for yours, yet?

Really, can you post too many pictures?

Getting back to this.

Been a long time.  I tore this down and painted the frame and swingarm and have started re-assembly.  I think I have managed to come to decent solution for a properly sprung rear shock.  This is fitted up with a 1981 MX175 ($25 on eBay) shock that I have installed Dave Riley's extension kit on.  With the extension installed the shock is about 1" longer than the stock YZ100.  It fits in the frame without hitting the backbone tube or the airbox.  When I sit on it doesn't feel like it has been sprung for 125lb kid.

Just trying to decide if I'll use the stock tank or go with the IT125 tank.

Nice work Kirk.

Can't wait to see it in action.

Cheers,
