z1wiz told me about this bike when it became available. This will be a long term project.
I do have the engine for the bike also, but it's put away for now.
I started looking for build ideas.

I really paid attention to testa's bike kzrider.com/forum/11-projects/340793-tes...ter-build?start=1660 but thinking of using piggyback shocks instead of the mono shock setup. I'm also wanting the correct geometry when the bike is finished

I'm just mocking things up for now, but I have ground clearance concerns. I found this on the internet. xa.yimg.com/kq/groups/151519/1311856614/...Pictures+-+Rossi.pdf
Has anyone used for extenders for a streetfighter conversion?

I was told of a couple of places to maybe get fork extensions.
I sent the first place an e-mail already, to see if it will work for what I need.

This is the second place I was told about.

I would plan on about 4" of travel in the rear. Not sure your current mock up will support that. You may have trouble with piggy backs clearing the over brace, unless you cantilever them out a bit.

Yes I know it's too low at this time, but I ran out of front fork height on this mock up.
I'm not 100% sure what I'm going to do about the shocks at this time, but I'd like piggy backs if I can figure out a way of doing it without removing the overbrace.
Good news is, Tom from cycle one off e-mailed me back and said his fork extensions would work perfect for this type of project.
Now I need to get the triple tree mods and swingarm bushings done, so I can figure out how long of fork extensions I might need.

For reference, my frame is 9" from the ground with a 1" drop upper triple. Header pipe is about 6" off the ground. Compared to my other bikes that's a ton of clearance and I've never hit anything. Biggest issue is the width of the motor, but I don't plan on road racing so hopefully I won't scrape the ground in normally cornering.

Those fork leg extensions are a neat idea, if they fit tight to the leg. The One Off link looks like maybe they clamp to the leg? Good luck with your project.

I like the height of my 1978 LTD1000, so I measured the clearance on it.
The frame has 7 1/4 inches clearance and my Kerker has 4 1/4 inches clearance.


I then transferred these measurements to my mock up.
When I did this, my front forks dropped 1 inch. If I left it at this height it looks like a 1 inch fork extension would work. I'll know more after I get the triple tree mods done and swingarm bushing made. I think I'm close on my measurements, but I won't know for sure till I have a rolling chassis.

Did some more work to my mockup last weekend. I now need to set the height again.

If I can ever get a free space on my work table, I'm going to get this running.
That damn turbo KZ has been a thorn in my side and has kept this bike off my operating table for too long.

Mockup is set at the correct height now.
z1wiz did a stem swap to my triple trees over the winter and I just ordered 1'' fork extension from cycle one off.

Next I need to have some swingarms bushings made.

My wife was gone this week, so I worked on some of my bikes and finished mocking up the suspension on this one.
I set the rear suspension up exactly like a GSXR and added a set of one off cycle fork extensions to level it out. www.cycleoneoff.com/Photo_Album.html#
I ordered a set of 1 inch extensions, but I think they sent me 2 inch extensions by mistake.
I'm glad they did. It worked perfect to level out the bike.
I'm very happy on how it is turning out so far.

I ended up with 8 inches of clearance under the frame rails, 5.5 for travel under the duck bill and 35.5 to the top of the riders seat.
