Some may recall I "found" a chro/moly tracker frame last fall.
Weighs 17 pounds compared to a stock frame's 49 pounds but it is "a work in progress"
I got a mock up engine stuck together to see what this is going to take.... this is going to stretch my talents and then some. Just about everything needs to be "built special" So this is the progress, issues, and results of a first mock up. I hacked up a stock swing arm to fit around the center tube to see how it and the engine will fit in there.
I put the engine on the lower and upper back mounts and found my first issues. It is VERY tight to the swing arm pivot I had to cut away the tab quite a bit to get it in. Then I went to mount up a set of carbs. No joy, I could not get them in, they were hitting the back bone. I grabbed an early set of 38s and they made it in but just.
Then I tried a set of Kerkers I have which are light and tuck in very tightly. They were hitting the front tube and would not align correctly. Then the light bulb came on. There is no lower mount yet and no bracket between the front engine and frame mounts. I pulled the top mount which let the engine swing forward about 10 degrees. AHA that was it.
I will need to fab longer top back brackets. the front frame - engine mounts now line up better, the exhaust clears the frame and there is more room between the case and the swing arm.
That is a Knight tank and seat. There will be some fitting issues but nothing major, the engine swinging forward allowed room for the petcocks also.
Next is the Steering neck. Oh boy, the race bores are 50mm top and bottom. which fit no roller bearing I could find. Stockers are 48mm I may have found a fleabay fix but will have to wait for it to get here. The neck is short like the early triples. It has a cool internal fork stop welded in but it hits the large XS stem tube.
So I guess that has to go. Next up is forks, I mounted up set of 76 forks I had and was scratching my head cause the bike was sitting up so high. Oops they have 4" over tubes. So I am thinking either a set of XS750 forks with dual disks or a set of Late model XS650 forks with a mikes rotor and cartridge emulators. I scored a set of tapered bars and risers and like how those look. They are jsut sitting on a triple on top of the forks on the bike
Wire wheels. If I keep the kirker it looks like I will have to section out a few inches from the middle cause this frame is shorter. I want to get to a reverse cone "dunstall look" type muffler. The swing arm will probably have to be a complete fab up, I am thinking that through now. Those shocks are junkers but I like the looks of the remote gas shocks.
Feel free to chime in with hints, tips, suggestions or
