1981 Street Tracker:
Here are some pictures of my recently completed xs650 street tracker. Your site has given me a lot of inspiration so I thought I might return the favor. I wanted it to be the nicest AHRMA legal and street legal street tracker on the planet. It started as a 1981 $40.00 junkyard bike with weeds and green mold growing on everything. It was stripped and the frame lightened and powder coated and a 1986 Yamaha Radian swing arm added. I installed a Barnes quick change rear wheel with a 19" wm6 excel rim and Buchannan stainless spokes running a 520 chain. The stock front hub was powder coated and laced to a 19" wm3 Excel rim with stainless Buchannan spokes to match the rear. Goodyear/ Dunlop Eagle DTII dirt track tires in CD5 compound were used front and rear. The engine was rebuilt by me using a Shell Thuet 81mm 750 big bore kit, #1 cam and his performance valve springs. The 2mm oversize intake and exhaust valves and all porting and machine work were done by Chris Schumann at Portland engine re-builders. The cases and covers are all painted or powder coated and hide new performance clutch plates and springs. 36mm Mikunis with K&N high flow filters handle the fuel supply and are opened with a Motion Pro throttle. The ceramic coated mile pipes are from Jemco.
I also added a right side shift (I kept the left too) and installed a Boyer electronic ignition and a custom modified (by me) 20 amp permanent magnet alternator (no brushes) out of a John Deere tractor so it will start even with a dead battery! I modified the stock rear brake pedal to activate a custom mounted Suzuki GSXR 750 rear master cylinder with remote reservoir, painted caliper and stainless braided lines from HEL. The single gauge is a ProCycle electronic tachometer in a custom turned aluminum mount so there is no cable to spoil the dirt tracker look. Front forks and painted front caliper are stock but the lower legs were stripped of their mounts (except for the right caliper mount) and a light weight drilled disc added along with a steering dampener. The two Halogen headlights are mounted in a custom rubber dampened mount to hide all wiring and to house the switches for lights and high beam. The tail/brake lights are custom high intensity red LEDs mounted in the custom seat support pan. The seat and tank are fiberglass for a XR750 Harley with the seat assembly being mounted using quick release DZUS fasteners. Paint was done by my father using epoxy base and clear coat. I laid out the graphics in the traditional Yamaha track pattern (it is Yamahas 50th anniversary after all).
Finally I used "the last set of yellowspring Redwing rear shocks on the planet" and tapered steering head bearings from Omars. This project has taken most of a year but has also been more fun than I could have ever imagined. I think it is the nicest one on the planet but then again I may be a bit biased!
Thanks for a great site
