1990 Yamaha YZ490A

The bike upon at arrival, after finding it on a craigslist add. The pipe was bent pretty bad in front of the frame and cylinder The oriniginal Bridgestone M22 & M23 tires were still on the bike but dry rotted really bad. The original chain was rusted really bad from sitting outside for years The tear down begins The rims were starting to corrode and were beyond repair The bike has absolutely no compression. A big chunk of piston was gone but was not in the motor, the piston looked like someone ran the motor with no oil in the fuel The frame back from thepowder coaters Excel rims laced with Buchanan stainless spokes to powder coated hubs, all this work was done by Pro-Form racing in Ontario California The rebuild begins The cylinder at Tom Morgan Racing so that Tom can work his magic Almost there, just installed the Pro-Form racing pipe & silencer All done and ready to race Farleigh Castle VMXdN 2013
