1998 cr80R pro circuit exhaust, Boyesen Pro Series reeds. Modified Yamaha intake manifold to except a 34mm race carb with power jet for alcohol. Big aftermarket air cleaner. This bike has been converted to run on methanol and bean oil. Very fast!!! Everything works. Bike runs excellent. New rear disk and pads and wheel bearings and seals. The bike can be converted back to stock. Comes with original carb and intake. No low ballers. I can sell this bike for $1000 stock. Comes with 2 gallons of premixed methanol so bring a gas can. In one of the pics you can see the diff between the stock carb and race carb..
