This is an incredibly cool 1982 ATC 250R.  Someone put a lot of money into this back in the day.  Unfortunately the original builder of this amazing machine is not available to give all of the information on this build, so I am going off what the second owner was able to tell me.  THE ENGINE:  Hondaline 300R that has been custom sleeved for a Yamaha YZ 465 piston and port matched.  The actual CC's comes out to around 368.  This runs on methanol and uses a custom Mikuni 41mm carb with a powerjet to deliver fuel.  This also has a VERY rare lockout clutch with a custom cover that has been extended to clear the lockout.  This also has a custom aluminum intake manifold.  The previous owner claimed the piston was fresh with very low use.  Engine runs PERFECT and typically starts first kick every time and SCREAMS!!!THE FRAME:  I was told by the previous owner that this is a Nicholson frame, however that has been questioned.  I was also told that it could possibly be an "MTC" frame, as Nicholson and MTC were really the only companies that made an aftermaket frame for the air cooled bikes.  Regardless, the frame is a work of art, and incredibly rare.  As it is aftermarket, it did not come with a title.OTHER HIGHLIGHTS:  -The front end has been converted to the 83/84 forks and steerer.  -Custom plus 2" chrome swingarm (not sure who made it). -Chromed Dura Blue plus 2" (each side) axle-Works rear shock (will need to be rebuilt)-Custom built side pipe/silencerTHE BAD:  Rear shock needs to be rebuilt, needs new seat cover, rear fender is junk, front fender is oxidized.All in all this is an incredibly cool and rare air fooler.  Very neat piece of history here that needs to be preserved.  I would keep it if I did not have crippling medical bills =)
