Fair enough. That barrel/port design must have been common for some time.
Full race bike then, you got the whole thing? Even had the drillium treatment.

They're superficially similar to CR125s but there are next to no common parts. Porting, compression and everything is much wilder, no variable exhaust valve. Yeah, got the rest - it's my old race bike from YEARS ago. I ran out of money for racing in my very early 20s and it's followed me around various apartments (and continents!) over the years. The NF4 (pre-1995 bikes) are much trickier to get parts for but I've finally figured out a rod kit and piston for it so hopefully can go ahead and get it going. Just got the frame back from the weldor as it needed the footrest hangar welded up. I cracked one years ago lobbing it at the Mallory esses and it finally fell off altogether....
