The carb orginaly bought for the bike was a stock GN250 one, yet it was quite big and bulky and didnt do much for power exhertion. To Mackenzie's great luck and fortune, Luke found in his Tardis of a shed an old Mikuni TMX38 flatside carb from a Husqvarna CR 250. This would not only look better, fit better, but also give a greater power output.
Much better looking
Once ultrasonic cleaned, new jets and a 2" thick round K&N air filter fitted, will look and run a treat!
