Default Re: Bicycle Engine

Met a guy today with a very interesting bike. Grubee GT2 (or GT2-A, not sure of the difference), Arrow motor, Sturmey front drum, Manic hub adapter, sbp expansion pipe, etc. Said he's had nothing but problems with it. Most commonly broken piston rings, but other things as well. Said he's done throwing money at it, and he's upgrading to a ktm clone. It doesn't surprise me at all.
