looks like my OS12TR might be biting the dust finally. i stripped the pinch bolt and cant find a replacement, or get the thermal insulator out without mangling it to replace the bolt anyway. might try to jbweld my carb in but probably not a great solution..
I just race in parking lots. maybe 80-100ft straight with technical infield. my 12tr was enough to keep up on a track this size but what could i get that isnt super expensive as a replacement? i see a maxpower for sale here used. how would the rb jr engine perform?
