We have been blessed with snow from the snow gods and it has been here since Tuesday. It will probably be un-ridable by Sunday though...
Anyway, when I ride my 1968 Olympic (Rotax 247) it gets really hot after about 10-15 minutes and then bogs mid range. It will idle fine and run full throttle no problem, but mid range there is a big bog. I noticed there is a small leak around the head, I was told it requires no head gasket to run (cast iron jug, aluminum head with bolts not studs). I have the jets turned out twice as much as the manual says they should be, and it till is giving me problems. I cleaned the carb, resealed the engine over the summer, and now its still giving me crap. Tried the spray on the seal and doesn't make any difference. Any ideas would go a long way in getting this running correctly.
