lineaway Posted April 11, 2014 Report Share Posted April 11, 2014 So what is wrong with the transmission as they were pretty solid. Worst thing I ever saw was a bashed case bent so far as not to let the shift drum turn. Quote Link to comment Share on other sites More sharing options...

jonboy883 Posted April 11, 2014 Report Share Posted April 11, 2014 (edited) There was a fella that used to advertise in the back of Trials and Motorcross News, as The Rotax Man, but I can't remember or find his phone number. Anyone else have it, because he could get anything for a Rotax engine.....and that is what the Aprillia is. Anyone else help with the number.

Two things to look out for. The second sump bolt is the detent for the shift drum which could be missing or messed with. Also since the shift shaft runs through the starter shaft they would bind up from rust and corrosion. Quote Link to comment Share on other sites More sharing options...
b40rt Posted April 11, 2014 Report Share Posted April 11, 2014 Peter Knight has retired, unfortunately, he was fantastic. Gearboxes as said are very reliable generally. Only seen one post ever on here with a problem, and he was a plonker. So as much info as possible and we will try and help. 1 Quote Link to comment Share on other sites More sharing options...

noizy Posted October 1, 2014 Report Share Posted October 1, 2014 Hello people, I have just registered to this site as I have also just purchased an old Aprilia 280 climber 1991 I think. I have a question. I have good spark and a clean carb with good compression but will not fire or even fart. I have taken out the rotary valve to find it has no marks for timing. I have looked on youtube for rotax rotary valve timing and only managed to find the Rotax twin cylinder engine set up. It states 147 degrees from the leading edge of the inlet port. Fine, that is a good starting point. My rotary valve has a shaped edge and a straight edge. Which edge would be leading, i.e. to open the port? Also is the port supposed to be egg shaped, or has someone tried to flow the port? Regards. Quote Link to comment Share on other sites More sharing options...
