1986 Aprilia TX 311 m

Featured Replies

Hi I am new to this, Last time I rode a trails bike was 1972,  I found a nice old Aprilia 311 in good shape.  Just a few questions to start,  What fuel mix should I run in the bike?   Is there anyplace in the Us that has any parts?  I started it on a 50 to 1 mix seemed to run ritch, but everything seemed fine. There is also a engine compression adjustment device on the front of the engine, I have never seen one?   Thanks for the help, Mark 

Rotax engine, 50:1 semi synthetic. They do collect oil and need cleaned out. 

Interested to see a picture of the compression device.
