Well, after 4 years of virtually no problems with my gasgas the transmission decided to self-destruct. Of all the bikes I have had over the years(mostly Honda and Yamaha) I have never seen damage like this. I am looking at replacing the main shaft,first,third,fourth,gears as well as the shift shaft and various bearings. There are some gears that are in questionable condition that may also need replacing. My problem is in Canada our GG distributor is very slow at shipping parts out. Is there any other transmission that is compatible?(TM?) Anyone else have this problem?
