Pics of the new YZ85 pipe.. To fit this bad boy i cut off the flange and 2 inches of head pipe, i the made 6 pie cuts on the end of the pipe and used a torch to smoothly close all the "fingers". This made the head pipe small enough to put on a china girl flange. Then i cut the pipe in half at one of the bends, rotated the head pip 90 degrees and welded the chamber back to it. Took about 2 hours, for $35 dollars you cant get a better pipe! I sort of got lazy after finishing and slapped a 50cc four stroke muffler on the end with bailing wore so its not so loud. Next ill make myself a muffler. To be fair I can't give it an honest test. My clutch is suffering, it's slipping really badly and not putting the power down. I tried two different used clutches to no avail, I even pulled out all the glazed pucks and roughed them up on some concrete and that helped marginally. New pucks will be here later today and I'll replace them all. Until then I can't really go over 1/3 throttle until I'm over 30 because the clutch will just go right back to slipping.
