I am not really sure. I found a large exhaust leak at one of the connection points on my muffler and now have an issue with my auto locking hubs. Best I can figure there wasn't enough back pressure or something. When I took it out on the road it seemed to be better than last time I took it out. I think the motor just needs to be opened up and run on the road more but I'm afraid to run it too much until I get the Axle and Hubs fixed. When I go down the road it sounds like a card in a Bike tire and then a thud when I come to a stop.
I ordered a front axle rebuild kit from Marlin, conversion kit from Auto to Manual hubs, and New Aisin Hubs. Those parts should be in next week so I have another project before I can really get it out on the road.
I did put new non ethanol gas in it too and I think that helped.
I will keep everyone posted.
