To make a long story short.....too late. Unfortunately, it is a long story. My motor seems to be working fine. It still does not have the power it once had, but as you saw from my previous post, I have great compression. My buddy recently picked up a motor off of a friend. This thing had almost every gasket blown on it. I was actually excited because it gave me an excuse to tear open one of these motors. After taking the whole thing apart, I cleaned it up, made some new gaskets, swapped out just his motor with mine, I used my carb, exhaust, etc. Although, when I tried to fire it up, no go! The clutch was slipping like crazy. So, I learned how to adjust the clutch, pretty easy to do know that I have actually done it. Gave it another attempt, The motor fired up after a few tries. His motor has the power that mine used to have. Tested his compression and it was identical to mine, right around 115 psi. This I do not get. Same motor same compression, but mine is now lacking. If anyone out there has any thoughts on why this would be, please fill me in or give your opinion. I used his motor on my bike for about 2 weeks...good times, this sucker worked beautifully. I put my motor back on my bike and I can definately notice a difference. Back to my issues, I still have a fuel leak, believe it or not, I am begining to think that it is not the fuel line now. But to answer your question regarding fuel line size, I am using a I.D. 3/16 vinyl tubing, it is a very snug fit. I do not have very much free time to work on my engine but it does consume me when I do. I have been putting "Ebonita" together again and have encountered some fun issues.

The original owner had posted pics on his site showing the chain going from the engine to the jackshaft having too much slack in it. I had the same problem. Removing one more link would make it impossible to attach the chain. So, I left the chain too loose, had everything installed, hopped on the bike to take it for a test run. Popped the clutch and the bike just came to a stop. Hmmm....that's weird I thought. It wouldn't roll no mater what I did. So I carried it back to my garage. pulled the cover off the engine sprocket and the chain was all bound up in there. So i got it un-stuck and tried again. Would you believe it, it did the exact same thing again...shoots! So, I figued out that the chain is way too loose and needs to be significantly tighter. There is no room for an idler wheel, so I removed another link and wouldn't you know it....too short. I think that I found a way too make it work. I am going to be forced to use the alternative method installation plate. I will attach a picture when I get a chance. I think it will work, but I won't know until I pick up a few parts at the hardware store tonight. I hope this update is what you are looking for. I am going to have to trouble shoot my carb a little more. If I find the problem, I will post the results.
