The other issue I referred to... The muffler bracket had a bolt back out. It backed out till it was rubbing the tire and wheel. No big deal right? Yeah, right. My luck doesn't work that way. I got the bracket rigged up to work till I can get a new side case, but one of the exhaust studs has snapped. I got the stud out with needle nose vice grips. Thanks to the lovely design of the engine mount though, I can't get another one started. I guess I'm pulling the engine.

If there is some sort of bad luck scootering award, can I get a nomination?

If it weren't for bad luck, you'd have no luck at all.

Since I had to pull the motor to do the stud, I figured I might as well see what happens when a little more compression is added. I swapped over to the 72cc head and 50cc carb setup. If it doesn't blow up, maybe I will get better than 50MPG too. I'm slow and lazy today (lack of sleep), so the engine is still waiting to go back in.

You know, looking at that setup, do you think it would be stronger if there were two bolts in the center so it can't move in a scissor like manner?
Maybe just weld the two pieces together?

I can't weld aluminum, so I might put 2 bolts in there once I get a new cover. Good idea.
I never have got the engine back in. I ended up deciding to put the stock cam back in. It hasn't really been revving that high so I figured I'd try and pick up more low end power. Maybe needing to rev a little less will keep the gas mileage up as well.

Make a new bracket out of steel stock and weld that. I think that the scissor action is what did that case in due to the pipe flexing. The engine got ahead of the muffler and the bracket scissored causing more stress on the upper mount. As for the stock cam, what have you got to lose? Cam installation only takes 1/2 hour even if you get side-tracked a little. Might just be what the doctor ordered

I might do a new bracket, but it may not be that hard just to mod this one like you suggested. I didn't touch the scoot yesterday. I decided it's best to wait on the new cover and do it right. It'll be easier to do a bracket with the whole cover intact too.

How do they get those 139's running so strong at the drags? If they all ran like that,I'd have to have one!!

Even the SunL will move pretty well to 30-35MPH with me on it. Put a light rider on it and it will prob pull pretty well to 40. I think after that the lack of horsepower compared to the 2Ts starts showing. Notice that Roberts 2t not running that great was pulling over 50MPH traps. The 85cc nitrous 4T that won that class did 47MPH. I'm not taking anything away from J and Skipp either... that's pretty sweet for the 139QMB and I haven't hit that speed in mayn miles, let alone the 1/8.
