MOPED ARMY

I cut the crank when I was in there. I did use a torch to split the cases, I could have damaged the seal while splitting the cases.

hey nick i had the same problem but sold my ped. My hunch is that the crank mayhave been cut to much allowing gas to blow by at the wrong time.

also, a failed seal because of the torch would require obvious, physical and visual malformation in order for it to leak like mad around the crank itself, it could be out of alignment on the outer diameter of the seal against the cases themself. not likely.

are you sure the jetting isnt just too far off so that it wont even run? timing? wet plug?

Mike, I cut the crank exactly to the spec provided by malossi for the kit.

Peter, the timing is fixed, and I set the point gap to the high end of the range in the manual so that I advanced the timing a little bit. The plug has been bone dry every time I checked it.

Jon, I cleaned out the emulsion tube with carb cleaner before I put the jet it, I could see fluid blasting out of the emulsion tube when I shot carb cleaner up through the jet hole.

We tried to use starter fluid, but the only bottle we had was one with a broken nozzel, that you had to push down with a screw driver. It never fired but I think that might be because we never got enough starter fluid in there. I'm gona buy a bottle and try that today

So I got it running today. First thing I bought a 24mm socket so that I could use a electric drill to turn the engine over. Once I did this I noticed that the spark was kind irregular. Like it would go in and out but once it got passed a certain RPM the spark would steady out.

I check the comp with the drill and I am getting 120, better than what I could get pedaling before. Still probably less that what it actually runs when it is going.

I upped my jet size to 68 and then used the drill to really get the RPM up. Then I dropped the decomp and it started right up. I messed with the electrical a bunch. Ends up the I can't read the resistance of the spark plug boot, its supposed to be 5k ohms, but it only reads open, so I swap out the boot with a different one and it evens out the spark a lot.

I still have two problems. I can't start the bike by pedaling or pushing because the belt slips and can't turn the engine enough to get it started. And once I get it started with the drill, it doesn't make enough wamps to variate. It just hangs out in the bottom gear. So I rip up to like 15 and then just hit a wall.

I stole some heaver weights out of my buddies Pollini variator and they helped a little.

So I ordered heavier weights and a new toothed belt from treats. Hope that is the end of it. Thanks for the help.

I've been considering the BOD, Next time i'm down there I might try it out to see how well it works.

Yeah, I put in the rear spring. With the weights that came with the malossi variator. I should be getting the 10g weights later this week.

You got the right belt dude? Shouldn't slip, but it's it's loose, it's not going to variate...
