MOPED ARMY

No I havn't. I'll try that first when I put the bike back together. I took everything off the frame yesterday, gonna clean and paint it, and then I'll switch over to tranny fluid. Last time I did an oil change I switched to tranny and all it could do was roll at a few miles/hour and dump a bunch of smoke out the exhaust, so I switched to engine oil. When I emptied what was inside it the first time, the oil was an extreme shade of shit brown, so we figured the bike took engine oil instead of tranny fluid, unless of course it was really really old tranny fluid and lost all that pink. The moped manual used the word "oil" to describe transmission lubrication rather than "fluid" so we just assumed tranny fluid just wasn't what it needed. Any other ideas?

Well since I have the exhaust off I'll clean it and if I don't get a new one I plan on painting it with some high temp black. But how would I clean out the inside?

how do you increase your compression? remove head gasket? milling the head down is probably out of the question for this noob.

Haha. He's right. I can manage taking out the head gasket, but do you have any other suggestions on increasing that compression, Bitter?

get some sheets of emory cloth, both coarse and smooth, then some 100 grit, 150, and 200 grit sandpaper. slide the head back and forth and in figure 8's for an hour each night for a week on the coarse, then make it smooth with the other grits of paper. you'll have a little more compression and a very strong arm. this is of course assuming that your head is the type that does not have a recess that a lip on the cylinder fits into. if thats the case then its a little more involved.

eh, moped compression is generally so low that theres alot of space between the plug and piston. you have to sand for a long long long time to take off enough to get into trouble. i've done it with tecumseh and BS heads before, you need a machine to take off enough to do any damage really, or sand it like a lunatic! he can use a little spray paint to check flatness tho, dust the head with spraypaint and then sand it against a flat surface. that'll show any high and low spots. the goal when done is to have it flat and to have taken a little off.

if he wants to get into it hardcore then he needs to pour liquid parafin into the engine at TDC, install the plug, let it cool, remove the plug, then pop the head off. that'lll give him a decent idea of his claarences and allow for an easy measurement of the plug to piston gap.

those morini engines typically have a huge head gasket, i would remove that, its about the width of two credit cards

drilling out the manifold helps, its usually 12mm if i remember right,

drilling some serious holes in the air box and up jetting helps

and a pipe is going to make a big difference, get a bullet or something on there and it should be well into the mid 30's

yeah polini makes one, and its pretty terrible, and hard to come by

i would personably try and make something better fit

you have no idea how bad i want to man. nick g emailed me with details and i emailed him back. he never responded whats the final deal? I kiiiinda can miss classes on friday, but no such luck on monday. if we're not defnitely be back by sunday night, theres no chance. whats the final cost of ish? he mentioned a uhaul. what do we need that for? if you can get some details i can see what i can do.
