that scooter has the factory carb with no mods , it never gave me any proformance trouble , it only has 2200 clicks .

what I did find the muffler mounts are welded to the side of the muffler and were broken for the last few hundred clicke and there was an exaust leak from where the muffler bracket broke from the body of the muffler .

I have never heard of a muffler leak causing a melt down, however a leak at the engine header pipe certainly will...

But you never know...

well guys , I got the head and cylinder off the scooter without dropping the engine out , any suggestions on getting the aluminum filings out of the lower case .

Just for the record this will be my first rebuild .

well I broke down and pulled the engine from the scooter and reassembled it , I know the head needs to be torked and I don't know what the tork specs are .

thanks guys

Torque the nuts down to 13-15 foot pounds. (some manuals are different)

Be sure to tighten the nuts down in two steps using a crisscross pattern. Be sure to lubricate the rocker arms before assembly.

I have my finders crossed for you John!!! Remember to put oil in it.. I have forgotten this step!!!!

[tvnacman]

I may have over torked it , is this a major problem ?

[tvnacman]

>>>I may have over torked it , is this a major problem ?

Maybe, did you use a torque wrench or guess?

[tvnacman]

i was using a tork wrench , i was listening for the click , the click wasfaint . i know i over torked it

[sprocket]

Well if you think you have them too tight back them off very slightly...or re-torque them...

They should be fine...

[tvnacman]

retorked head , adjusted carb , its raining just scooted around a few times seems good .

well the weather cleared up this morning , I went for a ride a soft one . changed the oil at my friends shop , plenty of alumium pieces , and broke the oil filter cap . called the wife and she brought me another one . I rode home , it feels like its lacking power , sounds different . I just don't have faith in this scooter anymore . I'm scared to take it to work in fear of getting stuck again .
