...Get ur mind outta the gutter.....Damn! [sm=smiley2.gif]

After riding the Colonial Parkway today with the better half I was noticing a rattling sound. Tonight as I was putting away the scoot I again noticed the rattle but this time with the engine off. I traced it to my rear cylinder exhaust pipe mounting flange holding the pipe to the head was missing the rear nut and the fwd one was finger loose. The rattle was the flange hitting the heat shields!

I hope I didn't damage the engine in any way. I can't ride until I get to the stealership to get a new one. Better yet I'm gonna get 4 of them as I see this as a continuing trend!

 

Hi dr plastic i had the same problem with my sporty after i had my 1200 conversion done.I tightened them up 3 times and came loose every time.The last time i tightened them up i used a dab of loctite on each one.Its been a thousand miles since i did it and they are still tight.And like yours it was only the flange on the rear cylinder.Im not tellin you to use loctite but it worked for me.

 

be sure to put some threadlocker on the bolts

 

Will do!

I swear I put some on when I loosened them up to install my Straightshots. Guess not!

Thanks

 

I dont ride w/out both of mine! sorry had to do it.

 

A star washer under the nuts is a better idea than Loctite. The high temperatures reached at the exhaust port will breakdown the Loctite.

 

Why go to dealership for the nuts?[&:] Your local auto parts or hardware store will have the same nuts at probably half the price.....
