hi all
i just fitted a new stock exhaust to my ET2 50cc and after driving it around for 20 minutes there was smoke everywhere.
turned it off ... started it up again and ... no smoke!
the casing for the clutch and variator was scorching hot though as was the rear wheel and the new exhaust.
could there be a problem or is it likely that the smoke was the WD40 i'd used earlier burning up???
thanks in advance!!!!

i don't think the wd-40 would make that type of heat, sounds stupid but... was everything put back the correct way? also i think the vintage thread could help you better if it was a problem with a two stroke motor. but give it a couple days in this forum. good luck.

WD40
it will smoke for a few hours, just let the oil burn off, Its a engine they tend to get a bit hot, but possible your running lean

ahhh ... google is a wonderful thing ...

running lean = more air than fuel
running rich = more fuel than air

i'm hoping and assuming this isn't the case as the RPM's don't seem "erratic" in anyway although i did remove the air box and filter to access the variator casing the day before.
in honesty though i'm confident i put everything back as it was supposed to.
no bike riding for me though until late tomorrow so if i'm still having the same issue i'll look into this issue.

thanks

It may be air in leakage from the air cleaner. but I'll bet it maybe in your head, lots of people find phantom problems after working on our on bikes just ride it for 50 miles or so.

I have to admit I was considering it might just be in my head ... what if I haven't tightened this? what if ...? ... etc.

This makes alarm bells go off - did you touch anything else other than the exhaust?

now you're scaring me!!!

I had removed the casing the day before to derestrict the variator but couldn't get the bolt off as no variator locking tool so just put the case back on.

After the initial heat wave it didn't get too hot the second time. Will give it a good rag tomorrow/friday and see if it gets hot again.

What are you thinking could be the cause of the increased heat to this case?
