S3 Head

Featured Replies

hi i have posted a question on the sherco specific forum about issues with sealing the s3 head i have,

i am also posting here as im not sure if someone may have had the same issues on a different bike.

issue being water is getting into the barrel after running for a few seconds it also does this with the old head but this was tried with the old o-rings (so not really relevant i dont think)

it was bought new and the barrel has been re-lined by langcourts so im pretty sure everything is flat.

is it a common issue with these heads that the o-rings seem to small for the recess and also how do the head bolts seal as water seems to get passed them.

thanks

If its happening with the old head, and you have had the barrell worked on, I would certainly looking for the cause of the problem and not thinking its the new head.

I had the same problem with an S3 head on a Sherco. Contact your dealer or importer as I am told there are actually special O-rings now just for the S3 head
