Title: Leaks at cylinder head/exhaust downpipes
Post by: Seamus on November 03, 2008, 12:52:59 PM
Hi All, I am at it again. I have been fiddling with the K1 trying to eliminate some popping/backfiring in the exhausts. (usually on the overrun)
Done the points/timing exercise and the advance/retard is working fine. I will need to balance the carbs at some stage, but I have noticed some gas blowing from the exhaust downpipes. The previous owner fitted a new set of standard exhausts and looking at the head, the mounts have also been replaced. It seems to be leaking where the slots are machined into the pipes just by the clamps (Hope this makes sense) Before I take it all off, is this unusual? Apologies if this is a daft question, but I have no experience of these hondas.
Thanks again
Seamus
