Just got this raid a few days ago and so far it's been running great apart from a couple of minor issues. The first is the carb leaks from the diaphragm gaskets and an issue I think is linked to that is occasionally what sounds like the carb area will make a loud pop sound and the bike may or may not stall.
I'm guessing this leak is maybe causing air to get into the carb which creates this pressure build up and the pop which temporarily effects fuelling so it stalls. Any ideas?
Ah ok. Say I'm riding it for an hour. It might pop once in that time. For the rest of the time it runs totally fine. Idle is fine, revs come down etc. Would that be consistent with a manifold issue or would you expect it more frequently?
Difficult to say for certain. If it is a problem for you then best to check it out using the test Pete suggests on the other thread. Otherwise it will require a bit more work if there isn't an obvious visible issue i.e. a split in the manifold or the rubber moves on the ali stub when you wiggle the carb.
Looking at that carb thread it shows up an issue with the aftermarket manifolds where the notch is in the wrong place. Are they all like this or do any of them actually work? I'd rather spend £6 than £40 if possible.
