has anyone checked the float bowl? i had a flake of dirt in one of my bikes once fine until running on main jets then dirt sucked up and blocked main jet. throttle off, dirt drops away and runs fine.

They've had the (admittedly old) carb off and stripped several times Blues. I helped on one occasion and it was absolutely spotless. I agree though Blues, my first thought was that perhaps one of the jets was partially blocked. However, give it more air (remove the air filter and box) and it's off like a scalded cat, which suggests over-fuelling. It's very odd. I feel for HFG, I really do.

Hi Steela,

Sorry my suggestions have not help. Looks like Nitro and friends are covering all the bases. Weird...as it has been said, there is not much more to check. I would check the carb too, as it could have been 'set-up'or modified for some reason, the good old Haynes manual will have the right jet sizes.

I doubt both carbs will have the same problem. Have you checked the fuel supply to the carb? It could be fuel tap blocked, or if it is a vacuum tap could be a split vacuum pipe. Just two things that havn't been mentioned yet.

One more thought.Have you checked the inlet manifol. Any leaks here would make it run lean and might explain why it runs OK with the choke on.

So if the bike runs like a gud un with the air filter off etc then yr problem must be with fuel rather than electrics ... anyone checked the mixture screw on the carb? i.e. is it working properly *runs away quick just in case they have*

Yes Stella .. the inlet manifold rubber was checked with carb cleaner and WD40 for leaks .. None at all .. I do think it`s running lean .. Anyone near to check the main jet ?

I still can't imagine both carbs have same jetting problem. So I would assume jets are OK. Try checking compression with a guage. If air is getting in, via leaky head gasket for example, that would lean mixture off.

Eventually fixed my problem by taking it to a fixer with rolling road and DYNAjet tunig equipment and found a faulty coil. While I was tinkering myself I had lots of advice from people, much of which has been mentioned here, but one thing I havent seen mentioned yet is the Diaphragm. Even the slightest pinhole would give symptoms you are getting. As you've changed carb and tap this should be fine, but worth a check.
