Not firing on all cylinders

[Lloyd]

Hi Guys

My 750 does not want to run on all cylinders, coils are good, new plugs have been put in, carbs have been cleaned but the motor still seems like its not getting enough fuel or enough spark, Please help

Hi Lloyd,

I see you have found your way to the right sub-forum.

Tell us more about the known history of your bike...there are plenty of things to try to track down but a little more knowledge of the problem might help point you in the correct direction sooner.

Well, my clutch cable snappen on my way home, luckily really close to home, I bought a aftermarket rubish cable but eventually got it replaced, started the bike up and as soon as I pulled away it died.

So I decised I'll do a service, replaced the plugs and filters and added new oil, now the she starts but doesnt idle or rev up properly, if I keep it running for a while it eventually just cuts out.

You need to delete the other threads you started with the same title
they are not in the appropriate forum and are a distraction

Keep posting and responding only in this thread in this forum.

they have already been deleted, my apologies, new to the whole forum thing

Went through same drill last week. #1 pipe cold. Spark good, and a shot of carb cleaner through manifold sync hole offered rpms, telling the tale. So, off with carb rack, removed #1 jets and sprayed all orifices through, again with carb cleaner. Never actually saw a "carb booger", but she runs tip-top now. Maybe you'll get same results.

Note: carbs are on a running, (mostly) maintained motorcycle.

How about a few pictures of the bike in it's present condition? Or barring that, what has been altered or what is missing, if anything, from the bike?

[Lloyd]

Thanks, Ive stripped and cleaned the carbs twice to be sure, I have a strange feeling though it could be restricting fuel from the petcock, do you think that could be an issue?

The bike is used daily and maintained as regularly as most

Nice bike.
Pull the plugs... what do you see color-wise?

[Lloyd]

Ive just replaced them, I'll have to pull them again now and check after running it,

Thanks she is still really original, hard to find here in south africa, not very popular though
