I had a Suzuki outboard that was running like shjit. I tried everything. Eventually I pulled the carbs. They were immaculate. PERFECTLY clean as far as I could see. However, I took them to pieces, cleaned them and blew everything through with compressed air. Got them back together and the thing ran like clockwork.

It must have been a miniscule piece of something I couldn't see.

Are the in line filters NEW ? . Maybe remove them completely and try again , could have been contaminated from the work done on the fuel tank ! If pulling the choke improved the problem, then it sounds like fuel supply problems !

My bike did that when the diaphragm in the fuel petcock was torn.

when just sitting on the stand it revs fine..iv had different lines on it, iv had a different tank lifted straight of a running bike and still no change.

i had both sets of carbs of and cleaned yet again and they are clean, i even tried swapping the innards from both sets over and no change, fuel filters are new and clear, with no filters fitted its the same, the tank filter is also clean, iv had every single connection on the loom removed, changed ecu.coils,battery etc just incase but till the same but it doesnt feel electrical, its more a laggy feeling and the choke being pulled helping points to fuel..

its worse on a constant throttle. right at the bottom its fine, wide open its clean flying but the 80% in the middle is so bad you thing its about to stop and get pushed home..

who knows,

iv a complete fuel system inc tank il try tomorrow from a bike thats being ridden here so i know 100% its working

I saw on the fb group that the one thing you haven't swapped is the ignitor box - will you try using the one off the bike tmrw? Although the choke helping suggests fuelling, I have recently learnt from a book I'm reading that ignition and fuelling are interrelated in that a rich mixture is easier to ignite and can disguise an ignition problem, and vice versa. So you could have a weak spark for some reason which is helped by richening the mixture with the choke.

Have you also tried different HT leads and caps (I've slightly lost track of what you have and haven't tried!)?

...having said all this, the fact that it runs OK at full whack suggests that ignition is alright...

Has an airleak crept in somehow involving the airbox / carb seating / choke with the change of tank?

It's the noise a small garden sprayer makes when you squirt it :lol:

Sorry, I knew what I meant.. Or did I :lol:

I've been reading through this again & I had an issue very similar to this about a year ago & I did the exact same thing as you Fab.

It was ok at small revs & high revs but no middle. I changed everything like you've done but no change. I'd ordered new plugs & whilst waiting for them to arrive I changed them for a known :roll: good set plugs which I carry in my bagster.

No change, but in my head I'd eliminated that it was a plug issue.

Following day I was still on here asking for help, just like you. Then I hear the postman with the new plugs arriving. 10 minutes later it's running like a charm again.

It was the plugs after all that faf.

I'll never trust a used plug again for fault finding :thumbup:

Thanks for the reply Vara :D

I'm really pleased for you Rob you have your old bike back, something to give you a bit of a much deserved lift after all the aggro you've had. I know only recently you were saying how much you wished you hadn't sold it. That has to be a result in itself :clap: :clap:
