HondaCB650

i have the same set up what jets size would you guys recommend?

looking for a tank that fits a cb650 1981. let me know thanks

if you know compresson is low and new rings are in order what size should u go with? i dont want to buy the wrong size because they are not cheap.

Darn thought The problem was solved, it is plugged all 4. I will check the suggestions u mentioned. And post an update. The fuel line is a bit Long maybe the angle is starving the carbs. And petcock is old I never cleaned it. Hope that's it.

i think you just solved the problem... i dont have any vacuum shut off valve there (automatic fuel valve). its a complete seperate assy right? i am posting pics off what i think u are reffering to. what is circled in red is missing from my set of carbs!!! DOH!!!

its an 81 cb650c. the carbs are cv type (vb44a). dont know how to check vacuum? the valve clearance is extreamly tight i am in the process of adjusting valve clearance at the moment. i believe the intake side should be .002 and the exhuast side should be .003 as the engine runs i do feel pulses of a...

could it be a vacuum issue, i read a similar issue and he had a vaccum issue dealing with a hose on the carb. i cant find one on my carb? also could id be a low compressin issue?

Timing ia okay and i have spark to all 4 cylinders. I have got to the source of the issue, not enough fuel is getting to the 3 &4 cylinders it is a carb issue. adjustment will fix this. On full choke it idles but any release of choke after that it dies. I need to adjust idle screws or something ...

okay update tank is new so i know thats good. also all valves are correct clearance. i am thinking the timing is off. any comments on that idea? i am going to try and adjust it but gotta find my gun. and just to make sure im doing it right can u post the correct timing deg. or a link for info thanks.

I am omw to shop and will try all suggestions. I will update as soon as I have some progress. Thanks for the suggestions and all the help. I'll keep u posted.

flowmaster 4 into 1 ceramic coated system? for a cb? that sounds awsome where can i get one? thanks.

cables are all check they are good. fuel is in all bowls thats a check. all butterflies move as should thats a check. they carbs are not sync'd i know that for sure. just so you know exactly my senario. i got this bike about 3 weeks ago from a couple who had not ran it for over 2 years it was in bad...

do you still have the choke cable?
how much? ship to 77406?

my 1 and 2 cylinders are firing but my 3 and 4 are not. the pipes are not getting hot. i put new plugs on all and i also put new wires on all. i am stuck!! can that happen if the carbs are not sync'd? is it possible that the coil is out? please help!!!!!

thanks alot for the tips ill go thru ur checks and see what i find.
