Update****

Still waiting for the carb kits soo I'm looking at the small fuel leakage i havew from the tank. looks like the fuel level sendor gasket is shot, might be leaking trough the unit itself. The sender was sending out a bad signal too, wouldn't give the right reading. Dismantled it and it looks very corroded. These parts are not avaible anywhere near here (Québec Canada), so i will try and find a gasket and give the brush and contacts a good clean, hopefully it helps a little. Wish i could still order a new unit from suzuki :p. 

 

 

In need of parts try OldMotorcycleShop web site, located in Calgary,  internet sellers for vintage bikes.

*Update*

I got the carb rebuild kits. Got everything back together and doubled check everything was good, floats etc... The choke circuit was unclogged after sitting 3 days in acetone. 1 day didn't cut it. 

fuel level sender Fuel leak has been repaired, very happy about this. i used a little Permatex grey fuel resistant sealant on it. 

new plugs in. The bike started up really well with the choke fully engaged. revs up to 3-4k with the choke on. Warmed up, it wont hold its idle very well and dies out or surges sometime. I went for a small 2 min road test and it ran better then it ever has for the first 2 minutes, then, once warm, it lost all power and I barely made it back, died out on me in the driveway. I checked for vaccum leaks with carb cleaner, didn't find any. I got the carbs synced but they werent that much out of sync. no difference. 

Plugs 1 & 4 are fouled, 2&3 have a nice white/slighty brown tint. 

I'm starting to think maybe theres something wrong with the ignition... because 1 & 4 are run off the same coil. I will look up what i can check about this system. I have a spare coil i might try out. All secondary and primary coils show the same resistance. Maybe cdi is faulty?

Assuming std coils then age takes its toll - not unusual for coils to start to fail once they get warm / hot. Swap out for a known good coil first. Ign. boxes a) won't be common, b) unlikely to be cheap and c) will be the same age as yours that might have failed so how long may it live? Swapping to an aftermarket ign. may be the cheapest / more reliable solution.

PS - old bikes with faults are cheap for a reason LOL!

[BushcrafterQC]

YES! ITS FIXED and runs like a dream. Man is this bike smooth. i'm used to 650 thumpers and this feels really nice! 

It was the ignition coil after all.

Put a new bar and mirrors on it. The P.O. was going for a cafe racer look, but I prefer this stance and actually seing whats behind me.

Thanks yall for the help!

haha yeah well i think it was a combination of both jetting and the coil. The choke circuit was blocked anyway on all 4 :p at least i know the bike alot more now!
