1979 GS750 - Dies in 1st

[Guest]

Hey guys! I grabbed a 79 Suzuki GS750 end of season last year and had it with a shop here in town all winter as they did some cosmetic work on it plus got some of the wiring / fluids checked. However, I’m having an issue now that didn’t exist last year - the bike dies randomly at idle in 1st gear. This created a number of sticky situations at red lights riding yesterday. Any ideas? For clarity: it’s fine while riding, fine even riding in 1st, it’s only as I slow down and come to a stop that it tends to die (and yes I’m holding the clutch 😅). It is also fine while idling in neutral, it's only when i'm idling in first with the clutch pulled that it dies (and yes my kickstand is up )

Any help would be much appreciated!

Valves adjusted?
Carbs cleaned?
Carb synced?

Have you adjusted the idle screw?

Clutch adjustment?

I’m with Rob. Maybe your clutch plates are not completely disengaging when you pull the lever all the way in. If your sitting on the bike in neutral, when you pull the clutch lever in and kick the shifter down to First gear, do you get a big lurch forward and bike wants to stall?
