Please Help I'm Desperate

[litshoot]

So dyno doesn't offer a jet kit online for my bike 77 gs750. so i emailed their tech department. no luck. they have at closest and 80 gs750. what should i do does anyone know what size i would need. i want to do a stage one kit for now just to get it close. also, should valve clearance be on the low side or high side. most of my valves are close but one is very loose clearance. should i fix the one for now because the others are all in spec. or go the full nine and bring them in tight. thanks

Rather than go tight you should err on the side of loose for your valve clearances. What you definitely don't want is too tight as you'll lose compression and start to burn out your valves. Spec is .03mm to .08mm but .1mm is fine.

You've also got VMs on a 79 750 so imho you're throwing money away trying to buy a Dynojet kit anyway. These carbs are very adjustable anyway (with cheap jets if necessary). If you post your set up (air filter and exhaust) on here someone is bound to have a similar set up or we could talk you through how to do adjust things.
