i recently bought a 1980 gs750L with the 16 valves. well i have a BEAR of a time to get it started. my friend who i bought it off had put a stage three jet kit and and k&n air pods for each carb. i can have the choke fully open and the battery charged or even with it hooked it to a car and i still have a hard time starting it up. has anyone had any issues with this? if so what did you do to fix this?

The first thing you should do is check/adjust the valves. I can usually go about 4k-5k miles between adjustments and then the bike gets hard to start. Also make sure the inside of your carbs are spotless and synced. You may want to richen the mixture screws to about 3 turns from lightly seated and/or try a slightly larger pilot jet. -
Clean the carbs and adjust the valves.
If you have good compression and a good ignition this should fix you up.Comment

How do I adjust the valves I have some knowledge but I'm no mechanic. And the carbs were recently cleaned and set and look like their brand new from 1980Comment

The carbs, how do ya know they look brand new? The outside of the carbs dont have any effect on the way they work
.
A rag thread, a hair, a grain of sand will goof up these carbs.
Your bike should start with NO throttle. Full choke only.
Keep us posted!!Comment
