sounds like you need to graphite the cables & make sure nothing is binding at throttle body.
that's how I have done friends Harley's' in the past w/ this problem. It has never happened to me. Old or cables get dry. U need to adjust them periodically as well. They stretch.

u will know just by looking at it while you give it a few cranks when not runny of course. You would need to disconnect cables from grip & pull the end straight up in air while you inject graphite lube into the cables. There is a special liquid lube that has a needle like injector tube attached too it that goes into the cable sleeve. It is not the powder stuff that you use in locks. I do this every 5000 miles when I svs my bike. You should not have to lube the throttle body spring just look for binding there & where STG said. So, you are looking for binding @ each end & lubricating them. I also do this to the clutch cable. You will be so surprised @ how nice the cables feel afterwards. They last much longer as well cuz it really cuts down on friction. Look at adjustment when done in your manual.

Hey Bandit

The throttle body butterfly is spring loaded , u can manually turn it , it should unload with a snap , at rest you can check for slack cable , it will be obvious, try Wd40

I would not use wd40 as it tends to attract dirt. PB blaster much better & it doesn't effect rubber parts. But I would never use either to lube inside of cables. Not saying you are wrong. Just my opinion.

I have been useing Lube One by Slick-50 for years and never had a problem.

lubero uno. What is that? How do you get it in the cables?
