Throttle cable adjustment?
Was having issues with the throttle snapping closed when releasing grip. Seemed like you had to "help" it along when letting off the gas. I grabbed my manual and set cables as per manual instructions, and although it seemed i got my WOT set properly, the throttle still "hangs" really close to closed throttle. I still have to give it a little twist to shut it.once shut, it stays shut. For example. Going down the road at 45 you only hold the gas slightly open. If i let go, it hokds there, maybe slowly close on its own if i hit a bump. How do i fix this? Seems the adjuster is out about as far as it will go

When was the last time the cables were lubed?
Are they the originals?

Lube cables, and make sure the throttle "drag" screw, below the hand grip isn't too tight.

You said you have a manual?

toastedroach420 08-11-2017 09:48 AM

Haha im at work and the manual is at home, i didn't know if it would say there or not. Is it easy?

Pretty easy.
Hardest part is probably deciding what lube to use.
A bunch of options out there. The Moco (used to?) sell a "special" lube in it`s own little applicator.
Other companies make "specialized" cable lubes as well.

Have heard of people using anything from 3 in 1 Oil to liquid graphite. :dunno
Always wondered how well some of the lubes designed for firearms would work.

Two notes of caution. 1) Whatever you use. It should be a very light viscosity.
A heavier weight can attract and hold dust and dirt more readily. As well as get stiff in cold weather. This will gum up the cable.
2) While I do`t think they make Teflon coated throttle cables. Never use any sort of lube on one that is.

And. While you are at it. Would probably not hurt to lube the clutch cable. As long as it is not Teflon coated.

If after oiling the cable the situation does not improve. There is a chance one or the other cable has started to fray. A strand of the cable has cracked or broken and started to unwind. If that is the case then the cable(s) need replaced.

According to a couple threads on google you take off the housing by the throttle grip to reveal the cables. Spray lube of your choice into each cable until it comes out the other end at the carb, and mop up the excess. Then readjust. I mean its not awful, but im very particular about these things and any lag is too much lag in my opinion.

Ok thank you sir. I think the clutch is fine, ill leave it alone. I suppose the cables need the lube after sitting stationary for 4 years,

Have seen the lube come in bottles with little hollow needle type extensions that allow you to drip it down into the cable sleeves.
A little less messy. I have had good luck with liquid graphite. Found at any hardware store.
And serves a double purpose for locks around the house as well.

But yea. That procedure sounds about right.
And I hate anything that is not right too.
Especially on my bike. :nod
