Throttle only turns about 1/4 inch

[bubba]

Sup ya'll, well I sold my Kat to a buddy of mine a few weeks ago and before he bought it, it sat for a few months. Well he called me up this morning to ask if I had put some kind of limiter on it. He said that ever since he's baught it the throttle grip only spins about a 1/4 inch and he said the bike won't go past 86mph in 6th. Anyone know what could be causing the throttle to not twist?

improper cable routing?? did you or he have the throttle cable off for any reason?

[shadowhunter04]

following with that idea...i'd check at the carbs to see if the throttle cable was adjusted properly... or... it could be a very corroded cable, you could try shooting some WD-40 down the cable shaft (worked for my clutch which was very stiff at first)

You could just tell him that your not supposed to go 86 mph

I'd check the cable as well.

[bubba]

yeah i told him to check the cable and he said he did and said it looked good.

Well, the Flux Capacitator will kick in at Exactly 88 MPH Marty. But tell him to remove the tank (His first learning project) and tell him to twist the throttle while looking at the carb. Tell him "See the little peice in the center that moves when he moves the throttle?" When he says yes, tell him to push that same peice in the same direction it was travelling when the throttle was turned. So he knows thats moving ok. Then tell him to twitst the throttle harder if it did move more with the finger pressure. It might be that the throttle cable just started to fray. Its possible theres a loose bit of frayed cable grabbing the inner sheath. If the throttle plates under finger pressure wont move beyond the throttle twist, then theres something else wrong.

What year is the bike? It might be that the cable is binding in the housing.

Tell him to pull the tank off, and see if he can rotate it at the carb end to WOT.

I thought that the choke cable on Kristin's bike was improperly adjusted.... and when I looked at it finally I realized that it had frozen.... a "scratch" on the routing had rusted and held the cable fast.

beat me to it

He found the problem. The throttle cable was rusted to the side of the housing, he said he sprayed it with WD-40 and he said it works perfect now.

I would replace the cable.

[bubba]

I would replace the cable.

i was thinking the same thing, but its his bike now, i'll probably suggest it to him the next time I talk to him.

+1 Dont need to add more.
