I just got home. Yesterday, I noticed the throttle had become a little loose, but was still popping up good. I had adjusted it to where it was perfect. Very little wiggle in any direction and snapped back up very nicely.

Today, after riding around town for errands, I was about halfway home when I decided I was going to romp on her a bit.

I hit first to near red line and released to shift to second, when I goosed her to second, I felt a snap and the throttle rotated about a quarter of the way without resistance before catching again and I was able to get her home.

It seems to be fine once I get resistance, but goes between a quarter or a third a-way around before hitting the resistance that was at the top (like it should be). The top third-ish will stay at the top, but it is weak.

I tried using the adjusters to fix it, but they only help a small amount. I am outside the range of their adjustability.

I have Kuryakyn ISO grips with a throttle boss. Came on the bike when I bought it.

The only issues I've had are the clutch side turns when it gets really hot out and someone stole the endcap off the clutch side. Bastards.

Now, I have an issue I don't know how to deal with.

Can I just take them off an reinstall them? Any ideas what the pop might have been? Thanks guys.

Im thinking one of two things...
1 - the throttle tube, where the cable connects, has broken off.
2 - the cable fell off the "guide". I say this one cause I found mine to be that way when I swapped my master cylinder today.

There is adjustment at the carbs as well. I would at least take a look down there and ascertain your good on the business end.

Can I take the throttle grip apart and get it back together, again? or is there more to it?

I will look on the carb end.

Un-do the screws holding part 12...under that is the cable connection to the throttle tube

On this view you can see the throttle tube and cables

You can do it with out much trouble at all. I would take the screws out and have a look.

Same grips - the little plastic notch that held the metal pill at the end of the throttle cable in broke off. Very easy to replace the grip - but you have to have a new grip to replace it. The tube is integrated into the grip - if it's removable, I didn't figure out how. I ordered a new replacement throttle grip from kuryakyn. Took all of 5 min to replace.


...you're gonna feel a little pressure....
