Pro Grip Lock-On 700 Series Grip Problems - 05 999‏

[Structure3230]

I recently purchased Pro Grip's Lock-On 700 Series Grip for my 2005 Ducati 999 and I am experiencing some problems. This will be my second set of handgrips as the first one I recieved came defective with one of the ears on the throttle handgrip was already broken (make sure to check the packaging from the start). Nevertheless I ordered another pair from parts unlimited and installed it. However when turning the handgrip throughout its travel (from fully closed to wide open throttle) the throttle handrip sticks in many places. I then adjusted my throttle cables to find that there was no effect on the situation. I went ahead and removed the throttle cable completely and found that with the grip installed on the bike I continued to experience the problem. The throttle tube is sticking even without the cables installed!Have you heard any similar cases to this effect? I removed the throttle grip from the motorcycle and assembeled the grip with the throttle rotor and found no sticking. Is it possible that the throttle tube is having problems? The handlebars aren't bent.... yet.

This is the second time I've heard of this problem.

If you mean:

Which grips fit my 748? Pro grips don't...

Then its a totally different problem - whats described in the previous thread is a variation in the size of the throttle rotor itself. What happened in the other thread was that the rotor was not fat enough and there was extra play within the throttle rotor and the rotor assembly (where the throttle rotor was not wide enough).

What I experiencing is no issues with the rotor but the throttle tube in the middle. Short of taking the good ole dremmel out I just wanted to see if any other 999's experienced this problem.

A problem's a problem, aye?

Yes indeed - both of us were/are sidelined by progrip's 700 product. In any case I left an email with Progrip Italy to see if they can shed some light into the issue. If I don't hear from them by Thursday then the dremmel is going to make an appearance.

Yeah this is frustrating as the riding days are counting down. With a name like Progrip I didn't think I needed to worry about fit and finish but with a lot of these "multiple application" parts I guess there needs to be some middle group in engineering to accomodate these products within a vast range of motorcycles. Too bad for us Ducati riders...

Well Progrip didn't get back to me (they didn't come through!!!) so the dremmel was out. After using a dial caliper I found that the measurements for the rotor itself on the Progrip was too big when it came to the diameter overall. Nevertheless I took the measurements and dremmeled the progrip rotor down to the size of the factory throttle tube. Under the attachements the area in red was the part I had to modify. Afterwards the throttle worked like a charm.

However within this whole scenario the guide pin for the throttle tube assembly now broke off ...so its ebay for me and more downtime. One problem fixed and off to another....

For anyone in the future who is working on this type of setup be carefull with the guide pin and make sure to measure the new throttle rotor before installing. If you continue to have problems identifying the problem area you can always use a paint pen and see where the rotor is rubbing with the throttle housing.

To say the least this will be my final purchase from Progrip as customer service is just as important as the product. Nontheless the product is okay - I just expected more out of the "proprietary carbon fiber" rotor as the finishing was bad. I hope my experience helps someone else in the future.
