Throttle hard to twist

[MtnMan]

Hello,

After a thorough cleaning the carburetors on my 1981 GL1100 were rebuilt using Randakk's rebuild kit and new throttle cables were installed.

The bike starts and runs very well now, but the throttle is much harder to twist now (~3 times harder) than before.

It still snaps back. The cables were routed the way they were routed before; the throttle was easy to twist before the rebuild/re-installation.

The throttle grip is lightly greased.

Any input how to fix this is much appreciated!

Thank you,
Armin

Disconnect the cables and be sure they move freely. Eliminate the possibility of a missed kink or throttle grip issue. Can you easily rotate the throttle plate by hand? The back pressure on the spring should not have changed as a result of rebuilding.

Were the new cables lubricated in any way? And...are you 100% SURE they are routed exactly the same way? Also, the new cables may be a slightly larger OD, making bends in them tighter...that could be part of the issue. :yes:

Are the new cables OEM? O are they aftermarket ones? Lubing them might help a bit. :yes:

I bought a set of cables on E-Bay, I had to replace the pull cable because the one I got in the set was making it hard to open the throttle. I had to change the clutch cable to, it was bad. Those cable kits they sell on E-Bay are not the best.

Thanks guys, for the valuable feedback!

The cables were indeed from eBay. Checked routing, lubed the cables and also put some WD40 on the linkage. This helped and all is good now! :Egyptian:

The bike feels much "lighter" now and is a pleasure to ride.

WD40 wont last long. Try to get a drop of light machine oil, even ATF on the linkage instead.

A good lube for cables or other applications would be tri-flow.It has mini-spheres made of teflon in it.https://www.ebay.com/itm/Krylon-Tri-Flow ... 257caf07fb .Was recommended to me by a mechanic long time ago.There should be a webpage with more details about the product.

Thank you! I ordered a can of Tri-Flow to see how it works.
