GL1000 Shift Linkage Slipping

Postby dbmcd » Wed Aug 27, 2014 3:49 pm



After fixing some other problems, I finally start it to ride around the block and find the shifting was hard. Not wanting to change gears easily. I parked it on the stand with the rear wheel off the ground, started it and went through the gears. When I shifted using my hands, I noticed the shifter seems to slip. There is a lot of resistance and travel and then a click into gear. It acts like a set screw on a shaft is slipping but finally engages. I would like to know if the problem would be behind the front cover or be more likely internal where the case would have to be split? I have had the front cover off several times replacing o-rings and fixing my water pump leak. I don't really want to remove that cover again, but I would also never consider splitting the case. Any comments would be appreciated...

When you put the front cover back on, did you use a new, OEM gasket? The clearance between the inside of the cover and the shifter mechanism is extremely close - so close that if you use a thinner, non-OEM gasket (or worn, compressed OEM gasket), the mechanism will bind up on the inside of the front cover.

That must be it. Would you believe I was a "smart guy" and didn't use a gasket, just gasket sealer! The reason was because I didn't think the o-rings had enough "squeeze". I will pull the cover off again and install an OEM gasket. I'm sure that will fix it. Sometimes it doesn't pay to be too "smart"!!! Thanks for your help. I'll post the results when I finish.

For the record the gasket thickness was the problem. The shaft above and slightly to the right of the water pump hole would rub on the cover. I saw some rub marks on the two surfaces. I re-installed the cover with a proper thickness gasket and that solved the problem. Evidently the Honda engineers designed this close interface to hold that shifter shaft in place. I pulled on it slightly and it seemed to want to come come completely out if I continued. You learn something every day! Thanks again...

You're not the first one. People who use Saber Cycle gaskets have this same problem (they're paper-thin).
