I have an 06 sg with 40000miles. The shifter arm that is attached to the tranmission loosens up once every year. I have taken out the bolt,cleaned the threads,applied blue locktite and reinstalled. Lasts for a season then loose again. What else can I do?

 

The shaft that lever is on is splined, Sounds like yours is beginning to strip out. Heel shifting tends to be abusive to the splined shafts.

Yep, those splines will start getting screwed up. Both on the shaft, and inside the shift lever. I just went through the same thing, and I just changed the lever on mine. The complete primary has to come off to change it. The lever is less than $25, and if you can do your own wrenching, I'd recommend taking yours apart and at least checking the splines on both pieces. Go ahead and change the lever too. Some guys have had good luck putting a longer bolt in the lever, with a nut on the bottom. It lets the whole thing squeeze a little more. If the shaft itself gets too boogered up, it's a major pain in the *** to fix. The whole tranny has to come apart to change the shaft. edit: btw, that shaft is almost $160.

 

My 04's doing the same thing the past couple of years and I have taken out the bolt,cleaned the threads,applied blue loctite. I have heard of the longer bolt and nut trick so I will probably try that this winter!!

 

Try putting in a regular bolt w locktite and then you can get a socket on it and get it tight. Works 90% of time according to my indy.

 

Also you might use a dremel and open up the pinch slot so that it can pinch tighter if you understand what I am talking about. While in there change the shifter shaft seal as you do not have to go into the tranny to do so.

If you have shift levers that are not stock (doesn't matter which ones), there is sometimes chrome inside the splined area which makes the "teeth" less sharp. If that's the case, it will round off the teeth on the shaft.

Sounds like you need to replace the shaft and while you're at it, closely inspect the inside splines on the shifters. If there the teeth inside are not "very sharp" looking, then replace the shifter(s) as well.

I have seen this on the (way over priced) HD shifters as well as various aftermarket ones.

 

good point

Allens are a pain so I use the socket type. I then can use a ratchet to get it tight. 34,000 miles, so far no problem. I do carry my heel shifter in my saddle bag just in case.

Drill the threaded section of the hole OUT and put a slightly longer bolt in with an acorn nut . Tighten it up and it will never come loose again. Done it on many bikes. If you use the threaded section of the lever and only put a nut on the end, it will not pull up tight as it will pull against the threads not tighten the pinch point.
