Starter Clutch driving me nuts, Good thing for the hills here

Ok I have a `96 1340 Road King and I am about to replace its 4 Starter bendix clutch. I have 66000 miles on her and it seems that about every 20000 miles she spits a starter drive. Anything I am missing here? I am running a gel battery for the last 7 years which has served me well only replaced 1 in that time and has 360CCA on it so there is plenty of power in it. First Starter clutch went at 8,000 and Harley replace it with an OEM under warranty. 27,000 miles give or take 2nd one went in, was a aftermarket, 47,000 another Harley OEM and now 66,000 miles here come the 4th. Going aftermarket just not going to spend almost triple price for OEM. Any one having this same problem? No big motor, mild cam and true-duels carb work and such.

HRK, Yes I checked and cleaned all the connections to and from the battery, I already had in place a starter ground to the battery even put in a known working battery and that dreaded sit and just spin. Did as many test before pulling her apart which is a pain in the A$$. just ordered 2 New High quality starter clutch, just going to take a bit to get it living on an Island n Christmas rush. The one that is not working is a OEM HD from the stealership in Lisbon at a cost of almost 300.00 US the way I go through them I ended finding one for a lot less, The bearings on the old one I replaced are in excellent condition so I am pressing them off and just replacing the bendix and sleeve. doing 2 of them for the price of 1 HD, this way I will have a spare on the shelf. going to use a lot of bearing grease to make sure there is plenty of lube. I was just checking if I was missing anything, since almost new she has gone through so many?

Thanks HRK I will look him up, it is not so much the price for the item it is the customs at 25% and 18% tax I have to add before receiving the item and that also includes the shipping prices listed on the invoice. Anything from Non EU countries get this added. The Harley Dealer in Lisbon Portugal had already add the fees when the Part came from the USA to Europe. It kinda sucks so I try and order in the EU to avoid all the extra fees.

Wish it was that easy, they look at all items from non-EU shipments and change for used items like they were new. Some person check and appraise item even if they don't know what it is or what it fits. Sucks.

When I put in my S&S V111 my starter went out. It had 104 thou on it anyway. I called S&S for starter recommendations for their engines and they said to stick with HD. They are made as well as any of them. I kind of went with their recommendation but installed an All Balls starter clutch.

It worked great except I still had a stalling problem on hot starts and was chewing up the starter gear so I installed a different gear set. The stock gear is something like 104 teeth, I went with a 80 tooth set. It's got thicker teeth. Works just a well too.

Well I am back up and running, ordered one from the U.K. aftermarket and save a bunch. The OEM has a spacer attached under the gear and the new one does not it is all gear a lot thicker than OEM hope this means that it is bigger bearings and springs, crossing my fingers. The new one did not come with bearings on either end, just repacked and used the ones that were on the OEM as they were in excellent condition. Just a pain in the A$$.
