York diaphram clutch
I'm looking at buying a York diaphram Kevlar clutch kit and one thing I would like to know is does the hub supplied in the kit replace the old 3 finger hub I have now? And this question might sound stupid but is the foot clutch conversion thats clamped to the downtube called the Mousetrap? I was reading in the archives that if you run a diaphram clutch you have to get a Mousetrap eliminator is this correct? Thanks.

Re: York diaphram clutch
If this is what you're referring to, then the kit comes with it's own hub that replaces the original 3 stud hub. I don't see why you couldn't run a mousetrap with this settup... http://www.lowbrowcustoms.com/index.php ... ail&p=2209" onclick="window.open(this.href);return false;

Re: York diaphram clutch
The problem with using a mousetrap is that the diaphragm spring cannot return the mousetrap to its engaged position and there is not enough adjustment to soften the overcenter spring enough to allow it to do so. So eliminator kit it is!

Re: York diaphram clutch
Why are you wanting to move away from stock? Are you having issues?? A properly tuned stock clutch can work very well...

Re: York diaphram clutch
I always thought those "York" set ups looked suspiciously like the Primo Rivera units.

Well its like this JD I just bought the bike and the only parts of the clutch thats on the bike is the clutch basket and the hub nothing else, so I've heard some positive things about the diaphram clutch so I thought if I have to buy a clutch it might as well be a diaphram.
O.W. that would be good if it was a Primo the only thing I do know is thats its suppose to be made in the U.S.A. The bike has a 1-1/2" belt drive on it and it has a Primo belt but I don't know if the rest of it is a Primo.
I've seen prices for the mousetrap eliminator anywhere from $50 to alittle over $100 so how many people are making this eliminator? I've seen the Custom Chrome name and Howards and the rest they just weren't saying who made them. I seem to remember reading that there was only two companies making them.

Re: York diaphram clutch
I absolutely agree. I have always seen these diaphram clutch setups as an expensive fix to a very simple problem. There is a reason HD stuck with the basically same design for more than 4 decades. There are very good original 4-speed type clutch parts out there nowadays, along with the long roller bearings, etc. Properly set up, there is no reason your original clutch can't work more then reasonably well to your satisfaction.jdpan wrote:Why are you wanting to move away from stock?

Re: York diaphram clutch
i'll go plus three on the stock clutch.
cheap, plentiful and mostly trouble free if set up properly.
oddly enough the stock HD clutch looks very similar to the steering clutches in my john deere bulldozer, and very similar in size too!

Re: York diaphram clutch
I run a york diaphram with an enclosed belt drive,and a mousetrap..the yorks sealed bearing doesent need the lube that the 3 or 5 finger clutch hub needs ,,so u can turn off the oiler .....works great !

That was another reason I wanted to run the York diaphram clutch get rid of some of the oil slick, my neighbor is running a diaphram on his pan but I don't know if he still runs the mousetrap. So how did you get your clutch to work right while using the mousetrap Blewcrab? I plan on running a open primary, at least thats my way of thinking right now.

I just bought the bike at the end of August hplhd and I'm trying to get it back on the road but there's oil on the belt, I'm not sure where all the oils coming from probably the trans. I have to take the inner primary cover off to see. I want to run an open primary so the sealed bearing in the Yorks hub would work well for this.
I see there's a couple people on u-tube that cut a groove in the trans. bearing output spacer and installed an o-ring on the side that I guess works ,another guy machined a whole new spacer out of thicker stock but he hasn't put the bike back together yet to see if it works.
