Default Wet vs Dry clutch

Just interested in everyones opinion on clutches wet or dry. I have a wet clutch set up on 65-900, and have never had issues although originally it was dry clutch with the derby cover. I dont know of any differences in feel or performance. Anyone want to chime in on this?

I think the dry clutches lock up better, however if your running a primary chain it has its own issues then. I would think it best to run a belt with a dry clutch.

chain with a wet clutch. (my preference any how)

I'm finding out my kevlar clutch hasn't like any lube I've tried. it works best dry.

Well, without getting too wordy, I think the dry clutch performs the best, but the issue is keeping it dry.

Now with the new wet/dry plates slipping is less of an issue, but I have recently found certain wet/dry plates stick together and are really hard to break apart when sitting and the oil gets gummy on them.

Going to try ATF this season out of desperation, but that is another topic.

i fear of cross contamination due to a failing transfer valve. i have had no trouble with my plates and striaght 50w oil in the trannie. if it sits too long (like a month or more) it slips slightly in 3rd, til i sling the oil off the plates with a good 55mhp+ blast then its all good again.

the main reason sporties slip is improper adjustment. not the type of oils used. follow the FM to the letter, take no shortcuts and it will treat you right for years to come

There is good info in this thread:
http://xlforum.net/vbportal/forums/s...d.php?t=966372

There are opinions, and there is experiences, its up to the owner to decipher the two.

Default This is always a good subject

The dry clutch performs right out of the garage. No sticking plates that rattle the hell out of the transmission on that first shift, no slipping. I personally think that the dry clutch along with the trapdoor was one of the Sportster's design triumphs. The wet plates work, but not as well, they were a less expensive way to make a clutch, if you have any real serious power, they can and do slip and wear out way quicker than dry plates. If you get on the dry clutch with the silver paint or sealant on those loose rivets, seal the cover with silicone instead of that paper gasket, it stays dry a long time and the plates can just be hit with a torch, dried out, sanded a bit and they are good to go.

Run the same engine oil in the primary is another bonus, and changing to a belt??? That's a reasonable solution to a non existent problem.
