Title: Clutch
Post by: zcarlson12 on July 18, 2013, 04:14:35 PM

Hey guys, I came over here from the other site and finally am making a couple posts. I have a question on the clutch. I am going through and completely rebuilding my 89 ESR 310 bottom end and top end. I put all new seals, bearings, crank, bore, piston, etc. and I got to the clutch and found out I have a broken friction plate. Now I've read that OEM is the way to go on this but I remember pricing it out a while ago and it was pretty expensive. Now to my questions, What are you guys running as far as aftermarket clutches for mx and woods? Is there a place to get the OEM clutch at a reasonable price? Finally, I noticed ESR has a clutch kit, has anyone used this? Is it any good? Just to clarify when I say clutch I mean both the friction and fiber plates and springs. The basket is in great shape. Thanks for your help.

I took Neils advice on a clutch a few years ago, it's been working great so far on my 310.  Here's his post copied and pasted from atvriders:


Take out one of the 250R steel plates & put back in one 400EX steel plate.
 Replace the springs with CR500 springs.
 Put one of the 250R aluminum drain bolt washers under each clutch spring bolt, on the outside under the bolt.

 All this is doing is making the whole clutch pack thicker & in turn causing the pressure plate to apply more pressure to keep the clutch from slipping.

 As Honda designed the 250R clutch, the pressure is enough to hold once released, but not to great to keep the plates from slipping just a bit after gear shifting, a cushion of sort you could say for the trans gears.

 Once you add these few things to the clutch, it makes no difference the price of a new set of fibers should you replace them, be it a high priced or cheap as you can find, because this mod will remove just about all of the clutch slippage.
