I did a search but decided to start a new topic. Thinking maybe there are newer options now.

Here is the situation. My 01 DS is slightly modded. HMF, OMR carb mods, RWR CDI, 15t sprocket, I bought the DS six years ago. It has the stock clutch in it & I use RWR 40% springs. I use Klotz techniplate MX4 synthetic oil. 10-40w

Last year around now I noticed my clutch seemed notchy. 1st & 2nd gear were hard to work smoothly. I ended up adjusting my clutch more. In fact it really had no freeplay in the lever, but it made my clutch work alot better. I tried to move the teeth on the clutch housing spindle but I couldn't adjust it that far withit beinmg in a "bind". I rode all last year but noticed when racing my friends 450R that in 3rd, 4th & 5th the clutch would slip. Fast Foward to now. Changed my oil & took the DS out for a spring ride Sun & today. The clutch is much worse. It slips even when not raced previously. I tried adjusting it back & forth to no avail. So I guess I'm thinking maybe I will finally have to buy a clutch.

So as far as my mods what clutch would you guys suggest? I want reliable, easy to install, strong (won't slip) & the best price for those qualities.

Also, Should I reuse my RWR40% springs or buy 60% while I have it apart?

Thanks.

 

I would go with a Barnett dirt digger. Its a 9 disk set up (factory is 8). I used the springs that came with the kit. I have had it in my bike for 3 years now with no slippage problems, even with my 730 kit installed.

I purchased mine from HPR and I think I paid $150.0 plus shipping.

 

Yep....barnett 9 disk. Folks have been having a hard time contacting HPR latley so you might try Gary at TVI or The Bomb or even Alba.

 

HPR wanted $225, Alba was 199. I got it from a vendor in MI for $174, plus in MI I'll have it for this week-end. Hope all goes well!!!

Any other opinions on this..... Should I use the Barnett springs or reuse my RWR 40% springs? I read once where Barnetts weren't as strong yet MRDS is running a 730 on them! Whats the scoop?

 

I would throw the Barnett 9-disk clutch in with those 40% RWR springs and let er rip.

Be sure to soak your fibers for a few hours in the same brand oil your running in the bike.

Mildly sand the steels before installation and you should be good to go.

 

Yeah the price has went up on them for some reason. I have seen them on ebay for around $150.00. So $174 is a pretty decent price. You will be alright with the 40's but If it were me I would put 60's in it. I agree with Heads up racing on soaking and sanding a little. Be sure to torque the clutch basket bolts to 89 inch pounds and not foot pounds.

 

You can't torque them to 89 foot pounds. They will snap WAAAY before then! Trust me, I know.[img]i/expressions/face-icon-small-wink.gif[/img]

 

I called Barnett just to touch base with them. He said I should probably reuse my 40% springs as they may be stiffer than the Barnett springs in the kit. But if MRDS is running a 730 I'm sure I should be fine.... I'd like 60% spring kinda but hate to put any unwanted stress on my cable & teeth than I need too. All I know is for $175 this thing better GRAB!

 

btw, What purpose does sanding the plates do? What should I use & how long?

Also, whats the minimum I should soak the clutch plates in oil before & assemble them?

Thanks

 

It gives the fibers something to grab ahold of. I would use some 400 or 600 and do a light sanding on each side. I only soak the fibers for about 15 to 20 mins at the most. Just make sure you soak them in the same oil you run in the bike.
