PB-80 For SideWinder, ready for primetime.

Mike what was the cost of the P80 clutch,and are you still planning on trying one this year? Do you think it can handle 270 hp?And turn it up to 9000 rpms.

Right around $500 Pete.

I'm not sure if I'll get a chance to try it. I know I'll need a different puller to run it. I know it will do 240 as I ran it on my 1200 Doo, I know it will do 270, just not sure for how long. Just know it's not going to be a good drag clutch by any means.

Precision Sports is running them on their big power 1200's, but they may be doing some billet spring cups as well. The spring cup and blocks will be the weak points.

I believe precision’s only runs a dual spring set up. No billet parts

Thanks Mike,not a bad price,and I am not a drag racer,but I do value my life,sense I have a new rebuilt heart,i want to keep my life,and just not happy where these yammie clutches are headed,now that a lot of us are tuned to 270 range,i also don't mind low engagement either,i do know you and Dan had them on your doo,s and liked them,but tuning them is not hard,but not many options either. Thanks for your opions.
 
I plan on testing the pb-80 on saturday. I wont be able to run it on the timers but I will kind of be able to see how it compares to the yammie clutch. I will be trying
a couple different setups to see if I can get the pb-80 to somewhat run cool. I know on the 1200 doo it ran hot but it didn't seem to hurt the performance and the belt lasted
fine. I will report back with some findings.

Thanks Woody,i will be waiting for your report.
 
Can’t say for a big power sled...but bone stock the calibrated PB80 works awesome.

Had a PB80 on my 3 last sleds and plan to have many more.

I’ve only seen one catastrophic failure and I think it was just bad luck. Belt blew at WOT and jambed in the cap. All 3 blocks came out spread some washers in a buddies clutch bay (in a 1200)
 
Ordered one up to try last week, I got the first one sold in the states I know. I ran the PB-80's on my NA 1200's Doo's and also my last turbo 1200. The TRA was a ratteling bucket of bolts, much like the Yamaha clutch is on the 998, so as we put them on the 1200's, they quieted right up and got rid of all the clutch rattle, and I suspect the SideWinder will as well. It is not, nor will it ever be a drag race clutch when you have good traction, It will however be a great trail clutch. The performance should be as good as the stock Yamaha clutch other than the belt grip on take off if you have traction and are not spinning, but once engaged on the belt, should be an equal to the Yamaha clutch performance wise with a lot less to go wrong, like breaking and binding springs, rollers not spinning and flat spotting, worn bushings in rollers and things like that. It is also super easy to change weight and springs on, no need to take the clutch off the engines crankshaft, just remove the clutch bolt and large nut to change weight for RPM, slide off the movable to change the spring, I use a spring compressor to make it easy for spring changes.

It could very well run hotter as it has less surface area acting like a fan moving air compared to the Yamaha clutch with its larger alum. cooling surface. The cover on the PB-80 is fairly smooth steel that the shoes push against. So I have a hunch it will run a bit hotter just because of the design of being more compact & confined. It remains to be seen if it will be an issue, but it wasn't on my Doo's, so see no reason it will be an issue on the Yamaha.

The PB-80 for the Winder is P/N 1100-0312 and the clutches are available now. I took it apart this weekend and took a few pics, checked on the spring. It comes with a #1151-1135 spring which is a 900-1300 newton, So in pounds that would be a 202-292 pound spring. I know from testing I did on my 240HP turbo 1200 that is going to be very close as I also ran the 1200 at about 87-8800 RPM. The disappointing part for me is the pucks came with no mass weights, which IMO are going to be needed with the higher power tunes. The shoes come weighted at 110 gram total weight and contain 11 pucks in them, which does not seem like near enough weight to me, but I have yet to try it out. I ran 110 grams with a lighter spring than this in my 1200 NA sled at 8500! It does come with 9 extra pucks included, but not installed, but that still will not be enough weight for tuned sleds making over 240 HP. Mass weights will be a must when you get up in power and you can't go over 15-16 pucks and screw in the holder, you must install the mass weights to get over that much weigh in the shoe.

The shoes have changed a bit as they now have a piece cast on them that will not allow them to be installed backwards, which will be a nice thing. It is an OverDrive clutch measuring 8.2675" on both the movable and stationary. It is setup to uses the stock belt width.

I'm in no way stating this clutch is going to be better in any way just yet, I just wanted to give one a try compared to the Yamaha rattling bucket of bolts and having much success with the PB-80 on my 1200. I'm still going to be doing a bunch of testing with weights and springs with the Yamaha clutch also. Should be fun!

Pointer below is pointing to puck installed backwards not fitting properly, it points to the new cast in protrusion on the shoes that will not allow the shoe to fit in a backwards position as it could prior to this cast in protrusion. So this is new.

Pointer below shows the shoe in the proper position and the new cast protrusion in the proper orientation and shoe fitment.

How often would we need to change the rubber pucks in the PB80 with the sidewinder horsepower ,guys were telling me that after 1 long road trip on there harley's and the rubber's were worn out and how much are they or do they sell a rebuild kit?
 
There are no rubber pucks. They're made of some type of composite plastic material. I don't think they where out very fast. Had them on my 1200 Doo and had over 3000 miles and we're still fine.
 
The plastic pucks, I've yet to see a clutch that they needed to be changed... 14000 miles on my MXZ 1200 still looked new.
The spring retention cap is usually what could fail under big power. Maybe the hex holding the outer cover, but I've only seen that go bad on a clutch that wasn't assembled right...

The pucks are a composite material. Every part is replaceable on the pb80. I replaced all 3 of mine when I ran it on my 1200. They were about 11$ a piece
 
Any more feedback on the PB80?

I noticed last night that my stock primary has a small chip out of the spider. If Yamaha won't warranty it, I may try a PB80.

Anyone know where I could find one? All the online sites say they are sold out.
 
I put mine on for a couple of miles and can tell you its very quiet! But I had other issues I needed to sort out, took it off and haven't gone back to it since. I didn't want to be chasing too many things at once.

I'd sell it you you if you want to try it, I have the clutch, puller, mass weights and holder for it and would ship it to you for $600 all total if you want it. When you start buying all the things that go with it it adds up pretty fast.
