puch mk racing performance E50 clutch -TEST-

I am doing an official test on the clutch treats is selling called the:

puch mk racing performance E50 3 pad clutch

I installed it on Rodney's old Cobra with a Treats Reed Kit, CDI, treats pipe, 14t/42t gearing, e50..

Here is the run down:

Stock it basically feels like a standard 3 shoe puch clutch. It really feels smooth though and if you were running something like a gila and or a HPI internal rotor CDI the stock spring setup would probably rip..

Since I dont have a hyper beast 80cc kit or anything of the likes the clutch performance for a 210 pound rider is not totally cutting it IMO..

So I cut 4 loops off of the clutch spring and man was it a bitch getting it back on.. cool thing is i never had to pull the clutch to snip the spring..

So 4 loops was a noticeable difference and it rips up fairly steep hills now.. sort of feel like the KTM mod now.. I feel like It could probably use maybe 2-3 more loops cut off as 4 loops increased the sliping from 20mph engagement to 25ish.. I really want it to slip all the way to 30mph as thats where my pipe starts to really hit..

So it is an expensive ass clutch and I only purchased it because I have had terrible experience with the three shoe clutches since I ride up steep hills everyday.. I need a clutch that will last longer and I really believe this may be the answer to the hill climb effort..

So my next steps are to get better gear oil so there is less of a difference to cold start and warmed up.. It performs where i want it when its cold so I am going to see if SAE30 works as I read that should help with the consistency.. Also I am purchasing a 13t front sprocket and a tomos clutch spring to do some more tests.. I think I could easily go down to a 13t but i'll loose more top end.. so right now I am going to mess with a tomos clutch spring and see if i cant get this thing to engage even later.. this way I still have the original spring that now engages at 25 and possibly another later engaging spring.. hope this helps clear up the bs about this clutch.. it works and has lots of potential imo.. id say if your looking for reliability this might be a simple answer..

get a three shoe. get two 2 shoe clutches, take off the 4 shoes, make them small so they fit a three shoe. get a clutch brace and kickstart springs.

REV FOR DAYS AND THE CLUTCH WILL LAST FOREVER!

Re: puch mk racing performance E50 clutch -TEST-

did that on a gila i had and 10 months later pads look new

Corn got a good idea. If you got to down gear that much for the clutch to work what good is it. I tune a 2 shoe with thick springs and with a Cheep 70 cc kit, small carb and 16x40 gears I could get the front wheel up. I got to sit on the back of the seat but still very good take off

Re: puch mk racing performance E50 clutch -TEST-

I wonder if my ss springs will help this rev harder.

Re: puch mk racing performance E50 clutch -TEST-

see i am warping braced clutches.. it has nothing to do with the tuning of the clutch.. i am heavy on a heavy ped.. with a bike that revz past 8k climning steep ass San Francisco hills.. my clutches last days not months... the pads look fine.. its the posts and even the plates warp.. the brace holes get ovalized... so from my experience I have only had luck with the ktm clutch though starting was a bitch... looks like this clutch is solid and should stay that way.. i like it..

what kind of brace are you using? what kind of bolts are you holding it on with? i was spinning 13,750 rpm and engaging at 7,500 rpm. post up photos.

I have always been using the atomic braced clutch.. I have used the stock screws that come with it.. i also tried counter sinking the screws one time because the earlier versions used to scrape the bell housing.. I understand that most people have zero problems with the 3 shoes and two shoes clutches.. I also have zero problems with them when I am in the flats or moderate hills.. also if they are on a lighter bike like a maxi with lower gearing I also have zero problems.. the problem starts to happen when I use them on heavily modified setups.. I start to warp out the clutches because I blast up steep hills and they slip more at that time causing them to slightly ovalize the holes in the clutch brace making the metal parts of the arms drag on the bell at idle.. in other words major off the line lag and shitty run up time to the pipe before i climb a major hill.. im talking like a mile long steep hill here and I need reliability so im not fucking pushing my moped up half the fucking hill.. the only ped I had that would blast 60mph up a hill was a polini that was ported by Elliot Ortiz and the two shoe clutch was perfectly tuned.. though it took two long blocks for the pipe to hit.. in my case with traffic lights that is a huge risk since running them could be death by cross traffic..

that sounds about right, i just haven't heard of the braces ovaling if you counter sink them.

thanks for testing out this clutch. someone needed to do it. take lots of photos.

you should get a pipe with a lower RPM powerband, and dont have your clutches slip so much. That would solve the hill issue too, as youd be in your powerband going up hills and not slipping the fuck out of your clutch and warping it and so forth.

Re: puch mk racing performance E50 clutch -TEST-

good testing. keep going.

Re: puch mk racing performance E50 clutch -TEST-

yeah proma circuits are great for hills.. but top end would get down to 40-45... i kinda like hitting 50mph.. im gonna see if this MK clutch lets me climb hills with mad slip and still hit 50+.. since it has so much surface area it should potentially last much longer then the dinky stock puch pads..

Re: puch mk racing performance E50 clutch -TEST-

clutched used to last me only a week or so. now they last years! I moved from the mountains of maine to the coastal plain of south carolina!

cool I used to live in a forest..

Where I live I only got 2 hills like San Francisco

I can't imagine a city with hills like that.

I got to go there sometime soon

Re: puch mk racing performance E50 clutch -TEST-

just tried to climb bosworth but the roads were way to wet for my michelen tires.. fuck they suck in the rain.. had to push it up diamond street.. mf

Re: puch mk racing performance E50 clutch -TEST-

but so far as the test goes.. 30SAE did improve the overall performance when hot... not a ton but enough to notice..

this is still with the stock modified spring.. have yet to test the tomos spring i got earlier.. going to snip 3/4" off of it..

Re: puch mk racing performance E50 clutch -TEST-

If having slip issues, try "MOTOR HONEY"

Re: puch mk racing performance E50 clutch -TEST-

those clutches arent designed for slipping... they are for the track. "race clutch". im so amped to get one of these... some dude on ebay had a ton for 120 shipped from the nl... i missed out...

Re: puch mk racing performance E50 clutch -TEST-

More on this subject.

Re: puch mk racing performance E50 clutch -TEST-

still on ebay.

Re: puch mk racing performance E50 clutch -TEST-

So I tried out a tomos spring cut about 3/4 of an inch off and it worked much better.. I would however think cutting an inch or more off would be perfect.. so my test concludes that this clutch is solid.. just buy a few of the tomos springs on treats and cut them down and experiment.. its pretty easy to adjust since you dont need to take the clutch off the shaft.. anyways.. i blew up my kit.. ring caught a window so im moving onto my za50.. i'll kit this e50 out with a cheap kstar or maybe i'll gila it someday.. lol

Re: puch mk racing performance E50 clutch -TEST-

Did you have it installed in a kick start e50 or a normal one. Sorry if this was.already stated. Any issues with the starter plate?

Re: puch mk racing performance E50 clutch -TEST-

Bump. Also, what kinda oil are you using?

So you went Kabooom Klunka klunka in just 15 days,

Re: puch mk racing performance E50 clutch -TEST-

wayne the kit caught a ring due to my rear wheel bearing exploding while riding.. I did not build the rear wheel nor did i build the engine.. one of the guys at treats built the bike.. so you can suck it wayne..

Re: puch mk racing performance E50 clutch -TEST-

#CrazyWayne™ rocks. #CrazyWayne /

What dos that have to do with you over revving it till the rings fluted and broke?

But the clutch is ok right?

I wanted to see just how much abuse that clutch can take & for how long it can take it!

If it can last you 7 or 8 Kit & crank blow ups i will buy one.

So get with it and blow some shit up!

P.S.

Don't forget to post carnage pic's.

And i love you to...........

Re: puch mk racing performance E50 clutch -TEST-

???

normally i think telling wayne to "suck it" is funny. but what the fuck does your rear wheel bearing have to do with catching a ring? isnt that like saying "my exhaust came loose and it blew my headlight and wayne can suck it."?

anyway, sorry to hear about the kit. how did the clutch perform while hot vs. cold? notice any difference? it looks like it would generate a lot more heat and maybe mess with the slipping properties of the trans oil more because of it.

Re: puch mk racing performance E50 clutch -TEST-

So the bottom line is Treats Reed Kit+14X42@50+MPH=12+K=Kabooom klunkl kulanka.

It's good that your letting others know not to do the same.
