Pug clutch vario vs clutch pulley

Scottee doesn't know. /

got myself a frenchy boi.

preferences of a clutched variator vs clutched pulley?

Re: Pug clutch vario vs clutch pulley

Clutch pully is 10x better

Re: Pug clutch vario vs clutch pulley

The pug vario clutch is actually pretty good, it can be tuned and has a nice engagement. It's great for stock and even your middle of the road kitted builds.

The clutch pulley is much more aggressive, it takes a lot of work to make it really work well but once it's dialed in it will let you rip on screamer high rpm ripper setups.

Usually if you have to ask, you will want to run the stock setup. There is plenty of info on stock vario tuning including a really good thread that just got bumped. If you really build to the next level you will know when it's time.

Was kind leaning toward a H20 build.

Just figured if there was a bike to do it on this is it.

French problems and all.

I'll find the thread and check it out.

Re: Pug clutch vario vs clutch pulley

If your interested in making a fast 50cc motor the clutch pulley is really your only avenue to bottom end, however I have found them unneeded for the most part when going 70cc's. As Graham said, the stock vario tuned is very nice, but the ER3 or the Malossi Multivar are fantastic with a stock pulley

ya i wanna walk that line of reliable and fast.

unneeded becuase 70cc has enough power to satisfy lowend with out some 8k stall?

(ive been keeping tabs on the thread about the er86 pulley stall point)

right now the cart is loaded with a 50cc h20.

but if by chance the polini fairy shows up and delivers the 70cc h20 before the trigger gets pulled. i take re-evaluate and go clutch/vario isntead of clutch/pulley

thanks for the advise.

If your going 50cc's your gonna want a pully for sure, its the real ticket to get bottom end outta them

Re: Pug clutch vario vs clutch pulley

In my experience walking that line means airsal 46 smallport kit detuned with lower compression and backed off timing. Still plenty of power but it won't over heat and you can use a stock vario and clutch no probs with good accel. I think the malossi iron is also well liked, people even say polini w is good but maybe more overheating risk? I don't know I haven't run the latter two. The small port airsal matches to euro stock cases, pretty much anything else is higher rpm and needs a lot of porting with new cases.

You can run the simonini for a nice midrange blaster, or there might be other pipes I'm not familiar with, but even a stock pipe will do pretty solid mid 40, albeit not a rocket ship getting there.

Re: Pug clutch vario vs clutch pulley

Yes to what graham says that the stock vario clutch is ok for stock and middle of the road builds. Where it begins to suffer is when you start adding pipes and really twisting the RPMS up tight,

The components begin to fail in three ways. First the composite clutch disc crack and break from excessive RPM or the locking ears start to shear off the disc from mods to the weights in the variators engagement point or the removing of more than two thrust balls from the thrust plate to delay engagement and gain initial higher RPM at take off.

Another way the stock variator clutch well fail from performance mods is that the higher RPM stresses the clutch locking ring and causes it to snap followed by the shearing off of all the clutch disc ears. This is especially prone to happen when the builder has removed the primary starter clutch shoes to once again gain that sweet sweet clutch slip off the line .

I have in the past built in some extra support post on the locking ring to help keep the locking ring from warping and snapping due to the empty space left by the missing starter shoes. It worked good for a long time but eventually snapped.

The third week link is the the clutch bells center double"D" hole that locks onto the crank shaft. Variator mod and high RPM Wheelie engagement will cause the center of the bell to "round out" or to snap the center out completely.

I have read on here that people have had success avoiding the "rounding out" by tack welding the double"D" washer to the clutch bell as it gives it double the surface area connecting to the crankshaft.

That method is great but it wont help when the cent decides to just snap out. It's all going to go.

Re: Pug clutch vario vs clutch pulley

Yes to all the previous posters. If your going to go with a pipe and high RPM twister kits you will save down time and money by investing in the ER3 variator married to a clutch pulley kit

Re: Pug clutch vario vs clutch pulley

This is a great info. Hopefully anyone else can use for info down the line.

I ended up with a

Doppler 50cc h20

Polini race case party

Artek crank

Er3

Clutch pulley.

Cdi

Etc etc

It might a solid step into the ripper category.

Rad mount is likely going to be my next issue to resolve.

Re: Pug clutch vario vs clutch pulley

go slow and jet fat. That set is going to twist tighter that a dicks hatband.

Re: Pug clutch vario vs clutch pulley

Thats a great looking platform bike. Attention to detail will also help your sucsess

Re: Pug clutch vario vs clutch pulley

do you want to sell your old variator stuff? I need a new locking ring for mine ha ha.

Not kidding.

Re: Pug clutch vario vs clutch pulley

Ya. Easier said than done. My hype level is up there.

Thanks for help. I'm sure I'll be asking for more.

Re: Pug clutch vario vs clutch pulley

Let me feel semi confident in this thing. Then I can let.gonoff take off parts ?

Re: Pug clutch vario vs clutch pulley

There are some good posts on radiator options, Andy scouten has posted some you tube vids as well that walk through a H2O setup. Just make sure you get all the air out of the system before you start giving it the beans.

If you keep the timing low and run heavy weights to start with, it will give you a lot more margin for error as you tune. Worst thing you can do is high timing, air leak (or rings not seated) and high rpm with no load. Running heavy weights will keep the engine from wanging up to a million rpm while you're still trying to figure everything out.
