Dr Pulley 20x12 14GR

[Cortez]

Hi Cortez,

Something that you may want to check first is if your scooter comes with the new variator (the ramps are slightly shorter than the older model) alose the old variator is labeled as LEA7 and the new one as LGE5, which is exactly the same that they are using on the Peoples GT300i.

If it comes with the new variator I would go for the 15g, I had the 14g on mine (with the new variator) and it didn't feel right (too agresive) I kept them for 2 months and changed them to the 15g which make the bike a bit more relaxed when compared to the 14g.

It will be interesting to see your fuel consumption, most guys in the USA get well over 70 mpg, I can only hit the low 60s.

Yeah, thanks, will check, is that printed somewhere on the CVT itself or can I check somewhere else?
It should be the older model, it's a last year bike!

You got 15g Dr Pulley sliders?
Can you confirm any of the stuff we talked about here (revs at full throttle from standing still, cruising revs
at 50, 60, 70, 80mph, anything like that)?

You don't by any chance remember any of that with the 14g weights?

I've made a fuelly account, will make a signature line with it as soon as the bike gets here.

Just got an email from Paul (the DrPulley guy!), and he's more then aware of the CVT difference in the
new and older Downtown but he didn't recommend anything specifically for any of the two.

I just found a video on youtube of a guy who says he's got a stock bike, and it revs to 6500 on WOT,
so that might be the new CVT setup, and obvisouly exactly what the 14gr sliders would do in the old
CVT.

I'll just have to wait and see which one I get, since obviously the newer CVT type would be better
with 15gr sliders.

Great way to make things complicated.

I think my readings will not be that helpful as I have installed the Dr. Pulley clutch and I noticed a change of rpm againts km/h straight away. In short the scooter needs more rpm to pull away and slightly less for top end speed.

If you want more details let me know but not sure how useful they will be.

In regards to your variator the only way to tell is by looking at the variator itself, it is printed on the ramps for the rollers , however if I am not mistaken if you go by the model number any Downtown stamped with SK60A (on the engine cover easy to access/read) and onwards should come with the new variator. I bought mine at the end of May last year and was one of the first to come with the different variator and clutch.

Thanks!
This is an older scoot probably, so I guess I'll get the old CVT! No biggie as I've just found a source for 14gr sliders that'll ship to me.
The clutch messes things up so yeah, that probably won't help, but I'd still like to hear about it.. since I've heard great things about the HiT clutch.
 

[juanpauk]

, yes the Clutch is fantastic, I had the vibration, slippage and noise with the stock one when pulling off and when on traffic, but now that is past!!!
The HiT clutch is great it takes a bit longer to engage with the bell, but once they touch they stick together no messing about. I had it installed last week so I want to give it more time to settle along with the rollers and sliding pieces.

So far I can notice that the bike requires about 700 to 1000 rpm more to pull off, top end speed has increased by at least 5 km/h not a lot but noticeable nonetheless. My riding style is not aggressive so the default spring setup suits my needs (smoothness all over), the clutch comes with 2 x 4 sets of springs (pillows and clutch) to test with and modify the clutch depending on your taste and needs.

With the naked eye you can tell the product is of high quality, starting with the shoe pads the material looks and feels tuff, perfect for its function (to engage without slipping ).

I had it installed 5 days ago and it is still early days to draw to a conclusion all I can say is that so far that the money was well spent and that I am enjoying my scooter as much as I did the day I rode it for the 1st time.

I will give you  a better review after a couple of weeks, with some readings...

[Cortez]

Great!
Thanks!

Make sure you open up a new thread about it, I'll buy probably buy one in the summer.. could use
the rev vs speed info with the setup you got!

Dear Members. then accompany them to post that I published entirely in Spanish forum that may appeal to this thread:

Dear friends, today I discovered indirectly through an open thread juanpuak the American forum, that from January 2011 references to parts of the drive have changed, because the drive as a whole is quite different from the Model 32 cv with respect to the 29-hp, it also evidenced some videos uploaded by juanpuak where you can see the remarkable difference, it is as if we bring you a series production Malossi, confirmed by the end of this motoring magazines commenting that the differences of a model and another were also improvements in the transmission assembly. Now I understand why there is so much difference in performance between the 29-hp, not included in juanpuak, the date of purchase and is already incorporated the new drive and clutch, as I said, now I sense that those who have had a passing 29 hp to 32 hp, less noticeable difference scooter. Am I at risk of being wrong to claim that juanpuak socooter of as fast as ours and that tells me is able to tell the difference lying scoundrel, for that reason those who carry the E000 not be able to notice the difference these 3hp, because I remain convinced that this unit is of 29 hp. improved weight / horse is only 0.61 kg / hp.

References that change in the drive:
Plate which houses the roller: LGE5
where are the movable hood: LGE5
Bushing (which atrviesa drive: LGF9-E00
All other things being equal, the rollers are the same, so we think that Dr, Pulley served it safe and I agree with juanpuak again, I think the rollers 14 gr with this drive will not well go best with the 15 gr.

References that change in the clutch:
Shoes: LGE5
Mobile Dish: LGE5
Plato Primary: LGE5
The hood and contrast the springs and spring are maintained, which is why the bell Malossi juanpuak serves.

Once exposed this that each draw their own conclusions.

Found him already, thanks, I think I'll deal with buggypartsnw.com if I'm gonna need 14gr, and that guy above if I need 15.
We'll see, the bike should be here on tuesday.

[Cortez]

Ok! The bike is here, and I've got some 60 miles (in rain..) on the ODO!
 

However!
I have no idea which variator type I got in the end, since I got some different
numbers then both versions reported here. I guess.

The 2011 test bike I had for the weekend was the same as TANWare's, would
sometimes hit 6000rpms at WOT, and would cruise at some 62mph at 6000rpms.

I've tried WOT 3-4 times up to 60-62mph and I get around 6500 revs up to about
50mph, and then it drops to maybe 6100-6200. There's a slight flat spot between
60 and 70mph and then it starts pulling again. I haven't done over 70mph yet.

At 62mph (100km/h), the revs are at 5500rpm dead, and I was expecting 6000.
Tried it a few times too. Just a tiny variation.. but no more then 5600.

At 6000rpms I get around 68mph (110km/h).

Should I expect any changes in the revs vs speed with time?
Maybe I got the newer variator after all, even if my bike is actually the older
model (no hazard light switch).

Looks like I'll be looking for 15gr pulleys after all.
Can anyone with the newer variator confirm their revs at 60 or 70mph?

Thanks everyone.

[TANWare]

mine takes a short climb with stock rollers above 6,000 RPM but settled there abouts at WOT till speed got where it allowed further. I noticed at speed the RPM's went up at bit. As time goes on the the 23mm gets worn the rpms will climb slightly as well.

Even with the DR Pulleys at first it goes up slightly higher than 6,500 RPM but then quickly settles there...................

I'll try again today, but seems like mine will
do 6500 at WOT..

That's a huge difference in acceleration compared to the last years test bike that did 5600-5700 at WOT.

Lemme just confirm - you had 6000 on the tach at 60-62 right?

[TANWare]

no 5,600 or so....................

[Cortez]

Oh.
That's interesting. Then I have the old variator as suspected.
The test bike I had showed 6000rpm at 62mph.

Here's a quick video:

[Cortez]

TANWare, now I see what you've been talking about about 50mph roll-on.. being two-up today,
me and my friend are about 450lbs total, the scoot would hit a wall at around 55-60mph and lock itself
around 5600rpms and it took probably over 20 seconds to get from 60 to 70mph it would barely pull!

After 70mph and over 6000rpms it was a bit better, but knowing the available power is there and not
being able to use it is a pain.

Didn't ride too much, I've got a cold and have been working through the weekend, but I think I'm pretty much
decided to go with 14gr sliders even if I love the low revs cruising around town at 35-40. I can live with 200-300
more.

If I understood correctly, at a given constant.. let's say 55mph and 5500rpms that I have now.. WOT would kick
the revs up to 6500 with 14gr sliders or.. ? Because when at speed, and around the 5500rpm range (50-60mph)
the WOT would not shoot the revs past the mark they're already at, and the bike will not accelerate as fast between
50 and 70mph as it would if I gave it WOT from zero at the lights, for example.

THEN it would shoot to 6500.. drop a bit, probably to around 6000 at 60mph but never under that.
The difference in power between 5500 and 6500 rpms on this engine is amazing.

At 5500 it feels just like any other 250cc/20hp scoot.
