Any word on the cylinder kit from SW?

DO3 · Post by **DO3** » Mon Mar 19, 2007 5:37 pm

Just wondering if any inside sources have heard anything about the rumored big bore kit from ScooterWorks?

I'm also wondering how much it would cost to buy a Blur 150 cylinder and piston. With the Buddy 125 stoke we'd end up with about 157cc. If the parts were cheap enough I'd think about buying them to see if they'd line up at all. I don't know how thick the cylinder wall of the 125 is but I would think boring it out 6mm would be impossible, since that's almost 1/4 inch. It would be a good project for next winter maybe.

I talked to my dealer this last Friday and he said that one of the guys from Genuine had just been on the phone with him and he said that a 177cc kit has been approved by the powers-that-be. No set date for release, though...

Schweeet! Thanks for the update.

is this kit actually coming from genuine? If so, since it's their product will the warranty still be valid?

If the Prima pipe voids it, I'd be very sure a cylinder kit would as well.

I understand that third party mods void the warranty but I was wondering if it's an actually Genuine product will it? (that is of course if it is a Genuine kit)

From what I understood, the cylinder kit will be a third party item. They were just being picky about who they dealt with, I think.

I think there's a "business relationship" between Prima, Genuine and ScooterWorks—as in the owner has some kind of stake in each. So you can bet Genuine is heavily involved in the development of the performance accessories.

But, yeah, it will void the warranty—at least its coverage of the engine. Honestly, even if it came branded as a Genuine product it probably still would. They can't control who/how they're installed, which could really screw things up.

ok that makes sense, thanks

While they are next door to each other and there are 'business relationships', aftermarket performance items are carried by Scooterworks even for dealers. You may not see this at the user end, but your dealer is not able to buy these performance items from Genuine directly.

any updates on the kit yet? Any Idea what price range it's going to be? Also is there Variator kit available yet?

Yes Genuine!!! I WANT MORE POWER!!!

Seriously, there is nothing more fun than riding my scoot, but it'd be even more fun if I could keep up with a few P200s I ride with. I wanna run with the big dogs!!

I'm actually surprised you can't keep up with the P200s... Their top speed is probably higher, but do you beat 'em off the line? Go go go CVT!

Actually, I can keep up with them all the way up to about 55 or so then I must tuck. Plus my main concern is rapping it full out for 30 minutes at a time. I figure no engine is built to run full out for that long. I mean look at how many blown engines there are in NASCAR.

Yes but nascar engines are 5.7 liters, running about 700 hp and our buddies are 125cc and probably about 10 hp max.

700/5.700= 123 hp/l

10/.125= 80 hp/l

They're pushing those engines a lot harder than we are. I'm sure there is plenty of safety factor built into the design of the PGO engines. From what I've seen overseas they run their small engines much harder than we do. I wouldn't worry too much about running flat out for too long.

Keys · Post by **Keys** » Fri Apr 06, 2007 10:55 pm

I've run flat out for, oh, a couple hundred miles at a time a few times. I intend to do it again soon. I regularly do it for about 50 miles at a time over the mountains into Prescott. So far, at 6000 miles, I've not had any problems. The anodized cylinder walls and pressurized lubrication system add a tremendous amount of durability to this little engine.

Hmmm. Susan's B125 is about as fast as my P200. It's definitely quicker off the line.

Plus, doesn't the Buddy have a limiter? I thought I read somewhere that it did.

I'm sure the manufacturer designed the governor to save the scooter from
those of us inclined to see if we can exceed the specified speeds.

If it does have a limiter, that will keep the Buddy from revs that will make the
engine blow or give out on an all day run.

Wouldn't the CVT prevent the engine from over-revving?

The continuously variable transmission certainly has an affect on speeds attainable, but I believe the engine has a limiter.

Nope. The CDI's rev limiter does that. Which means that without optimizing the CVT, you may not see an appreciable top speed from a cylinder kit, pipe, or another modification alone.

How would you go about doing that? Is that something the dealer would already be aware of when installing the kit?
