Rattler with some BITE!

We've been long awaiting a performance exhaust for the Rattler Buck-Ten and we've finally got them IN-STOCK.

We couldn't wait for the snow to melt, as soon as they showed up we snagged the OEM pipe off our Demo Rattler and Installed the following items:

1000 RPM Clutch Compression Sping (this allows the RPMs to go higher before engaging the clutch)
Prima Expansion Chamber Exhaust
85 Main jet
We left the stock rollers in just to see what would happen.

YEEE HAW!!!

You have to be careful when you give it full throttle as the front end can now wheelie without any trouble at all. Accelleration is fantastic. We have yet to put it head-to-head with a Buddy 125 yet, but we knew the top speed indicated on our Rattler was 61 mph before the mod and now we're getting 66 mph with no trouble getting there. We know we could get more with a little more time sorting the variator weights and jetting, but it's °25 out there and all jetting now will go out the window once it warms up.

If you have a Rattler - Call us IMMEDIATELY! We have the complete kits in stock and ready to go.

If you were thinking about a Rattler - Call your dealer IMMEDIATELY!

Narrowed bars? Did you narrow the stock ones or did you swap to someting else--and, if so, what?

We narrowed the stock bars by about 1.5" on each side. The OEM bars on the Rattler were great (if it was a 900cc supermotard) but it felt like overkill on a 200 lb. scooter. The bar ends that come with the Rattler are threaded and so is the I.D. of the handlebars. We simply used a tap to cut new threads into the handlebars and replaced the bar ends as OEM. The bike looks cleaner with the more narrow bars and it helps when lane splitting / getting through doorways etc.

This is something your scooter shop should be able to knock out in under an hour. Definitely worth the time spent. BTW aftermarket bar ends will probably NOT fit into these bars, we tried a few of the "expanding rubber" kind and the I.D. of the bar was too narrow to even get the nut through. Tapping is definitely the route to take.

Phil,

Would you please pm or email me regarding pricing and jetting for 400-800' asl.

Thanks,
Sieg

I actually want to change my bars to a higher rise. Occasionally the stock bars will hit my knees at full lock.

A local guy has done this (on a pre-Rattler PMX) so I'm going to talk to him and find out which bar he went with.

Phil--thanks for posting this. That's a pretty sweet ride.

Phil,

One more thing..........is your airbox in the stock configuration?

The stock air inlet size, paper filter, and foam pre-filter, leaves room for a somewhat substancial increase air flow.

Thanks,

Sieg

I'm going to be out of town until the 4th of Jan, but I recommend going up 2 points on the main and leaving the airbox stock (so far) as we keep tinkering with it we'll keep you posted. Or, since we're up to our ass in snow, maybe if you come up with something that works, pass it along. I hesitate to publish any tuning tips that I come up with in the winter as it all goes out the window once it's back above freezing.

Bar risers may be the simplest route.

pocphil,

Have you had chance to experiment with the jetting yet?
