can anyone explain why my big ruckus is nowhere as quick as my helix?

Hey everyone,

I happen to be in a very fortunate situation where I have two awesome scooters. Both are entirely stock. The helix is an '06 I believe and only has 700 miles on it and the Big Ruckus is an '05 model with about 7k miles on it. Both have been maintained and are in great mechanical condition. My Helix gets around 50 mpg and the Ruck gets 70 mpg so I'm guessing it has something to do with fuel jets or carb differences. Is there a way to get my Ruck up to the speed(acceleration) of the Helix? My wife usually rides the helix and I hate seeing her pull away from me. lol. Just curious if there are any options out there to get it up to speed without spending a lot of $$$$. Thanks.

Interesting; because my BigRuck only gets about 60 mpg. Although I'm similarly disappointed with the speed.

I'm guessing the lack of any fairing to slip through the airstream has something to do with it. But why there should be such a variance with models with the same engine/carb, is a mystery.

The Big Ruckus comes stock with six 26G Roller weights, too heavy for the engine to quickly spool up and give decent acceleration. The Helix comes stock with six 23G roller weights, when you gas it the engine spools right up and gets with the program. The Honda Reflex uses a different type stepped variator and uses three 21G weights and three heavier weights giving a different response. Just buy 2 sets of Honda Reflex rollers, install three of the 21G weights from each set and you'll think it is a different Scooter. Quite a difference accelerating up hills as well. It's like a $40 mod but Scooter remains Honda OEM, there is a simple variator holding tool to build and you'll need a torque wrench.

I ve read the K mod which is what you talking about isn't recommed on the big R at total ruckus.

Best mod!

On my big ruckus, three simple mods.

21g Dr. Pulley sliders $30
*use the stock variator and these sliders = awesome

Blue Polini Contra Spring $20
*this spring goes between your clutch and rear pulley. It helps hold low gear longer off the line and snaps back to low gear faster on hills.

REJET $5
*toto a 45 slow jet and 102 main. Easy mod, don't even need to take the carb out. Just pull the left cover and turn the carb.

Do these nods and hold on..... its like you added 100cc to the engine. I have been running this setup for about 8000 moles now. Top speed still 75mph+

Both are 250cc, but I'm pretty sure they aren't the same engine. The Helix engine is virtually the same as the Elite 250, except on the Elite the engine is upright. I believe the Big Ruck uses the same engine as the Reflex.

It;s a reflex engine with all the anti pollution ship that comes with newer bikes. It's comparing lemons to orgages. Different designs. Even down to how the wind effect your speed. Ruckus has far more wind drag compared to a helix. Even diffenent gearing on the tranny.

The 1985-88 Elite 250 had a vertical cylinder and 244cc displacement, the 1989-90 Elite had a horizontal cylinder and 249cc displacement as do the Reflex and Big Ruckus.
They may not be exactly the same engine but the 249cc versions are closely related.
I wasn't suggesting Lee do the Reflex K-mod at all, just acquire six 21G Reflex rollers (you will need to buy 2 new sets of Reflex rollers to arrive at that amount) and swap the six 26G Big Ruckus rollers for the six 21G Reflex rollers. With the other six heavier unused Reflex rollers, the core can be pressed out and drilled so a custom set of 20G or 22G rollers can be made.
I've not rejetted mine (yet), but those who have report good results.

just thought I'ld post up and update. With much help from Kev187 I have ordered the jets for the carb, rollers, and spring. I hope to maybe receive everything next week and get it installed. I'll be sure to post up any problems and results. Thanks!!!!!!!

I think it's a shame that you have to pay for after market parts and the time and or money to have them installed, just to make your 250cc scooter perform like most other 250 scooters.

yeah that may be true but I've had LOTS of m/c's over the years and I can honestly say the ruck will NEVER be sold no matter what. I can't explain it but it's just so perfect for me that a $100 cost of parts is worth it to give it a little more pep for around time. I'm planning on doing the install myself but may have to call a lifeline if I have trouble. :loll
