Who has an RB carb AND a FWW ??

Post by KDXer »

Just curious as to whether a FWW has any effect on the performance when dialed onto the SSS. So who has one of Rons carbs be it modified stocker or an Air Striker and is also using a FWW ?? If you ARE using a FWW, what size is it ??

Cheers...

Not sure how heavy mine is, it is a Steahly, it was on the bike when I bought it.

Don't have a FWW but I'm keeping my mind open . . . if you get one, Trev, give us a really good opine on it.

Is there more than one size? I've only seen the Steahly (10 oz I think), are there others commercially available for our green sweethearts?

My 220 doesn't have the carb mod, but has aftermarket reeds, head mods and a rev pipe. The flywheel weight was a plus when just the pipe was installed, let alone the other stuff. Frankly, I could use even more mass on the crank than what the sheahly provides, especially when riding in the dry season on slippery trails.

That I don't know, I haven't researched into it THAT far as of yet. Just wondering outloud if any/what effect the FWW or even the DEK vs CEK has when dialing in/searching for the SSS. Still not convinced I have found it. I'm at 2.75 on the A/S and it will crawl up a gnarly hill very slow in 3rd gear (sounds like its four stroking) but sometimes has the tendency to stall unless I downshift (crap description, I know). Not sure if I am there or not. :?

see now I don't understand why you would try to climb a hill like that. I'm sure it's because I"m a non-RB'er, but if i wanted to tackle a gnarly hill, I'd be screaming my way up, maybe even fanning the clutch.

To me "screaming" = wheelspin, and loss of control

Sure you might make it but you are pretty much f'n the trail up for the next guy

With the SSS you can tackle a hill with little or no wheelspin, and you can pick and choose your line

The trick to technical hill climbing or steep trail navigation with any kind of bike is momentum, IMO. Some places you will need to back off the throttle and still be able to carry your speed over obstacles, so you want keep the rpms up high enough so as to be able stay in the same gear, if possible, when you power back on. Additional flywheel weight also keeps the engine spinning higher, longer during off-throttle situations. If you lose bike speed, you lose momentum - that's when people start to dig those irritating holes the rookies always leave to screw up the trails with. This even applies to powerful open-bore 4 strokes. Where I ride, summertime traction is mostly poor, the flywheel reduces wheelspin no matter where you are in the torque curve. Less wheelspin = more speed = more bike momentum for those places you need to coast over before hitting the gas again.

I can't imagine the specific torque characteristics of a particular engine mod, especially those attributed to carburation tuning, making that much difference as to whether a flywheel weight is warranted or not. If you don't have problems with excessive wheelspin with your riding style, power and riding location profile now, you probably won't benefit much from a FWW in terms of performance.

However, flywheel weight enhancement, much like viagra, also provides noticeable advantages if you have problems with stalling or other such... performance...uh.... shortcomings. :mrgreen:

Thanks for the reply. I am actually trying to work out whether the FWW changes where on the A/S the SSS is located, not whether I need one or not. :mrgreen:

One thing I did notice when searching for the SSS which caught me off gaurd was this....

<try to picture this> I was trying to get out of a gnarly, slippery, mossy, muddy creekbed. I had to go up a 10' high, steep slippery bank that had approximately a 1' high log, laying sideways and about half way up. As I approached the log in 2nd gear I gave it a little twist to get momentum up and get the front wheel over. I was expecting it to spin up the rear on the slippery mud/moss, clip the front wheel on the log enough to bounce the front over and get caught up on the log with the back wheel stuck and spinning....

BUT NOOOOOOO !!!! The ol' girl stood straight up on the back wheel and tractored up the bank (almost flipping). I hit the log still on the back wheel which LUCKILY made the front wheel slam back down to earth and somehow the rear got traction and I got over the slippery, mossy log like it wasn't even there. Another WTF moment.... :supz: :prayer:

Does that sound like a situation where the SSS gave me the unexpected traction over such slippery terrain ??

Please excuse the dribble, you can blame it on Tanqueray and OJ. It's been 1 year since I lost my best mate on his roadbike :cry: and have had a few :partyman: so I apologise.

No apologies necessary Trev. We're a big familly here after all and we all understand.
After reading your adventure over the log, I really can't wait for Ron's goodies to show up at my front door (today maybe :supz: )
