Are you RB'd?

Post by Indawoods »

This is a poll to find out who is RB'd, who isn't and who plans to this year.

What about the RB head mod? I believe we may need another poll.

Well you have some numbers, but how about what those people have to say about the mod and what they have, a 200 or a 220? I would be interested in their comments. I have considered the carb mod, but the thought of the divider plate possibly coming loose and entering the engine at high speed makes me nervous.

If you wanted, you could also do a poll on the V force reed valve.

There is no way it could come loose.

This section is for anyone wanting to run a poll question... not just me. :wink:

The way Ron has the divider plate installed it cant come loose. Even if it did the plate wouldnt pass through the cage/reeds because of the size and shape.

I picked up a 35mm carb for my 220 and got the A/S & Allen Bolt Screws (Thoses are great). I will be sending the carb in this winter for Ron to play with. A guy I ride w/had his done on his 200 and he loves it.

The 220 has a 33mm carb, 200 a 35mm carb. The 35 on the 220 gives it a bit more "umphf"
The 33mm is supposed to give the 220 the low - mid power its known for + porting.

The 200 and 220 both have Keihan PWK's. The 220's carby is 2mm smaller (33mm vs 35mm) and while that helps the low end on the 220 it really chokes off the top end. They both use the same carb and intake boots.

Who said you can't re-vote?

re: come loose

Can't happen.

If you are seriously concerned about it..don't be.

Well I'm not R&Bed mainly because I can't imagine getting any more from this engine than Iv'e allready got.(meaning a really noticible difference). (without going to larger bore,carb,exaust,ect.) If your atomazation/flow/mixture for a given engine is close to ideal can you really get more power/responce/speed without being able to move more fuel/air /exaust through your engine faster. (Not counting high compression race gas or nitro fuels).
So what I'm saying is past a certain ideal, if your not needing to go to larger and larger jets/carb/bore/exaust your not creating any more power/speed.
Just bury me when I can't ride anymore...

cmot - I've got a RB'd carb on my 89. Its a noticable difference expecially in the low end of things and something that I couldn't live without now that i've experienced it.

"your not creating any more power/speed"
I have noticed a MORE USEABLE POWER SPREAD and more top speed

re: 'because I can't imagine getting any more from this engine than Iv'e allready got.'

Yeah. What he said! I've thought the same thing myself...a couple of dozen times.

I always get something to imagine, tho...... :wink:

re: 'can you really get more power/responce/speed without being able to move more fuel/air /exaust through your engine..'

Take out the 'without' part, and you have the situation exactly described.

Do you honestly think the volumetric efficiency of your engine is 100%? Probably not. Not that THAT matters, 'cuz a 2-stroke that works does so at well over 100%.


There is no valid argument against the process...and that has nothing to do with anyone's particular choice in the matter.

You're WELCOME to ride whatever, setup HOWever.

Any argument against it to anyone who has it isn't likely to get you too far, though.

Cheers!

Not currently..a bit on the cold side. But I have used one. It was the correct choice at the time.
