Rev Limiter

[txblueshee]

or bigger carbs, or porting, or air filter, or reeds, or timing, or compression.

 

I thought the quote button would've grabbed benbb's post too... That post was more directed to the dyna cdi setup...

I've never heard of an actual rev-limiter on a Banshee, but the T.O.R.S. supposedly is a Throttle Override System for when the slides (or as the book calls them throttle valves(what ever the hell those are)) get stuck open (ie full throttle) and are supposed to shut the motor down. But then again I've never heard of them doing that either.

 

Cometo think of it, I think Yamaha put the TORS on our Shee's just to cause electrical problems when there is absolutely no other problems on the bike......... :yelrotflmao:

i was behind a baja 650 sunday at top speed, since i was in his draft i kinda leveled out with him but it did feel like i hit a rev limiter or something because it was cutting out, and oh yeah it is a 100% bone stock banshee

[firefighterjosh]

Banshee's don't have rev limiters. Every 2-stroke I know of does not a have a rev limiter. They rev till they blow.

I guess i'll just have to get those things done :laugh:

The rev limiter hits somewhere between WOT and "BANG"... :tongue: Seems like every time I ride I test out weather or not my bike has a "limiter", and I havn't found it yet :shrug: :yelrotflmao:

BenBB is right. There is no limiter. Most builders don't run past 12,000 to 12,500 on a banshee based motor. There is such a thing as a launch limiter, but is aftermarket. Helps the motor to get traction out of the whole and then stops limiting RPM.

That crappy TORS only works if the slides/cables physically get stuck. Get a real bad lean condition via airleak or whatever and it'll still rev till it blows. TORS won't save u.

 

 

 

Oh yea. I agree there's no rev limiter on the shee.

BTW last time I looked at Dynas, when I got one, I don't remember any mention of increasing RPM's; on 4-chokes yes, they have 'em, but not Banshees...

 

No 2 stroke has a limiter...

SRP makes a CDI rev box that claims to give you 1000 more RPM....it's a marketing ploy BS.

 

The pipes and porting configuration dictates how far the motor can rev...

Valve train is the reason for rev-limiters for the 4 pokes...

 

I know on the 450R...if you up the rev limiter without better valve springs, you'll float 'em....

That is the one thing I can not get used to on a 4poke...timing my shifts just before the limiter hits.

On the shees, you just shift as soon as it stops pulling....oh well.

Nope, no rev limiter, I actually never knew most 2 strokes never had rev limiters. Check http://www.dfn.com/benkaren/elecfaq.html

 

Banshee CDI's have NO rev limiter, as some 2-strokes and most 4-stroke CDI's have, that will cut out the ignition or otherwise prevent the motor from exceeding a preset RPM.

Maybe i should tell my friend with an 06 450ER to not fiddle with his quad. He says that when you get the HRC kit or whatever..to raise and extra 1000 RPM you just have to cut a green wire. So maybe ill tell him that he shouldn't cause his valve's can't handle it...orr let it blow up :shrug: :laugh:

My buddy has the 04, which is a different motor. The 06 is actually the same motor as the CRF dropped in a quad frame...so, not sure if that's true for 06.

I was talking to him about it and he says its only for teh 06/07's. But i dont care its a 4 stroke :laugh:

 

I was also wondering if you guys know how high your are revving just cruising or climbing hills, etc. Like a general area that is good and you run it this hard all the time.

[Skidmark]

It's not really what you would call a "rev limiter" but at the same time it is. It's just like what a couple people said on here already, it just revs up as high as it can go. All motors have different "rev limiters" depending on mods. One could be 10,000 another could be 10,500 or anywhere inbetween. When you miss a shift it revs to an extent and just stays there so its either something electrical like the stator or the motor just cant get anymore rpm's. Get what I'm sayin? :baseball_wassat:

[dajogejr]

It's not an electrical limitation.... The motor can't spin any faster due to port layout, pipes and intake...

 

So, if you want to call the engine's inability to rev any further a rev limiter, then...uh...ok.

 

As compared to a four stroke where the ignition cuts when it gets to redline....
