Instant revs!

**kunoichi** · 24th March 2009, 14:34

Hey guys,

I'v recently noticed that my kwaka ninja 250 2008 doesn't seem to gimme instant revs below 8000rpm. Is anybody else having this trouble? And anybody got hints as to wot to do with it? Ta

slack throttle cable?

dirty carbs/fuel injectors?

dirty plugs?

Isn't it only a parallel twin?? I'm not sure they're big on revving their rings out.

Yes its a parallel twin. They are quite revvy in comparison to the vtwins I hear. I havent ridden one, and I'm not familiar with this fault.

wonna describe this problem a bit more?

**Slyer** · 24th March 2009, 20:23

You mean there's a fair delay between twisting the throttle and getting a response?
What about in neutral?

Can you post a vid of what you mean or if it only happens when riding maybe explain it a bit more clearly??

Am I the only one doing this?

I'm keen for some instant revs if you guys figure out how to get them.

Direct Exhaust Injection (DEI) is the only way to go.

how instant is instant? is it bogging down? has it magically gotten slower over the weekend?

No it's been like this from the begining, and i thought it might of just been me needing to break the engine it. I have clocked over 7500Km now and after all the ATNR's, coro loop and northland loop, i consider my engine broken into. However this problem has not improved. Yes there is a delay between me twisting the throttle and getting a reaction, but only up until 8000rpm. Wen i'm sitting above 8000rpm she definatly gives me instant reaction and a great acceleration speed. I have no idea if this is normal or not, so i thought i'd ask.

I'll see if i can steal my sis's digital camera off her and record a vid for u guys this weekend. Cheers

Ninja 250's have all their power up high in the RPM range, the low-mid is quite bad. You will find this is common of all of them.
This might be worse than usual however.

Most bikes will not have instant acceleration when low down in the revs, especially the 250s.

Oh, i was just comparing my revs with that of my bf's bike, but yet again he's modified his bike. If its a normal thing, then mayb i'm just worrying about nothing
