View Full Version : lack of power ?
hi i rode my friends k3 pointy and feel that its a lot more aggressive for example doing power wheelies in 1st his lifts up straightaway compared to my k6 which is abit reluctant
not sure if its worth mentioning his has a niko g pack (not sure exactly what it does it came with his bike)
are there any differences or reasons for this
your friend may have a naked chain and sprocket set up.

I think i remember reading a niko g pack just eliminates timing retardation in 2nd and 3rd gears so wouldn't explain your first gear observation.
A K3 must have had a chain and sprocket change by now. Did you count the teeth on front and back sprockets? It is the most obvious explaination!
K3's are different to all other K bikes. Different subframes and swingarm too.

It does sound like the gearing has been altered. Nikko G pack is just £100 wasted when you could cut two wires and still not really notice anything happening.

Not quite that simple, a resistor is required for a pointy, but all that is retarded is the valve timing below 4000rpm and under half throttle. If you're opening the throttle more than half way, it'll have no effect whatsover.
well my friend has done a sprocket and chain change on it and replaced with oem sizes.
need to check mine but I'm quite sure it's still the same one from factory
OEM isn't that simple either. For an SK3 it's 15/44 - for the naked it's 15/45.
However they changed the S to the same gearing as the naked for later models - no idea which year they did this.
So when you buy a new chain and sprockets, if you pick by model, it's anyone's guess which one you'll end up with.
The last time a dealer changed my chain and sprockets they fitted something utterly non-standard like 16/47 and never told me.

It is entirely possible that your mates bike is just another example of why the K3 is just so nice. There are so many possible variables here, is the air filter in better condition or the exhaust more open on his bike, was his bike recently serviced, his chain better maintained, were you less careful on your mates bike than with your own? I find that on cooler dry days, my engine runs better than on warmer damp days, maybe you had a day like this.
On another note, maybe your own bike needs a good service, the TPS adjusting and the chain given a good clean and lubricate? When you last serviced your bike, did you check throttle balance and throttle cable tension?
When I adjusted the TPS on my K3 the difference was immediate, from a slightly unsteady grumble before to an impressive raw after.
So go and have a look at your bike and think about making it healthy and lovely again. ;-)
I read somewhere that power wheelies are apparently easier if you deflate the rear tyre somewhat.
So check his tyre pressures!
well my bike has literally just been serviced. also the chain was just clean and lubed prior to going out ☺
he does have a sp engineering gp can on his and mine has a fuel can.
I'm looking to also get an sp soon

Wheelies are naughty and I never ever do them... :smt077
Bare in mind though that they are not good for your head race bearings and I am sure that I read some where on here that they cause oil starvation to the front cylinder... but it can't hurt for a couple of seconds surely? :mrgreen:

In that case the answer is simple, you hate his bike more and were mean to it! :smt040
no I think if your doing mile long it might be bad for oil starvation but short ones aren't bad. my friend manages to clutch it and holds it for about 10 sec and it's always been fine

Haha.
p.s an one want to swap a fuel can :)
Before jumping into changing bits on your bike, I doubt the can would make much difference at all. Could you try fitting his can on your bike?
Does he have a different throttle? Fitting an R6 throttle tube with a 1/5 turn instead of the stock 1/4 was a common mod a while ago.
I'd imagine suspension would make a difference as well - has he changed his rear shock? It might even be knackered, which might make it easier to loft the front. Or just set differently.
Compare the chain adjuster marks. If his chain is new and yours is worn, he'll have a shorter wheelbase, which might also make a difference.
Oh and fuel level. If your tank's full, you could be carrying an extra 12kg at the front, compared to an almost empty one.

Sounds to me this could just be a case of a worn engine vs a not so worn engine!.
