KX500 power delivery ? how to make it longer ?

(1/3) > >>

davidvak:
After the negative adventure I had with the NL company ? POWER SEAL
I finally got to ride my beast with no worries. I went to an mx track where
I could open the gas wide as I want?. Loved the incredible torque !!!
I had CRF450 2003 which in my opinion was more aggressive in mid and
high rpm, but when comparing it to the bottom of the K5 the CRF feels like
a good 125 :-D . Any way, I find that my K5 is very short in his power delivery
, again incredible torque but when you get to the higher mid range it prefers
the next gear.
Any advice on how to make the power delivery a bit longer ?

hughes:
What gearing are your running? Stock is 14/47. Where do you what it to make power?

davidvak:
it is 15/48,  i have also complete FMF system. (fatty).

i would love to have it a bit higher , a bit longer then what it is now
and i am not talking about long gearing or shrort gearing but power delivery .

BigGreenMachine:
Go get yourself a GOOD quality midrange/top end port job with the airbox lid off or holesawed.

hughes:
Retard the timing. It will tame the hit but will give you more over rev at the higher rpm. Carbon fiber reeds work great at higher rpm they will not flutter. Carbon fiber reeds have a high spring tension. Fiberglass reeds have little spring tension and will flutter at higher rpm making the power flatten out.
