Project Clapped out 1998 KX250... what works?

<< < (8/8)

sandblaster:
Well... We have 15% right now. But looking at the dyno charts we need to lean the midrange a bit and the top end.
We are running it on a second dyno later this week to verify the first dyno numbers.
I'm betting we will get it to between 17-18%
But remember... this is very early in our testing.
We are going to be using different heads, pipes, and port mods to see what we can get out of it.

Also, sometime this month we are going to put Brute's old KX500 on the dyno and see what it pulls.
It is completely stock.
Then we will do the turbo crank mod to it and see how it reacts.
Remember, KX500's don't respond to crank mods as well as the smaller bikes do.

The cost of a Turbo crank is 350 plus shipping... Figure about another 50 there and back if you insure it through USPS.
So it is not a cheap mod but if your doing your crank anyway you might as well do it.... IF it pans out for the 500.
I'm hopeful but we won't know till we know...
