no top end
no top end
I am running a pwk and it seems very flat on the top end, almost like a lack of fuel problem, but its not. I have no clue how to tune this carb, where should I start?

very true, 500s are much faster if you take advantage of short shifting and using the torque to run a higher gear. unlike my 250 that you ring out to make good power.
my 85 has massive midrange hit, but if you let it rev out to max rpm it feels very weak. just how large bore single cylinder engines work... unless you port them for the moon

thinking of jumping over to the AF side of things

I have a kx 500 running the same way. But it also surges (let off the throttle and Ping, Ping, Ping, ping..........) then when I get back on the throttle it has to clean out a little before it runs smooth again. I feel like it gets up in the RPM's but does not make any power up ther just noise? This bike has ran this way since i got it. I have gone up and down with the main jet and in and out with the air screw but never fooled with the pilot. 160 main seems to be the best so far
Starts right up cold with choke on no throttle. Needs the choke to run when cold first 2 mins. Starts up easy when hot. no throttle. even idles

if it really lean it will rev out good, but be way down on torque, top end torque, as in it wont be able to hold 4th gear up a hillI feel like it gets up in the RPM's but does not make any power up there just noise?
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.
4stroke=dead fish

This does make some sense. I did really notice it after riding my 00 250. That bike is by far the best running 250 I have ever ridden. So maybe swapping between the two made it more noticably.DieHard2Smoke wrote:very true, 500s are much faster if you take advantage of short shifting and using the torque to run a higher gear. unlike my 250 that you ring out to make good power.
