I took my 1991 kdx out today after putting boyesen reeds in it. I didnt note much bottom end or power increase at all, could this be because of bad jetting or dirty kips, or do they not do make much difference at all am I supposed to be able snap the front wheel in third gear as opposed to second or not? Anyone know

Some people say the difference is like night and day between stock and boyesen but I dont really know about that.

I wouldn't say that it improved things to the point of "wheelies in third gear" (where did you hear that BTW?) but it was definately a noticeable change in throttle response. More of a power-delivered-more-quickly effect.

But you're on the right path with jetting - learn everything you can and just do it!!

What do you currently have for gearing and jetting motofox? Temp and altitude?

Definately had a substantial gain on my bike

With great pull off the bottom

Then when I fitted the VF2 on it was like night and day again!

I can easily pull a gear higher, find myself in 3rd or 4th when I thought I was in 2nd or 3rd

My gearing is 13/50 my bike runs an fmf pipe, boyesen reeds, modified airbox lid, and the jetting is a 1172n needle, 45 pilot, 158 main, my altitude is mostly sea level up to 44 metres, and the temp is 59 degree fahrenheit to 79 degrees.

I do find mid to top pulls fairly well in my bike, but no better than before, I really was hoping these reeds would give me more botom end grunt.

too rich. Jet for the reeds.

How's your topend?

If the reeds did not do much, something's amiss somewhere

Is this on a 200? I did not find your bike in here : http://www.kdxrider.net/forums/viewforu ... =0&start=0

If it is a 200 your jetting is a little odd, you are up 3 sizes over stock on the main and down one size on the pilot

That main is a little fat....

Post by **Mr. Wibbens** » 01:59 pm Mar 04 2007

just a little

Error on the side of caution!

Thats funny I know my main is a bit high but I ride sandy conditions and my top has got plenty of grunt no better than before but it has plenty isnt the pilot the on which may affect throttle response I do find I have to change down alot to get up hills
My air screw is 1 turn out at highest idle isnt that correct.
it is a 200
