Leak Jets

First off: 2005 CRF250, 800ft at around 70ish degrees.

Just wondering what you guys are running for leak jets, and what mods your doing.

Had my bike on the dyno yesterday. After we got the jetting sorted out it was putting up 33.89 hp, with 18.8 foot pounds of torque. Horse power seemed a bit low? I've heard Honda claimed stock it had 34, but couldn't really find an actual claim from anyone who really knows anything.

Bike has pro circuit T-4 complete system, Wiseco 13.5:1 piston (about 10ish hours ago), and has engine ice for coolant, cus it was all I had laying around. Everything else enginewise is stock.

Anyways the bike had a real bog right from acceleration. Too lean. Has a size 55 leak jet. Smaller the leak jet, the more gas. We didn't have any other size leak jets, but we did have another 55er. Sottered one of them shut, then drilled out the hole smaller. This helped a little bit, but nothing to where it should be. Just for kicks we then drilled the hole bigger, made it worse. Next we put the other 55 in, and tried the O-ring mod on the AP, helped a little bit as well, but not close to perfect.

Well we ordered some more leak jets of differing sizes, and a different stiffer spring for the AP which is supposed to eliminate the need for the O-ring mod. If this doesn't work, I am probly looking at a Boysen quick shot cover, or adjustable leak jet. Which one?

I'm wondering if others are having this problem, and how they solved it?

Also getting the head ported and polished next week, and if this doesn't get me over 35 I'll probly do the ever popular 08 cam swap.

Thats what doesn't make sense to me. The guy that was helping me with it knows more about it then me, Im a noob when it comes to jetting.

Yeah, I have seen the stream that pumps out of there, seems like alot of gas to be running too lean. But the sensor showed that on throttle wack it started lean (same time engine cut out), then after about 2 seconds the mixture was right where it should be all the way through the range. Mixture was good at idle as well.

Unless There was too much gas to be burned, and the sensor was not picking this up?

I don't know....

Not exactly sure what kind of sensor it is..

But when I put the piston in it, I had the subframe off and airbox off, and the squirt was not hitting the slide at all. Could be too late though? But when the different size leak jets come in, we will figure it out.

Rode it today and yesterday, and it was already a big improvement from before.

This guy has been through all the training etc, and does dyno tuning/mechanic work for a living. I'm 17 years old, and learned everything I know from hands on experience, Clymer shop manuels, and the internet.

I want the squirt to be as soon as possible, without hitting the slide. Correct?
