I'll check that out when I get home. I may also pull the airbox lid and see if that helps

I need to check the needle setting. I just pulled the carb apart and cleaned everything. Like a dumb as*, I didn't write any of the settings or jet sizes down before I reassembled it. I'll check the plug again too. I just went and replaced it when I bought the quad

Just out of curiosity, what should the compression read? I just want to check it.

It's a 2001. What should the compression read? I have a tester just not a damn manual ! Anyone know where there is one online?

Thanks for the info on the airbox lid. This thing is in great shape. It just annoys the crap out of me that I can't get it in tune

My KFX seems to do fine at this altitude, just minor tweeking

Hello, my name is Jim and I'm an........... Sorry, wrong forum:twitsy:

Just wanted to say hey to everyone.

I ride an 04 KFX400

Thanks for the help. I'll take the carb off and check the jet sizes. It seems to be leaning out and falling flat on the top end.

What part of Mass are you from? I grew up in Haverhill

Sorry I wasn't clear. I was talking about the mixture screw. I was wondering what teh factory setting is

OK, I bought a blaster for my wife. It's in great shape but it falls flat early on top end. It seems the worst in 1st and 2nd gear. As you get up through the gears it seems to be a bit better. I have pulled the carb and cleaned it. It didn't help at all.

Can anyone tell me what the stock jet sizes are? Also, what should the mixture settings be for a bone stock Blaster? I am at 5000 feet in New Mexico

If anyone knows another reason, please speak up.
