400EX ‘struggling’ in wheelie

Hello one and all. I noticed something strange my machine is doing, only in a slow(ish) wheelie. It seems like it is running out of fuel at an @11:00 angle? I can clutch it up into a wheelie no problem, but after about 10 feet, any throttle input just sounds like "buh-buh-buh-buh", and has none of the smooth acceleration/power I get when level . It’s weird that it only does it at those angles??? Runs good on level surface.

Currently running a 42 pilot, 165 main, Outerwear lid cover, K&N filter, stock exhaust. Pilot screw doesn’t seem to make much difference with regards to position, right now it’s at 1 5/8 turns out.

Any tips and advice is greatly appreciated!

OEM parts

is there a difference in dealer oem parts than an online oem part? the carb rebuild kit i got from the dealer was over 1/3 cheaper that partzilla, because it had more in it.(except for that stupid rubber plug). the dealer sells the tie rod ends as a kit that is complete with everything from end to end only. And i was told that dealer parts(by the dealer) are better because of quality and last longer. Japan might even use china parts for all i know for sure. Made in USA doesnt carry much weight…..

Grinding from front right

I have a very noticeable grinding noise that comes from my front right side. Seemed most likely to be a CV joint as I couldn’t think of what else it could be. The thing is that I couldn’t necessarily change it by turning, driving different speeds, or anything else. In fact the noise comes and goes to a degree.

I jack it up and turn the wheel – the grinding noise isn’t real loud but still present. So, I take it apart and it certainly feels like the inner joint is binding a little but there is no physical damage I can see. The boot isn’t damaged and the grease was packed well. Does that mean it may not be the joint? What else would make this noise?

Oh, somehow I lost a ball bearing putting it back together, too. Does anyone know what size and/or where to get one?

Thanks.

honda atv service schematics/service manuals

maybe this should be at top of technical discussions. a lot of people dont seem to see it. i didn’t pay attention to it for months. as soon as i seen Repair and Maintenance, i jumped in without looking any further. i had previously downloaded service manual, and have cleymers, but i was so interested in my problem, i only didn’t focus on any other subjects, and there are quite a few. it is one of the most important subjects for the uninformed.
