330r seems like it runs out of fuel

[250rracer90]

i have a psi 330r PV kit on my bike went riding today and low end is good could prolly ride all day on low and mid range 1-3rd gear WOT it goes great shift into 4th and it acts like it runs out of fuel give it gas and try to save it from staling and nothing but kick it enough to get fuel back in the cylinder it starts right up and runs fine i just went threw cleaned the carb everything looked ok but i cleaned it out anyway checked my reeds they looked ok checked the spark plug its a little dark but its not fouled took the powervalve out to make sure it was opening and closing freely and it was checked fuel flow from the petcock and it pours out of there so im getting plenty of fuel from the tank. after putting all that back together i havent rode it yet it got dark and i called it a night im hoping something i did took care of the problem otherwise i got an ignition problem that developed and i hate messing with electrical lol. any other ideas that might lead me to my problem would b appreciated, thanks

You may have other issues. If you are running in any gear in WOT, then you are on your high speed jet in the carb. Your low speed jet is just that, for running not at wide open throttle. So if your running ok in 1st - 3rd gear at WOT, then you should be well in your higher gears at wide open throttle. I really don't think your problem is fuel. Sorry to be the bearer of bad news.

its got plenty of compression i no for a fact it has nothing to do with the motor itself im just running out of ideas. could a plug cap shorting out do something like that? or a coil or stator going bad? it just seems weird all of a sudden it wants to run like crap this quad has never let me down its gotta b something simple

It could be as simple as an old plug. Electrical gremlins can be ugly. I don't know how fresh your fuel is, but that generally causes problems across the entire rpm range. I would say check your air filter for cleanliness as well, but that wouldn't really cause you problems in the high end only and your spark plug would be a little sooty if it did. Make sure your ground is clean, it's one of those simple no cost things to check. Check your electrical connections. Try bypassing the kill switch and see if that makes a difference if you want, another no cost thing to rule out. Any loose wire could be jigging around for a bad connection at high speed due to vibrations and such. Check your wiring for worn insulation and a possible grounding problem or even a pinched wire. Try to check for the things that don't cost and once you exhaust those, no matter how silly, then you have to start looking into the possibility or replacing parts. If you have a shop manual, they usually give you specs to check out your wires for resistance and stuff like that to help with testing and identifying problem areas. Chasing electrical problems sucks. LOL

i could throw a new plug in it who nos the way my luck goes lately the electrode is going bad, fuel is fresh and mixed properly 32:1, air filter is clean, ill check grounds there isnt a whole lot of wiring its set up to race so that kinda makes it easy,theres just a teather on it no way to bypass anything i have a shop manual for it i no the specs anyway tracing electrical on these R's is nothing new to me seems like everytime i do it i hate it more and more lol ill keep u updated though thanks for all the help

Well, with heat cycles and vibrations and time, it can take it's toll on electrical parts. Heck, even new parts can be hosed up brand new out of the box. I'm not sure if your coil is one piece from the coil out or if you have seperate coil wire and spark plug cap, but those are relatively cheap and maybe a good idea to keep a known good coil for testing. If your machine has it's original stator and ignition coil, you may want to check those. And sometimes a stripped down wire harness can be a bad thing. LOL Your dead mans switch still has to have a place where it's wired into the ignition system. If it's hard wired in, you may want to put electrical connectors on it to make it easier to replace in the future. A dead mans switch can still go bad from vibration and dirt and stuff.

yeah i no what u mean ive seen my fair share of stuff go to hell in a hurry the coil and wire itself looked to b once piece i didnt look at it real good but i dont no how old the stator or coil is so if what i did tonight dont fix it then i no where im gonna start next that teather is wired in weird whoever did it didnt no what they were doing but somehow it still works lol im finding more and more stuff everyday on it that kinda makes me wonder what i got myself into its just little stuff though but it ends up turning into something like this i guess i really cant complain though the price was right :D

[250rracer90]

well i went threw checked all my wiring checked the teather theres nothing wrong with it all the wiring looks good plug cap is tight so i figured id dig a little deeper in the motor i pulled the flywheel cover off and oil dumped out of it like it was full all the way to the top of the cover it didnt take me long after that to notice that the counter balancer bearing holder was cracked on 2 of the ears that hold it into place and it was loose so for some reason and to my luck the only thing that was holding it in was the oring otherwise the way i run it it woulda blew apart in a hurry so the balancer holder let all the oil in cause it wasnt secure. i soon after noticed that the pickup coil was loose and i moved it just a little bit an the mount broke so that was in there bouncing around off the flywheel to can see the marks on the flywheel where it was hitting mayb thats got something to do with my problem? guess im ordering parts and going to find out 131445131446

For the counter-balancer bearing retainer, get a new billet aluminum one from ESR. They're much stronger than the cast aluminum ones that came from Honda.

good to no cause thats what i ordered
