2002 400EX carb Help

So i finally got around to pulling the carb on my EX yesterday and oofta I don’t know when the last time the previous owner cleaned it was, or if he ever cleaned it at all. I mean hey it wasn’t horribly bad, but there was plenty dirt and gunk caked in there. I completely cleaned the outside of the carb thoroughly before I began disassembling to avoid furthur contamination on the inside (As anyone with a brain should do). So I have a few questions that i need you guys to help me out with before i put my parts order in. 1. is there a way i can check the condition of the Air Cutoff Valve without a hand vacuum pump tool like it recommends in the manual? I’m sure the valve is fine but i have to order new o-rings for it anyway so while it’s apart i figure I should try to test it out now rather than put it back in in non-working order. The Accelerator Pump is another think i disassembled and cleaned out thoroughly. These components are really the only things i’m worrying about a whole lot cuz i don’t know much about them(my previous machines didn’t have them) so please leave me your opinion cuz i’m already dumping $100 into this carb!! Shit adds up fast and man do they charge an arm and a leg for this shit!! Yes you read right $100!! all that just for the basics: Gasket set, O-rings, New Vacuum hoses and a fittings becuase the old hoses were cracked and the fittings busted on me when i was pulling the carb :icon_ cry: , also i’m ordering a new Pilot screw set just to play it safe and a new Main and Pilot Jet. all these are OEM and genuine KEihin parts so once it’s done i can sleep in peace at night knowing there’s good shit in there. So my second question is: what sizes of jets do you experts think sound good for this set up: All stock ’02 400EX except a current K&N air filter which will be thrown sooner than later hopefully for a UNI (better protection) so with that said my quad will be all stock except for a UNI air filter. I am getting a 42 Pilot because i’ve heard a lot of guys put them in even stock because it helps with cold starts anyway. and for the main i’m thinking a 152 or 155. stock is 38 Pilot and 148 Main so let me know what you guys think. BTW the stock jets were in the carb when i disassembled it and my elevation is 1175 feet roughly any reccommendations are welcome guys please help me out here.

00 Trx 90 No spark?

I have a 2000 Trx 90. Not getting any spark. No power to the coil. There is a yellow wire running off the stater and it seems that its the only wire that has power. I believe there is something wrong with the neutral safety switch. I was told that the yellow wire could be for a headlight. I tried grounding out both connections coming off the neutral safety switch. Still no spark. If there is power coming off the yellow wire when i pull it i know the stater is bad. What to do now?

Brake lights do not work

Hi.

Does anyone know what could be the problem in rear brake lights not working on 2014 RZR 570. Rear red lights are working fine, but when you press the brake pedal they do not shine brighter as they should. An electrician checked all the wiring and everything looks well.

Any ideas?

Thanks for the help!
