@Frank Angerano there are a couple things to check before modifying the wiring from the research i did overcharging/ undercharging can cause issues that are similar and also the cdi can go bad and cause a similar issue, also check the valve adjustment. i will try to get better pictures of what i did but the neutral switch should be grounding the wire going to the cdi to tell it it is in neutral this also allows the starter to be activated. In my case the wiring on my quad is already hacked up so i had no problems cutting the wire and if it didn't work splicing it back together.

@Frank Angerano i believe it is either blue and black or blue and red video-1587145503.mp4

Update: The issue is a wiring issue with the signal wire for the reverse limiter getting power from somewhere other than the neutral switch. My temporary fix is to cut the wire and it is running great.

Check the o-ring or gasket on the intake where it connects to the carb and the engine i have seen a case where the o=-ring on the engine side went bad and the machine just shut off and didn't start again.

@MarkinAR i have been in the carb but wasn't able to clean it as good as i wanted to due to the previous owner stripping pretty much everything in it.

I have a 2001 suzuki quadmaster 500 4x4 that has a rev limiter when it is in any gear other than neutral, i have already fixed a bunch of stuff on it and would love to just bypass it if anyone knows how. Thanks for any help. video-1583184277.mp4

Maxxis Bighorns are an all around good tire i have them on a 2007 can am outlander 650 maxx xt and they work great in most of the terrains we use the quad in mud, loose dirt, loose gravel, packed trails, in snowbanks.

I have a 2001 suzuki quadmaster 500 4x4 automatic and i was wondering witch atvs it shares parts with i know it shares some with artic cat. Any info would be helpful.

@Frank Angerano Thanks for the information

i have a 1986 yamaha moto 4 200 and was wondering if i could put a 350 or 300 jug and piston on it to bump up the cc?

@GrizzlyRider it tries to move when it is on the ground but won't when i jack it up so the rear tires are off the ground the tires spin and it runs great

@GrizzlyRider the carb is set up within spec, the fuel shut off/pump is working great. it has a cvt clutch with a foreward reverse transmission and chain drive from that to the axle. it was having trouble shifting from neutral or reverse to drive so i opened the trans manually put it in drive and took the shift fork out, but i can easily spin the transmission by hand.

I have a go kart with a 150cc gy6 engine it will run great and rev when i have the rear tires off the ground but as soon as i try to drive it it boggs down and doesn't move i cleaned the carb and fixed a small vacum leak and it still does it., Any ideas on what it could be?

look at the cvt belt we had a belt start to break apart and it started to get jerky.

it is probably a case of bad connections in the jumper cables if you jumped the 2 posts on the solenoid it should have turned over unless the starter is bad but by what you said it is a bad connection to the battery i would still check the main fuse though as that could cause the key not to work.
