the adjustment nut is on the front cover, 14mm.

and that my friend, is how it gets you every time !..folks want to save a few bucks, when in the long run, it always..ALWAYS ENDS UP COSTING THEM MORE MONEY AND TIME !.

it truly boggles my one brain cell, trying to figure out why atv owners who ride an utility atv, want to '' get that one extra hp '' ?!..lol. you can only get so much from these machines, after that..its all over but the crying. soo..bottom line: don't bother trying to get 100 hp from an engine that is designed to give you 10 hp..lol.

oem all the way, stay far...far away from any after market parts, when you can get oem. if and when it comes time where we can't get oem anymore ?, then i will use china junk ( we won't have a choice ), until then, i will use oem all the way !. just ask jeep69 what he went through awhile back when he tried using a after market head gasket ?!!..lol.

i always use the correct top end parts. is there a reason you are not using the correct top end parts for the correct engine ?. can't answer your lean question ?, as i don't gamble on something i know nothing about..lol.

if and when you get the rear case back off to get to the neutral switch. MAKE SURE YOU INSTALLED THE SWITCH CORRECTLY !. by this, i mean the switch must be installed back into the shift drum the right way ?, or..you will have it out of alignment. get the cover back off, take a look at the switch, the shaft has a roll pin stuck through it, this roll pin has to have the longer end directly over the rasied letter N that is stamped on the top of the switch. brown plastic part where the wires are at. look for the letter N stamped into the topside of it, now rotate the longer end of the roll pin where its right over/facing the letter N. now install it back on the engine, MAKING SURE THE ROLL PIN GUIDES INTO THE SLOT IN THE END OF THE SHIFT DRUM.

there should be a sticker somewhere on the frame under the front fender, it will read something like trx420fm-with maybe some letters after the fm. the round connector in your first pic is normally wired into the main harness, if this is the case ?, you will have to buy a whole wire harness to solvet this issue.

thanks, but we need the FULL make/model, 2wd ?, 4wd ?. i see its a '22, and its a trx420 manual shift, but this does not narrow it down to the exact model, there is a ton of these listed to look up.

under handle bars in the front, black plastic part, should have a lid on it ?, open it, under it is the main fuses.on some of these models, there is a tall rubber boot near the battery it has a red wire going in, red wire going out, open the cap, easyly pull the holder out of the boot, inside this boot is what looks like a tiny wrench ?, this is a fuse ( don't ask me why honda made these like this !..lol ). not all trx250's have this fuse, but some do.

these models do not have a pull cord, ele and kick start only.

welcome dastevoe.

it could be the angle sensor ?, it also can be a bad shift motor ?, i've seen these problems alot. i have even seen the shift motor magnets come apart inside the shift motor. last but not least..you may have a loose bolt on the end of the shift drum ?. only way to get to this is remove the front cover.

most elec shift machines have the c.d.i. part built into the pcm, all the older manual shift machines have a fan control and c.d.i. seperate unlike the ele shift's do.

can you tell us the make/model of your atv plz.

over 300 from rmatv..i checked..lol.
