350x the way I like it, with a wide ass

[The Goat]

jason...bad news, i live in the middle of *Edited**Edited**Edited**Edited**Edited**Edited**E dited* nowhere... i couldn't get cell service if my life depended on it. and that's my only phone. how about I bring you the bike in the back of my car, and you tune it. lol

[Jason Hall]

Man I wish I could meet ya half way LOL. Well just keep on trying & don't get bummed. It's just a carb, even though I know you would love to HAMMER IT flat with a big sledge. I would suggest you watch the exhaust after every change. If you get a chug of black smoke when you first throttle Into It, that means to much fuel. If It hesitates or pops back through the carb that Is lean. Is there any chance It Is sucking air (vacume leak).

[The Goat]

well to be honest...putting it on was a helluva lot harder than jetting it will be.

there is zero chance of an intake leak now...i changed out the oring...and used a high temp fuel resistant sealer.

it's rich...it has to be. it feels like it's burning through the extra fuel when it's reving up...slowly but surely. no detonation or anything, just a slow slow rev.

[SWIGIN]

whats the plug look like?

[The Goat]

plug was misleaded...sold the carb.

now the guy i sold it to is saying that something butterfly is not allowing the carb o run correctly. worse, I checked it before I shipped it and everything seemed fine to me. A problem would explain why it wasn't working right for me.

idk...got a new carb in the back of the scion...soon as I get a day off from work, I'll fool with it.

can anyone throw out an approximate jetting with a 37mm fcr?

[The Goat]

can anyone explain what all the jets in the 37mm fcr do.

I mean obviously there is a main jet, and a pilot....but there is also a 68 jet in there...that seems to the mikuni style. then there is also some other sort of jet in the intake of the carb coming from the airbox.

the problem is...since I don't know what they do...I don't know how to adjust them.

also...there is an issue of the cable for the carb not fitting the throttle. now I'm either going to buy a throttle for the crf250r or a motion pro twisty...which would work better and last longer? also, how exactly do they install?

[SWIGIN]

ok, first off the tube going to the intake side of the carb should be the hot start...its not a jet.

think of it as the opposit of a choke....when hot and if its hard to start you hit the hot start like a choke knob and it sends fresh air to the cly.

the 68 jet sounds to me like a pilot....thats the only thing i can think of that would be about that size.

if you didnt get the quad carb you would need to modify the cable to work with a thumb or swap to the quad carb linkage/cable brackets....or go to the dark side and get a twist.

[The Goat]

thanks for solving the mystery of the hotstart...but well the thing is the pilot jet is the 42....i know that...it looks just like a normal pilot jet.

but there is another jet in there, that looks just like a mikuni main jet...it's a 68.

to be honest, I want to get a twisty...I'm just unsure if I should buy the throttle from the bike the carb came off of, or buy a motion pro.

I'm also unsure as to how they install. do you cut your bars...or what?

[SWIGIN]

no man, a twist throtle just slides on your bars...simple

[The Goat]

well, bought a brand new 450 twisty and slapped it on there...had issues with the shortness of the carb, got a little bored this evening, stuck a peace of rad hose with a filter on the end and started the beast up.

42 pilot, needle in the middle, 168 main. she's lean in the middle, rich on the top.

but even still....she runs like a raped ape.

Idk what you other guys are running for gearing...but at 14/42 on 20s it lifts the front going into 1-4, you honestly can't stay on it without leaning very far forward.

I'll prolly be going to 14/35.

everything seems to be all set, and I know I'm getting oil to the top end, as I have quite the leak coming from a rocker cover.

but yes indeed she takes off.

all I need now is a lightened flywheel, some helicoils, a longer swinger, a ten inch front rim, new front tire, skid plates, and a ton of powder.

also, this twisty is going to take a lot of getting used to. Idk if t is because I'm using a 450r twisty and a 250r carb, but it doesn't release the carb as quickly as I would like.

kicking it over is easy...roll it to top dead center, stand on the kicker, and jump.

[The Goat]

bump bump...

to get the flywheel off of the 350x...is it the same puller that is used for the 200x or atc70? If I remember right the puller for the 70 was larger...

[Dirtcrasher]

It's the one thats just a simple bolt, not the one that threads into the flywheel and then a smaller bolt drives it out. Thats the 250R type and even the ATC70 has that type....

Sometimes the front axle or rear axle hub threads are the same size and pitch and can be used in a pinch. I find Toyota suspension bolts work great as cheap pullers, or pushers you might say

[The Goat]

so it's the same as the original 200x?

[SWIGIN]

no....200x's were 14mm

350x is something like 19mm, same idea but its larger

[The Goat]

damnit, now I have to order that too...everytime I try to use the front axle, I have issues with it stripping the first few threads.
