Hello everyone !
I'm currently rebuilding my carburetor on my Yamaha moto 4 350 1987, first time I rebuild a carb 😅 ! It was leaking fuel from the overflow and inside the intake ....
When I took off needle (the platic top part was stuck like crazy) I had a spring and inside the kit there is a spring, an O-Ring and a washer.
Left is the needle that was in the carburetor and right is the new set (I already tried to mount it but it didn't felt right and I accidentally broke the o-ring)
Anyway, I saw in some videos and diagram that there is no spring in here. So should I put the spring back ? And where ? On top of the needle or bottom ?
This is an original Mikuni carb :
Thank you ! Also if you have any additionnal tips please feel free to share I want to learn the proper way !
I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?
Hello, i recently bought a 2000 Suzuki LTF500 semi-automatic. I was riding it and found out that its hard to shift into 3rd gear and above. could it be because of the tuning because the rpm might be to high, cuz in neutral it would sometimes rev high by itself? or could it be something in the trany?
Also it shifts easily when off
I went out to ride my quad today. When I started it up it ran for a minute, then died. Since then it will turn over but won't start. I've check the spark plug and get great fire. I have had this quad for about 6 months, and very new to breaking it down. But need help. Thanks

This quad formerly ran fine but started to run poorly as it wouldn't idle or rev easily. The current problem is as specified below.
Starts and idles fine when cold. Will rev to mid range when cold. As it warms up it will not rev and idles poorly as it gets warmer. I thought might be a problem with the ignition coil so I replaced it with a new one, no improvement. It doesn't backfire or stutter. It just falls on its face when the throttle opened. Also no smoke out exhaust.
I changed the carb to a new Mikuni VM32 which is a common swap. Fuel tank was cleaned, a new shutoff valve, new fuel filter, new fuel line installed. Air filter, ignition coil are new. CDI was recently replaced with an aftermarket unit.
I verified fuel is flowing from tank to carb. Fuel tank vent is not clogged.
Still no improvement.
Possible valve adjustment problem?
Any advice would be appreciated.
Hello folks, I have a yamaha timberwolf 250 motor I'm putting into a tri moto 200 frame and need some help with the wiring for it. The wiring harness I got with the motor has been damaged and missing a small section so my issue is that I have 3 white wires coming from the stator assembly which connect into another 3 white wires on the voltage regulator. My question is does it matter which of those white wires go connected together or are each of the white wires different and need to be connected to the appropriate wire on the voltage regulator. Any advice or help is appreciated. Thanks.

I was wondering if anybody seen that problem and know what could cause it
it’s new to me 2018 Yamaha grizzly 700 with just over 4000km
it starts fine and runs great until it gets to normal running temp. Fan turns on few times and than it stalls. If I try to start it right after It won’t start but if I let it cool for a while it will start and run normal for a bit and than stall again.
so far I checked the stator output voltage and it’s around 22 volts AC between all 3 poles. I measured voltage on the battery while it runs and it’s around 14v so charging seems ok.
I’ve read somewhere that it could be the coil but I’m not sure how to test it
does anybody have any ideas what could that be ?
ok help so according the service manual, Idle Air Mix Screw (aka Pilot screw) should be initially set to 2.5 turns out from fully seated.
If I do that the motor doesn't want to start or stay running...right now the pilot screw is probably somewhere near 5 turns out....I'll take the carb off tomorrow to count to know for sure.
mind you the carb got a new float seat,float needle and various other components in the kit.
To get the motor running I hard to turn the pilot screw out quite a bit, and turned the idle speed screw in quite a bit...I didn't hook up an inductive tach to know what it is idling at, but does sound about right.
What should the idle speed adjustment screw initially be set at (the one that has the black cable sheath with a knob you can twist easily)?
Is there a special tool to turn the idle/pilot mix screw whilst the carb is on the running motor? I am using a slotted screw driver bit (normally goes into a driver) by hand..makes it hard to turn the driver and hard to tell how many turns .
