I have a 2009 Honda Rancher TRX420FA with shifting problems.
Usually it shifts ok when cold but after couple minutes it will stop shifting with no codes.
The 1st shift clutch oil pressure when in first gear is 74psi. The 2nd shift clutch oil pressure when in second gear is 74psi.
The 1st shift clutch oil pressure when in neutral is zero. The problem is when the tranny is in neutral the 2nd shift clutch pressure starts around 10-15psi and builds to 20psi. Is this normal?

I wanted to share a successful workaround for a "no-spark" issue on a 2009 LT-A400.
This is specifically for cases where the CDI has been diagnosed as faulty, but the age or condition of the machine makes the cost of a brand-new OEM unit hard to justify.
Note: This modification compromises the factory “no-start” circuits.
On some malfunctioning CDI units the internally damaged circuitry is only partial.
Feeding full time power to the Parking Brake pin, the unit is triggered to bypass the internal fault and produce a healthy consistent output to the Ignition coil.
The Modification
See the second diagram attached below for the wiring specifics.
The Result:
The machine has clocked over 1,000km since this repair and is still running strong with no ignition dropouts.
⚠️ IMPORTANT SAFETY WARNING ⚠️
Please be aware that this modification compromises the factory safety "no-start" circuits.
The machine will now start in gear. The safety interlock involving the handbrake is no longer functional. The machine can move unexpectedly if the starter is pressed while in gear. Proceed at your own risk. If you sell the machine or let others ride it, ensure they are fully aware that these factory safety buffers have been removed.

I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto-4 350 4X4 to use for hunting. I say 1987, but not positive. The owner is not positive about the model year, but he said 1987 sounds about right. He also gave me his son's Clymer manual that covers 1987-1999. The frame has rusted just enough that the full serial number is no longer readable. I can read some numbers/letters, but it is spotty. Anyone know how to determine model and year if you cannot read the serial number? I have included photos.
So it started fine when I got it home, but it would only stay running if the choke was open even when warmed up. No identification numbers are stamped on my Mikuni carb to determine specific model. The choke is controlled by cable connection on dash, so it is not a model that has the choke lever right on side of carb. Since it would only start and run with choke open, I decided to rebuild the carb using the OEM rebuild kit. Took it apart, cleaned jets, orifices, replaced o-rings, gaskets, etc. After reinstalling the carb, the engine will still only run with choke open, but now the engine sounds like it wants to shut off and there is a consistent low volume backfire from the muffler. If I rev the engine, it sounds better, but still continues backfiring.
The fuel screw was seated at 2.5 full turns before I cleaned it so I put it back at that setting.
I’ve looked high and low trying to find a video of someone rebuilding my specific carb, but it appears there are many variations. Appreciate any guidance to get it back to running like it should. I have included photos.
Any guidance on figuring out model year would be greatly appreciated.
Thanks for your time.
