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?

Headgasket leaking pushing compression into oil passage

The cheap top end kits that include a cylinder are mostly junk

Piston and rings will be installed on connecting rod first. Then cylinder (jug) is installed onto piston with rings compressed using only your hands, no tool needed.

Yes you can rebuild top end without pulling motor. Cylinder and new piston should be brought to a machine shop that can bore small cylinders. The vent line that goes into air box will have a small foam filter at the end.

Namura kits are cheap and work fine. You will want to rip apart the engine before you purchase parts. Measure the cylinder and check the head/valves for leaks

Most likely the oil ring. You should rebuild top end, bore cylinder and use bigger piston.

its the exhaust gasket

If the honda has a hydrostatic transmission I would recommend OEM honda GN4 oil, 10W-40 for most hondas 2003 and older and 10W-30 for most 2004 and newer. Hiflo oil filters are a good aftermarket option.

The second nipple that is capped off is another vent, same as the otherside. The carb only needs one vent to work properly. If the fuel pump is bypassed the machine will run out of fuel when the tank gets to approximately 1/3 full (just my guess) Fuel pump is used for when the fuel level in tank gets near level with the float bowl on carb. I would not recommend using an aftermarket cheap carb, they are crap. The fitting is probably for the pulse line on the fuel pump. Rebuild original carb is best

I only repair

I run a small atv repair shop and have a large collection of pdf service manuals. Let me know if you want me to send them your way

I use john deere hy-gard low viscosity to replace demand drive, its the same thing

If some crazy person wants access to all my files let me know how I can share them, I have about 45GB (size) or 93GB (size on file) of info. Looking for someone to organize them and add to them anyway they know how.

Thanks for everyone's input. I am trying to figure out a way to keep it organized and easy to find the right manual. Quadcrazy has manuals listed by make only. Subfolders should have model year or engine size at a minimum
