Hello! I have a 2003 honda trx650fa that shifts through all gears manually and all gears in 4wd but when in 2wd it wont shift to 2nd and 3rd. I have changed out the wiring harness, both the engine and transmission control units! Any idea what is going on? All is normal on the dash speedometer...

Have a new 2020 Honda Fourtrax Rincon, 620 miles, been in the shop 3 times, the PDM just stops, resulting in it loss of 4 x 4, the engine shuts off when put in reverse, speedo races up and down even when standing still. Any suggestions? Honda does not seem interested in helping/fixing even...

Hey guys I got a question for yal, about 5 months ago I noticed I lost a lot of power with high revs so I decided to to a top end rebuild and I honed the cylinder and got a new tuner but yet it still does not want to rev out like it should
