My machine sticks in reverse until it is completely warmed up and then it shifts perfectly once it is completely warm. I have to literally yank up on the shifter to get it out of reverse. It will shift up and down fine in the forward gears just not reverse. It's a 2005 Honda Foreman TRX500FM5. I'm hoping someone can point me in the right direction. I tried searching it but didn't come up with anything.
Thanks in advance.
I have a 1999 Yamaha Big Bear 350 4x4 trying to get fixed up so my grandson can go out in the woods with me.
We have owned it over 10 years. It got harder to start, until it finally would not. Replaced the carb. Right afterwards, it started and ran nicely, but after turning it off, would not restart. Tonight I used starting fluid and ran, then died. Adjusted the idle up a little, used more starting fluid and ran great. It idled about 15 minutes. Turned it off, and restarted. Ran it around the yard about 5 minutes. Turned it off, and would not restart.
Any ideas or suggestions would be greatly appreciated!
I have a 1994 Kawi Bayou 400 which had been running well until it sat for about a month. I left the carb dry while it was park and the temp had dropped below 0C in this time. Pulled it out last night to go for a ride and it fired up just like it should but noticed when I started to head down the road I could hold it to the bar and it didn't seem to accelerate. Lower gears weren't as noticeable but 4th and 5th it just seemed to have no acceleration and half or full throttle made no difference. if I tried to go into 5th gear with any throttle it would stall. I turned around and just poked home very slow and it seemed to stay running but this was between 15 and 20 km/h max.
I have taken the carb apart and it appears to be clean and nothing stood out on inspection to have dirt or ice. Is there something I should dig more into?
I have checked the plug and it appears to be sooty with easily rubbed off carbon. I plan to get a new plug today and test.
compression with the throttle wide open is 175 psi.
I have opened the drain plug in the exhaust thinking there could be a mouse in the exhaust or something but no difference.
I do find the engine is tickity compared to my 2000 Honda but I am not sure if this is just me looking for issues or if it has always been this way.
If anyone has any insight I would appreciate it.
In the last 6 months I have done new oil and filter ( mystik synthetic)
new Peak RPM CDI
I have noticed the fan comes on more often with the new CDI, could this be a program thing?
So this’ll be long I’ll give all the background first to see my issue skip to the ***
Hey I picked up a pit bike and a foreman for 800 the pit bike was running but the foreman was locked up. Sold the pit bike but when I took the top end off the piston I only found half a piston left. So knowing the rest of the piston was down in the crankcase I knew it had to be pulled and gone thru completely.
to pull the motor I went ahead and pulled the rear end off and unbolted the front diff to pull the drive shafts and pull the motor. Now I have the motor torn down completely and have all the parts of the piston removed. I know the rod and crankshaft is shot (heat discoloration and too much up and down play rod to crankshaft).
***so I’m wondering while I have the motor apart what should I check for? I know this motor died from heat as the oil in the head smelled like popcorn. So what should I check to make sure I fix the issue (overheating I assume) and not just the symptoms (blown up motor lol).
so put simply I don’t want to just rebuild the motor to have it overheat and repeat the process after 5mins of running
Here’s some pics
Hey guys, Im new here but I recently Picked up a '99 Foreman 400 that apparently just had a top end rebuild. It blows white smoke like crazy and ticks/knocks and seems to follow the rpm's. I haven't done to much trouble shooting yet, It starts and runs like a champ and has good compression. I was just wondering if anyone has any suggestions as to where to go.
Oh ya the top end rebuild the guy did was according to him he honed the cylinder and replaced the piston and rings, my fear is an ovaled cylinder?
