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
Grandson got a couple China made ATVs, lucky me, been a while since my motorcycle days, but I’ve mechanic and body worked all my life. Got an issue with the 110 cc one that’s got me scratching my bald head. Replaced carb, adjusted and checked all I see that can be done and it still Boggs out in forward gear , but will spin the tires in reverse and not bogg at all. What am I missing hear ? Anybody got any ideas on what to try next? Please let me know, I’m sure that the best thing to do would be to get rid of the the things and buy a real Atv, unfortunately the grandkids can’t afford it and Grandpa is supposed to be able to fix anything don’t acknowledge. Help needed!
Do the small 50cc's have a way to set the speed. Im wanting to get one for my kid and i need to set it to go slow. I know the chinese knock off fourwheelers do but i dont really want one of those
Bet you've never seen a Tonneau cover that can hold 2 - 4-wheelers on top of it. This is a home-made heavy duty fiberglass truck bed cover that was used on an 2000 F-350 with an 8' bed. We have used it hundreds of times but are getting out of the 4-wheeling fun. You can waterproof with a rubber seal, not included. This leaves the area under the cover open for all your gear and firewood. It is white and in great shape. 4-wheelers NOT included.
