help with motor

Hi guys,

I need some advice.
I recently rebuild my 500 as it had piston slap it has 3000 miles. I used oversized Wiseco pistons (502cc)with ceramic skirts and re-bored the sleeves piston to bore clearances where set at .0038. 500 miles later the piston slap is back only on the front cylinder just like before. The bike was rebuilt by a reputable guy with lots of experience but I cannot work out why its come back so quickly. I know there a common problem with these engines and the way that front cylinder wears on the thrust side/intake side. The pistons have 4 oil control holes to lubricate the skirt of the piston whereas the stock ones had 2. The bike has not been tipped over or drowned or overheated, I really need some advice to a cure to this problem because it gets costly rebuilding every 500 miles lol.

Cheers

New project: air compressor with GX160 Honda engine

Had a buddy drop off a wheelbarrow style compressor yesterday. He farms and it was an old one he kept in the back of a farm truck. One of his farm hands flipped the truck a couple years ago, throwing the compressor out. Looks like I’m missing the pull start and the air cleaner assembly. It’s been stored in his shop, so hasnt been sitting out, but the sparkplus was out. It has a Honda GX160 motor on it. He said I could have it as he’s bought a new one.

I tried spinning the motor over by sticking a screwdriver in what’s left of the recoil starter and it won’t budge.

Any ideas where I should start on turning it over? Any kind of safety/ lock out feature that might have tripped that would keep it from pulling over?

It’s this company, but has a Honda GX160 motor.

2001 Sportsman 500 DUSE gear selector question

Hi everyone. I recently bought a 2001 Sportsman 500 Ducks Unlimited Special Edition from a guy and have been doing a lot of much-needed maintenance. The gear selector boot was pretty much non-existent so I took the thing apart, bought a new boot, new o-rings, new springs, and cleaned the box completely. I am reassembling it now but I cannot remember how the centering spring and centering dowel go—does the dowel slip into the hole first and then the spring on top of it, or does the spring go first and then the dowel, and then it’s all compressed when you bolt the boot on?

Thanks in advance for your replies.

Battery Died – Can’t seem to get it to hold a charge

I had my Quest 650 buried in the woods and hitched to my Log Arch holding a nice long Oak log when I got a call on my cell. In my haste, I left it there and walked out to attend to something, and left the ignition switch in the on position. More than one thing came up, I didn’t get back to the woods for a couple hours – and the battery was dead. Couldn’t get any of my other equip in there to jump it, so I borrowed a portable jump pack from a friend, and started it no problem. Finished up the day and parked my ATV in my shed. Next day when I went to start it again, it was dead again. Jumped it with the portable pack, then rolled into my garage where I have electric and put my charger on it at 2 Amp setting for about 6 hours. Started great, and started the next several times I needed it. Then it sat for about a week and it was dead again.

I had never had a problem with this battery before, including single digit mornings in the past 5 winters. So here are a few questions:

Do I need to charge it at 2 Amp longer, like over night?
Or, should I use the higher 10 Amp setting on my charger?
I guess I learned the charging system on this ATV is not up to recharging this battery in the short driving cycles I operat at.
It doesn’t look like I have access to add distilled water to the cells, and I can’t see the level in them as is.
Did I kill this battery for evermore?

And advice will be welcome, including telling me to give up and buy a new battery. I really am mostly impatient with this kind of problem, but would prefer to resurrect this one if possible.

In the mean time, I bought a portable jump pack that will save me from future borrowing requirements. It has worked fine on a camping trip over Father’s Day weekend with my son.

Thanks
