Predator 500/560 JE Piston

Hi everyone,this is my first post and I have been following the forum for a while now.

Now my problem is this,I know my way around a predator engine but I am currently stuck,I build my son a really nice/fast quad with some mods that I personally did on the bike,engine and suspension,I am currently building a JE 560 BBK for myself,but this kit I bought from another guy that never finished this project before he past away,the Piston is brand new ,the cylinder is already correctly rebore to the size,I installed it and started it no problem,but as soon as the engine starting to heat up I can hear a knocking sound and becomes louder the more it heats up ,I suspect it is coming from the piston kissing the valves as it start to expand, I used the original OEM gasket ,was I suposed to get a thicker gasket with the JE Piston or do you use the Standard gasket?

The only way is to open up and measure or look for contact on the piston and valves,but maybe someone else already had this problem,I don’t know if they previous owner decked the cylinder,my son’s bike read 850 kPa/123 PSI with the 12,5 to 1 wiseco high compression piston standard 99,2mm bore ,running 95 Unleaded pump gas.

My 560 JE read 995kPa/144 PSI with decompression still installed,which I think is way to high and just for the the record ,I calibrate my compression gauge with a dead weight tester so it is 100%.

I did remove the decom. valve today to rule out noise from there, still the same,rechecked valve clearance ,Inlet:0.15mm ,Outlet :0.27mm, swapped cams with my son’s bike ,the head is standard 126,4mm.

Thanks for the help

1994 Honda 300 4*4 fourtrax

Hey guys. I’m new to this site and I need some help. I just replaced the starter solenoid on my 300 and it just clicks. I thought it was my starter so I tapped it with a hammer and it finally turned over. Now all it does is turn over, it won’t start. What could it be. Before I changed the solenoid I had to kick start it, when I had to do that it took me about 10 kicks to finally get it started and stay running. Idk what else to look at. Any help?

Sportsman or RZR?

A weird question, I know. So I currently have a Sportsman 570 SP for ranching and a RZR XP 1000 for play. I bought the RZR so my wife could trail ride with me. I have been building it to ride wooded mountain type trails with slick rocks and creek crossing. But she’s not into it. So now I’m wondering if I should trade it for a Sportsman 1000. The RZR seems like a big expensive unit for just me to trail ride in. The sportsman would be more manuvarble. I’m I crazy for thinking I should switch?

Serious Question, Really.

I can’t decide what 4Wheeler to spend more time and money on (and likely keep). I’d really like some stories and/or opinions. Are the 2001s and the like as tough and reliable as the early Fourtrax/Foreman?

My heart says fix up the 2001, sell it to complete the ’88 Foreman. My brain says fix of the 2001 and sell the 1988 Foreman. I really don’t have a need or storage space to keep both. Both need a set of tires so that’s a wash.

1988 – (Even I decide to live with the natty plastics)
Pro – Rides like a tank and tough as nails
Pro – A lot of time and $$ already invested
Pro – Runs well
Con – Still needs a lot of work and $$
Con – Parts less available and more $$$

2001
Pro – Parts available and relatively cheap
Pro – Already looks great
Pro – Carb rebuild and tires to complete. (Hopefully)
Pro – Has a pull start
Con – Is not a 1988 straight axle
Con – Does not run (yet)
Con – IFS (lot of moving parts)

Thanks.
