If your plumbing snake can heat that pipe up cherry red, go for it.

Got the head put on. Had to order a gasket kit for a JR50 as the KFX was out of stock. Lol

I cycled it around 2x to make sure the piston wasnt going to touch the plug, then bam, first pull it lit right up. Blipped the throttle a couple times and it certainly seemed zippier. Even sounded better. Tomorrow I may have a chance to take a spin before I get the kid from daycare.

Will take a look at the spark arrestor/exhaust insert in the muffler when I get a chance too.

after the head work and removed the spark arrestor. Played around with which set up felt best with the silencer core/cap removed ect. Think it felt strongest with the guts out. Will try to burn out the pipe Friday

little before and after. Pretty clear how quick it hits top rpm and higher revs too

Do you think over oiling from the injection system can cause tough starting cold? Ive been running the quad a lot with the rear end in the air which lets the axle spin freely pumping oil like crazy where as if I had it on the ground, the oil mix would be greatly reduced. Quad runs great, easy to start warm, but after sitting a week, its brutal.

i just filled the oil tank with Amsoil Dominator when I got it, I was hoping to make it through the tank before switching to premix. I guess no harm in transferring the tank oil back into the bottle
