Lots of power and damn reliable.
Make sure you inspect all parts.It went together well, no issues after other than valve lash.For anyone wondering the ring gap is pre gapped.I’ve put about 55 hours on mine with no serious issues other than the valve lash nut falling off but that’s my fault

Good product
Had this put on my 2001 warrior 350 and man it has some compression the starter has a hard time turning it over with my little battery may have to look into one with higher cranking amps with a jumper box on it fires up no problem. And man does it run good. May need to get a better clutch slips alittle when I'm pulling a hillclimb in 6th gear. Highly recommend this product.

Tons of power! I’ve bought two of these now and Love the power
I put this on a 95 Yamaha Wolverine 4x4. After installing this big bore kit I’ve noticed the power!I have a 2003 Wolverine stock 350 and this one blows it away, once the 03 needs a top end I will be buying this one. Awesome power at a reasonable price.Just bought a second kit for my 03 wolverine.Works great! Brand new machine! Definitely recommend

Awesome replacement!
Bolts rite on and comes with extra parts that are not really required. I suppose if you need the reassurance of liquid gasket material supporting your real gasket they would make sense.The trick is to seat the shaft, gasket evenly then align the head over and torque it all down prior to tightening the port side Allen bolts.This Cylinder is practically the same price as a replacement, made sense to me to beef up and boar.

Save your money buy another kit.
Very poor customer service and cheap parts. All you will get is the same automated email when contacting them about issues.

Comes with alot but not everything
Fast shipping but helps I'm in the same state everything looks to be good quality they send just about everything plus thread locker gasket maker but one thing they don't send is the head dowel pins would have nice to know meaning it was in the description as it replaced said oem part 99530-14016-00 which is weird because when you search the part number this kit comes up kinda a bummer I gotta wait for new ones now before I can finish the install
