"The Famous Rzr" 800 Top End Rebuild 

Great Video and great work.

another excellent detailed video. Thanks so much.

Nice video, keeping it clean. Good work:-)

Very good video, can't wait to see him in it. Do you use a stone hone or bead hone on the cylinders, and also on the exhaust studs is it OK to use brass nuts? I am waiting until winter and I'm going to do the top end on the arctic cat 700 mudpro of my wife's. It smokes under throttle, so I am just going to freshen it up . again great video

I have a 2003 Suzuki eiger 400. Do you have any suggestions on what I can do to it. I'm trying to slowly make into a mud bike.

Holy crap what the hell did Nathan do to it 😂 good job on the rebuild

I got a grizzly 660 and it’s got a tapping coming from it been like that for 2 yrs is it time for a complete overhaul

Hay bud do you happen to know off the top of your head which one of your videos show you actually showing you seat the valves thank you

did you use new head bolts?

U just created a even better of a beast

Did you have to lap your valves? Thinking about reworking my top end and was curious.

In the process of rebuilding my 2002 sportsman with a 850 motor like this, is it a real pain to put those inner wrist pin c clips when your putting the cylinder back together?

when using the same cylinders do you hone it or use it as is

What was the cost in material for the overhaul?

hi i have a 2008 rzr 800 with a blowen motor hole in case and cylinder destroyed whats the most affordable place to find a replacement motor thanks for the inforative videos

I have a 2008 rzr 800 and am rebuilding my top end and found a wiseco piston kit and is a 10:2:1 compression ratio and a 76:50 stroke and 80 mm bore is this the oem size and compression ratio or is there any numbers on my engine that will tell me the specs ?

Was the big bore a noticeable improvement?

How many miles or hours did the engine have on it?

U ever done a top end on a rzr1k with the engine on the bike like that ? I’m thinking about attempting it I’m just worried about getting the pistons in the cylinder without breaking multiple sets of rings. Thought about putting pistons in and then connection them to the rods like u did but u didn’t show much of a pain in the ass it was lol

what was compression after new parts?

Do you need to worry about top dead centre doing top end rebuild

How many miles were on the unit when you had to do this?

How can I get in touch with you about some work

Looks possibly it was in water

Wow whoever owns that sure doesn't know what the word maintenance means

Aint that nate kid like 15 16? Needs to start caring about maintenance

everyone installs the pistons and never show how they do it.

Pos....wow. Total lack of maintenance
