2002 Warrior freshen up

[MidwayUSA]

Didn't have any luck selling the Warrior so here I go sinking a little money into some preventive maintenance. First thing I did was pull the filter to make sure there weren't any chunks. All was good there so tear down began.

Top end torn down and inspected. All was good so time to proceed. Here I had already swapped in the new timing chain and cover back on:

Nice used White Brothers Arias piston standard bore:

I glass bead cleaned it then knurled the skirt just in case the bore had some wear. Now to deglaze the cylinder and hand sand the knurl till the piston will slide in the bore:

I have posted pics of this head on here before. This unit will be assembled with stock valves, springs, used cam, new seals and installed:

Thanks guys. I was so fired up to get it done that week, the camera was the last thing on my mine. I had to deal with my son's spelling homework and get him to bed. Anyway about 11:30 that Monday night I got her all buttoned back up and running again. I rode Saturday and Monday (Memorial Weekend). Runs great and definitely a power increase. Problem now is I need some better fuel. It ran fine Saturday, but Memorial Day it was pinging a little under load. I mixed Blendsall in the fuel, but it was only 87 octane so apparently not enough.

The real test will be our dune trip on June 22. I switched sprockets on both ATV's to gear for the 22" sand tires. All that is left is to change the oil and filter in the Raptor.

I will post pics from the trip when that time comes. I'll try to do another short video too. Going to get another flash card for the camera since I filled it up last time.

Damn, nice work. Whats the deal with the piston skit again?

And whats Blendsall?

We have a piston knurler at work. Its an old school thing from back in the days when people used to just re-ring and reuse the pistons. If the cylinder was slightly worn, you could knurl the piston then after honing the block, sand the knurl down till the piston would slide in. The knurl holds oil and keeps the piston from slapping around in there. My cylinder wasn't worn much, but I knurled it mostly for oil retention.

Search out Blendsall (not sure if I spelled it right) on Google. The dealer here sells it. It is an octane booster/upper end lube. Can be mixed at different ratios for 2 and 4 stroke engines. I think it uses castor oil as the upper end lube and it smells like race fuel when it burns. I started using it in my Banshee rather than buy expensive race fuel.

Knurling the piston... now there is something you don't get anymore. Like resleeving Vega engines. My dad had a friend back in the 70's that would knurle the cylinder sleeve to ensure a good tight fit in that aluminum block. Resleeve those engines and they were actually very good. So I've been told.

We don't knurl much any more. Use to do it a lot years ago even after it wasn't the norm any more. The old Warrior was kind of noisy before I tore it down. I didn't know if it was piston slop or not so just covering my bases. Forged pistons actually knurl quite nicely and the knurl holds up pretty well. Not so much so on cast pistons.
