1)the warrior crank is a single pin crank. You can replace the pistons by removing the jugs and heads.

2) Yes, cylinders are coated with Yamaha's version of Naskil, Nikasil, or whatever it is called.

3) So far there have been no reports of premature ring wear, and there have been several warriors with 20k+ miles on them.

4) The main thing you need to check is if the warrior you are looking at has had the required tranny recall done on it. If it hasn't, it must be done. One advatage of it not being done yet is that you can replace the pistons at the time of the recall for no labor charge.

 

That's what I call one stop shopping. Thanks Dice![8D]

 

if it helps you decide, with 24k on my bike going into recall, new pistons went in and old pistons came out. The old pistons look pretty much new, I was impressed and hope the ones in there now look as good at 50k

 

Machman,

There is actually a plus to buying the bike prior to having the tranny recall done. Like Dice said, you can get alot of engine work done for a relatively cheap price. This is because essentially they have to pull the motor apart anyway to get to the transmission. So you save a bundle on labor. This gives you the ability to add high compression heads, or any other performance mod you can think of: speedstar kit, big bore kit, etc, etc. Not necessarily a bad thing.

If the motor has high mileage on it, think of it as having the opportunity to have the engine rebuilt with a bunch of high performance parts for essentially the price of the parts.

I know that this wasnt exactly your original question, but hopefully it helps.

machman....follow the above link I took pics when I replaced my pistons...Might give you a little more help

The WIZ

 

25,000 miles and my pistons looked great when they cam out at recall. HC pistons looked better.

As I've said before, Get a service manual, it is a big help when doing any work on your bike.

 

This is a very roboust bike. I wouldn't consider 20,000 miles high mileage. So far on this forum there have been relativly few problems with this bike considering the number of members. Good luck and have fun with it.

 

This is just the kind of info I'm looking for guys! The bike I'm looking at has already had the recall done, but I'm thinking that with an easy dissasembly like the Warrior offers, I could do alot of this myself which will save tonnes of cash...

Thanks!
