What oil is best? and what ratio?

[skidooguy]

I put many miles on a trail boss 250 @jake wells it wasn't very reliable but it ran great for short periods of time. Is yours oil injected or did you make it premix only.

it was oil injected and reliable other than flat tires and having to replace a worn out drive chain.

I had a 6x6 like that. Except it had a 425cc engine IIRC.

Says it's reformulated ope oil.
Nothing about boats. It's premix only I believe

I did a little digging and royal purple is indeed a ashless tcw3 type marine oil. I would not use it in saws.

Just tore a engine hoist down to clean all the hard grease out and refresh it with new, It was full of that stinkin gear oil smelling grease. Done washed my hands three times with hand cleaner and others and still smell it.lol

The air strykers in my experience need a lot different jetting than the normal carbs. Especially on the needle and mains. Who was LRD?

This has been my expiereance as well. They have a much stronger signal than a standard PWK.

Are you going to run 2 r in dunes?

Yes, and without reservation. Especially so in my 500 as it makes peak power at a paltry 6500 rpm.

I had a opened bottle of gear oil leak out a little in my car trunk. Months later it still stinks like it.

The 500's are the diesels of the dirt bike world.

What problems can it cause?

I had a std 39 pwk once ,on the 250r it never ran near as good and easy to ride as the pwk carb
I looked on my shop wall for needle specs ,i painted over them when i repainted my paint booth room
DEJ or DDJ rings a bell though the taper was kind of lean so i had to run in the 4th clip from the top .

the si7 smells worse than h1r but si7 has a pretty blue color when mixed.

Nope.

Holy chit! Can't believe this thread is going still. Big thanks to all those that have been testing.

I haven't looked at this thread in 6 months. Have we come up with a top 5 yet?
