Actually asphalt has the most traction and is the hardest pull on any engine/transmission...hard packed dirt second...sand third...depending on the sand paddles you use...we use 8 paddles V-Cut which spin and slide easily...for play, not 10 paddles Straight Blade drag racing tires that really hook up...
We'll have agree to disagree, but I have rode all three on Quads for several years...BTW I jetted up thinking I would gain some Hp not true I lost 1-2 ponies...only makes 47 on dyno now was 49.7 with 168 main...I left it fat for longevity...
I'm not talking about traction, and I'm not talking about jetting up to make horsepower, superman, I'm talking about jetting up for sand to keep your engine alive. Sand has MORE DRAG on a motor, and MORE LOAD on a motor than any other venue. More than asphalt or hard-packed dirt - once intitial hookup is done on asphalt or hard dirt, it's done. As in most other venues. I think you must have confused yourself with what I said. I know I was talking about
the load on the motor, and not about traction at the tires, or any other kind of traction.
Sand is the CONSTANT drag on the motor, no matter what. You jet UP for sand, just to keep your motor cooler, just to keep from detonating (extreme load on the motor causes detonation), and JUST because of the load on the motor. Grab ahold of an old
Honda Common Service Manual, and check it all out - they fully explain jetting for different terrains, altitudes, and riding conditions. If you can't find one online (readily available for download), I'll give you a legal link to one, in case you don't have it, and I'll even point out the chapter/page you need to pay attention to in there. Best explanation anywhere, ever.
Believe what you want to believe - but now I see you reason for posting your
"Alba stroker on pump gas post" in the other thread - you're trying to sell now.
Post pics of your piston... Specifically around the edges...
EDIT - By the way... you have "50Hp" in your title thread, which is false. You, by your own admission, haven't hit 50Hp on this motor. You've now got a couple choices, and I think you know what they are... Figure it out, change what you need to change. Whatever.

Wonder how the Alba LTZ470 won the BITD two times with this same engine? Sand all the way... Wayne Matlock on board....this engine is bullet proof guys thats all there is to it....thats why we all ride one...
Just so you know - and everybody that rides "sand" knows this already... Racing a desert race on hardpack (most desert races) isn't nearly the same as riding in real "sand." Not even close. You even jet different for it. I've got my jetting specs for the two different venues, with motor specs to go along with it - if you'd want to hear those here...
Basically, what you're doing here is trying to sell a motor that you should have been running 100 octane in the whole time - whether you knew it or not - and you've only been running premium pump gas in. Hell, since you said you already did it in another post, and you said you called Alba about it, and you say they said to run 92 octane in it - I'll call them up and ask them. I already know what the answer is, because I've called them up and asked them before about it. No worries.
Get pics of your piston edges, that's the best thing you can do now... oh, and post them up. You've had detonation...
