Ran into a guy yesterday that said he dynod 56hp with fat jetting. What does it take to get that kind of power? can it be done on a stock bore and stroke? Thanks, Tim.

 

I've seen dirt bikes in the mid 50's, but not a quad.

 

i have seen 60hp from a 520 trx from n motion kit

 

i have a buddy who dynoed his 500r with port and polish, CRF carb, everything you know...... and pulled out 59 HP, so you probably can't get it without a bore of some kind. Just on a note, my friend's dad has a HP research DS 730 that dynoed at 73 HP...

 

The N Motion kit- does it sleeve your stock cylinder or do you get a new one? The question is does the cylinder still look stock with their kit?

 

stock 450r 2wheelers are 54 hp quads are around 38 hp. i dont know the difference in the bike and quad motor but it has to be somethin major for that big of a gap. possibly some loss in the drivetrain of a quad?? i imagine it would take a bigbore kit cam carb and exhaust to see that kind of power from a quad. ive heard the hrc kit bumps the hp to about 43 on the quad.

 

You got to love 2 strokes

one reason the bike shows so much more horsepower is becasue of driveline loss. The bike only has to spin a small ammount of weight in the rear compared to an atv.

 

You get a new cast cylinder. I have no idea how close the new cast cylinder matches the original one.

 

I dont think you can get 56 HP from just that you will have to have more upgrades to the motor to reach it..
