Racing 450's discussion

[JoePA]

So in the end we come up with what?? The 4 poke just has us beat at certain things due to design. Thats ok, for me anyway, because when they get their ass handed to them by a machine that is well over 20 years old that can't put the power to the ground, a rider with a grin from ear to ear and the sweet smell of pre mix in the air is worth every bit of ridiing the R. If we lose then we still have a grin from ear to ear and we go slow through the pits so everyone can enjoy race fuel and Castor 927.

Ryan, I think we can do the best we can with the quads we have, no matter what engine size, by riding our asses off and being so comfortable on the machine that we strive for a flawless and fluid lap. Luckly we aren't at the pro level and they/we get tired quickly so lets focus on the fitness side as well.

Or as mentioned lets go get a 4 poke and hit the krispy cream on the way back after McDonalds!! I can't lie though I will someday have a Hybrid as those machines are sick!

^^^^ Fitness and perfect laps will make the biggest difference on a 2 stroke... No joke.  Is till dont think i have gone a perfect 5 lap moto without a mistake on my R.... Frusterates the heck out of me....

Let me throw this out there.....do you go big, big bore and run a flywheel weight to be more 4 stroke like power?

I have often wondered the same thing.

[Burns363R]

a heavier fly wheel wont give you more tq.  it will smooth out the power and make the engine rev slower.  But it wont give you any more tq to power out of corners with.

[The_Steve_Man]

Do the powervalve cylinders give more low end grunt? I know going bigger is the major factor.

[89Longrod]

Yea I remember reading the power-valve motors are great until a certain cc then the gains aren't as noticeable. Maybe one of these other guys know the exact size cc that's max for a PV to still be worth is. I thought it was somewhere around 33-350 cc's.

[Burns363R]

I had a ESR 330 PV engine.  It pulled really well down low but it had such terrible over rev that i couldnt stand hitting big jumps with hit.  It seemed that i always would need to shift going up the face of a jump.... Granted my 330 was just a TRX9 port job with a 205 psi compression.  So it wasnt a crazy engine, we wont even talk about reliability.

And help reduce stalling in the corners, one more way to help reduce the mistakes.

Like everyone has already said it is hard to beat the new 450's.  That being said I watched both my brother's over the years beat them every weekend.  But they practiced like nuts and worked out alot.  Not a ounce of fat of them.  And that is when they had 265pv's.  One a Duncan...the other a LRD.  Then after we got the Duncan 340pv it was easier to beat them and you were not as tired by the end of the race.  I ran this quad a couple years and it was a blast.  We also have always ran 15/37 gearing with 18" Holeshots.

[05450r]

And thats the thing, theres so many variables that factor in between. I know I would be faster on a four stroke, but throw an older pro national rider on a two stroke and get schooled..lol

You guys ran 15/37 gearing on the 265pv also or just the 340pv?

Just the 340pv.  We usually ran 14/37 or 14/38 on the 265's.
