guys
I raced Saturday at Cecil county raceway and air was at Corrected altitude 805 and Barometer was 29.32 so not killer but good air and I went 8.400 and 8.42 see time slips, how many 300 lb guys on a 500 lb bike can do this on Motor no power adder, stock injectors stock air box ecu tune, I am happy bike #159

Always runs the best right before they break . . .

That's a $12,000+ Carpenter motor with a billet crank,titanium rods,etc.,be pretty hard to break.

08 1441, head, cams, hand slider, and 7 over. So far 9.07 @ 152. Bike and rider 764 lbs. One of us need to go on a diet and I am guessing it will be me

just had it freshened in spring by Bob, and was spotless after 200 plus runs, good oil and keeping it changed helps, Amsoil Dominator 10w30 baby,

500 pound stock motor, pump gas, hand clutch, street exhaust 08 @ 63-1/2". I'm in the right lane, a gen1 ZX14 is in the left lane. DA was about 1700. I know the light was bad, but I was just trying to figure the bike out with the new gear and wasn't concentrating on that.

I wish I lived as close to the track as you Dennis. Doesn't mean I could even get near as good as you but I sure wish I could.

 

[sjg34]

I have a modified motor and I can't get close to Dennis on his. I am jealous

 

[Dennis]

Thanks guys. Practice helps a lot, and a lot of practice helps even more. Tomorrow is the last day this year for my track and weather looks ok so I'm hoping to get into the 8.80's. Sometimes trying too hard is my undoing though.

 

[sjg34]

Our last points race is tomorrow also. I made some changes to the clutch hoping to finally get my 8.999

 

[Brett Rahn]

Dennis what do you weigh, and how did you get bike to 500lbs, as mine with BST and TI winder is 512

 

[Dennis]

I weigh 160 out of the shower, so probably 175 suited. A basic Busa at 63" with an exhaust weighs around 515-520. I removed rear brakes completely, lithium battery, and aluminum subframe. I could easily remove one front rotor and caliper, and the oil cooler. That would probably be another 10 pounds. I don't imagine a Ti-winder is much lighter than my exhaust.

My other stock motor bike weighs 460 and went 8.53@ 158 last year on MR12. The 60' was better but the weight is a big factor.

 

[sjg34]

How much et and mph do you gain from mr12

 

[Dennis]

This is on a good (not great) air day. On a bad air day I get about .13 and 2 mph. My theory is that the bike is not tuned for it and is lean on a good air day so I don't gain as much mph.
