From a rolling start, my F4 took a 2003 v-rod vrsca with ease. +2 teeth in the rear, 520 did conv, K&N intake, yosh RS-3 slipon and dynojet stage 1 kit. The owner of the V-rod kept blabbing about 120hp... drag harley, fast.. blah blah blah. No dice.

 

Thats the point... Im going to buy all those things .. but in reality HE'S going to be buying them for me ...
all I have to do is donate a quarter mile of my time ... ahahahah..

 

lol... that's a good way of thinking about it. hey man! i'm kinda stoked to see that video man. be sure to keep us updated... and try to make it sooner, maybe like 2 weeks sooner?

 

Its a harley against a CBR, your gonna win easily, hands down. I dont care if he has 150 hp, his bike weighs twice as much as your does and last time I checked the F4i has more that 1/2 of 150 hp or 75.

 

So who won?!

 

Not happen yet my friend ...... But when it does I will be sure to have my wife record it and I will put it up on here .....
all im doing is waiting for him to finish his mods....
I WILL BE SURE TO SHARE ONCE IT HAPPENS .....

 

108 to the crank.

 

I have seen a weak run on an F4i of 85hp, but most of the bikes were running 95... and I did see one pull an honest 103hp (all on the same night, same machine).

You've got a serious weight advantage - and you've also got a serious gearing advantage. You'll pull to top speed in 3rd, maybe 4th on that run. First gear can be ridden out in literally 2.5 seconds maybe 3 seconds.

If you get a good launch you'll be fine.

Have you ever launched before? The trick to a good launch is re-understanding how to use the clutch. In the MSF they say it that the throttle controls power, but the clutch controls power to the road. That's about right. You want to keep the engine in the nice meaty part of the power. As you slip the clutch out, keep the engine in that meat by rolling on. Keep the front end on the ground with the clutch slipping. This way the engine doesn't bog down and then have to catch up. By the time you've got the clutch fully engaged you'll be crossing 60mph and desperately looking for second. No wonder people love pulling away on sportbikes

Either way - the lower weight of the cbr will make it much much easier to launch quickly. The question really is - does he have enough torque to pull past you at the end of the run. That becomes a question of gearing. He might make more hp than you, but what is the width of usable power? He might not have enough gears to stick in that band of power. Also - he doesn't have a full fairing made for this... he should top out long before you.

 

+1...good luck, be safe.

 

You shouldnt have a problem... Just shift high 13.5-14K ...
