Finally had some time to get a video of the bike an it's mini first gear power wheelie. It didn't do these with just the 103" upgrade... but it's character changed entirely when the stock sprockets were changed.
Original front sprocket: 30 tooth, replaced with 32 tooth
Original rear sprocket: 66 tooth, replaced with 70 tooth.
It is now geared much lower than stock, too low as in 6th gear at 70 mph it is turning 3,000 RPM where it used to be I think about 3,000 RPM at 80 mph.

Anywho, all that is necessary in first gear at about 5-10 mph is just whack the throttle open, no clutch action, and up comes the front wheel a few inches....

I'm to big a sissy to try it on my scoot... but I love it....

 

+1 But it's Cool !

 

That's really pretty cool, now all you have to do is kick it into second on the way up to keep it going.

 

thats 100% awesome.

 

lol that's awesome, Centerline.

 

That made my night. I love that ****

 

That's awesome and sounds good too!

 

I did the evo 30 tooth and woods cams and it will pull the front easy'
I have s&s 106 kit waiting on heads and then it should rip.
spence

 

Just curious....
You sure about your tooth counts?
According to your numbers you only changed from a final drive of 2.976 to 2.960 adding teeth to both would negate any real gains in gear ratio.
