George doing a burn out requested by Jeff.

George:  Good morning.  I have a few more thoughts to share with you today about my bike after riding 134 miles or so yesterday.

1.  Shifting / clutch action is simply amazing.  Unexpected improvement in shifting efficiency up and down.

2. Power, power and more power, all of it usable, smoothly and safely delivered. I was cruising in 6th gear @ 80 mph between Perry and Macon and decided to wind it up. What a shock!!  Before I could blink twice, I was at 105 mph and had MUCH more throttle left.  The bike would have just kept on pulling until I reached, only God knows what speed.  Thankfully I caught my breath and shut it down at 105 mph; which is fast enough for me at this time.

3.  Lack of vibration.  Yes it vibrates at idle like before.  Which you have determined to be a by product of the True-trac stabilizer.  However, prior to yesterday, my hands would regularly start to get numb after riding about an hour, and required frequent repositioning to mitigate.  I had  NO tingling or numbness in my hands yesterday after riding for almost 2.5 hours.

4.  Initially I worried about low speed riding in parking lots and executing u turns.  That fear proved unfounded.  The added power makes it easier to conduct low speed maneuvers at lower rpm.  I will continue to improve as I get adjusted to what I term, "new rpm requirements."

5.  Improved stability and traction ... is this possible?  As you know I had the True-trac stabilizer installed to prevent against possible rear wheel wobble.  This along with upgrading the suspension with Race Tech custom rear shocks and Race Tech Gold valve cartridge emulators in the front forks greatly improved handling over OEM.  What I experienced yesterday was amazing yet difficult to quantify objectively.  The suspension felt as though it had been upgraded again.  My bike felt absolutely planted to the pavement at all times and at all lean angles.  Traction was so improved that I felt as though my tires had spikes in them.  Is it possible that your engine upgrade work brought out the best in my upgraded suspension?  You are much more knowledgeable, please explain what you think ... or was this some "placebo" effect?

In summation, I am pleased beyond expectation with the result of your work, and thankful I found you and your company.

Thanks again

My 110 CVO Street Glide was a dud. I did some research on the internet on how to get more horsepower and torque. 

The Staff at Star Racing were able to build my 110 to a 113 with 140HP and140FPT. Wow!  It runs super strong from the day I got it back,
and after some 4500 miles I believe it is stronger now than when I got it back.

These guys built a righteous ride the only problem is my friends are pissed at me because they can't keep up.

It's lonesome out in front!

Thanks for the awesome work!




Hey George this is Kristen from Connecticut, with our 107 Thrasher kit, people are loving it.

Guys at Harley are all excited about the horsepower on your head work. Hope it gets some work your way.

Thanks Chris! Good job!

George finally got chance to do a little riding, I love the way I can cruise just like a stock bike.

U would never know the power or torque upgrade until u twist the throttle. U were right more smiles to the gallon.

Thanks for the good work. Love the way it pulls past 6000 rpms, the old one started to fall off at 5500.

World of difference. Exactly what I was looking for, cruise all day, but can pass just about anything when u want.

Keep up the good work, take care and good luck. J
