106" TWIN CAM TESTIMONIALS
106 CU" TESTIMONIALS
Dear Bob, Robert, David, Angelica,
               Incredible! That is how I would describe my Johnson Engine Technology upgrade on my new Harley Davidson Streetglide. I now have a machine that turns people's heads a block away! The sound is awesome, the power is everywhere and I'm getting 50 mpg! My bike runs cool,smooth and my adrenaline pumps everytime I twist the wick. The Baker transmission kit is the way to go on Harleys new 6-speed and the Rivera Pro-Clutch is awesome.
                Bob Johnson is a true professional whom went out of his way for me because of some factory electronic problems. He even took my new bike to a dealer up there on his own time for a varity of warranty issues.  Johnson's is a classy, professional, must have perfection shop. These guys are not just engine builders, but engineers of the highest standard. Johnsons standard is reliabilty with incredible performance.
Sincerely,
Brian Tinman

First Email:

I received the package (take off parts/paper work) the other week and just wanted to say thanks.  After seeing what came out of the bike I am even more impressed.  I've put about 2000 miles on the bike since your rebuild and my wife and I recently took it up to Skyline Drive.  Two-up and with luggage the bike cruised real nice on the highway at 70 to 80 mph and pulled real strong in the mountains.  Curious to see what you guys come up with for the new 96 inch motor.  Well take care and thanks again.

Second Email:

I have put over 3,000 miles on the bike since you installed the 106 package and it is running great.  I took the bike to Key West in January with no problems.  Just wanted to touch base and let you know I am very happy with the engine and transmission work.  The jury is still out on changing the pipes... I'll let you know.  Take care and thanks again.

Third Email (8/20/07):

Just wanted to thank you again for picking me up at the airport and for a job well done.  After riding the bike home - I'd say I couldn't be happier with the new set-up.  The pipes sound awesome and drivability of the bike is great (I didn't know what I was missing).  I could actually hear what the toll both personnel were saying.  The bike got about 45-47 mpg on the trip home and the oil temp was about 220 degrees with me running between 70-80 mph most of the way. Great advice on timing.  I got to my hotel at the Delaware Memorial Bridge at about 11pm with several stops for food and to stretch my legs. After a good night sleep I had a leisurely ride home on Route 13 through Delaware and the Eastern Shore.  Perfect weather - no rain.

Pete had J.E.T. 106 custom engraved on his timing cover...I think he likes it :)
 

Hi Bob & The Team At JET
Just a quick note to say Thank You for the job well done, and fast. I took the bike out for a road test the day I got it back and Wow just in that short ride I can tell I am going to be very happy this coming season.  Even though it was cold outside and getting ready to snow that day,  I quickly warmed up when I took off on the bike. 

The heck with snowmobiling this winter, bring on the spring & summer riding weather.  I am ready to go until next fall & winter when I come and see you again for my next upgrade to this bike.  Maybe the wide tire kit.  Hopefully I will be satisfied with this 106 cu" package and not want the 116 cu" package...yeah right.
Happy New Years & Thanks

"WOW! I put 100 miles on after we picked up the bike. I can't believe the overall improvement in power as well as overall ride-ability. As you know it's been hot and the motor runs and starts better than ever!
I trully appreciate all the little extras that you suggested, like the pro-clutch and transmission work. The power get's to the rear wheel better than ever.
I appreciate your follow-up call yesterday, but Christi and I decided to spend the day riding to Cape Cod and back. We put on 260 miles in heavy traffic on a really hot day with no problems just a smile on my face. I was amazed how easy it was to accelarate on ramps and passing traffic at 65++ MPH with two of us on the bike with plenty of throttle left...
I asked you to give me the ultimate sleeper and you did. No one knows the bike isn't stock 'till I roll on the throttle and leave them in the dust!"

"Dear Bob,
      After the purchase of my new 2003 Screaming Eagle Deuce, I was disappointed in the performance of the motorcycle which included a Harley Davidson factory installed Stage III Big Bore Kit.  Thankfully, you and your crew had spoiled me with the work you had done on my 2000 Deuce.  I knew I could turn to you for help.  Now my limited edition bike looks factory, but runs with 125 ft/ lbs of torque and 110 HP.  As you told me "Make sure your bike is pointed in the right direction before you hit the throttle.  See you at the 1000 mile service.  Thanks Again."
