Don't Just take our word for it...Hear what other people have to say about the MasterTune.™

The MasterTune worked fine we just kept dialing it down until it slowed and opened it back up and that was it. I would recommend it to everyone, we had no trouble installing it. Thanks for your help!

George, Used the Master Tune in the IKF road race this last week end and worked great! Our local engine builder was very impressed and the two I pitted with asked for your info so I hope you'll get some more orders. Thanks, Bill, 2002

Hi George, I want to let everyone know that Master Tune is a great option to have on a kart. We have been using one for almost 2 years and it has worked without fail....I don't even own a jet.Master tune is not just a tuning device but a hassle and time
	saving device in the pits.......NO changing jets at the last minute etc. with all the mess and fuss. We just keep track of how many turns at what time of the day i.e. air density and go to the grid.......if we got it wrong the race is not hampered by the wrong jet choice...just make a tune adjustment, just like the thousands of 100cc racers do. We had a rough time at the World Super Kart race at Laguna with major motor breakage (cylinders cracking and pulling off the cases) we had our hands full trying to put motors together and breaking in pistons.........missing hot lap
practice time etc.this resulted with no jet data at that track......no PROBLEM we set the Master Tune to a safe setting and let the driver go from there. We had very very little practice but still finished every race lap both days and finished first on Sunday........that would have been much more difficult without the MasterTune ...... THANKS GEORGE.

George, Dave here, just wanted to drop you a note. We had our firstrace this last sat for region six road race, the rotax 257 perform perfectly also using the master tune made tuning a breeze as you said when your out in front by a mile or in my case ½ a lap or ¾ of a mile fatten it up a touch to save the motor, well again thanks for such a get product in the master tune and your set up on the rotax.

Thanks George,

No more changing those blasted main jets all day long and no more arguing with my wife about which jet to put in! Life seems bright right now. ( laughing ) Steve Matotan

Hi George,

Thanks for helping me out, I think I can get this thing in the range with the jets your sending. I must say, your customer service is outstanding. When I first e-mailed you with my problem, I didn't even give a phone number for a call back, but still you looked up my number from the past and called me. If I was in business, this is the way I would try to treat my customers.
see ya, Steve Matotan

George:

Thank you very much for the parts you sent me. I am very impressed with the MasterTune unit. I build turn-key laydown 125 karts and from this point on, I will not sell one without a masterTune on it! The tuning is so easy and positive, you can literally control your temperatures within just a few degrees. If a driver is serious about being competitive, he MUST have a MasterTune!

Thanks George,

My Son's name is Kyle Schreiber, he is 20 years old and is one of the fastest, and the best kart drivers we have in the Midwest. Send a MasterTune decal, we would be glad to endorse such a good product.

Hey George,

I just got back from the WKA nationals at Road Atlanta and I ran your MasterTune during Sunday's race. It worked really good. I finished 4th, and with a little more experience with the adjuster I am sure I could have done better. Unfortunately, Friday's practice was rained out and I only had a couple of sessions to try it out. The 44" long worked great. Thanks for your help.
Bob.

Thanks George,

Turning the blue knob to tune beats changing traditional jets all weekend any day!

Very impressed with the Master Tuner - east to tune and great design. There is picture of me and my 250cc kart in the Sharp Shifter website - under WINNERS.
