Rollin' Thunder Dyno Service

 is owned and operated by Wayne and Lisa Engen in Farmington, AR.

RTD was formed in NW Wisconsin, and was moved 
to Arkansas in the fall of 2016. Wayne has been involved in the Performance 
industry for 25 plus years. Experiences come from a wide range of 
applications. He has supplied many dirt track stock cars with engines, some 
of which became national champions. He has owned motorcycles most of his 
life. His Harley bikes are what got him interested in tuning them. With many 
trips back and forth to various shops with little success, it was quite 
apparent that northwestern WI needed another motorcycle tuning option. 
And after attending the BBB event in northwest AR in the fall of 2016, Wayne 
& Lisa decided a warmer climate would be a much better fit for both them 
and a motorcycle shop. It's Wayne's mission to make sure each and every 
bike he tunes get the attention needed to be properly tuned. There is no 
rushing anything through for any reason whatsoever.  Feel assured that 
your bike will be tuned to the best it can be tuned when it leaves RTD. And 
there is no discrimination at RTD. Wayne will tune Harley, Indian, Victory, and 
metric bikes. Come see us and let us become a part of your riding

"This shop is awesome. Goes the extra mile for their customers, by far! And even if you're bringing in your bike from out of town, this shop is willing to work with you. If you own a HD Night Rod Special, these guys will tune it without hesitation and will explain every detail of your tune."


"Wayne is very knowledgeable on the dyno and tuning. I will never go any where else for tuning. I wish I would have seen him first before I went to 3 other places to be disappointed. Waynes tune blew the others out of the water, it was like a complete different bike!"


"Best bike shop ever! RTD was able to things to my bike nobody else could. Fixed my my carb after engine work and new pipes left it flooding. Nobody else could fix it. Runs GREAT, now and sounds great. This is the only place that will ever touch my bike again!!!"
