JSR Performance

02/17/2026

As some have noticed, we have closed the doors. John has decided to retire and just do dynos. We will leave our page up so you can send messages about scheduling dyno tunes if that is something you are needing done. Everyone that has supported John & JSR is appreciated more than you know. You have allowed John to do something he loves for over 35 years! His decision did not come lightly! It took months of thought & talks with family & employees. There will be an auction on February 25th at 9am at the shop. If you have any questions you can always call John’s cellphone or send a message to the page & we will get back to you as soon as we can!! Again, thank you to everyone who supported us over the years!! See y’all on the sand or at the race track!! 🏁

If you’re free on September 14th head out to Jeeps Motorcycle Club & watch some great racing! It’s sure to be a fast paced & fun packed day!! This is also the last SX race of the season so there is sure to be some good battles!

What are you doing on Saturday, September 14th? If you are in Wichita KS or can get to Wichita KS you should come out to Jeeps Motorcycle Club for the 25th Annual Night Time Nationals!!! It will be a night of Supercross racing you won't want to miss. If you are a rider, well there is some money on the table for the 250 Pro, 450 Pro and Vet 30 classes.

We have had to turn off our reviews at this time due to all the spam reviews being left! Remember, spring will be here before we know it & we will only get busier as the days & weeks move on so don't wait to long before getting your unit in here with us! We hope everyone is staying warm!
