I started with the Dyno yellow stripes but there were a little too stiff so I’m gonna go with the greens.Dover reds, Dyno Green Stripes and the WMS Tuck and Run springs are all top choices. Pick one and go!
Yep. Pick good springs.Dover reds, Dyno Green Stripes and the WMS Tuck and Run springs are all top choices. Pick one and go!
You must certainly do so! Our little Jr3 motor spun 6950 last weekendYep. Pick good springs.

Us too... apparently the finish line is several feet BEFORE the flagstand there.... it was a photo finish for sure!I thought for sure he had the pro race won.

We definitely wasn’t gear bound. My son turned the fastest lap in that class and led quite a few laps. This particular track has a ton of drop in the corners and No bite so unfortunately you have to spin em a little higher. Although i ended up dropping a tooth for the main and we stayed around 6700 all night.6950 and we’d be gearbound for sure.
Our engine fell off bad at 6500. We were turning 6550 one day and we couldn’t keep up. Dropped one tooth and we were back in the mix.We definitely wasn’t gear bound.

Even if you get pre set springs for your engine you still have to check them to make sure they will be legal for your rules!I’m building a JR3 motor and I’m wondering what would be the beat valve springs for this application?
Because I don't pay attention, I had no idea who the motor was for when I built it. I was glad to hear it was for you guys. You all made it look good.You must certainly do so! Our little Jr3 motor spun 6950 last weekend
Could be kart and tire issues. The worse the kart and tires are, the lower the rpm will need to be closer to peak power rpm to be fast. As the kart and tires get better and absorb less power to run a given MPH, the further past peak power you can turn it and still be as fast or even faster. Then there is the motor........6950 and we’d be gearbound for sure.
is that being said if you are on the right gear to begin with?Could be kart and tire issues. The worse the kart and tires are, the lower the rpm will need to be closer to peak power rpm to be fast.

The right gear depends on how the kart is rolling that day. Different setups and tires require different rpm to be fast with the same motor.is that being said if you are on the right gear to begin with?
