Install went very well. Waiting to test, need to wait for temps to warm up -15 degrees now.

I purchased the ecu flash, med comp. tsp head, and the Trail tech Raidiator fan. Bike runs awesome. So easy to tractor up wet rocky hills and has lots of power where and when you need it. Steve was easy to talk to and helpful. I highly recommend South Bay Moto and what they have to offer.

I definitely noticed the difference from just the re-flash to adding the head. Very impressive. The bike has a noticeable change in power across the RPM range but is not over bearing. Still very rideable.

Best $300 I put into my bike. It finally runs how it should have off the showroom floor. Idles, doesn’t foul plugs and has huge power gains in mid-top end. Riding is fun again!
