Max speed is 51 mph gps
Something else is going on. That's less than stock. While I've been preaching that 16 gram weights are too light, it shouldn't impact your top speed that badly, especially with 28" tires. Curious to see the marker wear. Has your secondary been serviced\inspected yet?

250 miles on the machine. It’s had the 20 hour break in service. I plan on doing the same testing and posting with 18 20 and 22 gram weights. James at JBS is shipping me weights for free to test. After that I’m going to talk to Kyle at Weller racing to see if he would ship me a ECU with stock exhaust so I then can test with all the same weights but with stock exhaust.
The marker wear is in the 2nd video
Ok 3 more videos. I put stock sheave back in with 22 gram weights. Only got to 53 mph
wouldn’t work let me retry. Don’t know why this keeps happening
