So get this! My dealer was telling me how they took out 2 2010 dragon 800 for testing. Sled #1 800 163 w/ 62 gram BB weights and otherwise stock clutching. Sled # 2 800 155 w/ 58/38 helix otherwise stock clutching. Both have been geared down to 19-45. They could not pull above 8000 RPM's with either setup. They dropped weights and found no change in RPM. They then dropped in 10-64's in each sled. As I understand the story, this made the sleds RPM's raise to 8300-8400. They said they flat out ripped with this setup. Sled #2 had the skis in the air all day long after that. They then threw an SLP single on sled #2 and said it was even more impressive. They were even thinking about trying 10-66's just to see how they performed. I realize that with lower gearing you can run heavier weights, but it doesn't make any sense when you apply logic to this. Has anyone else tried throwing MORE weight at the primary? I'm curious to ride my twin piper this weekend with the 62 bellybusters and see where my R's are. I put in 10-60's last time just to maintain my r's with my break in tank, sounds like I wasted my time. FYI, testing was performed at 7000 ft on a 25-30 degree day
