Hello everyone! new to the site but currently running 2 14s a 155" and a 163" rmk pro 800s. sleds are brother and sister and never separated, always running same hills and same powder, same polaris full synthetic oil, always maintained together. After some clutch rebuilds we started looking hard at rpm's and noticed were running closer to 78 and 7900 with high altitude weights (10-58). Compression test shows 101-103 across both sleds. surprised to say the least with just over 2000 miles and they both run so good. Full kit one and just top end the other? whats everyone think!
