I finally got a chance to oper her up and it wants to bog out once you hit about 50 and punch it, it will climb to 80 but not much more. It seems once I get past 3/4 throttle the rpms drop from 8000 to 7000. Any ideas? Im thinkin belt or plugs hopefully.

Ok so I got ahold of the guy I bought the sled from and he tells me that its clutched for racing so its all low end. Wouldnt it still hit max rpms or at least over 7000?

If it dropped (key word) from 8k to 7k that shouldn't be the case.
