If you're seriously interested and/or willing to buy new headbolts then I have no issues with that. Heads are 487x's. I'll have cam specs later today. Honestly it'll be within 50hp crank of the mark. A little more breathing room with 210cc runners would go a long way on it. Of I remember correctly the heads on it are 170cc. The "X" designating slightly larger runners.
Like I said serious inquiries are more than welcome to it. I just need the thing gone and a DD. I'm willing to loose thousands here.
