Well I must be the exception , they built my last bike and I would never use them again . I had them do heads , cam , throttle body , pipes etc. He guaranteed certain numbers if I did everything he recommended . When I picked the bike up it ran good and had a lot more power but he wouldn't give me a Dyno sheet , said the printer broke . Rode it home 2 1/2 hours and when I got off the bike my base gaskets were leaking , called them and they said bring it back . Took it back the following week and they fixed it , road it back home and when I got off the bike noticed my rocker boxes were now leaking , called them back and Carl said the chrome was peeling bad on my rocker boxes it's not their fault he doesn't want the bike back , I said ok I'll have the local Harley shop fix it . Take it in to the local dealer and tell them what Carl said and told them to but new rocker box covers on and gaskets . They take my bike back and in a little while call me back and show me the rocker boxes are fine , no peeling chrome , they said the bolts weren't torqued down and he had used dried out cork gaskets , they replaced the gaskets with the rubber ones torqued it down and no problems after that , I had them pull a Dyno run and the numbers were 10 hp under what Carl promised . The bike ran great after that so I was basically happy at that point , Doug did try to make things right but Carl wouldn't let him , basically after Carl got my money he was done. I'd never use them as long as Carl is alive , Doug is a good guy.
