    Lots of people blamed the Rd reflashes for blowing engine for a while. I think that often exists between the bars and the seat. No matter what the salesman say, you should be monitoring afr's, engine temperature, looking at plugs and all the little things that help keep a engine together. An ecu is hardly a swap and ride.

    Rd always tells me 12.5 for AFR, sounds like a good way to sell pistons to me. Sure 12.5 is optimal power, but when your only reading an average of the 4 cylinders. 11.8 is what I shoot for, as recommended by reliable sources from here. Wiggle room, gotta have it.

    Anyyyyyyways. Im sure I'm offended some people...I'll leave now.

    You don't offend me in summer months I just don't feel comfortable running anything higher than 12......in the winter months I may let it go to 12.2-12.5 colder water and air motor should not run hot enough for it to be a issue, plus it's often to cold to run 80+ in October and in April for a long period of time anyways.

    Funny how the pump is no good yet Dean's Team rider Abdullah Al Fadhel won both Pro Open and Pro Limited titles with this pump. Maybe the pump is only as good as the impeller inside it?

    What's your point? Was the race 30-40hrs long?

    im sure people could care less what a salesman or a riva sponsored rider has to say about the pump.its recreational riders that are having issues and they arent trying to push a product.you cant argue or justify the majority having mostly negative results.it is what it is

    Agreed. Plus the rec riders dont have multiple pumps to swap between at the drop of a hat.
