i was at chapmanville this week getting a 2004 pred and trx450 dynoed , nice and friendly shop, but the numbers seem a little low. have you dynoed your pred/trx, or do you know what the stock bikes run on this dyno.
ps...a/f was good

pred-pipe,after market air box...32hp

trx450-pipe,sparks cam,open air box...32hp

 

I was told the Pred is 38-42 hp stock at the rear wheels. I don't know but it seems low to me. I think the Scrambler 400 is 38hp stock and I know I have more hp then they do.
