Dyno with 1/2 Exhaust?!
Hey everybody. Long time listener, first time caller here...
I finally got the '04 Hayden RC51 of my dreams last fall and have spent the winter doing a few things I had always wanted to do... Included on the to-do (done) list is a Ladybird GP exhaust (Simon - wow!), flapper-valve and PAIR removal. I installed a PCV and am in need of a dyno tune to get it running right.
I went to the dealer a few weeks ago and waited for them to make half a dozen pulls on the thing before telling me that their dyno wasn't providing HP or A/F data. They installed a map from the Dynojet site for an exhaust the guy claimed was "similar." The bike runs worse/weaker than it did before I went.
I got a call back from the dealer today stating that they had remedied the problem with their dyno and want me to come back in to get the bike sorted out. I asked a few questions and the guy told me:
"We just have to find a way to block off one of mufflers so we can get a solid A/F reading from the other one."
If they remap the PCV to ideal values with one of the mufflers blocked off, won't it just be too lean again once unblocked? My mechanical know-how isn't 100%, but this doesn't make sense to me...
Any advice/clarification you guys can offer would be greatly appreciated!
Hopefully this isn't a redundant question; I did try the mystical "search" button.
