| The db1 Beta EVO MKII ready to rip the dyno a new one. |
After all the work done to the Beta EVO we finally got her back on the dyno at RBimports in Caringbah. The new exhaust pipes certainly have done a wonder in the mid range, and completely eliminated the shocking hole in the 5800rpm range. As with all tuning you can not gain without sacrificing somewhere else. In this case the bottom end under 4000rpm is now a bloody big hole.
Ouch. I don't think the bike will like being a tractor off the line anymore!
The big bottom end hole is more than likely caused by the really large header pipes. With an internal ID of 48.5mm its probably a bit big for the 800M. Still the extra midrange is welcome.
Here is the dyno graph, blue line from the old 2into1 and red from the Beta Mega Pipes!
