well?..he lives in watsonville, ca by the monterey bay area and the average elevation there is 23' above sea level soooo?.."elevation"...ain't the problem.
now what "could be" the problems is as follows...
1. No baseline stock dyno numbers were established so the bike may've been a pig to start with because of other HP stealing culprits such as...
2. Out of synch throttle bodies and/or possibly?....
3. Low milage?...as it is an '05 model....and if the odo still has qnything less than 10,000 on it?..the engine may not yet be "fully" broken-in yet...especially if it's 5K miles or less and?.....
4. If it wasn't an Eddie-Current type dyno and was just a standard DJ inertia type dyno they can be suspect to 10-15% variences from unit to unit...day-too-day...especially when tossing external conditions into the mix such as weather conditions to include humidity levels and absolute pressure and?...also...
5. Akro isn't reknowned for their "Top End Numbers"....as Ivan Akrapovic tunes his tubes specifically for "Across The Board Power Gains" to facilitate "Smooth Throttle Response" so?...if you don't have a baseline dynochart of the bikes "stock across-the-board" power curves?....chances are you won't see the true value of the "across the board" gains in living color...as in the streets?..."Peak Numbers" ain't shid...it's the bike that's tuned for quick "Elapsed Acceleration Times" and "A Crisp and Response"....yet still retains ..."A Smooth, Linear Throttle" in the meat of the engines rev range that wins the day....as far as "Sport-Riding" is concerned and...
