Low on top end power

PRAY BEFORE RIDING
Round 4 - Valves adjusted - so its Low on power, injectors, fuel pump, o2 sensor ?? 2001 like new still in the Family with 30,000 miles120116393_10221179535817089_514966618180407260_o.jpg
 
What is the bike doing that leads you to believe it is low on top-end power? Other than the recent valve check, do you have a service history on the bike? Has the bike had a thorough service other than just the valve check—new plugs and air/fuel filters, fresh fuel with a dose of BG-44 injector cleaner from NAPA, inspection/testing of plug wires, etc? Has the large branched vacuum line running from the throttle bodies down to the crankcase been checked for cracks or breakage? More info might get you a more targeted set of suggestions for things to check.

Best,

All but the injector cleaner, im in the process of checking fuel pump pressure to see if around @ 50 PSI, i changed the quick disconnects and they are ported correctly, and the fuel filter, did all the checks you mentioned,wondering if a piece of rubber dislodged at that time?? ill pull the fuel rail next and check the injectors, some times when it sets out of 15 start ups it fowls the plugs, i want to pull everything apart its a 19 year old bike, i also removed and capped the fuel canister and checke for air leaks at that time.
process of elimination at this point...
