2005 r1!
came home last week from my ride....after 7 days of non riding i went to turn it on everything seemed normal...took it out of the garage and after 1min it suddenly died! took me forever to turn it on and white smoke came out from the exhaust then everything was normal! took it for a ride for 10mins and started pushing it hard at 10 000rpm the bike seemed to have lost 50% of its power...the maintencance people told me its the fuel pump! so i changed it and now the bike take lik 10 times to turn on and when it does the motor sounds like its struggling to stay on and when i give gaz its turning off! please help!

pull plugs sounds like not all cylinders fireing. Could also be tb's need to be sync or coil packs. Check that stuff first.

DOn't think i'd push the bike hard if it's belching white smoke.

Whats the oil in the oil glass look like?

maybe the new pump is not good ! i am lost! damn it!
