Leakdown test results on my 09 570

I finally bought a leakdown tester and had to try it out. Had to pull the valve cover to get things lined up to lock it at TDC and make sure the ADC wasnt engaged. Bike has over 305 hours on it, all off road. I'm pleased with the results and see no reason it wont make 400 or 500 hours before it needs a top end.

2% or so at both 90 and 100 psi

Yes original fuel pump. The black made in china one that is supposed to fail, changed the fuel filter for the first time around 280 hours. Has had a Dirt Tricks tensioner since near new. Original spark plug was changed at 200 hours but didnt need it. I have changed the water pump seals, countershaft seal, clutch and stator cover gaskets.

Oil gets changed every 10 hours or so, sometimes 15, never used anything but Rotella. Oil filter every 4 changes. Air filter I do as needed, keep a spare ready to go with Bel Ray or Maxima filter oil. Never Notoil.

I try to be pro active with maintenance and take care of things before it becomes a problem, not just the engine but chassis also. Forks, shock, bearings, etc. all get serviced regularly as well.

Its been a great bike!
