Hello, I have read through a whole evening's worth of posts about HPDI filter maintenance as I've been having the high RPM bog down. The comments about holed pistons scared the life out of me and I don't want to run it till I change the medium pressure filter and clean the VST (and replace the lift pumps). I will order a shop manual but in the meantime I want to see if I can get an idea of how hard it is to get that VST and its filter out for cleaning. The posts I read were old and contain stale links. Nothing on YouTube for this motor. Does anyone have a pointer to anything recent that instruct on how to do this VST job on a 2001 200HP Yamaha HPDI? Thanks.
Now I have to hold my breath and hope I didn't do too much damage to my pistons. I think I first noticed the problem about 7 running hours ago.
