Re: 1997 Yamaha SWS II 250 has no fire!!! Please Help!!!
the seal prevents trash on the tank bottom from entering the pump, the vent,if not properly lined up will allow overfilling.
if you will notice the filter does not have a screen for the first 1 inch or so, thats to give a margin for trash and water.
my advice would be to go ahead and rig this machine properly,catch up on any maint issues like pumps,VST filters, O2 sensor output tests and maybe even flushing the injector filters.
if you keep messing about you will post about a knocking or loss of compression.
if the seal is not retrived its possible to mash it down the tank to pump hose and shut off oil to the pump.
I see 2 or 3 each year that inccorect maint was worse than no maint.
the OX66 225 was a very solid motor, it wont tolerate inccorect maint or running conditions.
it is more than willing to pop a piston if something is not right with the fuel or ign system.
the oiling system is almost bullet proof if the correct procedures are followed.
