Had a the PTO side cylinder melt down on my 97 ZRT600 and suspect that the issue to be the oil pump, I replaced all the 1/8 hose from the pump to the carbs verified that all the brass nipples on the carb boot are clear and I've remove the pump just for visual inspection. I reinstallled and reconnected all the lines / adjusted the cable...I also blew into the resvior vent line to get things pimed a bit... The hose runnig from the pump to the PTO carb has not filled completely the other two lines however appear to have oil in them. Was wondering if this normal since the PTO hose length is the longest or does the machine need to be running first to pull vaccuum on these lines. Just to be safe I plan to use a bit of mixed gas when I start the machine and watch to see if the line fills. Need to know how to bench test oil pump or a more effective means to prime it...I don't want another meltdown next year.
