| Post subject: | Barry B's oil pump question on KTOG |
Barry B's original topic on KTOG, "I am getting ready to remove my oil injection pump, lines and check valves to be redone I thought I read somewhere where Kawasaki used a different oil injection pump in the H2R is there a benefit to using a different oil injection in a 72 H2 to cut down on over oiling now that we have much better oil available now let me know your thoughts." The H2R oil pumps were the same as the early style street bike H2 3 line pumps, with a small variation. As we all know, the street bike pumps varied the output by two methods, differing rpms of the rotary sleeve inside them, and by shortening/lengthening the stroke of the sleeve as throttle position was increased, to vary output. The H2R's had a different top controller, and did not use a cable to vary the stroke length, only variation was in rpms of the rotary sleeve. The actual cable holder was replaced with a set position part, screwed down to one of the two posts on the top of the pump, eliminating the stroke change ability. The crankshafts were oiled the same as the street bikes were, down a stock line bolt with meter at the bottom, to the left main for each cylinder, then to the oil receivers on the left side of all left hand crank wheels, down to the rods, same as street bike cranks, right down to the same oil receivers. Stock street bike oil lines and check valves were also used on the H2R's. The cylinders had no oiling output restrictions in the intake port floors, and, the remaining engine oil was by pre-mix, 30:1 fuel to oil mix ratio, Castrol R, 30 weight viscosity. Variations have been used on a few different setups, including one year in Australia by Kawasaki legend Hurley Wilvert. For the Castrol 6 hour endurance race, HTW and team ran a stock class early H2, which rules stated MUST use oil injection, and NO pre-mix. So, Hurley fitted an S1 oil pump, with H2 cable wheel, and ran the entire race with that setup, eliminating added stop time to raise the seat and fill the oil tank. The bike ran the entire distance, 6 full hours on one tank of oil, no lost time to refill the tank, without oiling problems/issues. Very clever. |

ran my H2 with a KH250 oil pump for a lot of yrs with on problems, but i found it very close to the edge, I found that if the filter in the bottom of the oil tank gets slightly blocked or you get an air leak then it will nip up, now run a 400 pump to give a bit more margin for error Gary T |

i would have thought that most of the pumps were very close in output due to bore and size of oil pipes and the cam that controlled the volume was the main factor |

There are output charts on Dale site....... |

The pumps are a positive displacement type, so restricting the lines or using smaller lines doesn't change the flow, just the pressure the pump has to work against. The flow is so low that the lines can be very small without causing undue pressure. Dave, that's actually a different Barry, but of course that doesn't change the facts of the pump.

I just cut and pasted the topic from there to here, and that is the name on it over there at KTOG. Only did it for info for everyone. On early H1's, we used to literally break the cable holder off the wheel, and cut a slot a lot further down the wheel, at the cable guide, and affix the cable there, cutting pump output significant;y, never had issues with doing it that way, either. As I said, just FYI from 4 plus decades ago, still applicable today. |

It's a guy on Brad's board "Barry's H2". Here's the thread: http://kawasakitriples.myfastforum.org/about7607.html&highlight=&sid=4fee334b1f576ec05ebd0c72b6d2a192 |
