1975 250 Elsinore bought with no oil tank. Can't seem to get an EXPERT answer as to whether or not I can just pre mix. Bike runs well but haven't put any miles on yet til I know what I'm doing. SOMEONE THAT"S DONE THIS PLEASE ADVISE ME!!! Thanks to all for help, Barry B. |

Well I'm certainly no expert, but in '75 there were two 250's made. A CR250 and an MT250. The Cr was premix, the mt had oil injection. So, if your bike has no oil tank, and no oil injection setup, you have a cr. Just to check, I'd look at the neck where the vin # is. It will say which model it is. Also, look down on the motor at the number there. It will tell the truth too. The I'd/reference section on this site can clarify anybody this. |

Hi Mr. E. It is an MT250 totally, but someone has REMOVED the tank system. So my question is...is premixing good enough, no mechanical problems or anything of the like. BB |

The MT250 oil pump relies on oil from the injection tank for its internal lubrication, so if the bike's been ridden for a while with no oil tank the pump is almost certainly ruined. As long as the injection-port hole in the intake manifold has been sealed off, pre-mix will be fine. Ray |

Yes you will be fine,just mix your ratio to 32:1 and make sure the oil line inlet nipple on the intake manifold is closed off. |
