Title: Watercooled XR75 cylinder
Post by: Mick22 on May 11, 2008, 11:57:29 am
I just sold some bits to a guy on ebay and when he picked them up he mentioned he had bought a watercooled cylinder for a XR75K0 but couldn't find a piston for it, i've got a box of old Honda NOS pistons so he brought round and we sorted out a piston.

Has anyone seen one of these before??  The only markings it had was ME stamped on it.
It was a full kit with radiator pipes and frame mounts. The reason I'm asking is it didn't have a water pump and we are trying to sort out if it just works on convection or if the water pimp is missing ????

Some kits around for the 5 speed engines but never heard of or seen 4 speeds kits. However thats not to say they dont exist. Very possible some limited kits may of been produced.

the ME on it suggests it may be a Mugen kit possibly.

 i never knew they existed at all for either the 4 speed or 5 speed.

Sure it was not oil cooler kit that use to be made by Lockhart for the XR75, they bolt to the front down tube of frame.

I'd say like the Shinobi heads it would be a no pump setup ;)

It looks like its for water, it has a pressure, I think it must just work on convection??
