That looks very interesting Doctorot. I would like to see the finished article when its done.19th May 2020 at 8:42 am #25593
I have fitted an oil cooler. Mine runs off a modified oil pump that is piggy backed off the oil pump and the oil lines come out of the engine at the front of the sump and upto the cooler.16th June 2020 at 6:03 pm #25628
Hi Chris. I’m interested in your oil pump setup, are you bypassing the filter? Can you elaborate or show some photos? The last engine I built I had a miss-shift and violent over rev resulting in oil pump cavitation and ended up with rod knock shortly after. I have been considering running a stand-alone electric oil pump to avoid this in the future.

I used an old oil pump internals to make a pump to run piggy back off the main pump.

interesting, so its a secondary pump system just for the cooler. Very tidy bike as well. I see you have it badged as a 865, what pistons are you running? other engine mods? I’m in the middle of a big bore build myself. Nice work. thanks for sharing.

Superb work,how did you know the extra plug would cure the pinking? And what was the compression?20th June 2020 at 8:46 pm #25647
In 2006 we met the german 750 twin club at Deulin in Belgium. Martin Schetter had an 865 he had done and i had a spare engine , so i made it into an 865 , keeping my original engine as it was. when i had the 865 running there was severe pinking and when i mentioned it to Martin he told me of the second plug. So i fitted a second plug and it cured the pinking. the 865 has been in the bike since 2007 and runs perfectly well on same carbs and ign. timing. My starter motor copes with the extra compression, thankfully, bescause i’d hate to have to kick start it. Power wise the only thing i’ve noticed is the extra torque. I had the pistons made in germany where Martin had his made, forgot the co. name.
