well i wondering about those like me who have carburetor maybe our charging systems could handle the oil pump put in series with the oil cooler bolted up?

have you looked in to 3d printing? 3d printers print plastic parts in 3 dimension, using high grade plastics. you could make the shaft, round with 2 flat spots and have a gear printed up to fit.

I have a thread here about planning, making, and fitting an oil cooler with a pump. It does work and my 139QMB with a stock(ish) charging system can handle the load from the pump, run a 35w or 55w headlight, and still charge the battery.

I also use my 3d printer in that thread quite a bit. I don't think the plastics that are commonly used, PLA and ABS, would be able to hold up to the speed and heat that the gears on the oil pump gears are subjected to. Also, if the gears themselves are submerged in oil, I'm not sure if either plastic will be tolerant of the hot oil.

There are other materials that 3d printers can use like bronzefill which is PLA with 90% bronze dust added. There's also some that have carbon fiber in them.

This is a very big part that is lacking on these machines,,,rich and I were discussing this very thing before,,, well you know,,, oiling is marginal at best ,, more flow is needed given the fact that they don't carry much oil anyways ,,, and even a smaller cooler will expand capacity and create more cooling surface area,,, it would be a win

HEY THANKS! All of this interests me. i do want an HID or LED light that is brighter and i would like an oil cooler. This helps out very much! gonna book mark your link. we think alike. i'm close to getting a 3d printer. if the Davinci 1.0 goes on sale again i'll pick one up and get the preterier firmware. not the best but, realy DECENT for the money once the non factory firmware is installed.

I may try to pick up where this left off. a friend is machinist i may ask how plausible it is to make a crank and oil pump gear. in theory to a limit w can just make the gearing taller so the pump spins faster.

Well I don't have much time these days. I didn't finish the test mount. I just put the pump in. So far there has been no oil issues. the modified gear has held up. I have a new plan using a belt driven pump. the plan is to be able to use an oil cooler and good filter. The belt will be driven off the crank on the flywheel side. Still in search of a suitable pump. Pump must be able to self prime, handle the heat of the oil and be small enough to mount in a suitable location. Also must be of reasonable cost.
