100 trail oil injection
« on: February 27, 2011, 02:04:56 AM »
When i got this bike all the oil injection lines were broken or missing. I have tried to find fittings that would fit so i could get it to work but had no luck. However need be i can make something work, but i believe it would be easier to just cap of the hoses and run mixed fuel, though i do not know if on these bikes you can do that, plus if it is, do all i need to do is to cap the inlet and outlet lines on the pump and the inlet to the engine. help would be appreciated thanks

On the BS90 / BS100 engines, the oil pump simply sprays the oil into the inlet tract behind the carb, with no direct feed to bearings or cyclinder. It relies on crankcase turbulence to mix and distribute the oil - just like on a mixed fuel "petroil" system. Make sure you do cap off the oil feed holes - otherwise you'll suck air in and weaken the mixture. To be safe, it would probably be a good idea to remove the oil pump and its drive shaft altogether and fit a blanking plate over the hole in teh transmission cover. This will obviously entail some dismantling, but I would be concerned about the oil pump innards still spinning around and not being fed with oil from the tank.

If you do go for a pre-mix fuel, stick to a 20:1 ratio, the same as used on the early BS90s and watch the blue smoke trail appear!

Hope that helps.
