bookem Posted March 6, 2011 Share Posted March 6, 2011 Got a question about the oil pump on a '78 DT175. If the oil tank were located lower than the pump will it suck the oil up or is it strickly a push pump? I'm building a street trike andwish to install an oil tank farther back and lower under the solo seat I've built. the tank top would be about even with the inlet to the pump as far as height goes so it would need to pump up a 6-8 inch incline max. Thanks for your time guys My link Link to comment Share on other sites More sharing options...
Moderator DirtyDT Posted March 6, 2011 Moderator Share Posted March 6, 2011 I can't answer the question but I do not think I have ever seen a custom 2 stroke trike. Good luck with it! Link to comment Share on other sites More sharing options...

Thanks for your time guys My link I wouldn't think that 2 stroke pump would lift oil over that distance. It only shifts a tiny amount of oil so drawing oil down a pipe that length is at best a hope. Considering how important the 2 stroke oil is, if the tank will go nowhere else then i'd be blanking the pump off and using premix. Is that engine not a little weedy for dragging a trike chassis around? Link to comment Share on other sites More sharing options...

I'm building this as a slightly beef moped idea. It'll get him around on the back roads but wont be a highway machine.

bookem Posted March 6, 2011 Author Share Posted March 6, 2011 I think I'll run premix and the oil pump as well. If the level goes down in the oil tank then I'll stop with the premix. Even with synthetic it should smoke like an early 70's farm beater lol Link to comment Share on other sites More sharing options...
Moderator DirtyDT Posted March 6, 2011 Moderator Share Posted March 6, 2011 If it needs gravity as well as the pump, have you considered using an enduro type fork mounted plastic tank for the 2 stroke? Link to comment Share on other sites More sharing options...
