DT175 1978 Posted September 27, 2012 Share Posted September 27, 2012 Hi. 1) What fuel should I use in my 1978 DT175? The easy choises would be 87,89, or 91 octane. Which is advised? 2) I need to order an air cleaner element for the same bike. I can find K&N's that'll fit, or a NOS / original. 3) I figure if I go K&N I'll use their filter oil & cleaner products, but if I get an original - do I just oil it with 30w oil and put a little axle grease on the sealing edge, or is there some better way to do it these days? (use K&N cleaner and filter oil on an original type?) I appreciate any and all input. Thansk. Matt Link to comment Share on other sites More sharing options...
Moderator Airhead Posted September 27, 2012 Moderator Share Posted September 27, 2012 I would go for an OEM one they're very good. And coat it liberally with the thickest oil you have...then squeeze out the excess (as in dont wring) Link to comment Share on other sites More sharing options...
