Hi Everyone,

I am new to this post and hope you can help my 14 yo stepson. He just bought for $100.00 a 1979 80cc Enduro. I know nothing about dirt bikes or motorcycles but I am pretty handy. The bike is in reasonable shape for 100 but no back brake and if it kick over is does not stay running. I ask him what gas/oil mixture he used and he said 53:1, No one told him that he just used what his buddy uses for his new bike. What is the proper mixture and is there a place I can get a service maual for this. I was going to take the caeb off and clean it out but thought I should get some advice first.

Thanks for any help

Regards,

Ron

Hi the title says 1970, and your profile says 1979??

Does it not have an autolube pump?

My DT175MX is 1979 and that has an autolube pump, You need to find out where yours is or confirm that it has been removed, Much better than mixing in the tank

If the autolube system has been removed you should mix at 32 to 1 ratio.

if you use a fully synthetic racing oil then go no less than 50 to 1 on the pre mix
