Posted July 11, 201113 yr Hi everyone,I was out riding my yamaha DT 175 today and every thing was fine until the ride back when i had to stop at a intersection when i went to take off again my bike started runing real rough like it didn't want to tack out and it was smoking real bad in first gear and part of second gear then it would go back to runing smooth again and not smoking anymore. and ran fine until i would stop and it would do the rough running and smoking again until i got past second gear then it would be fine again. any ideas what might be going on thanks.

Sounds like the oil mixture is to hi on idle, not sure if the 175 is self mixing or not but if it is check the oil pump make sure it aint stuck wide open.

July 13, 201113 yr Author yea it has a oil injector ,i'll take a look and see if the oil injector is hung up thanks,is there any thing else though just in case that could also cause the problem yea i checked and the oil injector was not closing all the way so i put some oil to the cables and it work fine for a little while but went back to sticking ,i was wondering if i byepass the oil injector and just added oil to my gas what is the proper oil to gas ratio?
July 13, 201113 yr yes all you do is disconnect the oil feeder to the carb and block that port off on the carb. then run premix in the tank.... bit of a bugger sometimes.... could probably even go to the extent of removing the plastic worm gear too if oyu wanted.... cant remember the ratio of pre mix i DO KNOW however that mower and chainsaw oil causes them to nip up all the time .... dont ask lol
