ejute63 Posted June 24, 2008 Share Posted June 24, 2008 I have a 1980 model DT175 enduro. It has been hard to start? I have fitted a new plug etc but It's still hard to start. I can bump start it OK and once started seems to run OK.It seems to start OK when warm/hot but is difficult when cold. I have checked that the plug is sparking by removing it, earthing it out on the motor and kicking it over,it sparks but I'm not sure if it's what you would call a strong spark? I'm wondering if about the CDI, coils, black box etc are not what they should be?? Any help would be apprecciated. Thanks Mark Link to comment Share on other sites More sharing options...
billa65t Posted June 24, 2008 Share Posted June 24, 2008 Hi Mark from the sound of things it sounds more like you have poor compression either due to worn or damaged rings! when it's cold and you try and start it you are not turning the mtor over fast enough for it to draw in fuel due to the worn or damaged rings but when you bump start it you're turning the motor over that much quicker. When its warm everything has expanded enough to give you decent compression therefore it starts? if you have access to a compression tester see what reading you get and check this with your dealer then you will have a better idea what is wrong Hope this of use to you Regards Bill Link to comment Share on other sites More sharing options...
