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

What are the options for replacement / upgrade / spring upgrade on a 1979 DT175 monoshock, would a shock from a similar vintage IT fit ? Thanks Mark

I have a 79' model DT175 which I'm getting ready for registration. The oil light (2 stroke tank under side cover)is on all the time. I have pulled out the switch and checked the operation of the contacts which seem OK. The switch has 3 wires going to it ( I could not work out why it needed 3 wires?) and on closer inspection I found that there is a diode inside a resin type of plug in the top of the switches rubber top. I checked the diode and it seems OK. ( I'm an Electrician) When I disconnect the diode the switch works OK. I would like to know what the diodes purpose in life is?? Why would you need a diode across what should be a simple switch?? Thanks Mark
