Noobercycle Posted August 25, 2006 Share Posted August 25, 2006 Hi all, I'm trying to get my 1978 DT175 started. I finally got the tank cleaned out and filled it with gas and now I'm trying to start the sucker with the kickstarter. I pulled the choke and verified the fuel line was open and not clogged. I kicked the hell out of it to no avail. It actually did make a brief putter (.5 seconds) like it was starting up but then quickly died. The bike has been sitting for a year is what the previous owner told me. The fuel lines aren't clogged, the clutch appears to be operating smoothly, which makes me think it may be that my spark plug isn't firing. I checked the plug and the connection to it and they both appear clean, so now I'm stumped. I don't have an ignition coil because the previous owner took it off along with the airbox, taillight, turn signals, and relays so he could use the bike soley for offroad use...so he has presumably been riding it without the ignition coil. I know the CDI is supposed to transform the voltage to very high so the current can jump the spark plug gap but where does that electricity come from? If I only have the CDI is it recieving electricity from the magneto as I turn the engine over when I kickstart even if there is no iginition coil or battery to feed the ignition coil? Is that how the first spark is generated that fires the piston upon startup? I'm trying to figure out what I need to buy or if I should just take the bike in to a shop (only problem with this is that the shops are too far away and I can't get the bike there because it won't start...so frustrating). I hope somebody can help...school's four days away and I need my ride to work! Link to comment Share on other sites More sharing options...
dtr_125 Posted September 28, 2006 Share Posted September 28, 2006 hi im not very educated in bike stuff but i had a scooter that had the same problem not starting i had checked and even replaced stuff such as spark plugs ect, it turned out that it had no compression (sumert to do with piston rings ect were totally kackered ,the shop had it nearly 2 months tryin to solve the problem) but was quite costly to repair. this may and hopefully not the case money wise but hope it helps Link to comment Share on other sites More sharing options...
Stikkerman Posted October 1, 2006 Share Posted October 1, 2006 If you've not got a coil, where does the H.T. lead go to ? Thats the cable that has a cap on it that fits on top of the spark plug. Martin. Link to comment Share on other sites More sharing options...
