Posted August 16, 20177 yr Hey everyone, I finally found a forum for the Chappy! Â I have two 1975 Chappys. One was my first motorcycle that my pop got me when I was 10. (the yellow one) Â I am restoring it to give to him for his birthday this year without him knowing. The engine is good but the other components are not so good.. (the red one) I purchased another 1975 LB80 locally and it has a bad engine, but good other components. Â So I say my yellow one has a good engine, as in it started and ran a year ago around December. I have it now in my garage and it is not getting any spark.. Where do I start?
August 16, 20177 yr Hi First off set the ignition timing to 1.8mm btdc and dress the points ... there after just check the ht coil for the correct resistances ( they elude me for the minute) and the resistance of the plug capÂ
August 16, 20177 yr Author I am totally new to this, what does "BTDC" I assume its something to do with top dead center? I have new points for it, I don't know where they are or how to install them. Â I took out the ignition coil and got a new one but forgot to mark what wire feeds the coil..
August 17, 20177 yr before top dead centre (center) The coil should have an orange or black wire attached The points are located in the magneto ... l/h engine side cover but you will need an extractor to remove the mag in the UK UK you will need a P134 extractor see https://picclick.co.uk/Flywheel-puller-extractor-Yamaha-FS1-FS1E-310667328436.html
August 17, 20177 yr Author alright, ill get one of those, replace the points and try to find the wire that connects to the coil.
