clean and regap the points
clean any rust from the flywheel magnets
clean rust from the armature pick ups
clean rust where the stator plate mounts to the engine case
clean the area where the condensor mounts
clean where the charging coils mount to the stator plate
check all wires for breaks or wear thru spots
test the charging coils for output
make sure all connections are clean and tight
check for resistance thru the ht coil
check the spark plug wire
check the spark plug boot
replace the spark plug
make sure the kill switck works and is not shorted to ground
make sure all tail light bulbs are good
make sure tail light is properly grounded

if you have cdi, and the charging coils in the magneto show output, replace the cdi.

IT will not fire. I am getting output from the charging iggy coil.   I hooked up my multimeter to the red and white wires coming from the magneto. I set the meter to VOLTS and and spun the pedals simulating starting. got 6.9, 6.7 and 7.0. So it shows output, but how much output should there be?
I cleaned the guts as well as could be. I sanded and polished the coil armatures or whatever they are that the magnet passes over. I cleaned and sanded the flywheel as well. I checked the ignition coil and it shows continuity. But when I check the plug or iggy coil for out put there is none. I grabbed the wire and pedaled like crazy and nothing.
I replaced the iggy coil with a used one once when it had stopped before. it worked perfectly after wards. the used iggy coil is still in place. it seems to test alright. I got a new motor ordered but if I don't need it i don't wanna buy it. I went completely through the olde motor. repacked bearings and cleaned everything I could. It went back together and I installed it no problems except for no spark. I even set a mirror in front of the headlight to test the lighting coil and pedaled like crazy, nothing from the headlamp. . This is the fourth time I have put this motor back in. This is the second motor. and I am on my last nerve. my fangers have been greasy for three weeks.   Hellllp!
thanks for the help!

HI DON P thanks for your help.
I got a five year old TFR with eleven hundred miles on it. I bought it from a guy for fifty bucks it was dusty and wrecked and looked awful.   and I took it home and fixed it . It cranked up and ran very well till the IGGY coil went out once, I replaced it with a used one and it ran like a champ. Goode compression and lots of power Cranked up on the first kick everytime. and now the clankity clank syndrome. After rebuild, engine seems quiet and has goode compression.
I reringed it and cleaned and sanded and double cleaned everything I could finde. will the CDI and IGGY coil COMBO work for my TFR? right now it's two separate units. thanks again DON P
thanks for the help!

i would check the tail light bulbs, and make sure the kill switch is working correctly, and install a brand new spark plug.
