SOURCE: 83 yamaha tt600e no spark

The CDI unit on the 83 model (TT600) is located under the fuel tank and suffers from heat
exposure.The solution is to get specialist help to open up the sealed CDI unit and repair/
replace internal connections (which are readily available electronic components)
When you re-install it put some heat shielding material there to protect it and this
will be OK as repair will utilise stronger parts,I think.
Later models have the CDI unit moved to the head-stem area.

(this info from a Non-mechanic who remembers what was done to his TT in Australia, many years
ago)

Miss fire after up to temp and runfor short amount of time. I get a miss fire coming to a stop..drops to cylinders or 1. will not accelerate at all boggs with miss fire.


Check your tank vent. Ride the bike until it stalls, pull over and pop open the gas tank lid. If you hear a "ffffwwwwwah" of air being sucked in when you open the tank, your air vent is blocked. The bike runs great when you start out, but as fuel is taken out of the tank no air can get in to replace it and the tank develops a vacuum.

I have a 2001 yamaha v star 650 it will run for about 10 to 15 min then it will shut off then it takes anywhere from a hour to a hour and half then it will crank up and do the same problem


First of allyou need to determine if you are loosing spark or fuel.If you are loosing fuel,you might look at a plugged fuel screen inside thegas tank or of course a plugged fuel filter.If you are loosing spark,you are most likely looking at a bad CDI box.They are very good for that.
