2002 V-Star 650 no fire rear plug
I brought a V-Star 650 last year, run great the first week or so then became hard to start, would run great after fooling around with choke and throttle to get it running,
Then it started to run on the front cylinder only, kick in on the rear once in a while, plus backfiring,
The trouble shooting started with changing the plugs, then the pickup test failed, was reading like 500 OHMS, changed the pickup, no better, next the coil and spark plug leads test Ok, did the negative ground test and got fire on rear cylinder, So from what I read here the CDI is defective, priced one at the Yamaha dealer at $680.00 plus tax, started looking on e-bay, found a used one for $150.00, order and put it on figuring my problems are over, no dice, runs a bit better with the e-bay CDI seems to run on rear without backfire and exhaust get hot, still no power or throttle response. no power. I have read most of the post here about this rear cylinder weak to no fire issue but no one post what has been done to fix it.
I have ordered a new Dyna 3000 CDI and a used set of coils hopefully it is the CDI because all the test point to this, any and all comments are welcome, sorry for the long post but I am pulling what little hair I have left out trying to fix this problem.
