offroader >yours sounds to me as the timing is retarded and firing before full compression that will cause all your symtons running hot missing caughing ets do a static time on it hope this helps

 

try spraying carb cleaner on the manifold while running to see if it may have a leak that will cause a bad miss

 

Always go with the cheap stuff first.

Check and clean both battery cables at the battery and also the ground cable to the frame.

Be sure the battery has a good charge.

The carb on my '98 Evo gave me real headache this past spring.
Remove, disassemble and thoroughly clean the carb and blow it out several times with compressed air and be sure that the float level is adjusted correctly.

With the carb off replacing the intake seals isn't much of a job and as old as they are they should be replaced and they're not very expensive.

Make sure you have fresh fuel.

I've had two bad ECM's in the past and each one acted differently but neither seemed to have only one cylinder firing but anything is possible.

Ever figure this one out? Got something similar going here...

Hi guys, Rob here, newbie to the forum. Excellent site and excellent answers to the queries. I've a similar problem that seems to clear after running for a while. So, thanks for the input guys, lots to mull over there and learnt a lot too.
Riding a '95 Fatboy when I'm home but out in Middle East for a lot of the year so she doesn't get used as much as should.
