Hello, I have a problem and decided to ask for some help. I have a 1988 Electra Glide Classic. Yesterday I started it, let it warm up, and put it in 1st. It was normal. I drove down the road, and a couple blocks, it started jerking. I tried it in 1st, 2nd, and 3rd, and all the same. also when shifting and letting out the clutch, it grinds. I parked it and walked and got my truck and brought it home. Before tearing into it, I want to see if anyone can direct me in the right direction, as far as, what it may be. Thank you

 

the belt drive sprocket was a bit loose and it was rocking back and forth until the teeth were all gone and it came to a stop

 

In my case it was the transmission mainshaft bearing.

 

You need to be able to tell the difference between a missing cylinder and a trans problem.
If you have no clue. get REAL help or you might spend a lot of money on nothing that will fix it.
You might just need a spark plug, coil, wire etc

 

It definitely is a trans problem. totally different symptoms than a spark plug miss. It is the main shaft. I went into it today. I have enough Harley experience, (45 yrs) to do my own work. Thanks for your advice.

 

Sorry about your problem, but glad you got it figured out.

 

What happened to the transmission mainshaft?
