SE compensator will solve most issues IMO MOTO CO should include this in upgrade package.

 

What values did you use, and is it based on time or temperature? Have you are anyone else tried retarding the timing at 500rpm to ease cranking pressure?

 

I have a 103 with 55K on it, stock starter & no problems, it depends on the cam you're using as that has a big effect on cranking pressure. That being said I'm running a Crane 290, very similar to SE 251, with 240 248 duration & still no problems, most of the problem can be solved in your tune, just need to keep the advance backed off at low rpms, such as when cranking it over.

 

Compression releases... My tunner recomended using them even with a good tune... The releases may cost $80.00 but you still have to have the heads tapped for them

 

2007 road king 103 kit se pistons and heads 255 cams se race tuner 10,000 miles since upgrade no acr's and no starter problems just lucky i guess

 

As I have posted on many threads before, my starting issues continued even after a new starter was installed on the stock motor. It wasn't until I installed the SE compensator that the banging and kickback was illiminated. I knew I was going to do motor work eventually, so I wanted the SE comp before I did my 103" build. I also installed MCR's when I did the build. No issues now. It seems some have problems and some don't.

 

Also try heavy duty battery cables from Sumax, Howards Horns, and some others, really makes a difference.

 

S.E. Compensator, that'll fix your problem. Don't waste the money on the other things, just try the compensator first and see if it suits your needs. If not, then the compression releases would be my next purchase, but I feel sure you'll find the SE Compensator will fill the bill.

 

Thanks everyone for you r input.
