hey all,
the 1995 stock battery and starter would not turn the 107" fast enough to fire her off. So, i bought a new battery, still no go. so, i have modified the 90 ultra spyke starter to work with the 95 ultra setup. if this does start the 107" i guess i have something in the primary too tight or something is dragging, maybe the stator rotor or something. Any ideas on what to check ?
pics have been added to the rebuild album if anyone is interested.

Yea, every time I ride, it seems to run better. It pulls low pretty good, but really comes on strong after getting up in the rpm's.
I may go next year to a six speed and swap out to a right side drive too. Have been checking out custom swingarm to fit a 280 or 300 and make this thing a bit more radical.
But that will all depend on if I score a Street Glide for riding 2 up with the old lady. As long as I get one of those, then she'll leave me alone for a while.

"I am getting 38 around town and 44 on the road. That is riding 2 up."
I have about 500 miles on the 113 in my 87 heritage and can't get 100 miles of mixed riding before I hit reserve (3.9 gallons). I'm not beating on it during break in, but do get up around 75 on the highway commute.
Engine runs great starts fine and actually seemed to run a little lean "out of the box" I adjusted the idle mixture screw about 3/4 turn from stop and the cough went away.
I am running an 80 db Santee muffler which has the large stepped header but is pretty quiet. I am willing to sacrifice a little bit of performance to keep the muffler, but not an extra hour of saddle time per tank.
I am unfamiliar with Mikuni tuning, but got pretty good on my old S&S.
Would appreciate any thoughts. Would the restrictive muffler cause such poor mpg? Is 3/4 turn on the idle mixture normal?
Thanks in advance.

Thanks John,
The 107" Ultima stator area is different than the stock 1995 Ultraclassic. anyway, to make a long story short, I f*&^ed up and tightened the rotor down on the stator. well you all know what happened. it was dragging on the stator and rubbed the wireing of the stator and shorted it out. Moral of the story---check the clearance on the rotor to stator. just another setback and MORE money!!

Yep, that will make it hard to start. When we did the 120" in our '95 FLHT, we used the 38 amp setup and it bolted right in. Oh and on the '95 EFI bikes the coil wire was either yellow/blue or blue/orange, the third wire yellow/green went to the injectors. Check the first two and find out whichone(or both) is switched via the handlebar switch as you need this feature for safety. Oh and if you haven't figured it out, it looks like without changing a lot of stuff you need to keep the ECM for the cruise to work.

Thanks Baggerparts and Miacycles for your suggestions.
I ordered another 38 amp stator yesterday. I hope i can make it work. as per John it should. I had no problem with the clearance in the 90 model with the 32 amp stator.
John,
thanks for the tip about the cruise. But, i have already stripped the ECM and the wire-harness from the bike. I had planned to put the cruise on my 99 roadglide if it were compatible. all it needs according to HD dealer is the cruise mod and the cable and a Mikuni adapter for the 45mm. However, thats another day.
