How do you know the bike does not have a tuner on it already? Have you pulled the seat to take a look?

There is also a good chance that the HD Mothership has no Idea what was done to the bike. I tried the same thing with my 05 Fatboy and they had no record of it.

If you cannot find a record of what was done and specific cams and compression, Fuel Moto will have a hard time with supplying the correct map.

And your biggest issue with low end torque is the true dual exhaust setup on that bike

 

this is an exact cut and paste quote from the same post you're referencing

"once I know what I have I guess I could atleast order the tuner with a map from FM"

as I said once I know exactly what I have then I can at least get the tuner and a map and ride with that until I decide if I'm going to upgrade Parts on the bike or not and decide to go with either the auto tune or Target tune add-ons or even have an actual Dyno tune done.

 

you have me there I have no clue the Blake may have a tuner on it I have had the seat off because I had to replace the battery but I wasn't looking for anything. I just wanted to get the battery in and get the bike off the trailer and put away since it was like 10 degrees outside. I never thought to look or even considered that the tuner would be left on the bike.

I'm hoping to get lucky with the dealership since the previous owner told me that as far as he knows the bike spent its whole life a couple of towns over. That would have put him right in Horsepower Harley-Davidson of Williamsport pa's backyard and that is one of the two most popular Harley shops in the area

if I strike out there I'll probably end up doing some exploratory surgery or letting my local Indy dig into it a little bit to at least give me an idea of what I'm dealing with so I can figure out where to go from there. The downside to that is I probably wouldn't want to dig into it until next winter and I have limited free time but at least the bike does seem to run perfectly fine so it's not like I'm on a deadline. I just can't stand not knowing and I didn't really think about it when buying the bike. When he said it had a 103 I just assumed that somebody slapped a quick Big Bore Kit on it and called it a day not realizing it wasn't that simple with a tc88 like it is some of the newer Motors.

I'm not really looking to turn it into a monster either but if there is just something simple like one part or a tune that is really holding it back and could live in it up I would gladly do that. I wouldn't mind getting a tuner and either swapping cams or pipes but I'd really rather not have to do both just do to cost. I also wouldn't mind changing the gearing at the pulleys to trade in some of that top speed that I never really use. Some people may want a 130 mile per hour Harley but for me I cant honestly say I enjoy being much over a hundred on a Harley

 

The manual is the next thing I need to tackle. I've heard quite a few times to get the Harley manual over any of the aftermarket manuals over years but I've never actually seen a Harley service manual I'm going to see if a friend has one I can check out. Everything else I've ever owned I've always been told to make sure I got a Haynes or Clymer manual for it and those always served me pretty well over the years but if the Harley manual is actually worth three times the price I'll gladly pick one up.

 

It's looking like some exploratory surgery is going to be the only option. I spoke to the dealership where the bike was originally purchased this morning and they did have some stuff in the system but it was all just basic service stuff like changing light bulbs and oil. Hopefully I can at least get a compression test done today or tomorrow and see if that helps at all

 

If you intend to work on, modify, etc. your bike; the HD service manual is definitely the one to get. The others will just frustrate you.

 

How far are you from Nazareth? Dave @ JDs can access your ECM to see what map is in there, & if a tuner is installed, and can perform a baseline dyno to see where you're at performance/efficiency wise. Decisions can then be made.

 

also found 2 sets of numbers on the bottom half

0600522542
*jdb5042170*
shouldn't there be some writing on the cylinders or heads besides just the little plate that says cnc-ported?

 

sorry I missed your post when I dropped in to add about finding the numbers this morning. I am two and a half hours from Nazareth I'm close to State College Pennsylvania. I'm not sure what his turnaround time is but that would be the deciding factor with being that far away only because I work 6 14-hour nights a week so that kind of puts a damper on things like that. Now if I could find a way to strap it to the milk truck that would be another story since I drive by that area almost nightly for work. If that is something I could get done in an afternoon that would be pretty sweet.

 

He does work by appointment, so I'm sure something could be worked out- even if it's a trailer hitch on the milk truck
I'd call him @610-297-0321
