103" Stage II Hard Starting
This is the normal sequence, unless I've been doing it all wrong
I spent 3.5 hours at Laidlaws in LA only to find out that they can't dyno tune it with the stock exhaust system in place. Seems the cat is in the way so they can't get the sniffer all the way up it's a$$. Turns out this is the first '09 with stock exhaust that they've try to do. The tech was very gracious and suggested that anything he did would be pure guess work and that it wasn't worth the money. I took his suggestion and left. He also suggested that there is a more experienced guy at another dealership and maybe I should check with him and see if he has any ideas relating to the hard starting when hot. Other than that he said I could always have compression releases installed if the problem persisted. So, now what? Nothing I guess. Geez...Marc

I'm putting mine on the dyno Friday. So I'll let you know what happens.
2. These guys that say "I have x comprssion and starts just fine" are yanking your chain. Your SE255 cam has an early intake close at 25 degrees and develops more CCP than the Head Quarter builds and many others. Your CCP is around 205. The others are around 195. Big difference for the stock starter. Later closing intake cams will effectively reduce the cranking compression.
3. The stage II need compression releases for starter longevity based on what I have seen.
4. Some tuners can use the stock location O2 sensors to tune.
5. Some of the starting timing suggestions should help but I have not played with them myself.
Hope this helps.

Did you have them install the headers that came with the SE STG2 Kit? Those have the cat in them. I heard if you use the factory headers (no cat in them) then it will work.
The big question is if retarding the timing and/or adjusting the mixture would actually cure the hard starting problem or if it in fact needs compression releases for the long term. The cost actually works out about the same. The labor to r&r heads runs about $500 plus the labor to drill the heads estimated at $100 plus the parts which should run about $200 totaling about $800. The SEST with discount runs about $400 plus another $300 or so to have it tuned totaling about $700 not including an aftermarket exhaust in order to get rid of the cat.
The argument is that if the tuning actually fixed the starting problem I would get the side benefit of it maybe running better while installing the compression releases will for sure fix the starting problem with no other advantages. Interestingly, yesterday I rode home on the freeway in miserable traffic for about an hour and half. When I got home the motor was pretty hot which is when it normally has its problem. I waited a couple of minutes and restarted it and it cranked right over. I tried it twice with the same result. What does that mean?? I'm contemplating just waiting a bit and see how it goes and if the problem continues then probably install compression releases. At least that's the plan so far today..
I hate to say this but now I wish I had paid the extra labor and had the dealer install the kit. If I had I'd just park the thing in front of their door and let them work it out. Having had an independent do it kind of precludes any help from the dealer or HD for that matter. Lesson learned.

I know of such a tuner in Texas, and it was worth the ride and motel rooms to have him tune my 103 inch 09 with stock pipes..
Purrs like a kitten.
If it ever does cost me a starter, I am dam sure replacing with the heavy duty starter and also pay the dealer to get the compression releases installed. I hate a bike that won't start. But I love my big bore 103". The only way in time I am going is bigger bore. No substitute for cubic inches in a slow speed tractor.
