seems everyone has missed my drift,
My suggestion was for a simple chart to be had that if you start with a standard carb'd Bonneville & one for EFI model too & if were to follow 1, 2, 3, 4, 5 & 6 mod improvements,
you'd will end up with a fun bike that produces 70 odd+ HP or whatever:ride:
simple & as I said close enough for most to have a fun performing bike ? :up:
don't really care if our bikes vary from bike to bike, it wouldn't be by much, given you start with a basic Bonneville, & follow these few simple instructions including the jet sizes etc,
I still believe it would close enough & suit most owners. or at least be a good starting point ?
why does everyone want to cloud the horizion ?
Forgive me if I'm off base on this, but don't most of our awesome vendors pretty much supply this information? Especially if you were ordering from them?
One thing I have noticed regarding our retro-cruisers, is that there is NOT a shootout, persay, as you would find in a typical automobile rag.
Vendors are you listening?
For instance, take a stock carb bonnie, run a muffler shootout, or copyright the info and post it up...8 different slip on's. OF course this could turn into a jet changing headache, but I believe this is what Sporty is starting to hint at. A sound vs. HP trade off.
To go a bit deeper, I think you are looking for a project list as to achieve different levels of performance clearly spelled out with the all appropriate parts to run ball park. The combos are many, and half of the time, seem to be more of a sound preference than all out performance. Again, I believe any of our vendors who do in-house tuning, can provide you with exactly what you're after, and if you buy their products (work with them) I'm sure they would help you to better dial in your ride. Plus this helps to keep these guys around R&D-ing for our sakes.
I can't speak for anyone else, but in just a few days I've gathered that there's pretty much step one.
ARK--by the box with pods or choose your own.
SAIR--poor boy set up (bellacorse), run drag specialty 02 plugs or one of the fancier sets up from our vendors.
slip on's This is full of options...Dom Touring/Torque for this guy
Tune -for fuelie boys Jet's for the carbies.
10-14 rwhp depending on the parts you pick
Roughly $7-800
Next step: ignitor advance
Next step: complimentary cams (or carbs for carb'd guys) add cams later. IT seemed to be pretty close between cams and carbs for hp improvement, with carbs being easier to swap. After one, both, or all three, plan on more jetting and tuning.
These mods add UP TO 8 realistic rwhp...Up To means it doesn't have to give you anything, but some results have shown as much as 8.
Next step becomes a lot pricer at tearing into the engine.
My Bonnie:
I bought my bike, rode it 5 miles and tore into it for the winter.
I had a project list planned as to where I want to go with the bike. This keeps me on track and on budget. For me, it seemed pretty straight forward, hack the stock box, fit DNA pods (Also ordered OBD2 Pieman cable for a later to be purchased tune #11), remove air injection, throw on a set of Dom Touring, and figure a real world 65 rwhp give or take a few.
When I get bored, I'll add a little kick with the ignition advance set up.
Maybe 813 cams later on.
I figured before cams however, I'd dial in the suspension.
Maybe somepoint I might like a gel seat.
Tires---thinking of Sport Demons. Avon's tend to crack, so no deal. Super sticky with a 5000 mile limit. AT only 1400 miles, the two previous owners simply super slabbed it and the back tire is already squaring off (Metzlers are out)...I like to have this stuff planned out. So much for buying the bike because of its radials.
Your matrix heirarchy of performance:
While a matrix would look good to justify the metrics of parts combined (would make white-collar mgmt. happy), it still would be teetering on the nebulous side. There are a lot of different paths to take in order to achieve the same level of rwhp gains.
