That says a lot for the S&S bottom ends.   

It sure does, and I have taken a un-welded S&S 4 5/8 stroke crank to 200 HP on a dyno but if I was using it primarily for drag racing (remember this rebuild is my Street Bike which sees occasional track duty) I would get it welded.
My race bike has a S&S prostock crank and aluminum rods that was prepped and welded by Darkhorse.

We ran the the 675 one year at Wyotech. Took out the 640 (113 tc @12.5, 1.63ra) and with no other changes, pulled 10hp more. As a note we picked about 300 rpm more on top. Torque suffered a little but @159hp it was a beast! Not one issue with riding it in the Daytona traffic for the week except for a head light out ticket. Hopefully you wont have wait to long to see smoke.

Thanks, good to know-
BTW, was talking to Truesdale over the weekend and he is going send me a new meg, collector, and baffle as mine is worn out from a lot of years of use.

If anyone is interested, JBV has some Softail and Dyna Guppy pipes available.

You must walk on water! Last time I asked Brian for some help he sent me a design and pipe destructions to make my own!

I've got a call in, we'll see if Mr. Truesdale wants to sell a dyna pipe.

He said they may come tack welded for a customer to finish but we didn't talk at length about it-I think it depended on if the Dyna was forward controls or not-

I've got mids and don't care if it comes tack welded or complete. Could you put in a word for me Paul? I'd much rather have a legacy pipe than a throw away... If you need goals to put in a word, I'm confident I meet the power requirement.

Sorry for muddying your thread won't happen again, I just about lost it when you posted "dyna guppy"

Those dual carbs are Nasty!!!

Guys are already asking me so I'm telling people to email JBV Racing and give them your specs (forwards or mids, motor etc) and JBV understands they may be getting correspondence and to hopefully follow up quickly via email... Remember I'm just the messenger and have no real leverage but will do what I can-

what the bore and stroke on a 126? What kinda rpms can one turn?

4.375 Bore-4.187 stroke
RPM's, Mine with the .640's was done at 6,400 but Mercs 126' with .640's looks like it pulls to 6,600- http://harleytechtalk.com/htt/index.php/topic,71477.0.html

Don't know what my new re-build will pull to, but maybe a little more...

Let's just say he is putting a little more focus into the Guppy side of things-he even mentioned having his buddy pull his bagger into his shop for mock up purposes to finally do a bagger Guppy, who knows...

Thanks for info Morris, sure wish S&S had a case out for 06-up dyna like they do for the touring bikes

Paul,

I am not sure why that dyno graph stops around 6600rpm, but either my tach/ECM is off or the dyno is off, I have the redline set at 7000rpm and took the runs right to cut off at 7k.

I am not sure what's going on there, maybe the dyno isn't getting the correct info??

My twin cam FXR motor was smoking after nearly 8 years or hard riding so we did a tear down. So far found a bad valve guide seal, bad o ring on the gear drive pump and possibly a sticky/obstructed check valve on the pump supply side, and the rings are showing their age. Lots of oil in cam chest and quite a bit of sumping. Still some more inspection to do but no major damage and bottom end looks good. It is an amazing engine and look forward to getting it back on the road as it has been so good to me for so many years.
Going to bump compression with a piston upgrade (.10 over) but still run pump gas, .675 ez starts, S&S premium lifters with limiters and B2 heads have been sent out for some work as well as new springs and valves.
Hopefully won't be long till we get it all back together. Stay tuned.

I'd say you got your money's worth after 8 years of enjoyment! The new build sounds like a homerun also. Thanks for posting on the Guppy. I'm sure orders are going to be pouring in.

what material are your fuel lines made of??  looks like braided vinyl for main feed and clear pvc for splits?  have you used these lines/materials before and how do they hold up to heat and fuel?  thanks

Thanks to DB Choppers who got me a smokin deal on the motor and the meticulous assembly setting up everything on point.
Quality parts, assembly, tune, routine maintenance and a rider that knows when not to push the equipment over its limits all working together-plus a little luck.
After 3-4 years I thought for sure I was going to blow it up but it never did.
Just kept hummin along...

Main fuel lines are those S&S lines that have a curve at the end to go up into the bowls. I run a dual Pingle Guzzler which feeds each line. The vinyl is just a heat barrier sleeve. On my other bike I run Tygon fuel line which is fed thru an insulated sleeve.
The vents are PVC which I replace every 6 months to a year. It works well but it does discolor from heat and UV sunlight.
The other small lines are the thunder jet lines and I use that material for the bowl vents as well.

  Are the carbs E or G's? Is the dual intake manifold one piece or two? Nice package, and it does look nasty.
I run the std G with dual S&S air filter unit on my 124. I like the looks, but crave the nasty!! Buffalo

Thx-
I build my stuff for function first, and if it looks good then that's a bonus.
Modified G's, single piece manifold.
Here is how it looks with the stacks-

Head update-
Bigger valves being installed (custom made to SA Racing specs), flow testing and porting (street port-not race) new guides and seals, new springs, cylinders being bored to fit .10 over pistons.
Allstaedt is checking valve pockets, cc's, etc...

Where're you landing with compression statically?

Sounds BA

Not sure yet-
Chris Rivas runs his street bike at 13:1 on California Pump with no issues and said I could run mine up there as well as long as it's tuned properly.
We will see how it all shakes out after SA does his work but I don't mind running 11.5-13:1 with my EZ starts, super efficient heads and light weight bike with a good tune-

Porting and cylinder head modification work complete by SA on B2's-Getting closer...

Hey pm. What front end is that on your fxr.

Did you have to change spring rate or anything else for the difference in weight of the two bikes
