Goodbye to a good 1250 engine

[strokerjlk]

This bike has been on the track since 2006
Literally had over 1000 passes on it .
It has been a good motor , and been in the money a lot . Not alot of money , just in the money a lot 

[Panzer]

WOW, right through the case.
That's about right, broken at the stress point.
The engine did you well.

[Durwood]

  RIP

[WhipLash96]

Man that sucks. But now you get build a bigger one.

According to Ron Dickey . Your correct the front rod breaks where mine did
The rear at the base .

[strokerjlk]

Yes I do .
Gonna do a Axtell 88 ci . With ductile Iron cylinders

I am considering going bigger on mine once I get my clutch issue resolved. Think I am going with hammer performance though.

cant go wrong there.
same cylinders.

[rigidthumper]

Those little 88"ers run very well.  Mine is still out there, and I hope whoever stole it is enjoying my efforts. Fukkers.

That sucks
Had some skumbags steal a Stroker shovel of mine . Know just how you feel .

[strokerjlk]

What else was the build robin? And what did it do power wise ?

[mayor]

ouch...that suxs.   

[rigidthumper]

What else was the build robin? And what did it do power wise ?

05 883, NRHS head work, Axtell 88" cylinders w/flat top pistons, SE 575 cams, ST2-1, Pingle air shifter & light, DTT ign, 45 Mik, PM Chicane wheels, Shinko tires. 102TQ/115HP.

Thanks Robin
Kinda the same as what I am doing . 575 cams with a .500 dome piston .

[rigidthumper]

That 1/2" dome should get things moving pretty well.  Shooting for 11:1 corrected?

As much compression as I can get .
Kirby is opening up the XB heads for the bigger bore , and cutting the new 30 deg radius .
It needs intake valves as well. Once he gets his hands on them , . We can determine compression.
Was hoping for around 120 hp .
As of right now I plan on using the HO 575's . But eventually would like to use a more right side set of cams

[rigidthumper]

The RS 643s might fit the bill at 13:1

That's what I was thinking too
Don't know about clearance yet though .

[Maxxx]

ouch!!  what rpm did it let go at?

[strokerjlk]

ouch!!  what rpm did it let go at?

Fortually it was right after the burnout .
Engine was idling .

[strokerjlk]

Gonna go with stock rods again . 

[Maxxx]

 shooting for another 1000 runs..    
I keep waiting for mine to do that at 7500 rpm! 

[Durwood]

Too bad they don't bolt the twin cam flywheels together

[strokerjlk]

Figured you would notice the ultima flywheels in the background

[aswracing]

Those new skinny neck rods as pictured are actually stronger believe it or not ... according to my contact at PDC anyway.

The late Buell/XR crank is much improved and cheaper too:



1.5" pin. Rods made from the same material as used in the XBRR 9000rpm motor. The crank runs about $650. Can be fitted to 91-99, bolt-in for 04-up.

Thanks Aaron . That's kinda comforting .
Any rods cheaper than Carrillo you recommend ?

[strokerjlk]

76 ci pistons vs 88ci pistons

[Maxxx]

nice.. what brand are those 88s?

[strokerjlk]

nice.. what brand are those 88s?

JE pistons , for Axtell ductile iron cylinders

[strokerjlk]

some WFO porn

[Wicked]

Now THAT is fine porn.... 

[Carl 1969]

That 88's gonna be a beast. I got to ride a shop mule that pushed off 97hp/102tq & yowza.

Just outta curiosity, has anyone ever combined a S&S stroker flywheel with the Axtell kit? I know there's little to know room in a OEM frame, but an aftermarket rigid's a whole different ballgame. Have often thought a 4.25 or 4.625 'wheel with those Axtell slugs would be a hoot...

I think the 4.25 or 97 ci is doable
don't know about the 4,624 105.6 ci
would have to use a S&S case for either one.
I hope to have a little more than 97 hp  I had 99 hp 82 tq with the 76 ci off the spray .
not sure what it will do really 

[Carl 1969]

Cool.

That 97/102 Sporty was back in '97, so I imagine folks are getting more out of 'em nowadays. That bike was running heads done by one of the guys involved with JET early on, with N6 cams, Super G & Thunderheader.

Can't imagine sprayin' one of those monsters. Little beast would loft the front, rolling on the throttle in 4th. Builder said it was frightening trying to make a pass with the stock Sportster chassis.

[strokerjlk]

Sounds like a brute
I don't plan on running n2o on this motor . At least for a while .
Before I got the progressive controller on the 1250 motor . The first time I brought the n2o in at full % in 1 st gear out of the hole , it hit the wheelie bar so hard it raised both tires off the ground .

[Carl 1969]

Bet that had you mining seat foam.

[strokerjlk]

Heads are back from Kirby .
Opened up and 30 deg cut again . Along with a new valve and valve job .
Looking good kirby 

[strokerjlk]

Gonna test this carb. S/A modified S&S D
3 thunder jets

[Durwood]

Are you going to be able to make the last Bowling green race?

[strokerjlk]

Are you going to be able to make the last Bowling green race?

IDK.
At this point I am not in a rush anymore .
If I don't get it ready O well  , I am having a blast with the bagger .

Then, i'd order some good rods and make it bullet proof...

[laserp]

Hey Jim. Been off line most of the summer. Good to see you're putting the sporty back together. 

[Durwood]

Come on Jim, give us some more pics and a video of it running, You light that 88"er yet? I know it's in the frame......

[strokerjlk]

Yes it's in the frame .
Still checking clearance's
Waiting on the solid lifters to bleed down . It been two days now .
