HILLSIDE 131 twin cam build

[partycrasher]

With the help of the Palmer brothers at Hillside Motorcycle & machine in NY, My JIms 131 is currently undergoing major reconstructive surgery. Hillside custom cylinder head modifications, Horse power inc 62mm TB, 662-2 cams, new wiseco specialty pistons and a few others mods...... to ensure that the new year comes in as fast as a speeding bullett. This "sleeper" bagger should wake the dead when all is said and done. Can't wait!!!

Partycrasher,

Is the 60 mm new ?  If you are using the cam plate that comes with the 131 depending on dates of when you received the motor you may want to verify your cam plate is the latest there were some issues on cam plates failing due to soft materials (per Jim's). 

Hope it turns out well and ushers in a speedy new year !

Didn't know HPI made or created a reworked 60 FBW???

I've talked to Scott about this motor and I am waiting anxiously to see how it turns out 

[rigidthumper]

That would be your basic nuclear ballistic missile!
Better get a Velcro seat and and fuzzy britches!

[ChromeWhore]

What do you speculate the numbers will be? 

[partycrasher]

my stock jims 131 put out about 132tq and 120 hp. at the rear wheel......i would think there will be a good improvement--but dont really know where the numbers will land.

The 662-2 is in the cam chest at this point (btw VERY, VERY similar to a Wood 9F), modified t/body hit the door on 12/30, and the Wiesco pistons are in transit at this point.
Heads are looking very good from the work, and flow testing data we have gathered.
Gettin' closer by the day.

anyone have the info on the cnc heads jims has on their newer 131's      do they flow better than their older ones or the same

[Hillside Motorcycle]

On this particular set, the front head was not bad out of the gate, but the rear flow data, was waaaaaaaaaaay less, in spite of the obivious CNC work that was done.
Not any more, though.

Be great to see some before and after flow data on those heads.  Sounds like a killer set up. The 662-2 has made some very good power in 124's & 117's so should be good to see how it works in a 131.

Have you already converted over to chain. If not  YOU WILL . I'm guessing it will be in the 160+range on the torque side....xzo

I was on the phone with Scott when this motor fired off. I thought a dump truck had driven through the building.

[xzo124]

It's definately going to be a handful  ...xzo

[partycrasher]

I'm told that the heat cycling is complete...

[wurk_truk]
