New JIMS® 135″ Twin Cam Race Engine

Jims has an excellent proven track record with race engines and based on this experience just released a new 135″ (2.2-liter) monster that you can bolt right into a stock frame.

Built around a 4-5/16” Bore x 4-5/8” Stroke, it’s a “thick wall” engine with larger cylinders and increased fin pack for better cooling. Other features include Increased Press & Race Welded Flywheels, Billet Cam Plate with High Flow Oil Pump, Forged Rocker Support Plate with Roller Rocker Arms, ARP® Cylinder Studs and Case Bolts and much more.

This engine can conservatively produce 136 HP and 135 TQ with proper intake, exhaust and tuning. Many of JIMS® race engines are actually producing much more power with customer modifications.

The JIMS® 135” Twin Cam Race Engine is available in Black or Silver and fits all Touring and Dyna models ‘99-Present and Evo models ‘91-’99. JIMS Race Engines are not street legal and are available exclusively through Authorized Harley-Davidson® dealerships. For more information please visit us at Jims USA or call 805-482-6913.

    Not street legal. What if I ride a bike with such an engine in the streets of LA. Will anyone know?

    So S&S and Jims both in bed with HD. I wonder who’s next?

    Lord only knows why anyone would tie themselves to MOCO…. What a shame.. I look to the after market so I don’t have to stand in line with the doctors and lawyers(and other assorted rubs and yuppies)at the dealer

    I bet Zach Ness’ 106″ Lloydz overhead cam Victory motor will beat it.

    Aren’t Jim’s and Screamin’ Eagle synonymous? Jim’s has been a part of MOCO for a long time now. Seems to be a very different relationship than what Eric Buel had.

    If it has the hp and tq it says it does; it’ll beat the 106″ Lloydz Victory. Dunno about the 116″ though…

    I was thinking the same thing!
    Why is being assciated with the MoCo such a bad thing? After all the MoCo builds the original platform.

    My 131 revolution performance hot rod makes 173 h.p.
    Baisley heads, darkhorse crank prep, Bob Wood cams
    This Jims engine must be set up mildly for touring
    My engine is a little too radical for street but it sure pulls hard.
