These motors RIP hard! I have been running one of these in my surf freak and am stoked with their performance. Blue has been refining the sleeve and porting design on this motor for years now and it is right on the money.

These beautiful Big Bore motors are newly built 62t/61x (same configuration as RN '96-'15) 781cc freestyle motors ported and built by Blue/JetManiac. They designed to offer the most freestyle low end power for the best big bore value.

62t cases- freestyle big bore ported and epoxied intake and front stator areas, cases bored and machined to accept our custom big bore sleeves.

61x cylinder- freestyle big bore ported, new JetManiac custom Big Bore sleeves installed and bored to 84-85.5mm, exhaust/head decked

New Pro-X top end with new pistons, rings, and wrist pin bearings
New US quality gaskets
New rebuilt/SBT crank with 1 year unconditional warranty
(have options for hotrods or new oem cranks also)
New OEM crank seals
New carb jets and springs for oem 38's included, and carb tuning specs included
Cases, cylinders, and bedplates (clearanced for bpipe) are sandblasted and then bead blasted, painted and baked on beautiful semigloss black finish

Video here:

These motor are designed to work well with affordable stock dual 38mm carb setup and jets, springs, and carb tuning specs are included.
(Of course, JM BB will also work well with larger carb setups like 46's or larger.)

ADA head with custom ADA/JetManiac domes and complete intake/carb setup package also available.

*We can also rebuild your motor into one like this or trade-in your core motor (crank, cases, cylinder) with usable parts for approx. 400.-500. credit off this motor.

Short block $2680.

(Outright purchase with no core required)

I would like to buy one of these motors. What is the procedure? Do I send my motor in first? Do you guys lighten flywheels? Please let me know at theloneroofer@hotmail.com What prop do you recommend with this motor and stock 38's? Thanks in advance and sorry about the deluge of questions.

Chris we spoke a few weeks ago about doing a BB this fall. I have a question for you, have you ever built any stroker motors using your BB as the platform, say like a 5 mil stroker crank. Just wondering what your take is on that or if it's even a possibility for you to do. Lmk bud, I appreciate all the info so far and your motors are sick, love the lime green
