This is a 660 engine with the following done.

Crankworks rebuilt crank with carrillo rod and keyed counter balance gear.

Xmf middle drive gear support.

Grizzly middle drive gear.

Benchmark 693 piston kit. Pump gas friendly.

Racers edge cnc head with +1mm kibblewhite valves.

Pdm head stud or Kms head bolt and base bolt kits, I don't remember which.

I'm not sure what cam we ended up with, but I know it was a big high power one. I'll update the post when
I get that info. It's either a big ass megacycle or big ass web cam.

Primary and secondary clutches are not included. They have been machined and will not work with the stock belt. Stock wet clutch is installed.

Engine was assembled by benchmark. It was to go into my race rhino but I'm done racing. Time to sell it all for trophy kart parts.

No hours on engine.

$3500.

It's in phoenix and I dont really want to ship it.

I had a MIKUNI 45 and 48. Both worked well. I have the same engine in my play rhino less the good rod and grizzly gears. I run the 45 on it. It had a little more than 60 hp on my crank dyno last time I tested it, not sure at the rear wheels. Haven't tested one lately, changed the dyno over to trophy kart duty now.

Regardless of Grizzly anything I will tell you right now I have no vested interest in the what so ever and if I were you I would get this motor in a heartbeat instead of re-building your own....

I have told a bunch of my friends and customers about it already and I am surprised he still has it...
