Good freakin' luck! Lol. I really like mine. Head button and crank timing are only difference from C6/B9. They were really expensive when new. Next time you're at LCRC you can try mine Ed.

Yeah they are not easy to find at all!!! Maybe if enough people ask for them they will bring em back :D

Need a new engine for my Truggy.
I generally run on tight tracks with no grip .
B11 or F11?
Also what about the X11 does anyone run these?
Want a engine that holds a good tune and lasts.
Thanks

Well if you have very low grip the F11 will just be somewhat hard to control. The B11 will be much easier to drive and the X11 would be the most controllable. I myself never tried to run the X11 in a truggy but I do know it's an awesome buggy engine. If your not in need of an engine right now you may want to hold off just a little bit and see what new releases will be coming shortly.

hi chris
can you cofirm the diffrences between the two versions of the f11
piston/liner button and crank/crankcase. and how the diffrences efect
performance and what is the gas mileage like compered to the c6 usa.

HOw do you tell the difference between a USA Etc a guy I know asked if I wanted to buy it was a brand new C6 i saw its shrinked wrapped

Right on top of the head, it has C6 USA, it also has a balanced crank, and a Rody head button,

Let me ask the guy if it was the USA version new what's a good price

I can turn a regular C6 into a USA, or something quite beyond a USA if so desired...tungsten slugged crank and all !

You did Hambones engine, correct?

I would pretty well doubt that it is, it's been a few years since they were out. The F11 engine is a 7 intake ports and 1 exhaust port engine, similar to the old WS7 engine, but the WS7 had different crank, the C6 is a 7 intake ports and 3 exhaust ports, the B11 is pretty much a revised C6, and quite reasonable fuel mileage.

The C6 that Neal Clocked for me is one sweet engine. He lightened and
slugged the crank, lightened the rod, adjusted the squish area of the turbo head button and did his voodoo on the sleeve ports. Even though I
asked him to push it beyond the normal race mod, it astounded me
that an engine with all this screaming power can get the great runtimes
that it does.
I even wanted to see just how far I could push the Clocked C6. So
I dropped down to just a .10mm button shim, 45% Nitro and a ice cold
glowplug. Threw it in a DM-1 and it freaking flys. Gobs of controllable
power throughout the powerband and the top-end never stops pulling.
I've got another C6 ready to be Clocked and I can't wait to get my
hands on a Clocked F-12.

Yes...

The symbol you want to see on the cooling head is the same symbol that is on the top left of this PDF. Plus the part number on the box should be 01006-C6BBIIUSA. The crankshaft in these engines was a Rody tuned Onroad crankshaft, along with the Rody tuned head button. I still have two used ones I run and have been babying the last few years. In all honesty the F11 is pretty close in terms of performance but the C6USA does get better fuel mileage for me.

Can anybody tell me something on the cross 10 motor? Thinking of getting one with 2045 pipe combo. How is the power delivery? How is the bottom end, top end, mileage? Thanks.
