I came across a deal on some 34" tires I couldn't pass up. I was wondering if anyone has seen or tried to install these on the z force. For what I paid im sure I can make out good just putting for sale.

IMO there just isn't enough stones in a CFM 1000 for 34" tires. Not sure you could do enough to get enough power back even with an ECU flash and any stage-3 clutch work to not be left behind by the other guys. I wouldn't do any more then 27s on a 500, 28s on an 800 and 30s on a 1000...maybe 32s if the weight was in the 30s range. Besides..not sure they won't rub on the old chassis. That's just me.

Portals with a massive reduction lol

That was my thoughts too, I have a guy coming tomorrow to check them out, thanks for replying!
