what motor?

[pitpro140bf]

hey guys, i have a 2009 pitpro 140 bigfoot, and i want to put a gpx 160 in it, would the gpx 160 bolt straight in?
thanks

as far as i know it should bolt straight up, i know for sure the yx motors have CRF style mounts so if you can confirm your frame has the CRF style mounts then yes it will

i would assume so man! my mate has a 160xr and i have a 150xr and as far as i can tell, the bikes are exactly the same accept for the engine!

the 160 YX motor should fit, but for reliability, i'd go with a 155Z... they seem to be getting better reports.

But 155 is a lower number than 160 so the 160 must be more better and more faster.

what about the valve problems with the valve stems? can anyone shed some light on that please?

Ba ha ha ha ha ha ha.... Pluz the 155 has a Z after it, and Zed is the last letter in the alphabet, so it probably always comes last too...
Mate just stroke and bore a 160... 184's are THE best beginners motors..
