sorry for two posts,but these are two very diferrent subjects,i found out my quadracer engine is fairly screwed,but i have a pristine cr250 motor here,i have heard people recommend against this because of vibration.cause the cr250 engine has no counter balancer,would this be a huge problem?i dont mind the vibrating,and i knew a guy who put a yz490 motor in a blaster frame,what do you guys think?

 

whys it say u have a quadsport 230 if u say u have a quadracer...i wouldnt put it in a quadsport frame...the 'racer frame at least has some potential of handling well...

 

i used to have a quadsport 230. that was a while back. i own an 87 quadracer,and two banshee's now.im just worried about to much vibration causing cracking
