So I have an 81 atc185 engine that needs boring, so I figured lets get creative. I love Hondas dependability, so I am liking the idea of all oe honda parts. I've done some searching but the technicals have me wondering.
My theory is an overbore xr185 piston, with an Xr200 cam and carburetor. The xr piston is domed and 10.1:1 compression. I'm curious if anyone knows if the xr piston and bigger cam will bend valves or is it doable?
Or, if that doesn't work, would a xl185 flat top piston with a xr200 cam and carb.
I'm sure I'll get some weird looks or comments, but I'm curious how "big" I can go with Honda parts. I'm not interested in new topends as my cyl and head are peachy, so just cam and piston.
Does anybody have any pointers or personal experience with these cmbinations?
Thanks for any and all help, info, or pictures.
