CRF230L valve guides only in oversize but no oversize valves


Recommended Posts

Hi guys, 

 

I am doing a complete rebuild of my CRF230L bottom and top. I am living in South East Asia and all the engines I looked on before deciding to fork some serious cash on the crank, piston etc were utter rubbish. 

I had a bent intake valve and found standard size replacement valves from Honda 14711-KBB-900 they fit both 230F and 230L but the valve guides come only in oversize for 230L: 12204-439-305 . whereas the CRF230F has both standard and oversize: 

12204-KW1-405, 12206-KW1-315.
 
Any idea if I can use the standard sized CRF230F guide with my new valve on CRF230L?

Thanks

Correct me if im wrong but I think oversize is referring to oversize OD not ID.

If you are going to fit a valve with larger stem you will need to bore the guide and get larger hardware IE spring cover and keepers and valve seals.

larger OD guides are for replacing bad worn OE guides.
