TL250 Honda

what about a ball roller bearing behind the points,seen that done,slide fit on cam,just seal housing to be machined,would the XL 185/200 steel inset on the other end work as well as bushing there,btw TL head is physically smaller too than XL's circumference,

There isn't much room behind the points and the cover from memory only has the seal area in it but the head has a small extra journal area. The 185 steel bush is the sort of thing that is needed but it is easier to make a new bush from bronze or alloy to fit the space after the cam and head have been re-machined back to round. Maching the head is a real prick as it is deep inside and almost impossible to see let alone measure while it is setup in the mill for line boring.

Hi Everyone,

OK, so I could hear the gears grinding, does this help?   

Let me know if you want more detailed photos? This is a centre port and came to exactly as is, I thought TL 250 so I grabbed it but stand to be corrected.....
