That's the only tight spot, the newer oil pump bolts right up otherwise. But, with a little grinding, it can be done.

- | ==== Un-needed cam chest drain in newer oil pumps ==== | + | ==== Cam chest drain in 77-97 engines ==== |
+ | 98 and up oil pumps will bolt straight up to 77 -97 engines. \\ | ||
+ | However, 77-97 engines drain the cam chest to the crankcase. \\ | ||
+ | '98 and later pumps all have a scavenge inlet in the cam box and therefore your motor's cam box to crankcase drain is not needed and actually not desirable. ((aswracing of the XLFORUM http://xlforum.net/forums/showthread.php?t=559906)) \\ | ||
+ | So a complete update would include plugging that drain. \\ | ||
+ | The '07 Buell pump has a bigger scavenge section than the standard Pro-Flow. \\ | ||
+ | Unless you go to a multi-section Pro-Flow and all the associated plumbing, you're better off with the 07 pump. \\ | ||

+ | ** | ||
+ | There is also another option of modding the oil pump cam drain port instead**. \\ | ||
+ | The cam port on the pump is blocked off. \\ | ||
+ | Currently the only known company that does this mod is Karling Racing in Sweden. \\ | ||
