Hey Guys,
When I bought my 05 1200R, the dealer had already done motor work.

I don't know what these cams are or any specs.
Can someone tell me from the p/n what they are?

25197-04 XL Cam Set
They also installed 22244-04 Piston Rings and 18013-03 Valve springs.
Any info would be appreciated.

Found in the on-line SE catalog:

Those are the SE "E" cams. Sometimes called the SE .551" cams. Same specs as the Buell XB-12 cams:

Duration: 249 / 249

Max Lift: 551" / .551"

TDC Lift: .197" / .122"

INT. 25 / 44
EXT. 59 / 10

I had a set of those in my engine, but they were noisy, so I changed them to a set from Zippers.

The Zippers are the "Red Shift" cams. They take your stock cams, grind off the lobes and weld on new lobes. If your stock cams were quiet, so will the new cams be ... since they really are your stock cams with new lobes.

The reason the SE .551" cams are so noisy is because of loose clearancing between the cam gears. Also, the Andrews N4s perform about the same as the SE .551s, but I understand they are alot quieter.

y did they change the piston rings and valve springs?? the stock springs are made to handle the lift of the 'E' cams, hence their 'bolt-in' name... just wondering...

Those E cams will work with the stock springs. The buell XB has the same valve train. (same P#s) 18013-03 are beehive springs, like stock, but made for up to .575 lift and have 208lbs installed pressure. that's out of my SE catalog.

The rings I don't know much about except they are standard bore. Of course there is no reason to re-ring it for a cam change. :dunno

Perhaps someone more knowledgable can chime in as well.

Bueller.....Bueller.....Anyone? :frownthre
