23-2-2018 1125CR cylinder head, XB12SCG Service

26-5-2018 - What did we do today 23-2-2018 Buell 1125CR cylinder head, Buell XB12SCG check and like new

on the 1125 with oil consumption. we cleaned the valves

old seals of

and to clean the head.. the valve spring seats

some time later.. lots off carbon cleaned off the exhaust tracks

as we have broken the seal.. best to replace the base gaskets

cylinder off , looks ok

piston / rings looking ok

removing the base gasket

and cleaning the head gasket

drop of oil under the valve seats

and the valve seals go on

drop of oil on the stem.. and valves back in

  fidely keys.. even smaller than air cooled buell ones

check if seated ok

intake done

this one douse not wanted to play.. pressure off again and readjust the key

checking the slot position.. i noticed some thing strange

need to take the piston off to check

piston pin pulled out

top and 2e ring easy to spot.. topside marked witn N

this was what i noted.. oil ring hold a loose wire

the wire is broken off the oil scraper spacer ring

this ring is there to preven the but ends of the spacer do not slide on top off each other, and so have to less tension to seal ( the oiling problem ) need to order a set new rings for this cylinder
