Currently about to reassemble my engine, so i can ride to school and save some money (instead of paying the bus fare..........

)
The engine was dissasembeled due to cam chain rattle and a cylinder/crankcase gasket leak. (CB400F)
I was thinking:
Complete engine gasket set
engine oil seal set
Oil filter
Cam chain guide
Cam chain tensioner
Cam chain damper/rubber
Primary chain (advised by local mc-mechanic) Assuming i can remove the pistons and slide the primary chain out without loosening the crankshaft stretch bolts (which will cost a lot....)
Could i be missing some valve-related items?
Best regards.
