Engine service questions 1994 FE600

With no history on the bike except that it's a bit hard to start and with an upcoming tear down/status check I have the following questions:

1. I have read here that the cam follower bearings often go bad and should be replaced periodically. Is it enough to inspect them or should they be replaced anyway?

2. Is this older config with dual valve springs as "bad" as the later config with single harder tapered springs? Would taffmeisters dual spring kit improve bearing life? And do they fit without machining?

3. Is it enough to inspect the cam chain (that tensioner is not all the way in)?

4. Is it possible to tell the state of the con rod bearing without splitting the engine?

5. Should the piston be replaced or is it enough to inspect? Anything particulary to look for apart from the obvious (scratches etc.)?

6. Anything else that I should take a look at (transmission, clutch...)?

Carb, ignition, wiring valve clearance etc. will of course be cleaned/tuned as far as possible.

Thanks in advance.

A: wait for them to go. your old DVSK are soft like my DVSK are.


2. Is this older config with dual valve springs as "bad" as the later config with single harder tapered springs? Would taffmeisters dual spring kit improve bearing life? And do they fit without machining?
A: as said above - yours are fine but they are also very old.

3. Is it enough to inspect the cam chain (that tensioner is not all the way in)?
A: yes if you have clicks left then it is OK.

4. Is it possible to tell the state of the con rod bearing without splitting the engine?
A: yes, you can. hold the con rod at the little end and slap the crankshaft up underneath upwards slapping both flywheels with the palm of your hand. you can feel 'knocking' but also, press the rod to one side and then try and wobble the rod. 2mm+ = gone. always change the little end.

5. Should the piston be replaced or is it enough to inspect? Anything particulary to look for apart from the obvious (scratches etc.)?
A: usually yes, they are rarely "nice". also check the nikasil lining.

6. Anything else that I should take a look at (transmission, clutch...)?
A: everything, everything is phuqed on the old ones. spend, spend and keep spending.

Carb, ignition, wiring valve clearance etc. will of course be cleaned/tuned as far as possible.

Thanks in advance.

Thank you, Taffy. I hope to have the bike home soon so I can tear it apart. The wössner piston kit you sell, 95 mm (100330), is available in a, b and c. I guess a is original bore and b and c are OD bores. Am I correct?

yes, just wear rather than overbore
a is new
b is wherever
c is worn

B has a personality disorder and can't tell what it really is. just get an a or a c.
