do the 850 timing chain need replaced?

[Guest]

calculating how much i need to finish my rebuild..

ive read somewhere the timing chain/components dont wear much on these engines...

is there a way of checking my bikes chain specs?...it needs a upper end rebuild(smokes to high hell) and the inside trans seals leak...and maybe a new piston and wrist pin..(spark plug gets shut just a hair at times)

the bike runs great as it sits...just dont wanna put money into it if it wont need it

Yes and you'll find the "pin to pin' measurement in the shop manual.

This "new English" has always left me scratching my head.

"need replaced"?

Not as bad as todays use of "like", or "ya know", but in the same conversation.

Are you implying the piston is hitting the spark plug?

seems to be so...it dont affect it...not sure when it happens...just when i did a compresson check i noticed it

You have bigger troubles than rings and valves. Someone used the wrong pistons, or the connecting rods are too long, rod bearings are shot, worn out of round or something.

Wait, you are using NGK B8ES, correct?

The BP8ES has a protruding tip. I like those in my Commando. I was wondering if they worked in a GS
