Topic: cam tensioner parts question

[Burnboy]

does the part pictured come in different sizes on different years? I just ordered a replacement one and its about 2 inches shorter han the one that came out of my bike.

Which bike?  Which year?  Where did you get the part number you ordered?

[Burnboy]

i have a 75 750. i got the replacement part off ebay so no model number.

[OldSchool_IsCool]

So no part number on the part?

[Burnboy]

yes

[Burnboy]

says it was off a 72

[OldSchool_IsCool]

'fraid I don't know the 750 internals that well.  I'm sure someone will come along and can answer your question spot on.

Yeah mate, don't panic, the longer cam chain tensioner was just an evoluntionary improvement made by Honda, either one will work in your bike. Cheers, Terry.

Terry has it right. The lower end was shortened at the K5 model, probably to save money on Honda's part. Although it shortens the guided travel on the way down to the crank, it doesn't appear to bother the engine much. If anything, it should reduce a tiny bit of friction on the cam chain by removing about 1" of guide length.

Think of it as adding .01 HP back to the engine.
