CCT

[silvergoose]

I know as a full grown man I can choose to ignore any topic, but the talk about the CCT is everyday the same old saw.

First, a manual CCT fails in so many ways I can not understand why people flock to this.

Fail #1. Are you a good enough tech to know what is the correct chain tension?
Fail #2. What is the chain slack at operating temp, did you set the slack at temp or just room temp?
Fail #3. If the manual CCT is so good why doesn't Yamaha save a few dollars and put in place at the start.
Fail #4. If Oil pressure controlled CCT is bad why don't cars have manually adjusted valves?
Fail #5. Some have stated that the engine runs more quite, Have you ever listened to and engine with manually
adjusted valves run quite? If you have an air cooled engine running quite after a valve adjustment, maybe they are
set to close and go to zero gap as the heat goes up.

While I could give two hoots as to what you do, it bothers me that so many jump on a subject with little or no practical experience. It's your money, but if you think you are so mechanically inclined why do so many allow an oil pressure controlled transmission shift your car?

End if rant. ::021::

Are engines converted to manual CCT covered by the manufacturers warranty?


Great image, Kindergarten stuff.

Good luck. A discussion uses words.

If you were to have the cam timing go out or a valve-related issue, it'd be up to you to prove it was not related to the M-CCT. If the problem were a bad clutch, transmission, or something else not related to the valve train the warranty should still be honored. Somewhere in between those two is in the discretion of the dealer and their area representative.

First, a manual CCT fails in so many ways I can not understand why people flock to this.

Fail #1. Are you a good enough tech to know what is the correct chain tension?
Yes sir.
Fail #2. What is the chain slack at operating temp, did you set the slack at temp or just room temp?
Warm engine.
Fail #3. If the manual CCT is so good why doesn't Yamaha save a few dollars and put in place at the start.
If the automatic tensioner was soo good they wouldn't fail and blow engines all to hell.
Fail #4. If Oil pressure controlled CCT is bad why don't cars have manually adjusted valves?
There's your apples to oranges comparison. Talk to GM or Ford, I'm sure they will give you a funny look.
Fail #5. Some have stated that the engine runs more quite, Have you ever listened to and engine with manually
adjusted valves run quite?YES If you have an air cooled engine running quite after a valve adjustment, maybe they are
set to close and go to zero gap as the heat goes up. And maybe they are adjusted properly

While I could give two hoots as to what you do, it bothers me that so many jump on a subject with little or no practical experience. So you have a magic computer screen that tells one's mechanical experience. Cool!It's your money, but if you think you are so mechanically inclined why do so many allow an oil pressure controlled transmission shift your car? That's great big apples and oranges. Makes one's head hurt just to think about it.

If you don't understand the difference between a manual and an automatic tensioner, ya might want to keep the tool box closed.

Speaking of practical experience, do you actually understand the difference between hydraulic vs. manual valve adjustments and hydraulic vs. manual cam chain tensioners? You seem to be confusing two completely different and independent systems. A given engine can have manual valve clearance adjustments and an automatic cam chain tensioner, such as the case for the Super Tenere, or vise versa.

If you are asking me about valve lash settings, yes. I do know the difference between cam chain adjustments and valve lash.

Oldrider, maybe it is you that has the magical computer screen. I was only asking questions, but the answers re more about winner wagging than fact evidence.

How many Yamaha engines have blown up due to the automatic cam chain adjusters? If the number is high enough what about a recall program?

Apparently this subject is very guarded. Let me ask this question: What is the position of the m-cct to cover an engine problem related to the chain? Will the m-cct manufactures go to bat for a customer in a warranty question?

Just asking.

Good Luck
