V-tech- Over all positive or negative?

I must admit that I find it somewhat hard to understand where the concerns stem from the level of noise from gear-driven cams. They aren't particularly loud; I had a CB-1 which had gear-driven cams, it when it was at idle, it was so quiet and smooth it was like a fine Swiss watch. You could barely hear it. Even non-motorcyclists would comment on how quiet it was. And it had a bare engine that was not covered by bodywork.

The induction noise in my 600RR is MUCH louder than the cam gear-whine on the VFR.

Let's not forget the racket that dry clutches from high-end Ducatis make! Now, that's loud!

 

Gear Driven Cams... You better believe you can hear those things. Especially if your listening for it. They remind me of a radio controlled car. The sound IMO interferes with the sound of the engine, especially just cruising around.

I regards to reliability... The failures of that past were just that, in the past. I think it was an unnecessary fix for what could have been dealt with with proper engineering. In todays world, gear driven cams are not important. The technology has been improved, they have learned from their mistakes. With some proper maintenance a chain driven cam system will last just as long.

 

But there not a bad thing....

 

There was a post on this subject about a year ago. There have certainly been failures associated with gear driven cams. They are extremely rare though. Any moving part in an engine is a possible point of failure. The bonus with them is that they are zero maintenance. In general, I would probably agree with you that they are more reliable than chain driven systems.

 

Are you kidding? The noise that gear driven cams make is extremely prominent. If I have my 2nd Gen running next to my 6th Gen, you can't even hear the 6th Gen because all I can hear is the gear whine from the 2nd Gen. My buddy bought my 5th Gen and we laugh about the same thing. However, I LOVE the sound of the gear driven cams and would never complain about it being "noise pollution".

 

I gotta say those gear driven cams do sound good, make the bike even more unique. but i don't think you'll see em in any new gens. more expensive and not as efficient as a chain also honda seems to strive to produce the quietest street bike they can.

 

I like your signature text Stewart, way to represent the common bond. Very nice.

 

Chain drive does have a few very small advantages over gear drive. Chain drives weigh less, they are much quieter, and they probably have less inertia (albeit slight).

Though Honda doesn't take advantage of this, chain drives can easily accept a variable cam timing scheme using a tensioner that moves the "slack" from one side of the chain to the other. Doing something similar with a gear would require a heavy floating assembly much like the VTC mechanism on Honda's i-VTEC system.

 

Makes total sense that anything mechanical that moves would fail given time or mistake in manufacture but my comment was more related to not personally known anyone in the local VFR community that has had a GDC failure actually have not known any Gen 3, 4 or 5 owners even with big mileage that have had any kind of engine related mechanical failure. ( excluding the odd abused clutch of course :wink: )

 

6th Gen battalion flag = :yield: New battle flag for the French to wave :blah:

talk a good talk but 6th gen still a sub-performing out dated product !

 

opcorn: Ok i'll play :biggrin:

While there maybe some truth the current VFR is overdue a year or two for replacement but if I were in need of a new motorcycle would still pick the Gen 6 over that rattling bag of bolts Triumph ST and if HP was the major requirment would easly choose the K1200R or ZX-14 over the ST.

 

Ah come on TAZ... Just cause the 6th gen is by far the best bike on the planet there's no need to call it names.

It looks like you have 1-1/2 6th gens... You should really sell them... I'm sure they can't stand to be sitting beside all that super performing, state of the art equipment you got there... uke:

 

The flag is an attempt to inject a little humor into what was becoming an acrimonious debate. Taz, don't take us backwards into a p!ssing contest. At some point, trashing my bike because it doesn't excel in categories that you consider important becomes a personal criticism of me. After all, I am satisfied with my bike. Am I stupid for feeling satisified? Or are you a snob? These are questions that we really don't need to explore on this forum. So, let's just maintain a sense of humor.

Perhaps this thread should be locked and we can move on to less controversial topics, like what kind of oil is best . . . .

 

Or oil filter... Or tires...

 

My oil and tires are better than all of yours, so don't even bother starting another thread.

But agree.. this and the VFR 1000 thread are getting old.

 

Never intended a personal attack & to each his own on what they like,

That being said, I was joking about the signature flag AAAAAAAaaaaaaand this thread was about the V-tec good or bad, which was point & right to point out that on a economical & mechanical view it was & is a useless thing & have argued my point on that.
It's a forum, & topics are talked about, Sorry if my knowledge of bikes & willingness to educate others bothers you, but like I said - No personal attack was ever meant or made.

As in other threads I reply to, no personal attack there, just info, facts, my knowledge, & common sense remarks.

I say go ahead & lock it down but as all things like tyre & oil threads, they'll come back to haunt you :frusty: !


:closed_2:

 

I didn't have 4 days to read all 7 PAGES of this thread, but I LOVE my 6 Gen bike. I LOVE my VTEC.
BTW, Is this the longest thread ever on VFRW?

 

I don't know if it's the longest because I've only been around here for three months, however I would be willing to hazard a guess that is probably become one of the most monotonous. I'm just surprised it hasn't ended up over at VFRD like that other monotonous thread did. :rip:

Ok, let the crying game begin!:faint:

 

:biggrin: :hug:

 

Old threads never die, they just fade away....
