What are your thoughts on the V-Tec

A couple of years ago I rode my 2005 VFR on the track at Chuckwalla Valley Raceway. The bike did fine, and it was still on the stock suspension, which I weigh too much for. (Down 20lbs tho!!!!) Sorry, where was I? Oh yeah. I was in a group of guys that race on that track and they all had positive things to say about the VFR, and couldn't believe a bike with a centerstand could scoot around the track like that. And I was running PR4 tires to boot. The fifth gen is sportier still. I have not ridden the 8th gen.

In regards to VTEC, they're was an adjustment period, having come off of my Triumph Sprint RS, but once I got used to it, it was fine. In turns I either choose to keep under the VTEC transition, or above it. She's a thirsty girl when she's running all four valves in anger, but still very fun! Chuckwalla was run between 8,000 RPM to redline at all times, mostly 10,000+. I was told by said racers I could easily be in the B group or possibly the A group and that was my very first time at a track. The bike is capable.

My only warning, is that my bike had a light switch throttle coming off idle. I mitigated this to a great degree by syncing the starter valves and removing the PAIR valves and system. I can't remember if removing the flapper valve did anything or not. I removed the snorkel just to hear the intake noise more easily.

I did replace the cam chain tensioner at around 32-36k miles. Pretty easy actually.

I love the looks of the 6th gen, so go for it.

IIRC, for awhile (how many years?), Freddie Spencer used VFR's at his riding school (which I think closed down in 2008). I remember reading numerous articles and posts about how amazing he was, lapping the track while riding 2 up on a VFR (with complete strangers on the back!)... Word was that he passed a Lot of people around the outside while riding 2 up...

 

Opinions on my V-Tec:

I love my '06, bought it because i knew the owner~

So if my buddy had two fuel injection models one V-Tech one Non V-Tech, hell yes i would choose the non V-Tech all day long.

Just give me 4v per cylinder operation all the time/ no need to re-invent the wheel,.. beautiful machine none the less.

 

Can of worms opened again. LOL

 

Im just being honest, love the bike,.. but the V-Tech IMO is well, silly

Just give me all the power all the time pretty please.

 

I don’t like the VTEC either. My power commander is tuned well and does take a lot of the transition out. But would I’d like to have it removed? Absolutely. A lot of people say it doesn’t bother them and that’s fine. For the most part it does not bother me either. But no matter how good you are on smooth throttle, no matter how anyone brags of how smooth they are it still is not smooth power delivery under heavy throttle. For the most part it does not bother me either. But no matter how good you are on smooth throttle, no matter how anyone brags of how smooth they are, it still is an unwanted non- linear power curve.

 

Again, who needs a pipey 4-stroke

 

Im a few weeks in and the 7,000 power surge novelty has worn off,

Its simply power i could have had in a smoother way throughout the entire rpm range.

 

LOL, I remember you said that year or so ago. I still like the reference.

 

VTEC was Honda being, well, Honda. Its technology for the sake of technology. The proof is that they have never bothered to use it on any other motor they build.
I have it and really don’t like it. It is a intrusion in my riding pleasure.
However it does have a couple of good points.
1/ the engine sounds way better running on two valves rather than 4.
2/ the fuel economy on two valves is excellent.

Other than that Honda can cram it up their ass.
If only 5th gen motor could be easily retrofitted....

Keep that Cager Civic crap off Sport Touring bikes!

 

What about the Honda CB400 Super Four Hyper VTEC? They've been building that bike with VTEC since 1999 (and still building them today, I think).

Seems like a nice motorcycle, too bad Honda doesn't sell them here in the U.S. I'd own one if I could.

 

Me I never had a problem at all with the transition to vtec from day one, even before my PCV that only cured the snacthy, yes I said snatchy on off throttle.
The ride with Jay at R3 in the tight canyon we took, always in 2nd some times 3rd, always in the 4 valve meat and spinning it up out of turns gave me a woody. Best ride in 9 years.

Probably not a problem for spirited riding in canyons and hills. I have done a lot of that on my 09.Aggressive riding I can see it being a problem, a low or high side probability definitely increases as you near the limit of traction where you really want a linear power delivery while leaned over. There is a reason countless hours are spent making those pretty dyno charts without dips and spikes.

 

It is one thing to not like the small hicup in the power band, that VTEC can create in an untuned sixth gen, but please stop pretending that you need 4 valve operation at low RPMs. I cringe every time someone writes about "4 valves for all the power all the time" or something along those lines, as if the engine could actually move enough cfm to make use of four valves at lower RPMs and achieve optimal air velocity, while using all four valves at idle to 5 or 6000 rpms.

Sorry, I know it sounds bad ass: "4 valves for all the power all the time!", but no, it doesn't work like that....

 

That's it ... time to ram a bunch of air down that intake with a supercharger ....

 

There is a reason why MotoGP Technical Direction nixed the use of this technology years ago. The Suzuki ball and ramp system is pretty damn ingenious, as well.

 

Sorry candy, I was waiting for you to reply on this. LOL
But I will always take all valves working all of the time. You know there’s lots of ways to use all four of those, variable length velocity stacks, tuning etc. I will take all of them working all the time thank you.
