Question for 6th Genearation owners

I'm ready to pull the trigger on a 2004 VFR800, doing some footwork I would apprecite some comments on the chain drive cams and VTEC valve actuation.

VTEC valve actuation

The VFR800 was the first non-JDM motorcycle to use VTEC valve-gear. Honda used VTEC to meet tightening noise and emissions standards and to increase the peak engine horsepower. Based on the VTEC-E system, the simplified motorcycle version of VTEC employs only two of the four valves per cylinder when operating at lower engine speeds. All four valves per cylinder are engaged above approximately 6,800 rpm. This is initiated by an electronically actuated oil spool valve, which send oil pressure to the lifter actuators, which then move the engagement pins into place above the valve stem, allowing the remaining two valves to open. This design allows for variable valve timing as well, since the cam lobe profiles can be made different. After much criticism of the abruptness of power transition, Honda lowered the VTEC activation rpm threshold to 6,400 rpm in 2006. The VTEC disengages two cylinder valves when the engine speed drops again below 6,100 rpm.

Just easier to paste and copy. Is there abrupt power transition on the 2004 model year?? Sorry for putting my first post here but have a very short time frame for purchase, once I own it I will post a proper intro with pic's.

Thanks, Steve

 

I would get the 06 or later. As for abrupt....Merh It feel like super charger to me ound: I like it. Not that I need to ride triple digits all day

 

On the VTEC engagement, It's not that big of a deal really. Nor is the cam chain VS the gear driven cams. Cam chains work just fine but just don't sound as exotic.

That being said, I did not like my 6th gen VFR because of the VTEC. I much preferred the 5th gen engine. If you have never ridden a 5th gen, you'll be fine on a 6th gen. Everything else about the 6th gen is better though. No matter what though, take the bike for a ride before you buy it to see if you like the way it feels.

 

I have an 2004 and the VTEC to me is not an issue. But as previously stated ride it first.

 

I also have an 04: the VTEC kick-in is my favorite part of the bike, not only for the surge in power but also the Sound it makes (via my StainTune exhaust.) It is BadASS

It's a Win/Win

Ride Red!

 

I like turbochargers, the VTEC kick is kind of reminiscent of a spike in boost, therefore I like it :biggrin:

 

I would say it is a little bothersome at first but you get used to it quickly.

 

Steve, so does the bike have any farkles? PCV, pipes, and whats the milage?
It really is no big deal, love when mine kicks in, reminds of my Ford SVT....
But I to have the PCV, smooth the transition out

 

The bike is stock $ 4500.00 with 4250mi 1 adult owner in mint condition, however, was just sold this morning and I missed the boat Thanks guys for your replies and I'll keep looking in the tri-state area for one.

 

Sorry to hear you missed the bike. I had a 04 before getting the 07. The VTEC transition on the 07 is more docile. It's less pronounced. You can still hear the exhaust tune change but the 04 was more like a kick in the but when VTEC engaged. Never had any issues with it, I quite liked it

 

My 2006 is a smooth transition. The exhaust note of s getting less and less noticeable. Keep looking, they are out there!

 

I agree that the transition is really not much of an issue. The power surge really is not that much. The noise is not proportional to the performance. They are a long lasting engine. Mine has something lie 188,000 km or near that. Still going strong. Stronger that the old fugger riding it.

 

Love those wheels you painted to match the blue.

 

I've got an '02 ... first year for VTEC and love it.

I've found that the transition is really depending on how hard you roll the throttle on. Like everyone else said, it's kind of like turbo/supercharger kicking in. I don't mind it at all, and I love hitting it hard - that exhaust note change is wicked.

 

The VTEC kick is half the fun. I have an '02 and it is outstanding - buy the '04, you will not regret it.
