VTEC upgrade

[VIVIAN]

Hi, Anyone there who can tell me if it's possible to transform a CB400L from 2004 into a Vtec version? If possible where and what would be the cost? Thanks.

Wait a minute.

There's something lost in translation.

2004 CB400 is already a Vtec.

Hi, I wish you were right, but the CB400 L is a non Vtec version. I was myself fooled by the vendor (Pang's motor on west coast). I happen to learn that L version is a basic version of SF. I also comes with normal shock absorber (not the showa with Gas), no secure key, smaller light, and a few other stuff. The engine is the same as Vtec 2, but without Vtec. I hope this explains.

Honda CB400L, as budget as possible.....

 

is possible to convert, just $$$ issue.

In fact, I don't mind the secure key, light, shocks, smaller tires, I would just like to know if possible and what would be the cost. The engine block is the same and when comparing with Vtec (right side), it doesn't seem to much spare parts to change. Any one has an idea?

You cannot just "fit" a VTEC "part" onto a non-VTEC engine... Do some research on how VTEC works, then think if it is possible or not.

 

Short of changing the bike, I'd suggest to just learn to enjoy the ride.

Screaming VTEC is orgasmic..

i am not sure whether engine mounting VTEC and non-VTEV are same,

same engine mounting just swap it at the same time remain engine serial number.

Actually I felt Vtec for motorcycle is just a gimmick. It works by using 8 valves at low RPM range and uses all 16 valves at a preset higher RPM range.

 

A non vtec engine also uses all 16 valves at all RPM range. So actually, power at higher rpm range, non vtec and vtec is the same. Vtec engine will not be more powerful than non Vtec. However at low rpm range, Vtec engine might have better fuel comsuption. I understand the feeling when Vtec open and you can hear the different tone, sound shiok. But actually a non-Vtec enigne is already like a Vtec always on engine.

 

For car then is different. The cam works in 3 stages (dunno about the latest iVtec) where it works by allowing more air and fuel into the engine at higher rpm where the engine will get the "boost" in power.

 

So I will say, stick to the normal non-vtec engine.

yah....

Bike's VTEC just a "feeling" there that make ppl misunderstanding the VTEC is "more powerful"....

 

i am owned non-Vtec and test ride Vtec before.

my opinion:-

true performance, look for Non-Vtec

best FC, look for Vtec.

 

 

NOTE:-

hopefully there are not ppl misunderstand Honda Bike's VTEC(Hyper Vtec) and Car's Vtec.

I owned Ver S and Spec 2 before.

The vtec are rubbish.. Why? Power the same and vtec fuel consumption is terrible....

Ver S around 26km/l

Spec 2 around 20km/l

Yes, the vtec change over sound is great..Last you for a couple of weeks that's about it..At 100kph either here or there at 6-7000 rpm. Is a pain...

Hi Guys, Thanks you very much for all your input, I learnt quite a lot. Finally I may indeed just stick to non Vtec. Anyway, it's just temporary until next January, where I intend to upgrade to class 2. Thanks Folks! V'

Yup. Totally agree.
