question abt the rpm

[Kachua]

i am riding a spec 3

while travelling at 6500rpm, the bike tend to be travelling at a

rather rough acceralation.

I am riding a Spec 2 also riding at 100km/h where the vtec at the open and close @6300rpm is rather rough.

Anyone encounter this problems?

[Vtec 2]

Normal...

ride faster or slower to avoid this rough spot.

So is normal to have this rough spot where the Vtec wan to close or open....

lets say you are going to move off. it is more difficult or less difficult? same theory here. At this point of time the extra valve is going to open and more intake of air and fuel so it will be rough

for me, i dun feel the transition... from normal to vtec rpm all very smooth...

 

but i do feel the difference (power) when the vtec is open...

 

just sharing my personal experience...

[Kachua]

so can i say it is normal to be rough

 

and also when my rpn is 6500, my speed is only abt 100km/h

 

it is correct.(my ideling is abt less then 1000rpm)

Think that is becos u rev quite a lot or gear shifting is fast,

hence the rough spot is short and became unnoticed.

but if u cruise at 90km/h and accelerate slowly to 110km/h,

u will notice that that is a transition period where is not that smoooth.

 

that's my opinion...correct me if i'm wrong.

If u rev pass the transition pt is smooth but if u try staying there then quite rough.

My spec III's rough spot is about 80kmh at 6th gear.
