Subject: 5th gear replacement - first
report
Hi all,
I mentioned a few weeks ago that I was experimenting with the
gears from my Vmax.
Last week I was on a holiday trip to the Vosges (Vogezen) in
France with 15 friends in total.
A good place to try
out some of the settings of the bike. Perfect roads, not much traffic and some
friends with bikes that perform well. (Honda VTR1000-SP1, Yamaha R1 and a
tuned Ducati M900)
The gears shift ok, rpm dropped to about 5100 at
150km/h.
Ideal for long trips, it saves fuel which is
quite expensive here in the Netherlands (f2,71 per liter!!)
The bike pulls less than before, but this is obvious. On the highway
it's ok.
Top speed is about 260km/h (8000rpm) at the
moment. This is not ok yet. The top end of the bike is not optimal yet. I am
working on this this week. Although with this setup the bike will not reach
the red line on the tach. In theory this would be 300km/h...
It was not setup for top speed, but for 5th gear highway
cruising at 120-150km/h
While driving (racing!!) up and down the curved roads the gap
between 4th and 5th is quite large. Flat out in 4th uphill and than shifting
to 5th is no good. The 5th is clearly an overdrive.
Conclusion:
For long trips and high
cruising speeds (120-160km/h, Europe) and "normal" driving this setup is
ok.
When you plan to use the bike for racing and you
need the 5th, the gap between 4 and 5th is too big.
I
think for a very strong engine (1500cc) this is a good setup, for the standard
bikes this will be overkill.
Also low cruising speeds
will bog the engine too much.
Parts used:
gears: 4NK-17251-00 4NK-17151-00
(royal star)
Hindle 4-1 Carbon stealth
Stage 7 kit
Dymag 17" rims
Bridgestone tyres: 170/60-17 (BT57) and 120/60-17 (BT56) I
can sure recommend these for grip! It cost me the footpegs and the lower
fairing of my bike...
Any comments?
