Hi all,
I have been lurking for a while and modding my bike in secret so I thought now is a good time to start my build thread.
The driver :
I got a Honda NX 125 for a year, then my bigger bike license and a '95 Suzuki GSX 750 Inazuma wich was poor on MPG (6 L / 100 km minimum) it was bare stock.
Then I went for a '97 Suzuki Freewind (revised 650 single from a newer DR in a more street oriented trim) wich was motarded and got a free flowing exhaust.
I soon fitted with a +1 front sprocket and my best was around 4l / 100.
Then I swapped it for a '81 BMW R65. It is still in the stabble since it needs some work done.
Because the R65 being on rest and having got the bug of hypermilling, I got a Honda Helix. I got it for a year, averaged 3.4 to the 100 and best 3.2. It was stock.
I thought the handling was crap, maintenance difficult and MPG potential was not there because of the CVT so I replaced it with a "proper bike" : the GN.
The bike :
'94 GN 250 with 54K Kms on the clock, a small wind screen and lower handlebars.
When I got it, I lowered the fork 1", lowered the mud guard to have it closer to the front tire as I replaced it, adjusted the windscreen to give it more of an angle then fitted a +1 front sprocket.
I also reworked the air filter case to make it more hi flowing.
Then I fitted a new chain and a -3 rear sprocket.
A few weeks back I went far a cardboard partial tail.
It's been very promising and rewarding in a sort of way ...
Planned mod are :
a bigger rear wheel (16" to 17 or 18"),
clip on handlebars,
Guzzi V8 replica dustbin fairing,
NACA hood for engine cooling,
much higher CR 10.5 to 1),
DR 350 gearbox / bottom end (longer stroke to give 282 cm3 instead of 250, oil cooling and 6 speed gearbox).
The 100mph target (up from 83) is (in my opinion) the other side of the coin of fuel efficiency.
If I can make her go that fast on stock(ish) internals, then she shall return high mpg at usual lower speeds.
I'll be updating this post with pictures pretty soon.
