10.000km done with 3 speed 'gearbox' on 'gt rst'

[alexander]

hi from new zealand, just done 10.000km in 12 month with 60.000 meters (60km) accumulated altitude (thats up only)
on a 31ccm honda gx with a reductionbox and a 3 speed sturmer archer copy (shimano) gearboxbox/hub.... on a 15 year old 'gt rst' (power through chain drive, of course, only way to go...see motorcycle history....don't need to reinvent the wheel....) ....yeeeha ( YEEEEEHAAA). done some epic missions offroad, ride weekly from sealevel to 800 meters above sealevel (middle of summer, middle of day=sorts the 'good setup out from the bad ones'), and do weekly a daily trip of 150km, on top of the rest.... (its my only vehicle at the moment....) the 'second hand 3 speed box' lasted 6500km until the first gear gave up (in the middle of a '6 hour singletrack epic'.... up and down....) and replaced it with parts from another hub. good to know that its not the most used gear (third) that goes first,meaning, one can carry on....(e.g. for expedition use....) anyway, about to create 'mark 2' but can't tell you more until its finished. however, having ridden on an old bmw motorbike to the northern and southern most motorcycle rally on earth..... (norway and nz (but not overland from one to the other, (i planned to do that but the embassy of iran (25 years ago when in war with iraq) stole my passport...) and 10.000km in 2 month on my longest trip....ra ra...., my point being that there is no point hanging around the year 1900 when the 'Bicycles with motor dudes' were about to invent the 2 speed and then the 3 speed gearbox. (do you hear of any 'one speed motorcycle' today?) if you want to go somewhere, anywhere, ' you NEED a gearbox and 3 speed is the minimum (8 speed better, rohloff 14 speed' would be awesome (would only use the 8 top gears on the road....) so boys: 'get at it',
and 'go hard', because: 'one speed sucks'. also: electric bikes.....what can i say.....put it this way: i carry 2 alu bottles with fuel on the bike, which gives me alltogether 2 litres of fuel that lasts 120km and can fuel up 'anywhere' but when you run out of electric juice you are f....kd....you know what i mean.... not even to talk about '2 strokes, having to mix fuel and oil every time you fuel up....and the oil being blown into the air with every stroke..... and noice.... vibration....etc. etc. thats why nobody, but the hardcore extreme offroad mx boys using 2 strokes these days (and road racing GP 250ccm etc. having to change to 4 strokes....) ('stuffed' (same for 'pluck in' cars....)
....ok, ok....more later.... - "Fundamentally, we work to create, and only incidentally do we work to eat" -(Willis Harman and John Hormann)

Welcome to the forum, glad you joined us.

Hi Alexander, welcome to the forum

I noticed your love of a Honda 4 stroke running through gears.
I run a GX35 running through a standard 9spd cassette , Ive run over 1000ks in the last 3 years, with no problems. (I'm only 10ks from work.) Its great having that range of gearing.

Hard to believe you only get 60k's to the litre with the 31cc. I worked out I get over 90kpl although that is on the flat, traveling at 50kph.

By the way, I love old scool GT's, I have a 2 stroke LTS also. Do you have any pictures up yet?

Cool. I use a 3 speed on my trike. 2nd gear needs to be spot on though or it will slip so I need to adjust that puppy before every ride.
I would love to see a pic of your creation.

Hello & welcome from Pa. Dan

I forget now but it's way vintage. It only slips because my adjustments constantly loosen up. It's only a 10 second job and as long as I check the adjustment before every ride it won't slip.
(edit)
WOAH! I'm using a 3 speed HUB you got yourself an actual gear box!
What... IS THAT?
Where did it come from?
You say "hub".
I see a derailier and a fixed sprocket.
I also see an actual gearbox by the engine.
(edit)
WAIT! That IS a hub!
It's used like a jack shaft!
Dude. We need closer shots of that. You must have needed to have added another sprocket to that hub.
(edit)
I just keep seeing more stuff!
Check out your Derailier chain tensioner!
