Australian Streamliner Bike Build

You certainly have a way with words Sparky.
It's not that bad is it?

just amazed at what various builders are willing to study, attempt, learn and DO---I am in AWE Sir!!

Jon, I spent the morning reading your build thread- great work, and a lot of great tech info!

[Jon]

Thanks Guys.
Your builds are both on my daily read list, I'm learning a lot from both of you and a many others from this site, both from the help I'm given so readily and from what people post on their builds or in response to there's questions.

Some seriously talented people on this site.

Cheers

Redoing a few things to get some room back from the underdrive.
Sketched up a new swingarm in Solidworks.
My tyre is 23" so started with a 27" tyre (2" of growth on the radius) and allowed 1" of clearance there with the chain adjusters right forward.



I'll fab it up from 5mm (0.2"), it'll be a little heavy but shouldn't flex.
Simpler than trying to go 4 link, there's no crossbar between the tyre and the underdrive unit.
Motor is now only 4" further forward rather than the 8" the underdrive takes up.
Pivots are concentric with the output shaft to help keep the chain tension even.

Cheers

You live near any pond or lake?  The news says they caught a 19-foot long python in a shop down there and turned it loose in "a nearby wetland."  Look inside your streamliner real good before you climb in.

He has more chance of his son trying to sneak into the liner then a python....

Patience, perseverance and a little bit of margarine...I recon i could fit.

No ponds around my place Bo, it was a decent size python for around this area though.

I think he's dreaming Grumm.....

After a bit of to-ing and fro-ng on the underdrive units I think we're going with B&J Pro Sportsmans.
By going with pre-made units we get more ratio choices and more chance of getting a spare if things break.
The Pro Sportsmans are rated at 1500hp and lets Greg go to one end of the ratios at 1.22:1 reduction and me to the other at 1.566:1.

The Pro Sportsman needs about 250psi to select and hold direct, a loss of pressure has the unit select low but it freewheels on over-run so isn't going to lock the back wheel (hopefully).
The input and output shafts are both 16 spline 1-3/8", will get some wide slide on splined collars and weld them into sprockets, lateral location will just be spacers between the collar and shaft shoulder on the inboard side and collar and support bearing on the outboard side.

With the swingarm going out to the frame and input and output shafts cut level with the end of the outboard bearing there should be just enough room to remove the outboard bearing support plate and change sprockets.

Swingarm turned out like the sketches:

First time I've used Waterjet cut parts, very nice to work with.

Due to a bit of scope creep I'm making some new front suspension components and going to stretch the main frame 500mm (~18"), yes you all told me  .

Upright and lower control arm.

B&Js are ordered, hopefully getting shipped in a couple of weeks.
Side plates for outboard bearings on B&Js (Greg's and mine) are getting Waterjet cut and will need a minimal machining to counterbore bolt heads, helicoil threads and machine bearing recesses.

Two out of three ain't bad, perseverance he has, margarine he can buy....

Fuel and water tanks are also getting Wayerjet cut:


30L (8 US gallons, whats this wet and dry gallon thing) in the front compartment.
35L (9.25 US gallons) of ice water in the back.
Bilge pump in the ice water tank on the left hand side for the intercooler.
Engine water heat exchanger (oil cooler core) is behind the green panel on the right rear.
Water from the intercooler return dumps on top of the engine heat exchanger to get good flow around it and heat transfer.
Two holes in the top for putting ice in as the 11lb fire extinguisher bottle tube is an effective sideways baffle.

This bolts straight to the back of my rollcage and down onto the side rails.
Mainly to give it the maximum crash protection.
I know this will make it harder to cut the top off but that's secondary to having me and the fuel tank both still in one piece if when I go a$$-up,
All the hoses etc come out the top so it can all come out easily from the top to get deeper into the bike.
A removable diagonal x brace goes the full length of the engine compartment.
