So I have a bike geometry q for all you knowledgeable kernts out there....

Longbike, while superior in nearly every aspect of performance/load carrying ability/awesome etc, has a handling issue in that you simply cannot let go of the bars in an upright position without the fuckers darting to one side and making you poo your pants a little bit. It is actually not enough of a problem to make me not ride it, but it would be good too see if this can be improved.

Having pondered the issue during the many miles I have now covered on this beast I have decide that it is either about the angle of the steering pivot line or the distance between the steering pivot line and the front axle. So what I want to know is this; which is the most likely culprit so I can make this better?

Thanks in advance.

I'd say the top one would be best, looks like it has equal(ish) length primaries + it is a 4 into 1 which will probably be peakier at the expense of low down torque. Also cast manifolds are poos cos I say so.

Fucking sweet, smooth riding perfection. The only problem now is the single gear - I max it out everywhere now. I just need to find that internal geared hub from somewhere.

Yea seems too, I modded it a bit so it can pivot freely/keep the spring tension etc, the proof will be the performance on the way to work tomorrow...

So trackday has been and gone with the car mostly intact..

I had a big off at the hairpin, was doing an awesome full lock drift then next thing I know all this dirt and shit is blowing into my face through the window. No damage, but one of the rear tyres now has a clump of grass jammed between it and the rim

In the afternoon I did 7 laps hard out before the pedal went to the floor and I thought it best to pull in for a while. Not bad for a 30 year old car..

Also my brake reservoir cracked and pissed fluid everywhere, have to find another out of something else as these are not available anymore, apparently BMW 540/740 ones can be modded to fit - anyone got one?

The seat was pretty good, I semi covered it in camping roll the night before;

Rough but semi effective.

Thanks to Dodgysam ( ) longbike now has high tech chain tension

The chain jumped and jammed on the way home from work on Friday, the tensioners arrived on Saturday...

Ah did you see me give it a wee bit?

Track day on Saturday so I thought I would actually try to finish my seat, this is today's effort;

It is really quite comfy and my helmet fits too...

Will cut belt holes etc tonight hopefully then find something to line them with. Then I need to find some padding, probably foam held down with duct tape for max rang spec.

Yea, was just picking it up after getting a wheel alignment done post epic suspension improvements, is minty mint now.

Traffic is totally shit in that car, until you hit a clear spot then it is bazookas...

someone in LNI buy this and be like me

When I was 13 I had a chrome one of these

Will be sending tensioners this week...I hope ur prepared.

Do I need to break out the vas?

So longbike has back brakes now which is a good thing.

I rode it to work today and gave many, many of the denizens of Christchurch a chance to think to themselves 'What the fuck?' and ponder on the meaning of such a remarkable sight.

And if anybody is interested I have a whole lot of non leading link ct90 bits, 2 frames, 1 98% complete engine etc. Will be flicking that shit on once this is all go. probly.

Todays efforts;

Exhaust is just sitting there, was a brand new item that I got for $1 off TM. Probly going to do a serious rerout of that tho.

Random bike light that I may use if I can fit the right bulb in, really need a 5" teardrop for the original light.

Now need to wire it up, fuck I am dumb about electrickery/end of project

Should be bolt in....? and I have a spare engine now.....

I have considered the possibility.

So just picked this engine up, CT110 with CDI $60 off TM, looks pretty sweet actually.

Side cover has been removed roughly and the neutral switch is broke, but *apparently* all that is actually wrong with it is the CDI unit has a tab broken off. I can see that this is so, so fingers crossed. Looks pretty genuine otherwise, has the carb and everything

I have just put a new chain on which has vastly improved the chain jumping issue, still need extra tensioning probably.

Waiting for rain so it will rust sooner.

yea I have another ct90 engine to pick up tomorrow, if the chain jumping issue was sorted I would probably do it.

I have a chain tensioner/slack reducer lying round in the garage if you'd like it.

Would reduce the likelyhood of the chain jumping off the rear chainring everytime you hit a bump/pothole.

Be up for that, has happened already but I assumed it was the two extremely secondhand chain I have used. let me know how much.

just bought that motor, $60 too good to pass it up.

Is out of the box cable length likely to be an issue for shifter positioning? - in saying that - how to the postie bikes shift gears? aren't they a throttle/grip selector?

You can always join the cables, but I think there might be enough excess on replacement cables to cope maybe.

I bailed up the postman yesterday and checked out his bike, it looks like a standard cable going to a twist grip shifter. It will never be a performance machine so a huge range isnt an issue, therefore postie hub would be perfect. I don't like derailleurs much anyway.

needs some sweet meshy top on it, and strop hooks. hah.

This will be achieved today.

If any peeps have one of those sweet old aluminium mudguards I want them, also a sprung leather saddle of some variety. Will pay money probably.
