But is he as happy?
Is it still beastiality if ya fuck a frozen chicken??

Too slippery to get a good grip ? Likely to bite ?
You should have tried arguing with my old man, just for practise he'd argue black was white...But when it came to engineering he didn't lose many, AMIMechE covers a lot of bases....

Right. Updates.
The Gixxer shock has been sprung for the job it has at the back, and the front shocks have had a service. Sits really nice bow and 5he damping adjustment has obvious actual effect.
Gotta extend the swingarm next, and I'm thinking about flagging chain adjusters. At the minute the bike is so fucken torquey that we haven't needed to change gearing. If we ever do though, so long as we do it in 2 tooth increments and change the chain we should be all good.
Please discuss if anyone still reads this.

Why? Is it more difficult to organise than usual?
Only, if you're changing swingarm length there's presumably handling benefits involved. Why not leave yourself the provision to change swingarm length to a lesser degree in order to fine tune that?

Extend the swingarm with a non adjustable axle, make the chain adjustment on the swing arm pivot. It could be as simple as a slot and block type arrangement (which is what I'm planning on using) like the chain adjustment on a road bike. Or you could get Alan to use his engineering skills and make up an eccentric adjuster.

Our swingarm is currently too short. Turning right is next to impossible with the throttle open at all as it just unloads the front hoop and drives straight ahead. This can't be completely fixed, what witha big chunk of the bikes weight hanging out the left. But it can be improved.
The sacrifice is of course reduced direction changing speed. But it's still a short chair so better at that than a gay long chair.
Adjustment is hard to build in since with the new axle/wheel, one half of the swingarm needs to come off completely.

Well if it's too hard to change the arm. I'd go for a slotted pivot mount on the frame and inserts to suit.
The Rickman round insert is nice but for sheer bloody minded cheap arse practicality, the Colin Lyster square inserts take some beating. There's a locating strip welded to the frame front and rear of the slot, an off center hole in the insert - and you can turn each insert two ways...
i can't post pics here but if you want to see how Colin did it, PM me - I've got a Lyster frame here.

OK. But like the man says you could make the swingarm pivot adjustable, no?
In fact a cleaver bastard might make it adjustable vertically as well, there's advantages in messing with arm pivot height to change weight bias under acceleration, and if you'd like the front planted a bit better on the gas and maybe just a little drift in the back it might be worth some design hassle.

Be fucken funny if I did.
Built a work table for it this afternoon. Now we can take shit apart and still move it round.
Putting adjustment in the swingarm pivot, is only beneficial if the other two wheels are adjustable to balance everything. All we wanna do is get a number board lower than 6 after the nats. Then start again on something better.

no, its also beneficial for chain adjustment.
Ta
No, a chain worn enough to need adjusted is FUCKED.
i'm motarded
unless you change the gearing.
Forum whore
Im thinking of this idea for an invention where you get a round thing & drill a hole in the middle of it & put a shaft through the hole & you can put it under things to make them easier to move.

I'm not reinventing anything. I just figure that adjusters are not required if we have a few different chains to match sprocket sizes.
