Well this 5 speed 56a is in and working ok. My effort at the Bagshot rallysprint on Saturday exposed several problems:

. Steering is too slow;
. Rear suspension is too soft;
. Diff is broken (pinion actually).

What can I do to speed up the steering?

. shorten the steering arms (is such road legal?);
. quicker steering box (currently 15 to 1);
. normally a smaller steering wheel is an option but I am already down to the smallest I have seen.

Anyone know the ratio or a 1200 (B110) or 120Y (B210) steering box?

My gearbox saga.

Probaly the easist will be to fit a steering quickener.

Looking at the picture, the weight transfer to the rear looks quite good as you have enough grip/power to lift the front wheel.

I've never heard of a steering quickener before but will investigate. There's even one for sale on ebay!

Thanks, Mark

1000's are a gokart
Can't understand needing the steering quicker

Maybe start playing with ratios in the box (having them made) or custom arms
But don't go introducing bump steer and other issues that make the car unpredictable

It's about 3.5 turns lock to lock. 2 to 2.5 would be better so I can react quicker on loose surfaces.

whats the engine in your rallye 1000? A10?
Some bloke was saying long ago that a J13
crank is a possible upgrade for stroking.

This steering quickener concept has me thinking, I now have several 3 and 4 speed gearboxes doing nothing (including a 56 option 1 4 speed). I could put one of those in the steering column, just cut down the bellhousing etc, Then I can change ratios to suit conditions and the strength in my arms. I think the steering box would would need to be at the input end.

I wouldn't have a clutch or permanently mounted gear lever, changing ratio on the move would be just silly!

Motor is A10 bored .5mm. Stroking is legal but A12 being 5 bearing is not really sensible. Now where do I find a J13 to get a crank?

Thanks, more cost. Mark

I was under impression you cant use an A12?

Also not allowed steering rack?

I am allowed to use an A12 crank, not block. But being five bearing it's out really.

I left the word "crankshaft" out last time sorry.
