Its rideable-ish as the megasquirt is still on the bench although the fuelling is messed up because it has the bellmouths on in place of the original airbox

The manual tensioner turned up and is sat on the bike bench along with the bike waiting for a spare half hour to do the deed with, the 5v lm7805's have turned up to make the +5v supply to run the bluetooth adaptor etc and all the components to make the pickups are here. Im having a wobble about the pickup design as all the auto world seems to have a solid reluctor interrupting a pickup rather than spinning embedded magnets. The very best of both worlds would seem to be to cut a metal reluctor to the tooth pattern of arttu's pickup setup, but then of course how to make the reset trigger?
The only way I can come up with is to have two reluctor discs on the cam, the outer one slightly larger than the inner. On the inner disc just have one tooth to provide the reset, then the outer disc to have the triggers then one magnet/pickup on opposing sides of the reluctor to give the same output results as arttu's. Ive got a proper plastic moulded holder for the pickups and magnets with a airgap between designed to hold everything for a reluctor to spin through for this very job.
That way I wouldnt be spinning the magnets, the reluctor would just be two simple steel discs with some cutouts that I can whizz up on the rotary table and a grinder, and I could stay with the stock kawa steel baseplate mostly. To index the two plates together just a simple steel pin through the lot, the same way that kawasaki do to pin the stock reluctor indexed in place.
Ill give it a go, itll either work or not.
Running gear wise, the zx7r discs from mckdavid turned up and are good cheers dave, hope you like the dynas. Have to remake caliper bracketry (as expected). Waiting for some stainless disc fasteners to arrive after a lucky ebay snipe. Bought a new tyre too.
I got a new model z1 swingarm (for 19e, my kind of budget

) as the bandit swinger didnt look to accomodating to take the new z1 wheel. Its miles (well 26mm) too wide to go in the frame, but I think I can shave off enough from the overall width of the swingarm pivot and just about stuff it in. At least it fits the z1 wheel nicely. I still have to work out if I can get a straight chain run with a 530 or 520 chain and a offset front sprocket. Its going to be tight, but it always was with a 190 tyre going in. Now Ive bought all this crap its going in if it likes it or not mind, even if I have to stretch the frame width near the pivot like I did with my gs
Have new bearings the correct size for the wheel in their packets so that was a stroke of luck but theyre still sitting in their packets on top of the wheel waiting for get-a-round-tuit to happen.
Actual progress in the workshop, not so great. Ive been tied up with other stuff in my life which has to take priority (building a little motorbike for my lads 6th birthday was the real rush job that sucked the early hours up for a week or two

) . But Ill get to it.
