Did some more shaping on the tank today until I was happy with it. Then glassed over the outside where the bog was, ground, chiselled and sanded the bog out from inside and glassed the inside. Tomorrow I will grind off the glass on the outside and get the bog shape back. Understand? I put black pen on the bog which transfered to the first layer of glass as a level marker so I know where to grind it back to.
Also worked out what might be a clever non welding method of mounting the Lockheed capliers... make a 8mm ali plate that bolts to the caliper and the lower existing brake mount and then goes down and between the wheel and the fork and has the axle pass though it pinning it in place. With a thin well fitting iron sleeve in the ali to stop any chance of the ali flogging out if it had any movement.
Seems the best answer I have come up with yet. Just got to find some plate now! Regards Gavin
Got the tank ground back yesterday and put some filler surfacer paint on it... MUCH better shape, fixed my shaping mistake from 1996... 4 hours of shaping and sanding a painting. Working out the best way to hold the thing down now. I did have a stainless strap over the tank but I am going to ditch that and make something at the front for it to slot into and maybe a peg at the back to locate it and stop it moving sideways and a rubber tie down to make it quick to take off.
Made a new front mud guard yesterday, use the cut down LC guard as a mould and took the shape off the inside of it. Got lots of finishing fun on that next. Might keep the tank strap as I like the look... but will get some holes waterjet cut into it to make it lighter. Gavin
Hiya Guy, Great to have you here. I am in Hamilton at the moment working on the bike in my fathers workshop... making good progress. Photos to follow when I get home again. I would like to come down for the 25th just to watch the racing and help in your pit if you needed anything Regards Gavin
jeez gavin hit the brakes at the hairpin and she,ll fall apart!!at least you should get a few $$ from the scrappy for the ally on your floor!! nah, she is a work of art mate,good onya!!can I have a go??catch ya later
What was weird? The story, the bike or me? I would take a blanket "yes" Gavin
PS Bike is striped down to just frame and triple clamps and I am grinding off odd bits of dead weight I don't need and fitting a new cross member at the front to mount the front of the engine off. I am going to weld on eight threaded tubes either sides of the cross members at right angles to the tubes and make four right angled engine mounting plates that bolt on. Then I can move the engine about as needed with only new plates made up. I am also moving the front of the rear shock up about 12mm to help clear the air filters.

Been working on the engine for the past week... raised the exhaust ports 1.5mm... ported the transfers a little, ported the reed blocks. Looking at boring the 28mm RD400 carbs out to 29.15mm when I get to the lathe again. RZ reed blocks are fitted with reed spacers.
Going to match the inlets ports to the pistons ports next. Will set the top end up at some stage soon and see what the head clearances are like. Fun fun fun in the sun sun sun. Regards Gavin
hi gavin racing at Hampton pretty good,got off to a slow start but eventually got a PB but still came last!!what the f**k!!my excuse is the field was full of younger and more trick stuff,the buggers had ohlins,slicks and motors worked to buggery etc.it was a class for pre 89s.my poor old elsie looked like a pensioner out there.sounds like your bike will give them a rev up tho.get her out there!!!cheers guy
Will, it's been almost 6 years since I posted here... and I have done NOTHING to the bike in that time.... I have basically finished work and I am spending half my time looking after my elderly mother , moved workshops, had health issues,... you know "life" that gets in the way of doing up old bikes.... but I am back baby!!!! I have time on my hands (but bugger all money) so I intend to get the bike out again and move it to my workshop and get some shit DONE on the Moto Con! Not 28 years any more but 34 four years working on and off on the same bike.... I will still build it to Post classic race spec but I really can't see myself racing it. I will either just build it and look at it, do a few track days if I can get it passed the powers that be or maybe even lend it to someone else to race?... we will see what happens....
