Major improvements in the last week. Got the bastard project running thanks to input from other kind souls on this forum. Next meeting, many beers shall be bought as thanks, provided your there that is

. It's just a shame one jet is still a tad iffy, but as per pictures below, I got her functioning and revving along quite healthily elsewhere throughout the rev range. No air leaks on the exhaust side of things, and im going to use silicone around the carbs to ensure there aren't any airleaks pre or post the carbies.
I re-bled the front caliper with a better brake bleeding kit and got a big bubble out, now the brakes have improved even more, but still it's only a shadow of what any multipot caliper can dish out. Next is to check and most likely renew the rear brake shoes, then mount up the crashbars (they are held on with good old zipties in the pic below. I guess i should start considering replacing some of the wiring out from the battery as the fuse looks a bit dicy and the wiring a bit long in the tooth. But from the checks ive done elsewhere, aside from needing to give the switchblocks a REALLY good once over, the wiring is otherwise pretty solid.
Then theres the whole pesky missalignment of the front light and indicators, i can fix that, but its not a worry as it'll take bugger all time to fix with a rubber mallet.
