Well it's almost finished now. It took longer than I had hoped. But it's running now and approved by the customs- and traffic department. Got my license plate yesterday. So made the first serious run today. Just one minor problem, the drive shaft of the tacho got stuck in the alloy adapter and broke. Fortunately it seems that only the tab broke of the shaft and all the peaces seems to got out. To little clearance I presume, because I did not used a gasket. But all together the bike runs fine, started with one kick and the gear switch is almost noiseless (compared to the heavy cracking noise of my Bonnie to the first gear). I installed a Wassell electronic ignition set. Turned out a piece of cake and the static adjustment of the ignitions seems almost perfect, but I will use a strobe eventually.
I put a dual carb cylinder head on this Thunderbolt, just because I like the sight of it. The frame has been modified, so it meets the specifications of the 1969 - 1970 bike.
I think I posted this before back in the days of 'webshots' so photo long gone now! This is my BSA Firebird 650 with SRM end fed crank & 750 conversion, owned since 1981. Bought in Shepton Mallet as a Lightning as the seller hadn't looked at the frame and engine numbers and these export models were not as well known then in the UK. He said it 'used to have some curly pipes' which he had taken off and replaced with standard UK exhausts. I got the complete exhaust and front mudguard and stays etc from the late Ted Bloomfield at MCS. At that time he had piles of them, all new and in original BSA wrappings. Not long after that he was still making up complete Triumph 500s from spares in Norfolk. I was allowed to browse through his Leytonstone stock room looking for bits (taking care not to step on his Yorkshire Terrier). I think it's a West Coast version originally as, when I bought it, it had a 17 tooth gearbox sprocket and revved out at 70mph in top!
Here are some pictures taken of my Rob North at the BSA International Rally here in Norway in August.
The bike is ready for the many thight turns in Trollstigen, this is taken about halfway.
A couple of shots taken at the campsite.
The bike is built around a replica frame, made here in Norway by a mate, he also made the tank and the oiltank, the rest is done by myself. Its a full race 1000cc engine, mostely built with parts from P&M, I am also running a belt drive and a dry clutch, the gerabox is a 5 speed close ratio conversion of a triumph 5 speed box. The bike is fast and loud!!!!

I had one like that ..parted together out of stray bits...46 cases..500 top end.....51 plunger frame...50 gearbox...dunno what kind of cams I had to start with...but ended up with sorta like yard tractor power.....ok but not something you look forward to then I got some "flat track "? cams off eBay...welded up about 1/8 in higher and about 1/4in flat on top... (technical I know... but after the install of those...the thing went really well..rev right off the end...leave all the cars for dead at the lights... was real easy for starting...and once I replaced all the gearbox springs...it worked real nice
