there are a lot more brands in Russia than may be something not exported......ive even seen pictures of a half baked Harley copy.....more of a larger Yamaha 250.

Looks like one of the scrapyard specials from the wilds of eastern europe or the balkans pre glasnost.Its obviously seen fair use for a period ,probably until someone saw value in the motor and gearbox,and sold them on ebay.

FN used a lot of existing gun fitting threads.....for instance the 1/4" x 22 thread is from the two triggerguard screws of the 1889 Mauser rifle that FN was set up to make.All the machines and tooling were supplied by Ludwig Loewe of Berlin,who were also variously part owners ,mortgagees in possession,and finally all the machinery was repo ed in 1914 to form a fifth production facility in Berlin at DWM......then all grabbed back again in 1919,with Loewes dispossessed permanently as they were jewish ,however DWM seized the plant again in 1939,and used the FN military bike as a model for the BMW sidecar wheel drive.

Wheel and axle nuts are often odd sizes for serviceability ,and so the cheap tube spanner in the toolkit wont bust first time you get a flat tire....I find with a selection of metric,AF and W /BS tools I can fit almost anything......For instance ,the Norton laydown box has a casing nut requiring a very thinwall socket........doubtless the original tool was a tube spanner.....Period pictures of factory assemblers show stacks of tube spanners beside the bikes................obviously better quality than those in the bike toolkit.

if its truly a DC generator and regulator.....the vibrating points of the voltage regulation coil will be producing spikes read by the digital meter......So,if the battery stays charged ,and doesnt boil over,then its best to leave well alone...If its a AC system,then lights may work,but the battery will not charge,and generally boil dry ...........Also ,no system will give meaningful readings if the battery is sulfated/flat/dry.,although the lights will usually work.

The BTH magdyno is very unusual....and rare ,I expect.......The fuel line is likely spray paint hose,thiokol lined and the only fuel line Ive found to be 100% reliable with modern fuel......which is pretty close to paint thinner in chemical makeup.

I think the 69 will have a 500 twin rod and plain bearing and a one piece crank...from memory....i also think that the plain bearing setup cured the bigend failures that were common ......but I dont memory of those days is getting sketchy......You are probably best to contact someone like SRM.who are still in business.

Last place I worked was a big operation,but the owner had a radar for cash jobs,and would suddenly appear when a boxtrailer with a old  bed frame or old car bits came in the gate......A $20 note was enough to lure him out....

In the far distant past i bought a BSA Victor. 441 Scrambler.....the big end knocked out in about 5 minutes.I bodged it,and sold the bike.All I know............As for the 350s,I used to buy them at the army sales.......double pallet with 8 bikes strapped on for $300-$400.... about early 80 s,I reckon....B40GA ,they called em.....The army found them to be rubbish,and replaced them with Suzuki 400 twins,all painted green......They used to sell for about $300 for 8 strapped to a double pallet.

Out here the EPA license and compliance costs are round $100,000 a year for a small operation.  Adds on to the cost more than somewhat.........In fact,you could probably fly the stuff to India and return a lot cheaper job.

B40 was a 350 with an iron barrel and were commonly used as army bikes.......B44 had a alloy barrel ,and was a 440.....IIRC.

I d never get chroming done again.....since hexavalent salts were banned,the platers all say it doesnt last......I would get stainless rims,or just go with paint........where I had the wheels professionally lined,it seems a etch was used,which has lifted the chrome where the lining is........Fortunately,the tank wasnt done by the same guy,and the chrome is still 99%..with one little patch thats visible in sunlight.
