BTW, my recollection is that my BMW (break my wallet) Funduro was a dry sump engine and had its oil stored in the frame, like my 1971 Triumph Bonneville did.

The BMW F650St Strada was introduced to Europe in 1993, a variant F650 (dubbed the 'Funduro') in 1994 and then to the United States in 1997.[3] The BMW F650 models were jointly designed by BMW and Aprilia, who also launched their own very similar model called the Aprilia Pegaso 650 (a 654cc single cylinder, 5 valve motorcycle).[4] The BMW version was assembled in Italy by Aprilia and these were powered by the Austrian 652cc single-cylinder, 4 valve Rotax engine.[3] It was the first BMW motorcycle with chain drive since the 1960s.[3][4] The two variant models of the F650 motorcycle had some subtle differences which determined their utility bias: the F650 'Funduro' was the more dual/multi purpose with more off-road capability due to the longer wheel base, more ground clearance and taller seat height, a higher front fairing and a larger 19inch front wheel, the F650St Strada had slightly smaller dimensions and an 18 inch front wheel. Both models used two 33 mm Mikuni carburetors.[4]

Engine   652 cc Rotax single
Top speed   F650 - 185Kmh (max rpm 8000)
F650ST Strada - 165Kmh (max rpm 7000)
Power   48hp (35kW) @ 6500rpm
Torque   39.2 lb⋅ft (53.1 N⋅m)
Transmission   5-speed, chain drive
Weight   173Kg (unladen) (dry)
191Kg (wet)

Design and technology
The F650GS had several advanced technology features for its time, with computer-controlled fuel injection,[when?] catalytic converter, a Nikasil-lined cylinder, optional ABS and an airbox designed to exploit the airflow pattern of the bike when in motion. Combined with the bike's high compression ratio and twin spark plugs (from 2004 onwards), excellent fuel economy and low emissions existed alongside high power output. The original F650 single-engine was manufactured for BMW by Austrian company Rotax while the bike was assembled by Aprilia. When the F650GS was launched,[when?] the full process was brought back in-house.

In 2000, the German motorcycle magazine Motorrad reported about a defeat device delivered within the BMW F 650 GS. BMW responded in issuing an improved injection as of 2001 and calling back the models from the previous year.[6][7]

Amongst the changes from the original F650, the engine was upgraded to a 43 mm throttle body. The fuel is stored in an under seat fuel tank,[8] and the false tank (where a conventional fuel tank would be) housed the remote oil reservoir (for the dry sump), airbox and battery. This contributed to a lower centre of gravity for improved handling.[2] The bodywork was redesigned by head BMW designer David Robb.[2]

Due to the high numbers sold, the F650GS developed a large aftermarket accessories range and a sizeable owner community. BMW also developed a large range of factory original hard luggage for the bike.

Been going through the different F650 models and it looks like the Flywheel / Rotor for the 1995 F650 is a carburettor model. So it should be straight forward converting the EFI to carburettor.

The BMW Funduro engine was also used by MV for a short time installed in one of their sport bike chassis around 1999 or 2000. I remember seeing one for sale in the shed next to the Alice's Restaurant gas station. I seem to recall that the tachometer was redlined at 9K rpm, which caught my attention. Somewhere in my many disorganized photo albums I have a couple of pictures of the bike.

48ish BHP and maybe 180 Kg dry were the numbers to shoot for, I'm amazed Mahindra couldn't replicate that in 2022. Seems to me a 2nd hand $2k Funduro/Strada would give you at least a $5k modding budget. No reason to not have a DIY Goldstar, you are mostly a tank, muffler & fenders away.

We live in a carbon fiber, 3D printer future, I'm not seeing why the "Faux-star" is slower & heavier than previous efforts with this engine. At India labor rates, even hand laid up CF parts painted to look like steel would "add lightness". Lighter = more HP, better brakes for the same components.

This ^. You have it arse about face. India are more interested in cheapness than performance. They'd do the exact opposite and make a cheap heavy steel component and paint it to look like expensive carbon fibre.

So is there a near $4000 "contact name magic" markup going on here? If we Statesiders can get the Interceptor for about $6K, the faux Goldstar should be less, that's one of the advantages of singles, less parts, cheaper to build. The 250-350 street motorcycles that used to be twins are mostly singles now. Selling a new "nice bike" at extra-premium rates competes with the used market, awash with "nice bikes" for 1/3 to 1/5th the price. The enthusiasm for the original Goldstar was about it's superior performance for its time. It would be reasonable to expect a similar "spirited" performance level today. Using clever engineering and low-cost labor would be a reasonable way to achieve this, if that was your intent. SInce it's not happening, maybe we can expect a $4500 Fauxstar in 18 months or so to move unsold inventory.

I'd have a SR400 any day.

Hmmm...27 HP, 174 Kg/384 lb. wet, 5-speed, what's not to like? Available on Craigslist from $3500, Cycle Trader From $4500 & up. They are holding value, obviously people like them.

My late father was once offered that model of Gold Star for £50. He turned it down. I think it would be worth rather more now....

Indeed, but not the insane prices people pay for a Vincent Black Shadow ...
