You cannot run an alternator with a flattrack primary cover
Back in the day your choices were:
Trackmaster or Kosman fabricated from flat plate and two derbys welded on to clear the clutch and crank end
Kosman fabricated with two spun aluminum derbys held on by allen bolts
ACK cast primary as used by Jim Rice and Dick Mann (Ray Abrams at A&A has threatened to repo these for years...he has my spare as a sample)
Carl's Sport Shop cast primary as used by David Aldana
Smitty of Rock Island cast primary used by Mickey Green
None of these are currently available although there are a number available for Triumph 650s
So your choices are
Buy a Triumph
Try to modify a stock primary cover
Watch eBay and be prepared to spend $300-400 US
Contact Sandy Kosman regarding having one welded up

you need to switch over to Triumph 2 row or Goldstar single row or space out the cover to clear the 3 row

one of the crucial functions of a flattrack primary is to protect the crank end and clutch in case of a low side get off
the other is to provide ground clearence in high traction events (Ascot would be a good example)
One low side with that setup and you may have a bent crank

Some visual aids.









Sorry about the focus on this one, I believe it's a "Carl's Sport Shop".

On the subject of Jim Rice, I was looking at a picture of him after winning a flat track race in I think 1969 in an old Classic Bike last night. His bike had what looked like a second clutch lever on the left bar sticking up at the same angle as the clutch lever faced down. What would it have been, decompressor?

Thanks

Tom

Thanks Guys! So was it just rider preference rather than having two levers (brake and gear) for the right foot?

The 1969 season brought big changes (AHRMA thinks this happened in 1968) 750s were allowed regardless of configuration, rear wheel brakes were allowed and Trackmaster frames appeared
There were a lot of new bikes with a variety of approaches
Some guys went hydraulic, some guys even had cable operated calipers, some guys left the brakes off, some used Hbar mounted master cylinders from the CB750, some had a second clutch lever, some had a foot lever and one great even operated the pedal with his heel
Interesting times indeed

Try Mold Trends,Inc at 203.483.1420 they have been making flat track primary cases for Triumph and may also have them for BSA now.

A late reply is better than no reply, right? Anyway, back then there a few different ways to setup a rear brake on flat-trackers, since even having a rear brake was something new. I used the same setup as Rice, adding a second lever on the left handlebar to control the rear brake. I'd tried it first on my 250cc short-tracker, and it worked great, so I did it on my "big bikes". The now-common setup of having both the rear brake lever and shifter on the right foot was used by a few guys, but it hadn't been perfected yet. One thing to consider is that most of us were still running drum rear brakes, which required a much longer lever to take up slack when they began to fade. The short levers used with discs make it easier to have a brake and shifter on the right. That slack could easily be adjusted with your left thumb on a star wheel adjuster using a left handlebar lever.

Most riders just used the standard left foot brake pedal, braking only until it was time to put your left foot down. I tried that a few times at first, but "feeling" the pedal with a steel shoe on was impossible. I hope this helps.
