The new cam chain tensioner spring for the B12 from Suzuki works fine in powerscreen and 1100 slabby engines, and thus probably all the 1127 engines.

Oh, probably not then. I still want to keep the front and rear ends on it at present.

What for?

I want to put my bike back to 80s spec

If you don't use the stock swingarm i'd be interested in buying it

Seemed like an eb@y bargain to me. Especially seeing its got an NWS swingarm

As Clive states, early Mag 2s had the battery in the seat. They then progressed to having a removable battery box with rails that slides over the ends of the frame rails and was clamped in place. Finally, from the mid to late 80s the battery box was integrated into the frame, as shown in Clive's pic. I think earlier Mag 1s, the frames of which are very similar, had a wider variety of seats and battery positions though. There are a few pics here of my mag 2, which has the later improved battery box and uses stock bodywork.

Powerscreens have BST34 tintops, the most compact of the carbs used as OEM on oilcooled bikes. They're titchy compared to e.g. the bloody great BST38s used on some 750s. My bike had BST34s when I got it and to get RSs on meant moving the throttle bracket to between 3 and 4. Otherwise they fouled the frame spar.

MH Racing will re-build older WP stuff.

You can do a cable choke conversion on RS carbs. Parts are listed in the schematic diagram supplied with RSs (easy to find online as a pdf). I got all the bits needed from Allens.

I think you are right here. Many of the o'rings are shared between different sized BST carbs but there are also probably one or two differences so including an extra o'ring would mean the same kit is suitable for a much wider range of bikes.

If you take the Yoshi can to bits, gut it, then put it back together, it then won't sound so tinny

Does the bike in the picture above have adjustable yokes/headstock? I'm puzzled as to why the forks aren't parallel to the headstock?

The YTS that designed the tank ensured they held the same amount in gallons, it's just the US gallons are smaller than proper gallons. Probably
