Not much to choose between the two of them. Go for the one that parts are easier to obtain. I use OKO`s on my three 350 Sherpas.

EBC brake shoes are the best ones off the shelf.

File those ridges flat. On both side of the slot. This will make your clutch a lot nicer and easier to use.

Hi Halfway. Yes any later Sherpa T front wheel will fit. Even some of the earlier ones. I think they changed to the conical hub for the M 91 front wheel. I`m not sure on that one though. The bash plate was a part of the frame on these models so if yours is gone then someone has cut it out. Any welder would be able to weld a new one in there. They had either round or oval holes in them. Have a look on eBay for parts too. In Motion often has second hand parts too.

Get it started up and get the bike warm/hot. Then get a small flat blade screwdriver and just set the idle so the bike is idling okay. Then move the airscrew until you find the highest idle point. That is the correct airscrew position for your bike. Make sure it will accelerate fine with no hesitation or sluginess. This is the best way to set your airscrew. Every engine is different so tune your engine how it likes to be.

Usually you will need to take the hub out of the rim then any good engineering shop should be able to do it. Ask around in Motorcycle shops near you or look on this page for ads if you`re in England.

Try any Bultaco shop. Also Amal Carburettors in England.

Start off by just checking all the connections in the system. If it still has the standard screw terminal under the tank pull all of those out and make sure all the wire ends are clean. Maybe give the lighting coil in the mag a clean with some fine sandpaper too. Does the brake light still work?

Being tall is no reason not to ride. You can still get higher rise handlebars or buy some bar risers. The 1979 world Champion is well over 6 foot high. You can also move the footpegs back and down with some modern footpegs which makes them ride a lot better. Once you have the knack they are easy to start. They do like to be timed regularly though. Go for it!

May be try Peter at Bultaco Australia. Also ask at any English bike spares shop as almost all of the old Triumphs, BSA and all the others used Amal controls.

Hi Bultoboy. As far as I know it was on the MK 8 Pursangs which was 1975 or so. It happened because the USA government made a law which said that all road going motorcycles sold in the USA had to shift on the left and rear brake had to be on the right. The MK 7s only had right side shift.

I use 80/90 weight car hypoid gear oil in the gearbox. 550cc if just changing it or 600cc if you have had it apart. Primary side I have been using a motorcycle 10/30 weight gear oil. 250cc is just changing it or 300cc if you have had it apart. Premix I have been using Castrol TTS or Power 1 Racing they call it now with the highest octane premium petrol you can get at 50 to 1.

Just going from memory I think there are 6 drive plates and 5 driven plates. Try that and see how that works.

On that photo it looks like there is a ball bearing missing or there is one to many clutch plates in there.

Most either use the standard points or put a CDI system in them.
