Not joking, I have. Just a glorified Lister engine mind but it still counts.

Oh, and a train... it was a very small train on the local peat moss but it was a train all the same.

The first 500 twins didn't have folding pegs. Mate raced one at Brands & managed to crash on two consecutive laps at Druids by digging the right peg into the tarmac.

I passed my test on one of those, borrowed from a mate because my Honda CB250 wouldn't start. I progressed to a T500, which also had a kickstart on the left.

I also had a CZ250 which had a gear lever which doubled as a kickstart. You had to push it inwards and then swing the lever upwards, kick it to start and then swing it back to its gear lever position. Try doing that when you've stalled at a set of traffic lights.

My GS750 has a kickstart and an electric start. The kickstart fouls the modified rearsets so I've removed it, by the mid 70s Japanese starter motors were pretty reliable, I think kickstarts were only fitted for those who were stuck in a time warp back then and didn't trust these new fangled electrical contraptions. If you have any experience of the "electrically assisted starting" fitted to Norton Commandos you can understand their scepticism

I remember the CZ 250 and 175 well. Farm implements were better appointed.

On my R90S the kickstart was on the left and operated at 90 degrees from a normal kickstart. Best have it on the stand for that trick.

Jawa 350s not only had the gear lever/kickstart/clutch jobbie, but had an extra neutral for coasting between 3rd and 4th.

The only conclusion I can come to is that fasteners made from cheesium improve with age.

The screw heads were fine- it's just you were using the wrong screwdrivers. Japanese bikes up to the early 80's used Japanese Industry Screws (JIS) that were cross heads, but they were easily chewed up by using a Phillips cross head screwdriver in them.

Whilst my mates were knackering screwheads to convert the "cheese headed screws" to Allen bolts, they would not believe that the proper screwdriver would have saved them time, money and a lot of swearing. Never chewed a head on a screw once I bought my first three JIS screwdrivers.

Well not 6th The gears go all the way around infinitely. 1-N-2-3-1-N-2-3- etc.

Or at least, the ones I rode for Domino's in about 2000 could. Dunno if they're supposed to.

Mr. Dazzle wrote: Wed Dec 30, 2020 9:55 pm If it makes you feel better - Phillips heads (and probably JIS heads) are specifically designed to round off

They're a really old design, from back when 'they' first started using automatic kit to build stuff. The Phillips head is designed to slip above a certain torque so you don't break the bolt. It comes from a time when machine control wasn't that good.

Torx heads on the other hand are much newer and come from a time when machine control was much better (i.e. computerised). In that case you want a bolt head that can transmit a lot of torque without slipping so you can do them up accurately with robots and also use smaller bolts.

Going to the point about screws being crap on old bikes, IME all of the air cooled Japanese engines are made of pretty poor metal, the threads strip quite easily, whether they were this bad new I don't know, it could just be a series of ham fisted idiots working on them.

The 250 and 350 LCs were a step up in quality compared to other Japanese bikes of the time, the wiring is better quality and the bikes are better out together. The FZ750 was another big jump forward, both in design and build quality, Honda didn't catch up until the CBR600, Suzuki even later with the SRAD GSXR750, and I lost interest in modern bikes before Kawasaki built a bike with an inclined engine.

ftf me

You had a it easy...the Bonnie has rearsets, so the RHS footpeg is in the swing of the kicker. You have to fold it up to be able to kick the bike.

If the peg drops half way down mid kick - which it is wont to do - it scrapes all the way along the side of your leg as you complete the swing.
