Hi all!! First time posting to this great site. I just purchased a 1960 G12 650, online. Owner said it ran perfect. Yeah, right. I managed to get it running, but when trying to put it in gear, it just chattered, as if the clutch was not engaged. I pulled the side cover and can see the pressure plate releasing from the clutch pack. Also, when just stationary, not running, I can only move the shifter from 1st to 2nd. It's jammed after that. I am a car mechanic, hot rod builder, and am unfamiliar with the workings of this transmission. What do you all think? Somehow, I get the feeling ill be diving deep into this gearbox. Thanks in advance. I am going to drink heavily in preparation for the news,yet still remain hopeful. William Seattle, Wa
Not getting gears without the engine running is not really a sign of anything. Try spinning the back wheel while clicking through the gears is a better test, if you must. (engine not running while you do this !)
Old clutches often need 'clearing' 1st thing in the morning. Pull the clutch lever in, and kick it until the clutch frees off, and spins freely. Then try starting it, and seeing if it goes cleanly into 1st gear. And goes through all the gears as you speed off down the road. Gotta get used to british bikes foibles... Have fun, hopethishelps.
Rohan, Your optimism is much appreciated. Kick it until the clutch frees off and spins freely? So, start it w clutch lever in, and then what is meant by, frees off? So this is not uncommon? What's the cause? I know the bike has sat for a while, and the chain cover was full of milky oil.
the plates inside the clutch basket stick together solid when they're cold because of the oil. pull in the lever to take the spring pressure off, then kick. all the foot force goes to the driven plates, while the driving plates are held still by engine compression
the motor will turn over and over as you kick it until eventually the clutch will suddenly come free, and you will whack your shin on something.
if it's sat for a long time the plates might be well and truly glued, and you'll have to take the pressure plate off and winkle them apart.
As soon as you try to walk the plates out you'll understand what he means by winkle. You'll have to wiggle them out side to side, top to bottom, a little at a time. Atf works good in the chain case, most seem to prefer the Ford type F fluid
When given the choice between two evils I picked the one I haven't tried before
Winklepickers, or winkle pickers, are a style of shoe or boot worn from the 1950s onward by male and female British rock and roll fans. The feature that gives both the boot and shoe their name is the very sharp and long pointed toe, reminiscent of medieval footwear and approximately the same as the long pointed toes on some women's high-fashion shoes and boots in the late 2000s.
The extremely pointed toe was called the winkle picker because in England periwinkle snails, or winkles, are a popular seaside snack which is eaten using a pin or other pointed object to extract the soft parts out of the coiled shell carefully, hence the phrase: "to winkle something out", and based on that, winklepickers became a humorous name for shoes with a very pointed tip. Other countries had other humorous names, e.g. in Norway and Sweden they were called myggjagere/myggjagare, literally "Mosquito hunter". They are still popular in the raggare and rockabilly subcultures. In some parts of the U.S. they are called "roach stompers."
i had never heard of winkle pickers.
although in america we have what we call waffle stompers
Well, I winkle picked those clutches apart and lo and behold, she freed right up. Gave them all a good cleaning and scuffing w 320 grit, filled the case w Type F and shes roaring like a two dollar whore on a trampoline. Thank you all so much. Now, onto another simple question:
The Smiths Gauge reads 32545. Since I have not ridden this bike yet, I can't know if the last digit reads in tenths or not. So does it have 3,254.5 miles, or 32,545?? Thanks in advance!!!
