I would argue it's more safe than clutch shifting but to each his/her own.

Here's a very informative albeit boring video on how motorcycle transmissions work. https://www.youtube.com/watch?v=7EMIdGgsQ68

I dont have a detailed understanding of motorcycle transmissions, but my basic understanding is you are using the interval when the transmission is not under a significant load to shift between gears for both clutchless and clutched shifts.

From the video you can see the dog tooth gears engages different transmission gears to create different gear ratios. When you clutchless shift, preload the shifter and then completely close the throttle so the only rotational load on the transmission is limited to friction + combustion at zero throttle fuel-air mixture. The preload on the shifter allows the dog tooth gear to slip from the current gear position to the next gear position when the transmission in unloaded. The gear change happens fast enough that the input shaft from the clutch does not slow down enough to misaligned the dog tooth gear. Then you roll on the throttle and keep going in the new gear.

This is a similar to when you use the clutch to shift. When you pull the clutch lever, the only load on the transmission is from friction. So in the low load situation the dog tooth gears is able to slip from current gear position to the next gear position. You then start to engage the clutch to bring the engine back into the equation, balance out the rpm of the input to output shaft relative to gear ratio, and roll on the throttle to keep going in the new gear.

If you've ever hit a false neutral then tried to shift back into a gear, doing it quickly even with the clutch will result in some chatter. That's because while in false neutral the input shaft-dog tooth-output shaft have become misaligned. Also explains why while you're bike is off and in neutral, you need to roll the bike slightly to get it into first.

Maybe someone who works with motorcycle transmissions can add/correct my explanation. I'm always interested in learning more.

are you looking at used parts only?

http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=cb-1%20clip*&rt=nc&LH_ItemCondition=4&_trksid=p2045573.m1684

the international section should have 2 sets (split into 4 listings) out in ireland. You'll have to pay international shipping but it should come out to be 60-80.

If you cant find someone to trade with, ebay has a few sets for pretty cheap. Just search "cb-1 clip*" and only look at "used" items.
