HELP! Dual Front disc brake rebuild..

Hey guys, Can anybody offer some advice on a 1981 Z (B) Model 650. I'm working on a dual disc system up front and both the calipers have been completely dismantled for paint and restoration. I've replaced all the necessary parts and ensured the proper fit etc but I am unsure of the following things ...

Re: Cylinder 2 & 4 Not Working

Added oil to the plugs. no improvements. Got frustrated so took the carbs off the bike, dismantled and reassembled them. Started up the bike and it sounded great. Now cylinders 2 & 4 are firing again. They are not as hot as cylinder 1 & 3 but they are responding. Not checked the compression ...

Re: Cylinder 2 & 4 Not Working

Hey guys,

Have checked the compression readings on the two working cylinders and they are reading around 85 - 90 psi. Clymer manual tells me that this is low. Low meaning the beginning of a problem.

Help?! Any thoughts next?

Re: Cylinder 2 & 4 Not Working

i've cut the coil cable 5mm and have ensured a good amount of contact between both ends. I've also tested without the boot, where the spark plug is pushed directly into contact with the cable, only on cylinder 2 though.
Still shows weak spark.

Will come back to you with compression readings :)

Re: Cylinder 2 & 4 Not Working

Hey Folsoml, I've checked all the plugs, number 1 and 3 spark fine but 2 is particularly weak and number 4 is actually sparking really well. Perhaps a little too well. I've tested with the old coils and a pair of brand new coils. I read briefly about the relay system but don't know a great deal abou...

4 into 1 or 2 into 2 exhaust?

Hey guys, Just wondering if you could offer a little technical knowhow... My CB currently has a 4 into 1 exhaust which is lovely and sounds great. When I bought the bike I asked the guy why he'd made this change and he told me it was because of the sound. I've recently been thinking about changing t...

Wow, Mighost, that's exciting! This would work for replacing the wheels of a '81 z model? Thanks!

Re: New to the forum so i guess i'll post my Brat

Dude this is spot on. Absolute inspiration for my project. Well done on a fantastic build, it's all looking really tight. Curious though - Did you sandblast the engine? Also, Spoked wheels? The pictures on your photobucket show comstars, what did you do here? I'd love to spoke mine up but the only s...
