Topic: advice on rebuild: cyclex 'git kit' #2, 17" wheels, best suspension????

Its a bit tough to tell from your pic but I am wondering if you actually have a GL master cylinder?  They typically have an alloy base with with a round plastic resevoir.  The resevoir in your pics appears be alloy and not as large as the ones typically used in dual disc applications.  Find one that is correctly sized for the dual discs if yours is indeed not correct.  Regardless, you will want to rebuild the master cylinder and calipers before putting them in to use.   You are making a braking "upgrade" with 30 year old parts with an unknown service history so get the pieces, disassemble, inspect and rebuild.  Every GL caliper I have opened up (probably about 10) has had significant amounts of rust on the pistons so be prepared to replace these as well.  I have also found that bolts holding the caliper halves together can be next to impossible to remove on some of the calipers I have worked on.  Use some heat and penetrant.  Good luck.

Hey nice Bike man,

If mine looks half as good as that, when I'm done, I'll be stoked.

You mentioned you are split between the cycle X and carpy yoshi style pipes.

I am personally leaning towards the carpy exhaust, cause IMO, it sounds better.

and Carpy's

What do you Think?

   i think a 4-2-1 design of the cyclex pipe will give you better performance throughout your rpm range, i think the yosh style pipe is more for upper rpm performance.
  carpys pipe does sound better but the cyclex pipe comes with a mac can on it, throw that thing in the trash and put on somthing better and i think it will be an all around better set up

I actually got some bigbrakes from fishhead here on the forum. they're nissin's like on cbr's with an adjustable mc. so I'm set, but yeah that was the wrong mc and those calipers were the wrong year as well.

just an update:

thanks for the advice all! I decide against the git kit. it's been a lil rough lately with work being sporadic. I may paint the CBR and sell it for dough to buy parts for the CB, but I don't feel super rich anymore. and besides the bike is really fast as it is, it just needs to handle and stop better. so it will be a stock engine rebuild. I'll put the $ elsewhere. the opposite of a sleeper.

I am finally taking the engine overhaul class at CCSF. I just got the engine out of the frame last night and will be cracking it open on tuesday. this is the 1st time it has been out of the frame since it was built in 1971! the previous owner bought it new and never did anything except change the pipes and let it rust and rot away for close to 40 yrs. antsy to see what it will look like inside.

I'll post a topic in the project section when I have something to show you guys. wish me luck!
