Ok so I'm starting a build thread and here it goes..I bought a 1975 CB750 in July 2010 for $400 did not run, was bought with intentions of building a cafe racer, so far I have completely rebuilt the carbs, bored the cylinders, done some head work, and have a lot of stuff waiting for a little nicer weather, i hope you enjoy(keep in mind this is my first build)
Bought her in this condition...not too bad 8)
Doin some head work, cleaning carbon deposits and lapping valves
Thanks $50 Mod Thread
Carbs a little gunked up and dirty? Clean them up!
painting of the motor so far sorry for the low quality pics, motor is going to be black and silver
feedback and comments are always enjoyed, thanks for looking!
great work on the carbs and motor. if the rest of the bike turns out that way you're going to have one very slick bike. keep up the good work and keep the pics comin
thanks so much...my goal is to have a really clean lookin bike so im taking my time with it...there def arent many cafe racers on the streets around here so i want people to question it and be impressed when im done..pics will be updated as i get more work done
Same here... I have yet to see a cafe style bike in my town. So its going to be cool ripping through town on it cuz I know I will turn heads. I can't wait to see more pics
where you from and more pics will come soon theres a good amount of snow outside so its tough to get out there and work on it for more than 15 min at a time without my hands going numb
so i got my clubmans in yesterday (from Dime City Cycles) and waiting on some ignition stuff from cb750 supply(that place takes so long to ship) just looking for a on/off switch w electric start button cant seem to find one that i really like...any suggestions i wanna go for a newer look
so i hit a snag tonight..trying to split the cases and i cant get the 5 screws out for the countershaft bearing holder and the other piece on how to remove both pieces..anyone have some suggestions
i tried using my impact driver screws wont budge im afraid ill strip them if i keep hammering at it but i wanna get the positive stopper out of the way first just dont know how to get it off
have you tried heating and cooling them? i know it will expand when heated and will shrink when cooled may be just enough to get them loose with the impact driver (carefully)
I have never had trouble with the positive stopper but the counter shaft holder screws can be a major pain in the ass. I would recommend letting them sock in PB blaster over night, keep spraying them and also try some heat. When you get ready to try and remove them, use a screw bit and a wrench (make sure to get a bit that really fits snug)
$9 at Harbor Freight. That way you can put it in a socket/ratchet and apply even downward force as you try to extract the bolt/screws.
If you look closely at the screws holding the countershaft bearing they have been punched to keep the bolts from working loose. I have had success using a dremmel to carefully grind out the section of the screw head before trying to remove.
If all else fails I have drilled out the screw top and removed the rest of the bolt with vise grips many times.
