Been Around the Block
so a little back story first ..... my grandfather runs an auction yard and there is no telling what will come in there to be sold, so this morning my grandmother calls me and says..Come up here and look at this honda bike that came in here to be sold tonite ,it looks old. So i agree, In my head im thinking "this thing is going to be a freaking basket case that some jackass was messing with and couldnt get it to run." I go up there and Ill be damn if it wasnt a 1975 cb750 that is basically completely unmolested minus the PO taking off the airbox . It had several people standing around it, doing the usual twisting of the throttle,flicking of the switches and pressing of the buttons. So I go over to it throw a leg over it give it a few kicks and it has good compression, I get the key ,turn it on and surprise the battery is dead (actually i kinda expected that)So i get the jump box ,hook it up ,turn on the fuel,choke it a little, gave it 4 kicks and it fired , 3 more kicks and it fired up and ran fairly decent despite missing the airbox. I immediately pull my grand father to the side ,he calls the owner and $800 dollars later ,im the new owner. So I hauled it home,and go over it a little more, and the front caliper are seizing a bit , battery is shot ,carbs will need a lil TLC, but all in all its in great shape.

Lucky you, man, that thing is awesome and for a good price too. Not particularly a fan of the seat but different strokes. Any plans to modify it?
 
That is a REALLY nice find man! I wish my 75 were that nice when I found it.
 
yeah its a full kerker system and yeah that seat has to go ! im thinking tracker style and maybe clipons or clubmans , nothing to dramatic ,its in just to good of shape to just tear it completely apart like im doing my cb400t
 
Awesome find buddy. Do yourself a favor and get Mark Paris' "My CB750 Book". It is hands down the worlds greatest supplement to the shop manual for these bikes. I just did a full rebuild on a 74 using the book as a guide. He's been working on these bikes since they came out and has info only gained from such experience. I'm putting the finishing touches on mine and hope to have as my main squeeze for the spring. I may even get around to actually posting a damn build thread. Haha!
 
Thanks guys , i was so freaking amazed at how nice it was ! I put it on the lift last nite and started in on the caliper ,pads are in good shape ,separated the caliper and used the air to remove the piston ,some very minor piting here and there ,i 3m'ed it and polished it ,cleaned the caliper halves really good inside and out ,and reasembled . i pulled the brake perch and it was really gummed up , soooo disassembled and throughly cleaned it and its currently laying in the parts washer. Cant decide if i want to flush the factory lines or just do a braided line,if i flush the factory lines ,I can retain the brake pressure switch ,where as if i do a braided line Ive got to do something about the switch or activating the brake light . What do you guys think? Also ordered a battery today ,so Ill be able to diagnose any electrical problems more easily then . Also djelliott where can you get that book?
 
You can run the brake switch with braided lines. Not sure how the first gen's run the switch, but at most you just need an inline switch to activate the light. vintagecb750.com is your go to source for any parts. They've got a metric butt-ton of stuff for the first gen bikes, and their prices are very nice too.
 
well the pressure switch on it is screwed in the back of a splitter block, that is half way between the perch and the caliper. so no way to move that one . but jew is right ,i had forgot about getting a pressure switch that goes on near a banjo bolt, i've seen several harleys running them . just looked at that site as well thanks for the heads up guys!
