    OKI MPS-200 replacement

    Hiya all, first of all, sorry for asking a question related to a CB650, not 750 - but as far as I understand, it's the same ignition, so I hope it's okay for this one. So, I'm currently restoring that bike, and I've encountered the "runny potty" problem of the igniters. While there are...

    1972 Honda CB750

    I have a 1972 Honda CB750. Had it for about 6 years. Never changed the battery, and the bike has always run well and is well maintained. I never let the bike sit longer than two weeks, and if I do, I keep it on a tender. It has a Yuasa AGM battery in it now. Over the past several days, Ive...

    Hello, I've always loved these bikes and finally found a 1975 cb750 I'm working to get running by summer. I will probably be looking on here a fair bit the next few months trying to figure this thing out. The bike looks amazing and had been garage stored since the mid 80s. My first problem is...

    Oil Lines

    I am rebuilding my 1970 CB-750 engine and need 2 new oil lines. I can get the oil hose. But I need the steel Ferrules to attach the hose to the fittings. I have found some brass ones. But they are light. And I am sure that they will corrode.

    1974 CB750k - Carburetors adjustment/balancing

    I’ve watched five or six YouTube videos on balancing carburetors for a CB750. I purchased some balancing gauges from Amazon (set of 4 gauges). “You have to learn somehow”. It seems to be straightforward with using the adjustment screw to balance each carburetor. Is this going to be a big...

    Anybody know what this wire does? All lights work fine and clutch works perfectly. The wire is still here but P.O. must have broken the connection in the handle. Does this need to be fixed ?

    CB750K SOHC fuel cap seal

    I didn't see any posts on this so, I figured I'ld share. I needed to put a new seal on my 1976 fuel cap since repainting the fuel tank. There are 2 types used on these bikes; one with a #3 phillips screw (later models?) & ones that are riveted. After removing all the cracked pieces of the old...

    Different head gasket for 1970 cb750

    I have been redoing the motor on my 1970 Honda CB 750. I’m just noticing the head gasket is a little bit different and not sure if I should be using a different one? There is one hall on the front part of their head gasket but no hole there I think it would be OK but I am not sure. I will send a...

    Hello, I have been trying to remove the pin holding the kick starter's mechanism for a while now, but without any success. Have tried using pliers and using a heat gun but without any luck. I have already read that it is better to avoid touching it as it can be complicated to put the spring...

    Rickman Honda

    I have a chance at a Rickman kit for a 1974 Honda 750. The kit might be for sale once I know the exact condition and the completeness of the parts. Just putting this out there to see if there is any interest. A Rickman build, a proper one, is a pricy project. I'd like to flip it to fund other...

    17 inch rear wheel

    The 1977 model has a hard to find 17 inch rear wheel. Will an 18 slide in without modification? The stock 17 is looking pretty good, ready for powdercoating but I may want to go higher end as the bike is in great restoerable shape.
