see im not sure thats completly true. from all the research ive done since this post, the motor it self should mount right into my 81 frame. now i could be wrong but i wont know until i rip out this pos dohc motor and fit my 72' motor in the frame.

ok guys, so to start, im very mechanically inclined, ih am a proficient welder and im not afraid to use a sawzall to make it it fit! my question is, will a sohc motor fit in my 81' frame? i know i will need to fab up an oil bag, lines, redo my electrical, an so on and so forth! i really just...

so after some trial and error i finally figured it out. havent been on a long enough stretch of road to really open it up but so far, so good. messed with the jetting, adjusted my "baffles" added more air, less fuel and it purrs like a pissed off lion! so to whoever says that you cant run pods...

i completely understand what you are saying but I know I can get it to run a little bit better than what it is now. you and I both know that these cv carbs are a complete PITA! if money was no option then I would have a nice set of cycle x carbs but seeing that I don't have that kind of money...

So I have been tinkering with my carbs for the last couple days and I can't seem to get them right. I know I will never get them perfect but I need to get them to lean out and stop back firing throught the exhaust. The bike is a 1981 cb750k, running CV carbs, 4 into 4 exhaust that goes back just...

not sure if this is the right place to post this but its the best I could find. I'm looking to mount a mini speedo somewhere on my bobber. having some issues finding any good ideas. I do NOT want to mount it on the bars!!!! thinking about making a mount on the fork tube and mounting it to the...

bruh! when it comes to a battery, don't go cheap, I've been there, money is tight, and you really want to make progress or actually ride... but don't cheap out on your battery!!! yes this battery would probably work, but do you really want to take the chance of being stranded on the road until...

trying to post a pic of my bike, hope this works. lol

amc49, could you explain the process, what number am I dividing by, I believe they are stock tore sizes. I'm almost positive the front is a 19" comstar? ive been trying to post pics of my ride but I cant seem to figure that out. but ill keep trying.

can anyone tell me, a for sure answer on what the speedometer ratio is for a 1981 cb750k. ive looked everywhere but I can not seem to find a definite answer. thanks in advance

So since tax time is here and I'm looking to finish my 81 cb750 bobber project I'm down to one last big purchase. I need a nice exhaust that isn't going to break the bank. Anybody have any suggestions. Been leaning toward the cycle x 4-2-1 race system but I'm having trouble finding any other...

I didn't know. I was searching craigslist and seen a set and was curious if they would fit. Thanks for answering my question though. I found a set of 750 carbs for a good price just working on tuning em in now

Sorry, fat fingers. I meant will carbs from an 82 cb650 fit my 81 cb750?

Quick question, will carbs from an 82 cb750 fit my 81 cb750? I don't think they will but I figured I have to ask.

So I have seen a few guys on other sites building 4-1 intake manifolds for their cb 750s. I can't seem to find what kind of carb they are using. I'm thinking it would be a fun project to try it and see what happens. Anybody have any suggestions?

I have all new rebuild kits and a jet kit for em. I have cut off open exhaust that's gunna get some washers in em for some back pressure. even when I had my stock set on it ran horrible. I don't mind fiddling with the Jets and needle settings. I'm also running pod filters on em too. I just need...

Thanks man. I just looked at the keihin CR carbs and those look nice as hell. Problem is I don't have that kind of money to drop on carbs right now. Might have to fiddle around with a set of stock carbs til I can afford those. But other than that are you sure I can use cb900 carbs. I'm just...

Ok. This is my first post here and from what I've read so far everybody seems really helpful. I own a custom 81 cb750k bobber that I've been building for the past 2 years. I'm finally down to just a few more parts to buy and paint it but I'm encountering my biggest issue yet, carbs! My carbs...
