81cb750f

I would check timing. Do a static timing check. Also, further to what dirtdigger said, are the wires going to the right plugs? the wires...

I don't have much experience with the SOHC 750 carbs so just a shot in the dark here. Are those the stock jets? Seem rather large. My 81...

There are three adjustments for the clutch. One at the lever to fine tune the amount of play and another at the other end of the cable...

I have an 81 CB750F and have owned it since 1986. About 35 years ago, give or take, I had my local Honda shop install a Barnett clutch...

hmm. how does it run with throttle half open? If still not good then all i can suggest is timing, valves, both of which I'm sure you've...

I have a stock 81 CB750F. Currently the pilots are 2 turns out (full turns, not half turns). Rather than use the tedious and time...

yes, good point, agree, cam chain guides and tensioners likely need replacing. I just replaced mine actually. When they are old, cracks...

Wow, you've had yours longer than me. I bought mine in 86 and still have it. Does the engine need much rebuilding? 40,000 miles isn't...

Wow, they look beautiful. Your paint and decals look in better condition than my 81. The re-painted and re-decaled 79 tank looks...

I've never used pod filters but have heard that they can result in a lot of grief in getting the bike to run properly. I would try...

Ya, totally agree, only for high compression engines. And also better to have some in the bike when storing over winter. King &...

Hi neighbour :) I'm next door in Langley actually. Anyways, quick question. What kind of gas (octane rating) are you using? If your...

You definitely have an 81. The side covers, rear seat wing, etc match mine exactly. I echo previous comments. I've had success with...

I was just browsing through some older threads, saw yours, and wondering if you solved this. Your header looks the same as mine which is...

brettp: wondering if you solved this or whether its a problem at all. I've owned an 81 cb750f for a long time and it has had a rattling...

boots seem fine. sprayed water on them at idle and above idle with no change to engine speed. will have to look elsewhere I guess. maybe...

I'll check the boots. Don't think clutch is slipping. I can still launch the bike fairly hard from standstill without slippage.

Forgot to mention, valve clearances have just been checked as well and are all within spec. But a lean condition, ya, could be. Any...

I have an 81CB750F and have owned it since 1986. I have never encountered the following until recently. When cruising at about 5,000...

I was just looking through some old posts on pilot screws and came upon your stream. My bike started making the occasional odd surge...

Thanks. Do you think it needs to be formulated for wet clutch? or maybe thats just a marketing gimmick?

Has anyone tried using synthetic oil in their bike? I was recently advised not to as these bikes weren't designed for synthetic oil use...
