If it isn't the shift shaft seal, remove the front sprocket cover and see if the chain oiler needs to be shut off. There is a rubber seal on the oiler if you remove the oiler bolt that sometimes fails and needs to be replaced, which is unfortunately not available any longer. Some have replaced it with multiple orings, some have plugged the outlet hole with silicone, some have fashioned a custom bolt to replace the oiler. Honda discontinued the oiler on the K6 and F1.Still alive and kicking.
Can't say the same about old 75 750F. Was sitting between my two brothers Harleys at a bike meet last week and saw I was dripping oil.
Nervous because it was surrounded by dripping Harleys?
I hope it's shift lever seal or gearbox gasket.
FIRST leak EVER in the 50 years I've owned it.
Stay safe![]()
I'm all in again!August is here, CB riders.
The riding season is in full swing, the miles are adding up, and your bike has probably made its opinion known by now.
Is your CB running better than ever? Did a long ride expose a problem that needs attention? Or is that unfinished project still waiting patiently in the garage?
To keep the season rolling, we’re kicking off our August VintageCB750.com Giveaway.
Post in this thread anytime from now until August 31st, 2026, and you’ll be entered to win a $50 VintageCB750.com gift card good for anything on the site.
Tell us one of these: What CB are you riding this summer? What has been your best ride so far? What is the next job your bike needs?
We want to see the riders, road trips, finished builds, half-finished builds, garage photos, repair victories, stubborn problems, and the bikes still putting up a fight.
For more than 15 years, VintageCB750.com has helped riders keep classic Honda CB motorcycles on the road with the parts, tools, and support these bikes deserve.
From carburetor rebuild kits and electrical parts to gaskets, cables, rubber parts, hardware, and those tiny pieces that somehow hold up an entire project, we know the drill.
And when things get strange, we still have a real CB-savvy mechanic on staff who can help.
We’re also giving you 10% off your next order.
Use code CB750.com at checkout.
One use per customer. Perfect for late-summer tune-ups, roadside repair discoveries, carb work, brake jobs, electrical fixes, oil leaks, worn cables, and all the parts your CB has been reminding you to order.
Drop a comment below to enter the August Giveaway. Grab your discount. Keep your CB on the road while the riding weather is still here.
Here’s to warm roads, clean carbs, strong sparks, and plenty more miles before the season winds down.
