CB750 / Re: Rattling noise when in neutral
« on: June 14, 2018, 10:57:25 AM »
Hopefully will be associated with the clutch. I am going to purchase a clutch pack I think from David silvers and replace at the end of the season. I will also acquire a Morgan Carbtune to do the carbs once everything is set up. Certainly an interesting learning curve - I haven't touched a bike since the 70's as mine have all been new , I've had this about 3 months and spent more time tweaking than I have sleeping !.

Thanks for that, carb balance next on the list after a quick check of other service issues.

When doing the balancing do you use any form of cooling for the motor whilst it's running ?

I think I'll use them as a last resort. I dived into the classic bike scene expecting and wanting to learn a bit more about them. So far it's quite enjoyable solving the issues. I hope I can progress to changing the clutch toward the end of summer and get the carbs balanced. If it needs more intervention then I might have to rely on someone who knows what's what as I'm sure I don't have the knowledge as yet to strip it down - hopefully it won't come to that.

What I have noticed after doing the static timing and the cam chain adjustment is the bike fires up much better. On tickover it clatters until you pull in the clutch ????? - clutch or primary chain ????. Also when riding in any gear you can hear what I can only describe ( hopefully it's an understood term) the drivetrain working. It's less noticeable say above 3-4 k rpm. I am not sure if this is normal for a bike of this age (k6) or if it's symptomatic of something worn ????. As the k6 is new to me I am on a steep learning curve.

CB750 / Suspension - hop.
« on: June 13, 2018, 06:30:14 PM »
My k6 up to around 50 mph had a rather uncomfortable feel through the handlebars to the extent you couldn't ride one handed.  After 50 mph it more or less disappeared but not entirely. The yolk nuts I thought were first to blame as they were loose. I re torqued everything up but it remained. I jacked the front wheel up yesterday ( new rims and spokes) and found the wheel had a flat spot ( in the vertical for almost half of the tyre ) and a slight offset ( left to right.). I have more or less corrected this but need a final tweak when I get hold of a torque wrench. If a slight bounce still remains do I put this down to the bike being 42 years old ( spoilt with modern damped suspension) or could I damp it anyway with thicker oil for example ? Any ideas ?

I wonder if we can define the difference between a rattle and a clatter ?, I would describe mine more as a clatter - certainly if the indicated revs are around a 1000. If I up them a little to 1500 it seems to be less noticeable. I actually question the accuracy of the tacho in any case as running it adj my Suzuki 4, even 1500 rpm read, sounds less than 1100rpm on my Suzuki!. I read on the forum that a replacement clutch with one of the plates having a wider tab ?????. Not sure if this means anything to anyone, I assume the wider tab means that the plates won't clatter from side to side as much ?. I guess in the first instance a carb resync is advisable and take it a step at a time. I've set my static timing & cam chain as per the video,does anyone have a decent link to a video or paper on setting the dynamic timing with a strobe ?.

Hi, I recently purchased a k6 (cb750) - I have a few questions I would like to put to a knowledgable owner. Ideally I would like to meet up with someone in the north west of the U.K. To have a chat ?. Perhaps a meet for a coffee. I want someone to listen to the bike and guide me on certain mechanical issues ?. Any help would be appreciated.
Regards
Paul

Hi, I also have this problem. It sounds awful at tickover ( in fact it's embarrassing). I pull in the clutch and it more or less disappears. My clutch grabs when the lever is almost fully out so I thought it might be the clutch ? That was on its way out. I've just reset the timing ( static) which was out , so at least it now starts on the button ( before I could be there 2-3 minutes  waiting for it to fire). I will now reset the cam chain, I may have to consider rebalancing the carbs as many say the rattles and bangs are as a result of imbalance). I hope it's not an issue with the primary chain as I assume that's a strip down job ?. I will keep you posted as I progress.

Thanks deano, my everyday bikes are a Suzuki GSX 1250 FA which is a great bike for the all round stuff such as touring , trips out for the day etc, the Bonny I just loved it's look and I tend to use it for the more local trip. The Honda is my initiation into the ' classic scene' I will see how I get on with it before I delve deeper I think. I just need to get a few miles under my belt on the Honda to get to know it, I hope I get to really enjoy riding it as much as I do the other 2

K6 finally registered and on the road. Managed a short run to clear its lungs a little yesterday - interesting experience as I have not ridden a similar bike since 1976 when I last had my Honda CB 500/4. All my riding has been on more modern m/c's with efi etc. After struggling out of my village up hill with it spluttering away , I realised I had left the choke on ( first mistake - use to auto chokes), ride felt a little unstable so have reduced tyre pressures to 2 below recommended. Adjusted chain. Guess one has to just get use to thinking this is a 42 yr old bike and it's not going to be super slick !!. You just have to love them for what they are. The engine is smooth as is the gearbox, clutch rattles / clatters away on tickover but as soon as its pulled in  - sounds fine. Reading the threads this sounds reasonably normal ?.
What I would like to do is get to know how to service this beauty properly so any advice on essential equipment for points / carbs / valves welcomed ?.
Hope to bump into fellow owners soon.
Regards
Paul

Just a thought , in all my years of riding more particularly in the last 10-20 years I've still not seen any body riding a classic Honda in the area nw uk ?. When mines registered and hopefully reliable enough to get some miles on it I hope to visiting a few of the local haunts in Derbyshire so stop me if you see me, I'll be on a k6 750 which is finished as a k2 ( red). Look forward to a chat.
Paul
