1967 CB450K0 Black Bomber Rebuild - By Royhall

Just got a spare starter assembly from DK. Cost me £138, I think they have realised the value. He only dropped £5.95 on my offer then just £1 so I bought it. There was already 10 watching and it was only listed this morning. Nice to be first for a change.

Nice one Roy  .. I still think that was a good price ...The Yanks sell just the individual parts for that much ....then you have all the duties/shipping etc .... store as a spare and better than money in the bank if you don't need it.

I also got from another eBay purchase a broken rotor and a clutch outer and bits for £20. It's just arrived and the rotor is perfect but the clutch is bent so wrong way round. What they sent was not the picture I bought. Anyway, checked the rotor marks with my overlay and it's different. TDC and the timing marks are the same but full advance is about 3 degrees retarded. The second advance mark is on the overlays first, if that makes sense. It's stamped 375, doesn't help me as I'm about 15 degrees advanced but proves they are not all the same.

375 is 500T  .. I just sold a NOS one on eBay

[royhall]

I shall clean it up and get it back on eBay as the rotor part is perfect. You never know it may pay for the new DK one. How much did you get for the 500T rotor?

£150 it was NOS though in the Honda packing. (Paid for my DK CB 450  rotor/clutch assembly) ...CMS are charging over £300

I think I will try a 7 day auction starting at £120 and see if there's any takers.

Bit of success over the weekend. I took off the electronic ignition and refitted the old points plate and remote condensers, they are pretty worn out but will do for checking out the problem. It static timed to the marks no problem and the engine started okay. It was running pretty rough and the points were arcing like crazy so I guess the old bits are fooked. Anyway, it ran well enough to warm up and strobe, and incredibly it strobed up to the marks so looks like the Pamco ignition is the culprit.

I tried to email PamcoPete for help but unfortunately he has retired and not answering emails. I'm told he was ripped off by another company that stole his designs and sold it cheaper so that finished his business. That and the fact he's USA based leads me to think the Pamco is a dead loss that has no chance of being refunded. At least I know what the problem is, now I need to sort a solution to the rough running problem. I'm thinking a Charlies Place electronic ignition as they appear to have rave reviews unlike the Pamco.

Why not chuck an old school set of points and condensers at it?

My CL450 is on the original clockwork ignition, she starts instantly and runs without missing a beat. I quite like the idea of using technology I can understand and therefore fix, electronic ignitions are great while they work, until suddenly they don't anymore.

[royhall]

Personal preference I suppose. In all my years of biking I have always used electronic ignition and never had a single issue until now. I do like the set and forget aspect, plus the cost and availability of genuine Honda points for these is prohibitive and I certainly wont be using Diechi (is that how you spell it) points as they are awful.

[AshimotoK0]

I agree with Dave .. I am an electronics engineer and I should be promoting aftermarket electronic ignitions I suppose but all of my bikes will end up with the original points setup.  It was different back in the day when  I biked to college/work ever day for 17 years. In fact I built my own Cdi for my 1st 400/4  and used it for 2 years with that fitted & 20k miles  .. but I suspect most most resto's on here will do very few miles.

[royhall]

Your maybe right. I shall have a think about it but I really do like the fit and forget aspect. I put my 750F2 on points originally but it came close to letting me down 20 miles from home with no tools, just managed to limp home. Those points lasted 400 miles and were shot. Fitted electronic and it's run great ever since. They were Silvers finest points, Diechi I guess.

The thing I like about the Charlie's Place system is it retains the mechanical advancer. That part is pretty reliable so does away with the ebox. Looks to be a neat system and gets lots of good feedback. Sirrus are selling them so sod it, it's getting ordered. Not added up what this bikes cost, I don't think I dare. The costs have shot up right at the end, just when you think you've finished spending. Don't think I will be making a packet on this. Why do we do it.

I thought I may email 4into1 who sold me the Pamco but just checked the invoice and I have had it for nearly 3 years. I think the warranty has expired. Where did all that time go, 3 years and the bloody thing still isn't on the road.

[MrDavo]

I learned when I was racing that you should never add up the cost of your hobbies, or you definitely wouldn’t do them. Conversations about how much a season cost were definitely avoided like the plague when the wives were around.

If you’re happy with your new fangled space age electronic ignition then go for it. However I’d prefer to limp home again rather than coast to a silent halt. Plus if I don’t understand it, the only way to fix it is to substitute parts, which can become expensive.

You could always look at the Hondaman alternative.... best of both worlds as it uses the points to trigger the Electonic ignition and can be converted back to straight points in a flash... just a thought.
