Topic: Shimmed points plate - still not enough room

[tlbranth]

Meaning that you think plugs 2 and 3 don't have a powerful enough spark?

Meaning your 2,3 condenser might be bad. Points shouldn't spark much - that's what the condenser's for.

Well I played with it a little more. The gaps were dead on, the shim was nice and tight, so I decided to bust out the dremel and lengthen the adjustment slots. The top slot was much longer than the bottom two, so I lengthened the bottoms to match the top. A little tweaking and both firing marks were dead on. I went to start it and it starts first kick now.

What brand of points are you using? You shouldn't have to modify anything to set the timing with stock quality components.

Oh points aren't supposed to spark very much? My 2.3 point is constantly sparking. Thanks for the tip scottly, those crappy points are exactly what I'm using. I can't believe I didn't come across that thread on my own. Does anybody know where to buy legit Honda or TEC points/condensers? I might as well swap them all out.

Your local Honda  shop still can get the TEC points sets. The whole plate is less expensive than buying all the pieces, and the TEC baseplates seldom need the shim treatment.

Be sure to check the 2-3 points set under a timing light: if it "jitters" then you will need to also straighten the points mounting shaft. These can get bent from turning the engine backward with the plugs in place, although the 750 suffers this much more often than the smaller engines.

Cool I'll give my local shop a call in the morning. Hopefully they have what I need. Thanks for the tip.

Best price you'll find on a TEC points assy is here:

That leaves me wondering what baseplate TT has...

Unfortunately their exploded view is not correct. There are supposed to be little spring washers together with the flat washers under the little breakerpoints bolts and bolts that tighten the secundary (2+3) plate.
Please see pic for correct lay out.

ah... good point.

Dr. Noisewater - your local dealer will most likely quote you the list price.  Make sure you tell them you'd rather buy local, but for $40 bucks you're willing to wait for the mail to arrive.   

Actually, I bet the local dealer will need to order it anyway, so unless they have it in stock or will price match, it's easier to have the part mailed to you anyway.

[Dr. Noisewater]

Yeah I tried to call my local shop this morning, but during the winter they're closed Mondays. I know they're not going to have it in stock, they don't carry anything for older bikes, and they'll probably try to sell me Daiichi's in disguise. I'm disappointed every time I deal with them. I figure I'll just order them online. Now to find the right place to order from..

tlbranth's link seems like a decent deal, but deltarider makes a good point and after clicking the link it says it's for a 750 k5. Is the 750 points assembly interchangeable with the 550?

[tlbranth]

Sorry, I thought I read '75 CB750. I looked up the fiche for the 550 and I see no points listed so I'm not sure what the story is.

[BobbyR]

I don't mean to throw a turd in the punchbowl. Have you considered a PAMCO. I grew up with points. I like a set and forget it setup.

[Dr. Noisewater]

I'd love to go with a modern setup, but this build has far exceeded it's budget so I need to stick to the basics. I'm still looking for a good place online to order the oem assembly. If anyone knows of a place let me know. Thanks.

Anybody know anything about these..?

Maybe give South Sound Honda a call, once you have the part number. They are VERY helpful, and the best prices I know of with the OEM parts.
