Hondaman ignition
« on: November 22, 2014, 04:05:48 PM »
Do you have to disconnect the condensers when you install the Hondaman transistorized ignition?  If so why and what would happen if you leave them connected?

Yes you disconnect the condensers.   They are not needed with the Hondaman system as the points are merely a signalling mechanism for the Hondaman box.  It is easy enough to disconnect them as each one is only one screw.  I generally follow the directions and get good results that way.  No idea what would happen if you leave the condensers connected.  Don't think it would be good though.

No, you DON"T disconnect the condensors.  From Hondaman himself:

Quote
3. Points and condensors stay in place: this provides 100% backup if the electronics ever should fail. You can unplug the 4 wires to the points and coils, plug the points back into the coils, and hit the road again in (literally) about 2 minutes, even on a hot bike.

If the Condensers are old and not really functional? I disconnected condensers on my NOS TEC when I did not trust the shelf life of the condensers that might be very OLD.
When was TEC complete point plate in production? 20, 30, xx years ago or do they still produce them?

The reason for my post was, I have had the HM ignition hooked up for about two years now and it worked really well at first.  now my 750 doesn't seem to start as easy and almost feels like its not firing on all four for about a minute when she is first started then it feels like all four kick in and it runs smooth.  also the idle isn't what it was so I pulled the carbs and re cleaned them for the first time in about two years they really weren't bad.   I am thinking of reseting the valves, points, and timing next but I just wanted to make sure I had the HM ignition hooked up correctly.

Sounds like a tune up is in order.  Every 3,000 or so you should check for valve clearance.  I would get a new set of spark plugs too.  Check the gap on your points as well.  They should be nice and shiny with no pitting.  Get a timing light or borrow one to make sure your timing is still correct.

I forgot I had dihachi points in it so I replaced with some old but nice tec points set the gap @.014 set the timing and bam huge difference.   Took it out for a road test and got pulled over for not having my headlight on(bullsh#t) , but he was more impressed with my K0 than trying to give me a ticket.  I think he pulled me over just to see it ::).....Thank you for all the input and yes I LEFT MY CONDENSERS CONNECTED ;D

Did you set your valve lash and check with timing light?  I would do it while at it.    I would also check all parts of advancer rubbing block and give light oil or grease.
