Title: CB175, Electronic Ignition???
Post by: Isleofmanfan on November 01, 2013, 07:12:42 AM
Hello,
        does anyone know if there is an Electronic Ignition kit available for a road going CB175?

Regards,

Mike

Doesn't the CB have two sets of points? Don't think there is an electronic kit but Hondaman on the US site does a kit for the fours that reduces the voltage and current at the points so they don't spark and wear out so the spark stays better for a long time. If I am right about the twin contacts it should work on the 175

Thanks Bryanj...I can only see one set of points!

Is that where i`m going wrong?

CB175 had 360° crank (both pistons go up and down together) so used wasted spark - just like the fours.

That's why they sound so good compared to the CB250/350/360 which had 180° crank and uneven firing sequence.

You are probably correct Steve, it's been a long time since i worked on one

You can use a Sparkrite TT electronic ignition on the CB175, it retains the points, but using a much lower voltage across them, resulting in much longer life for the points and less frequent adjustment. Found just what you need on e-bay, item number  151154496435   he's got 2 of them, apparently new and unused, probably worth a punt if you want to go down that route ;D

Is the Hondaman box the same idea as the Sparkrite?

Cheers....

Got both of them for £10.50  ;D Fitted one today and there is a vast improvement.

Should I do away with the condensor all together?
