Title: Tips on starting CD175
Post by: oldh on February 05, 2020, 06:56:26 PM

The 1975 bike's a good runner but a pig to start from cold any ideas?
Cheers

p.s. usually goes with a bump.

Check the choke.

Most Hondas need it in the cold.

Check ignition system.
Plug.plug cap.coil.HT lead.
Also Carb.jets etc

My first port of call would be the plugs, check the gaps and perhaps change them if you are getting a weak spark.

Check your points gap and timing. I can start mine from cold when it's on the bench with my hand. They do need full choke when cold. Welcome to the forum.

Many thanks guys. I think that I have given all the points that you mention a good dose of looking at and setting up to what I think is correct. However, I will get the manual out and go over them all again. I was never sure how much or little choke to give, so will apply full choke next time out.
I am sorely impressed with your hand starting Moorey, I'm obviously missing something somewhere.
I'll keep you posted on how I go on, but it will be a few weeks as the bike is currently overwintering at my sisters garage.
Thanks again and kind regards.
Dave

Trig starts my 400/4 by hand just by pushing down on the kick start, he makes it look so damned easy 🙄🙄🙄🙄and my bike has got excellent compression.

It's easy.I start my little Yam by hand.

And the 2 Hondas by thumb.

One press and they go

Oooooh!!! Now I really do feel sorry for myself. Must be holding my mouth wrong or something! I'll have to get a grip of this one.

Look at changing the condenser, if it's original then it's over forty years old and possibly on its last legs.

Thanks for that adespin. I think that I've covered all the electric side, i.e. new coil/leads, condenser, points, plugs. But must make sure that I have them set up right. Also it's possible that there's a faulty unit, I have heard of that even from a brand new item.
I should have said this at the start of the thread - dummy me!!!
Thanks again for your comments.
