Hello everyone,my name is Rob. i have a 1970 honda cl175. I bought brand new carbs and pod filters (I know a lot of people hate pods) my factory ones where shot. The one boot was ripped in half and the other was in rough shape..anyway so I installed them and cupped the exhaust (no muffler, straight piped) it runs and idles sometimes its a little rough and back fires/bogs at idle revving it. I adjusted the air fuel screw a tad which helped it run better not as bad with bogging but I know I should re jet it to run this set up.

I am also on the fence with either doing the lollipop mod in the pipe or building the day baffle..not sure. So my question is does anyone know a proper size jet I should run in it? I do not know the size that's in it at the moment,they are brand new factory settings so I'm assuming its stock jetting.

I do apologize for any annoyance and noobness. I've ridden all my life 2 strokes and 4 strokes but this is my first motorcycle twin. I understand that I do need to re jet I just don't know if there is a common size that I should run. Like I said it runs and rides fine but does backfire sometimes (like a lean back fire) its not rich not black smoke which is rather have. I will be pulling the plugs to see how they are burning.

Thanks again and I appreciate any feed back.

Rob

I'm in the same boat. My 1970 CB175 has been cut by the previous owner, as well as the airbox being replaced by pods. Did you ever get yours running right?here's a couple pics of when I got it to now.
