    '72 CL175 engine trouble?

    I read on some other forum some guys suggested putting some in the cylinder to soak in. On the bottle it says add to fuel (4oz per 10 gallons) or replace up to 20 percent of your oil with MMO. To me that sounds excessive. I'm just gonna try it in the fuel for now. It's been cold as hell...

    2 Stroke v 4 Stroke for City Riding

    I would think one big headache with the two strokes are that you cant just fill up at the gas station and go. You have to buy 2-stroke oil and make the oil gas mixture.

    '72 CL175 engine trouble?

    Last night I checked timing, valve clearance and the petcock. Timing was a couple degrees early. I rotated the plate very slightly so the test light comes on just as the F mark lines up with the index mark on the case. The valve tappets had moved a bit since I set them before. No...

    '72 CL175 engine trouble?

    I'm not sure how long it was sitting but obviously a 45 year old bike with 5000 miles did an awful lot of sitting ;). When I drained the oil it was black and smelly. I have heard that bikes which sit too long tend to develop pits in the cylinder at the spot where the rings come to rest. I...

    '72 CL175 engine trouble?

    Here's what the plugs look like. The left is looking nice and brown. That's the cylinder with the lower compression. The right looks a little oil fouled to me.

    '72 CL175 engine trouble?

    Thanks for the advice. I was not expecting to rev that high. I have always had larger bikes before. I'm not expecting to set any speed records on the 175, just hoping to do around 50 mph on the back roads, so if I can just get a bit more out of it...

    '72 CL175 engine trouble?

    CXman thanks for your suggestions. It has an electronic ignition upgrade (from previous owner). Don't know much about those ... are they maintenance free? I did adjust tappets and cam chain tension. I may double check the tappets. I agree, next step is check the petcock. Also I am gonna...

    Good to be here, greetings from NC

    I used to ride through Saxapahaw all the time when i lived in White Cross. I hung around the shop at Davis Customs in those days and leaned a lot from Randy and Spud. They used to have a fantastic 1930s Henderson motorcycle in a back room that was just gathering dust. By the way friends, I...

    '72 CL175 engine trouble?

    Hi all, I have a CL175 I am working on and I have a problem with getting it to go fast ;D. I should say I am the mechanic's equivalent of a tenderfoot - not a novice but not highly experienced by any means. The bike revs up nice in first, 2nd and 3rd gears on the flat straighaways, but...

    Good to be here, greetings from NC

    I've joined this forum after getting a lot of great information from browsing the posts. Good to be here in the company of many experts and, well, colorful people! I am getting back in the bikes after a long break. I first bought a CB750A (queue the laugh track) ca. 2010 and got my feet wet...
