    Thoughts? Prayers? Advice?
    Don't hone it yourself this time. You ruined it.

    Lots of oil ended up in the cylinder.

    Good news is that it's just a motor.

    You'd be further ahead to take it somewhere and just work the hours it takes to pay for it.

    Still a lot of vertical score marks, but can you take a picture of the top of the cylinder? Can you feel a ridge at the top of the cylinder? A 3 arm hone is only going to follow the out of round shape and put new scratch marks in it. It won't actually make it round. I would just go oversize piston and be done with it. If you can't get someone to bore and hone it PM me.

    Shad Owe:

    What do you see in the pictures that makes you say that I ruined it?

    Thanks man! Here is the top of the cylinder:

    I do not feel a ridge at the top, all very smooth, however...(Full disclosure-Paul Harvey)

    I did not put grease on the rings before I installed...my bad.

    I wet tested the head.

    Then I got to wondering how long the WD-40/blaster mix should stay without any leakage so I asked MrC and about an hour later he told me "15 minutes"

    So I went to check it again.

    So for once in my life, I feel that my head is ok...

    Shipping out to G&C ATV Discount in Somerville, TN this morning. That guy does a good job at a very fair price.

    I'll be back, as the Saga continues.

    If you look at the top maybe 1/4 of the cylinder it looks to have a nice crosshatch. That's the way the whole cylinder should look. New rings won't seal on the polished surface below that. As for heads, as long as the valves aren't bent and you have some lash it will run fine.

    Lol. If you think his hone job looks good I'll be sure to never pay attention to any of your advice.

    "Grease the rings"? Lmao

    Take it to someone. You have no idea what you're doing.

    Shad Owe:

    You are correct; I am not an expert by any means and my knowledge is quite limited.

    As stated in the earlier post, the cylinder is on it's journey to G&H in Somerville, TN.

    But you didn't answer my question...

    I can tell because of the way that it is.

    Your pattern sucks and the scratches are way too rough. First of all once a cylinder has rusted you'll never just hone it back by hand. If you don't have a bore mic (or possibly even know what one is) you shouldn't be holding a hone.

    If I had to guess I'd say you installed the used rings. They scraped that hone off in seconds, although new rings wouldn't last long either. Can't you see how much oil blow-by there was?

    Anyone who has ever properly honed a cylinder should be able to see that you were way too aggressive with the hone. Most people who suggest using one are forgetting they never got their own project running right. Honing is something that takes practice and failure to even be OK at. Anyone says otherwise has gotten lucky or has a misconception.

    The big lesson here is to NEVER EVER make a one cylinder engine a SAGA. You either got it or you don't. Once you realize one way or the other accept it. It's way more of a flex to have a known pro do the work than it is to slog through it and pay triple for a maybe ok engine.

    You're taking advice from someone who had to take their motor out three times but there are pros who could rebuild it blindfolded hanging upside down over a fire and it will be perfect. Consider that.

    Sorry I meant top 1/4" not the top 1/4. The hone only hit the part above where the top ring gets to. Honing is not hard if you have the right machine, tooling and gage.

    Hey patriot1
    Looking at the cylinder there is almost no crosshatching half way through, im sure that Gand H will bore it to the next size. Did you ever mic it? What bore is it now?
    Your reading of 100psi to me was the tell, freash rings on a decent crosshatch should higher psi. I think your on the right track now.
    It can be frustrating when you have multiply issues at the same time.
    Stay positive, you will get it right.

    Ok guys: here we go again.

    Persistence pays off

    Quitters never win, winners never quit.

    Or maybe I just wanted to give Shad Hoe more reasons to ridicule me so he can feel better about himself and not have to think about his ED.

    Got stuff back from G&H Honda, try them. Great prices and fast turn around.

    Slow day today so not riding yet 350, but progress was made.

    Engine installed. MrC says it's a 15 minute job, I disagree but it was easier this time than last time, so maybe I'll get to 15 minutes one day?

    I realized I didn't have any oil and I have been missing this spacer and a front hanger bolt since I got this bike.

    Where could I get the spacer and bolt? Please allow me to introduce you to Saga II.

    We'll refer to Saga II as "Dog" for the time being.

    To be continued...

    This was actually the first 350x I ever bought. It was extremely hard to kick and this was when MrC was dealing with his first 350X that was also hard to kick.I was busy with other projects and knew the hard to kick was over my head, so it sat...

    Until I needed a spacer for the upper rear engine mount on Saga.

    I pressure washed it and discovered a few things.

    1) the rear has been welded.

    2) it has a twist throttle

    3) Different carb-possible 300ex???

    4) tires suck

    5) low quality spray paint (and overspray) on the frame and other parts.

    6) real dog

    7) are you ready for 7???


    IT HAS AN 85 STICKER BUT AND 86 ENGINE THAT IS VERY CLEAN AND GOOD!!! OH YEAH!!

    I looked at the decompression cable and noticed that it was way out of whack so I adjusted it.

    And after I got Saga I to start and run...


    I got this old b****h to do the same!!! I had basically relegated it to parts!!

    Today was a good day!

    Cheers!

    Congratulations on getting it running.

    Now you can start tuning it up and servicing things that need to be serviced
