    XR200R blue smoke?

    I'm only a forum member on this site and you all seem very knowledgeable. This engine is also very similar to the TW so I thought I'd run this by you guys and see what you think...

    So we picked up a 2000 XR200R last weekend and it appeared to run smooth and clean on first look but once we got it home it's been blowing blue smoke at higher rpms. We've yet to open it up and are researching and plotting the best strategy to resolve it. It has plenty of power so we're thinking the bored out cylinder and piston are OK and it's likely the O-ring gasket (or lack of) between the cylinder head and valve head. Normally this gasket would seal the oil route to the top of the engine but it's running out just above the piston. So much so that it burns almost all the oil to one tank of gas. It also sounds like the valves may need adjustment.

    So I'm thinking if we buy a gasket kit we might end up having all we need to resolve the oil burning. Assuming we're correct in our theory.

    The other issue is first gear is a little tricky and only slips in gently when rolling forward if I understand this correctly. I have't rode it enough myself to diagnose this part...and may put this one off till later. It would be nice to have it running for the summer.

    There are some reduild videos on youtube that give me the confidence to take this on so if I can find a service manual I think I'll be fine but if you have any tips/feedback on what I might expect please share...

    If the gasket kit works to reduce oil consumption then investing in something from the AMSOIL line might improve shifting too. oil.jpgBoth seem worth trying before investing in a major motor teardown.
    XR200R should be a sweet bike for those Nova Scotia trails, worth keeping happy and healthy.

    We might have to give synthetic a try...

    In the meantime how bad is it to keep riding it if we keep topping up the oil? Short bursts checked frequently. I imagine the top end would still be getting some oil. It could be a week or two before we get to a rebuild.

    Best advice is pull it apart asap, don't delay the inevitable. The sooner apart, the sooner togeather. You'll need a gasket kit anyaway so order it tonight. If it's only that, you'll be posting videos of you riding it by next weekend. They are fairly simple motors and you're a very smart person so I consider it easy peasey for you

    Thanks JJ. I appreciate the vote of confidence.

    It's at least a gasket kit and a service manual. I could use the torque specs and timing alignment descriptions. I looked online but didn't have much luck finding a PDF version to download. I may have to order one of those as well. I guess I could take notes from youtube and google searches if it came down to it.

    Done...top end gasket kit and service manual on the way. ETA 10 days. Time to clean up the shop. Once that's all done we'll try the synthetic oil.

    Oh yeah and I think the xr200r is one of the closest matches to the TW for tight trail riding. But now I need to uncork the TW.

    I'm sure nothing I do is anything new or that dramatic but it all adds up. My goal is to achieve more acceleration and still reach 90kph/55mph top speed with out redlining.

    I plan to ...
    - Drill out the welch plug and adjust the fuel mix.
    - Put on a 54 tooth rear sprocket and maybe a smaller front depending on the results.
    Considering...
    - Remove the inner snorkel from the air box. It looks like only one edge of the snorkel keeps dirt out and the rest restricts air.
    - Maybe remove the spark arrester, drill out the muffler a little, and replace the spark arrester.
