    I've done a few top end rebuilds on 2 strokes, but never on a 4 stroke. Wanting to rebuild my 510 before spring here. Any special nuances or tricks that I will run across that is special to this bike? OR is it pretty basic? I know on some bikes you have to actually remove the motor from the frame, I'm hoping that is not the case with this bike. Also bike has about 8k miles on it. What are some signs to look for as far as other wear items, like valves etc..? I heard these have a history of connecting rod problems, anything special to check for there?

    My plan is just to do the piston and cam chain.. any input would be apreciated.

    Hi Luigic81. If you are going that far then you should have a good look at your valves, valve springs and valve seats-good time to undertake this job when you are taking the head and cylinder off. I would also do a proper carby pull down maybe replace jets.
    Not sure ablout an in situ pull down. I am pretty sure on the 06 TE's you can not sure on the SMR's. Someone out there in Husky land will chime in with the correct answer.
    Would really like a diagnostic report of what you found, what you ended up doing, the cost, and how she goes post reconstruction.
    good luck with the job.
    Ciao.

    thanks, the carb is already dialed in. I have adjusted the valves once since I bought the bike, and it was only slightly tight on one end. So what exactly would I look for as far as wear on those other items (valves and valve train)?

    I would make sure that the valves were seating correctly ie did not need replacement or a seat grind
