    Just wondering if you guys play around with your old/new mowers and try to better the performance? Or to get better fuel consumption

    My mods are a K&N filter on my two toro Z's but thats all so far.
    Include pics or detailed info.

    I removed the inner debris shield from the motor. I then lined the outer shield with screening.
    With the inner shield ( the one that spins with the engine ) removed, the engine seems to have better air flow. :drinkup:

    I've been so pleased with our new Z that all I've done is sharpen the blades and balance them for smooth cutting. I did notice one of the hydros made a slight moan when the parking brake was engaged so I adjusted one linkage rod one turn and that seemed to quiet the sound. Other than that I'm just riding and grinnin' :cool: We did turn the governors up on our 21" walk behinds
    to a respectable 3600rpm. I don't how anyone could have cut with the low factory settings.

    Would you not have to re-jet your carb. for a K&N filter? I know if you want to run a K&N on ATV's you have to re-jet. I would assume that it would be no different...

    About the only tweaking I do to my mowers is the engine rpm's. I bought a new machine (small ztr) and put the tiny-tach on it and it was running at a whopping 3100 rpm's with the blades running. I call that stall speed!

    Iv'e ran synthetic oil but there's so much mixed opinion on weather that is good or not I want back to the "cheap" dino oil. I see no diference in how much oil the machine uses in a given time on syn, or dino. and it was always a pain to keep the syn. stuff around as well as everything else.

    He may be thinking of when you add an aftermarket pipe. Then you need to re jet.
