    Kohler Info

    What's the most cost effective way to bump-up the HP and torque of the carbureted Kohler command series engines without excessively compromising reliability, mandating the use of exotic fuels, or creating a 130 decibel exhaust note?
    Is it even doable, or are they at or near their upper limit in stock configuration?
    I can't seem to find any info on this topic.
    Anyone know of any builders/tuners doing this??

    hi , with out saying to much if u have a alternate choice eg vanguard go with that [mainly due to cost ]
    As with any modified engine u will at least recondition and then modify ,this is where the cost can go vertical
    Go and check out MIDWEST SUPER CUB
    new rings at least
    send engine block to machine shop for crankshaft bores to be sleeved
    heavy duty valve train
    after market con rods
    advanced timing
    improved exhaust
    if u have a 23hp [stock 26 mm carb stock] replace with 25hp accelerator pump carb 28mm
    after market camshaft
    Keep the revs to 5500rpm and below [possibly retain original clutches ]
    Keeping the rpm conservative means u will not be putting to much heat into the pistons otherwise u will need forged pistons
    inlet manifold IMO are pathetic on kohlers vtwins
    Screwed on timing magnet on fly wheel replace with after market unit
