    74 max 2 chain and sprocket upgrade ???

    Ok guys a few questions about changing the #40 chain and sprockets to #50 chain and sprockets and will it interfere with the brake drums and such?? We're thinking about swapping thses sprockets out and looking for any advice before we start buying parts.
    Thanks for any input on this!!

    Racers don't need brakes. They only need extra strong throttle cable and hard grip to keep it wide open.

    50 chain will be fine. The only problem is you have to change the chain adjusters

    egoperf do you happen to know the tooth size on a 50 chain sprocket compared to a 26 #40 sprocket?? And change adjusters how?
    thanks

    My old II is a 74and I just installed a newer set of sprockets and tensioners for the wheel chains. I'm not sure if all that is different on tensioners is the slide block. I can't find any # 40 tensioners in the spare parts pile to check out. Maybe someone else knows if the rub blocks are the only difference.

    lolol yes frabbit you are correct!! but this is my buddys machine and the sprockets are iffy at best and we discussed a 50 chain sprocket and chain swap and was hoping someone out there in the 6x6 world has done or tried this already.
    I've come to the conclusion that my body may not be able to take me driving a racer!!! Ya know old and fat!!
