2002 Max II 18hp vanguard swap to 25hp kohler help

The governor may be set too low as well. I had another machine with a 18hp B&S and the governor was set at only 3000rpm, after adjustment to normal operating revs it worked out perfectly.

Which may very well be true. I havent hooked up the tachometer yet to see what the motor is turning. Kind of been procrastinating that one for some reason haha... I even have it already sitting in the box. I do need to check that yes.

Many of the max II's you're running with may already be turned up, a couple hundred rpm make a big change.

it is kevin griffins machine that i ran against and shannas and kennys.. all kohlers and i'm sure they have them all turned up. But I want to do it safely.... not sure they did it safe haha

Well got my tires on and they work awesome. they dont stop pulling in the mud. And the clean out really well..... Havent been in anything serious yet. And they also do swim. Slow.... but they swim......... I also added a SPAL 6" fan from jegs.com to the exahust side to expell some heat and that seems to do the trick. Only time will tell if 1 fan is enough. Should know more when I ride in ashtabula in a few weeks....... With these tires and 1" spacers i bought the machine needed mud flaps drastically..... I do Have a picture but the file is to big and i'm not savy enough to reduce the file size to upload. But anyways. Cant wait to ride more

That turned out really good. It's amazing the difference that those tires make. I'm sure they will make quite the difference on the trails as well.

Thanks mike, I wouldn't change a thing. I've done some small riding around by my house and these tires just keep amazing me everytime. Biggest factor to help is the ground clearance. I'd suggest to anyone to put 25" tires on there machines..... Unfortuantely I had bought my tires before Mudd-ox mentioned that they were supplying 25" rawhide III's again which is the way to go in my opinion.
