I have 31hp mudbuddy. I am not the most mechanically inclined so was wondering what were some of your opinions for mod my motor???????

Not being mechanically inclinded, I'd start with carb and exhaust. Both are fairly simple bolt ons.

I'd get a 35 carb, cam, heads, and exhaust.

Just curious what length outdrive is that

Not sure where u measure tron but the back belt housing to the end of prop 42 from grease housing to b4 prop 35 and to end 39

Im building a 31 right now cody has.my heads doing carb exhaust cam and setx heads ill let u.know how t runs did 26 with 2 people light load before trying to get 30 - 32 with an ok.load

i started with single carb and crossover exhaust ...... what big difference so far . thats apretty good starting point and anyone can put these on themselves

lefty loosey, righty tighty.

A cam swap is the same concept as anything else
Its not like you have to grind the cam out of a stone, just align the timing marks.

Woodie, you left out pistons and rods. If you're gonna do it, do it right.

your right, if he has the heads and the crankcase cover off, he might as well unbolt all of four bolts on the rod caps and replace that too.

A good pair of mods to start with is a plutonium powered flux capacitor and a nitroglycerin fueled carb.

If you know what a feeler gauge is and how to use it, go with a new carb with an accelerator pump, custom heads, and open exhaust. Adjusting the valves is really the only technical part and it's easy if you use the right technic.

replace the frame with a surface drive frame, which is about 3500$, and also cheaper than fully modding your motor

But on a more serious note, carb, exhaust, and heads.. the heads arent too tricky you can youtube the crap out of how to adjust valves and figure it out.

looked like a longtail on my phone screen- I was so sure of it I had to pull a pic of it up on my computer!

Thanks everyone for all the comments and helpful info
