stripped oil plug threads

[bf750superduty]

i was changing the oil in my 03 kodiak today and pieces of the threads from the hole came out with the bolt. what do i do now. retap? heli coil? any ideas. The bolt itself is fine. Does anyone know what the size of the plug is

Hey, I would'nt use a heli coil, it is a risk that it gets in side the motor, if it was me, I would get a bigger plug you from a parts store and retab, always check the seal, clean the thread and never over tight the plug.

how do i know what the next size up is
do you know what the factory size is

[YFZ450-Tampa]

I really don't, but you have to meassure or get a die set and find the closest, you need to have the replace one to make sure everything fits fine

i found out the size i have its a m14x1.50 does anyone know what the next size up is so that i can tap it

[atvtrailer]

m15 is the next size, they go up by 1mm, same size thread, unless u wanna change the thread size also

[YFZ450-Tampa]

You should go a couple of mm, so you can go over the old thread, and make sure you get a plug with the same tipe of thread 1.50

Couple of tricks for when you drill/ tap it. If you can have someone blow compressed air through the oil fill hole. It will keep the metal shavings from going into the motor. They will blow out as the bit cuts. You can also put wheel bearing grease on the tap and drill bit and clean it often. This will also trap the metal shavings and you don't need air. Good Luck!

Uh-oh, that doesnt sound very good.  If I were in that situation, i would risk the chance of retapping it and possibly not doing it right or using the wrong bolt or what ever else could happen.  Your best bet, but it might not be the cheapest, would be ot bring it into a machine shop and have them retap it to the correct size.
