I was wondering if anyone came up with a performance muffler that matched up to one of these machines.

 

Oh well guess I will have to custom fit one.

 

i modified a big-gun exhaust...

That looks geo. Was it a universal model like I have heard fmf makes? Or was it for some specific model that was pretty close? What did you have to do to make it fit?

 

it was their trx90 model. I had to order some mandrel bent ss tubing bends and a short straight section to get it to fit. also revised the bracket on the muffler. aside from the multiple seams, looks pretty factory. sounds tough too.

 

Thanks, I'll bet it sounds much better. Does it have a spark arrestor, or is it just a muffler?

 

Nice job on putting the grease fittings on the a-arm bushings. Does it work well? My son's Yamoto 150 does a good bit of squeeking.I will have to try this.

 

the zerts were already there ( ! ). i modified the a-arms by widenening them by 2" each side, and relocated the steering stem about 2" lower to reduce the bump steer issue (see the avi files).

 

Wow. I just assumed that was aftermarket. My son's Yamoto 150 doesn't have them. But in my opinion, it should.

 

There are no zerks on my wifes yamoto 150. It does sound like a good idea though. May add them to my project list.
