Exhaust Stud Replacement?
So TXpowersports will NOT warranty this part, even though the bike is 6 months old..
Hopefully I can extract my broken exhaust stud, but I really don't want this happen again. Can anyone recommend a replacement? I'm not sure where to start. I keep thinking about going to the hardware store, buying a steel threaded rod, and cutting it to length (and I'm sure the threads are metric). Should I order a new exhaust stud online? If so what is the best option? |

Are you referring to the exhaust mount that is in the lower-middle part of the frame or the the one that holds the muffler in place? Unfortunately TX power sports won't take any responsibility for anything beyond shipping...once you receive your Hawk, you're more or less on your own. That's the one downside of owning a China bike...warranty's are nonexistent. If it's just an exhaust mount, it should be fairly inexpensive to have a new one welded on or use a clamp instead (depending on where it is).

You can pick up a new stud from your local auto parts. You can remove the broken stud by drilling it and use an easy out. This is what I use to remove broken studs on my truck. works great. https://www.lowes.com/pd/SpeedOut-8-...tor/1000170531

Yep, I'm starting to see that with TX Powersports.
Would you guys consider an exhaust stud as an engine component? I argue yes because it literally comes from within the head and without it the engine will not operate correctly... But I suppose I could see as a non-engine part like a turn signal but that seems doubtful. So just bring my good stud to Autozone and have them get a direct replacement? I bought some stepped left hand drill bits, hopefully if I work slowly and carefully they should work. |

I would strongly caution you to use a milling machine to remove the stud. It would be a 4-5 minute job tops VS a trashed head. You must pull the head to do this.
I just pulled 8 studs on my 53 year old tractor head. They were all to hard to drill on an uneven broken stud. After the 2nd stud let go at 12Ft Lbs on the torque wrench I'd made up my mind. Replace the stud with a good quality part, not an Ebay Far East one. If this job goes sideways a time cert sleeve can still save it if the drill walks off. Pm me if you want to use my mill.

Left handed bits are a start but you will probably need an easy out too.

I've had the best success with left handed bits by first drilling a small pilot hole using a conventional bit. The left hand bit then just follows the pilot, hogs out a bit of material and hopefully backs the stud right out.

Sounds like a good game plan, Also.. Tell yourself you gotta go slow, it could take a long time, and my not work out all that well. That keeps my temperature down when it goes slow, takes a long time and doesn't work out that well. anything other than that is a win.
when you manage to get it fixed you can still whittle on your free time. Good luck brother!

A new head is 87 bucks from CSC, but shipping ends up being 115 etc......just buy more odds and ends until you're up to 100 bucks, then shipping is free.

Size?
Anyone know the size of the studs holding the exhaust pipe to the engine head? Mine have apparently rusted to crap.
