Need help tapping out some bolts on my rc

So I was pulling the tank on the rc and there are two bolts that are located close to the stearing stem that bolt my tank and fairing stay to the frame. Well my luck both bolts broke off into the frame. I am needing to get these bolts tapped out and new bolts put in before next weekend sept 14 we are going on a trip to leakey.

My work schedule really only allows me to take the bike on a saturday.

I really like Motorcycles Unlimited but they said they probably won't be able to fit me in due to how slammed they are on saturdays.the price is good just can't get there on a week day.

Hop is getting back to me today if they can do it saturday. They have the best price so far haven't used them but have heard great things.

Called honda of houston. Prices are insane. As well with any other dealership I called

Anyone know a good machine shop or anyone that is capable of doing this?
All help is appreciated

How deep are they in the hole?
Did the head break off? Threads exposed? Pics?

any good welder should be able to get those out. They will build up some weld onto the end of the broken bolt and form a nipple that they can get some vice grips on. The heat itself will free up the bolt and it will usually just back right out. I use a guy named Randy Porter from Lonestar Metalwerks near Bunker Hill and Longpoint

Flyin' Duc is likely capable...as is Wil Kitchens over at IDB racing. I don't think either is open on Saturdays, but they may be willing to meet you after hours with an appt during the week. Worth a shot.

Yep....
Depending on how its broken....some JB Welding (ghetto effective) a smaller bolt to the top of the broken one has been known to work

Go to Harbor Freight and get a set of left handed drill bits and a tap punch. Punch the center of each bolt and start with a small bit and work your way up. Eventually you will remove enough of the bolt center it will flex and reverse right out.

If you get them out and the threads are boogered up pretty badly you might be better off helicoiling the threads so you still have some strength in the connection. The most likely reason they locked up and broke off is because of the dissimilar metals (steel bolt, aluminum frame).

Go buy a small set of left handed drills and an easy out kit.

And its about an inch of bolt on the inside of both.

I have never successfully been able to get a deep bolt out with an easy out or left handed drill. I usually end up with broken drill bits and easy outs inside the broken bolt lol

Yea I thought about the left handed drill bits just don't want to mess anything up. But if that's what it comes down to will give it a shot

You can't gorilla fist it. It takes some finesse.

If the bolt is hardened (black oxide) or stainless steel, you can forget about drilling it out. You can only do that with mild steel fasteners. If the bolt broke right at the surface, you can take a dremel and grind a slot across the face, just big enough to fit a flat blade screw driver in.

Sounds like the bolt is broken in some depth inside the threaded hole, so the above trick is out. Can you get at the back side? If so and the bolt protrudes out the back, you might be able to work at it from behind.

I've had mixed results with these:



They got them at home depot. Some grade 8 large bolts took less than 5 mins. Some smaller softer bolts didnt do anything but chew the bolt up and then was forced to move to the left handed drill bits and an easy out. If you havent broken an easy out before, I HIGHLY recommend you dont try one. Like lisiecki1 said, it is a very finesse procedure and once you snap it off in there you will be hating life. I recommend using a dremel with a speed adjustment to drill your initial pilot hole.
