Frame Reinforcement - NO WELDS

I've seen too many Blastys that've been 12 o'clocked by people tryin to learn to wheelie and they either bend or crack the frame at the spots shown in the red circles. In fact, even if you gusset the frame, these will still be your Achilles Heal:

This is a fairly simple structural reinforcement that'll only take you about 1-2 hrs and will about double the strength of the frame at it's most vulnerable point. No welding necessary but if you've already cracked your frame then this is for you too. If you're a novice welder like I am, it'll not only strengthen your frame, but keep you from blowing holes in it when you try to repair it.

My first blaster was busted and poorly repaired when I got it, so I welded it with these "sleeves": check these out. While I had a friend out riding with me, he stood that frame on it's ass and bent the s#!t out of the 1/4" thick six-pack grab bar but the frame survived. That ought to be all the proof you need that this mod is definitely worth doing.

Another friend cracked his blasty in the same spot learning to wheely so I helped him fix it the same way a couple of months ago and then I got a new '05 frame with a blown engine and decided to do this as a pre-emptive repair.

Here's what you'll need:
  1. Sawzall or Jig saw with good metal cutting blade.
  2. Vise
  3. Hammer - Heavey Ball Peen or Lump Hammer preferred
  4. 16 in. of pipe with an ACTUAL outside diameter of 7/8"
  5. 1 in. "Leg Tips" from Home depot or Loews, etc.. (see pick in the thread below)
  6. File or grinder
  7. and (possibly) Wire wheel on a grinder or in your drill (you'll see why later)

First things first: Take off the rear plastics and grab bar and pull the frame plugs out of the back of your frame. SAVE THESE!

Next cut two 5 1/2" long pieces of pipe; these are your reinforcement sleeves. Bevel one end of each sleeve with a file (or grinder). You'll need to cut a relief slot down the length of ONE side of each as straight as possible

Be careful when you near the end of the cut, the pressure from the vise will pinch the blade of your Sawzall. If you get it to within a 1/16" and open the vise, the pressure relief should "pop" open the rest.:

Not so straight, I know

The reason for this relief slot is the fab seam along the inside of each frame tube. In the '05 frame I used for this DIY, they're along the outside wall (put your finger in and feel for them).


Take your sleeves and put the beveled end into the frame by hand. Match the relief slot to the seam by twisting the pipe until you feel the seam "click" into the slots;

Once they're both in, pound 'em home. If possible, use a piece of the pipe to set them about 3/4" further in than the ends of the frame and put your stock end caps back that you saved from step 1 and you're done:

As luck would have it, that worked on the first two jobs I mentioned but for this DIY, not so much I:I :

If the sleeves begin to get mashed and distorted, you should probably have used a bigger (heavier) hammer. You may also be hitting the weld from where the lower frame bars meet the one we're reinforcing. That's OK. Get them in at least past where that weld starts (remember the sleeve is 5 1/2 in. ;) and trim them off flush with the frame:

Get those " 1in. Leg Tips" you picked up from The Home depot and modify them (I used a Dremel) so they go around the grab bar mtg. bracket. Be careful to only go as deep as you need so the caps stay on.

Each is slightly different so modify accordingly:

Pop 'em on and put back the grab bar and she's all done I:I

Better than new and no one can ever tell. Even if you've already PC'd that awesome build you've spent months on and mucho denaro, you can still protect your investment.

Oh! That Wire wheel I mentioned...

If you happen to have a donor corpse laying around, the skinny riser frame members (indicated in red below) are the perfect size for the sleeves. Just chop out the pieces you need and clean them up. You'll need to grind off the weldments that're all over the place and wire-wheel off the powder coat, but what the hell it was raining today and I need to get this thing out of my garage. So lightening it up an bit sure wouldn't hurt...

Thanks AWK! Yeah, idk if you use too many after market grab bars, but the longer they are, the more torque they put at those points. Also, the stock grab bars bend relatively easily. So they tend to absorb the damage.

For others out there think about the longer wrench when you need to break a nut loose - same idea. The friend I mentioned in the write-up who 12 o-clocked the thing, bent the rack instead that time I:I

Good Idea bro !!!! I would suggest to anyone for easier installation of the stiffeners , lubricate the holes innthe frame with a dry graphite lubricant , and put the sleeves in the freezer overnight before you install them , they will slide right in .

AWESOME suggestion Blastard! Prob doesn't even need to be over night either. Metal conducts so well that I'll bet an hour would be plenty I:I

my old frame was like this idk how it happened. I bought it and i always stay off grab bar never even touched it well one day i grab the grab bar and it just bent down and the frame was broken where he mentioned i think it was cracked when i bought it and a friend broke it and didnt tell lmao. Well i go it welded but bought i diff frame becuase i dont want one withe a weld other then gussets later on.

Long story short when i get my frame back from paint i will do this.
 
Invisible Gusset - No Welding

For anyone who doubts that this mod is worth the time/trouble, check out what my brother-in-law did when we went riding last weekend. I knew he was gonna 12 o'clock it 'cause he wouldn't get off his fat ass.

Just sayin... I'm sofa king glad I did this mod to the blasty b4 I let someone else ride it. 8-|
 
damn, idk how mine even happened it broke and i have never even hit grab bar on a blaster Wheeling. i think mine was cracked then maybe one of my bigger friends broke it while leaning on it and didnt tell???

that looks like he hit really damn hard
 
Yeah he hit hard. Wasn't even trying to wheelie. He just sits too far back and rides on his ass instead of his feet. We were going up a rocky trail and instead of being able to ride it out he hit a big rock and went right over backwards.
