Modifying 550 frame
« on: April 16, 2014, 03:54:45 PM »
I have a 74 550 frame that I want to detab and modify the seat frame. I know, I know? I'm ruining a classic frame blah blah blah. Once you can get over that, got any suggestions? I'll be adding a hoop with a brace and a flat seat. I'll be moving the battery under the seat and removing the center stand as well. I'll be adding some reinforcements to the triangle too. Rear sets will be added too. I want to trim off what I can before powder coating.

If you've got pictures, diagrams, ect, they would be greatly appreciated!

Jordan,

Just to help clarify your question, by adding a "flat seat," will you be using a brat-style seat (flat from end to end)?  If so, where do you intend to "mov[e] the batter under the seat" since there's no speed hump to hide one under?  Are you trying to completely open up the triangle (hide all electronics, battery, etc.)?

Don,

Yea, I'm planning on mounting the seat like a brat seat with a pan under it to hold the electronics and a trough above the carbs to hold one of those little overpriced batteries. Am I crazy?

No, you can sandwich a small Ballistic or similar lithium battery in a box under the seat.  Your electronics tray will most likely be located further to the rear, partially above the carbs and above the triangle.  It will not be completely hidden by the frame rails, since you will need enough depth to fit the battery in sideways.  You will need about 2.4 inches of depth for the battery and any strap/fixture to hold it in place.  The only thing you may want to think about is where to mount your regulator/recitfier (assuming you are going with a modern solid state unit).  I would recommend against mounting this in a such a small tight space, since it will have no fresh air to cool and you can end up frying the unit.  I've seen people mount them on the bottom of their electronics tray so the cooling fins are exposed to fresh air, but this might render it visible.

Have you started welding your bracing, yet, or are you too busy with your cut-off wheel detabbing the frame?

Neither yet, I won't be working on the frame for at least a month. The wedding is fast approaching and my new wife will be leaving in August for PA. After that, it's on!

Ok, so you have a month to map out your frame mods.  I'm looking forward to seeing some progress in August, damnit!

Make sure you put an upsweep in that rear hoop. I didnt and ended up with only 2.5" between the top of the tire and bottom of the frame!

Seriously, you moving To the "Right" coast? How exciting. There's some awfully good roads to ride in that neck of the woods, western side of PA, upstate NY, and on into New England. Better trade in your t-shirts, shorts and flip-flops for some fleece and turtlenecks.

The big upside is the beaches. The water actually gets warm! No sea lions, far fewer sharks, and the lobsters out here are large and good. A pretty decent trade-off. We will have to pry Don loose for an extended Fall leaf-peeper ride!

Cal,  can't wait to ride out there. I do love our sharks and seals here though. Don will have to come visit!

Whereabouts in Penn are you moving to?  Philly, Harrisburg, Pittsburg?  You will definitely get to see the seasons change.  Soak up some sunshine for the next year.  You will need your Vitamin D!  I have not been riding on the Right Coast.  I could go for that, as long as it's not snowing!

Seriously, you moving To the "Right" coast? How exciting. There's some awfully good roads to ride in that neck of the woods, western side of PA, upstate NY, and on into New England. Better trade in your t-shirts, shorts and flip-flops for some fleece and turtlenecks.

The big upside is the beaches. The water actually gets warm! No sea lions, far fewer sharks, and the lobsters out here are large and good. A pretty decent trade-off. We will have to pry Don loose for an extended Fall leaf-peeper ride!

Cal,  can't wait to ride out there. I do love our sharks and seals here though. Don will have to come visit!

Whereabouts in Penn are you moving to?  Philly, Harrisburg, Pittsburg?  You will definitely get to see the seasons change.  Soak up some sunshine for the next year.  You will need your Vitamin D!  I have not been riding on the Right Coast.  I could go for that, as long as it's not snowing!


We'll be an hour east of Pittsburg in a small suburb.  We'll definitely be making trips to the coast to meet up with family in CT and NY.

I'll email Ian Halcott and see if he has any pics of The Thorn built by Twinline. The frame is heavily braced and detabbed.

That'd be awesome Don!

Cal, those are just detabbed and clean triangles, I need a color scheme too but not in any rush as I'll need to do a lot of cutting and welding before powdercoat. I'm not PC'ing it black, that's for sure!

I emailed Ian LATE last night. I'm not sure if he's going to Corsa Moto Classico this weekend at Willow Springs (right next door to APE). I'll let you know if he emails me any pics.

This looks interesting. I'm still searching on here, since there is so much to look at, I like that raw finish look. It is something I plan on doing since black powder coat is over done.

I will have to follow up on this.
