    I thought it would be easier to put the photos into one thread for Megawatt's bracket and see how we get on.
    If anyone else has any valid suggestions then feel free to post.

    First job is to modify the mounting hole positions to a 59mm pitch. I simply used a drill to pull the holes closer together.
    [​IMG]

    I won't name the position of the rear set, but you can see which holes I used.
    I spaced the rear set out with 6mm nuts on the bracket, but had to remove the brake switch assy as it caught on the fairing.
    You can also see the extra bit needed to hold the heatshield cover.
    [​IMG]

    This shows the rear set fitted to the centre holes of the rear set as they are the only ones that allowed me to keep the peg horizontal, although I did have to made some adjustment in the bracket to get it to fit without spacers.
    [​IMG]

    Here you can see 3 mods I did to get it to fit on the centre holes. A small hole drilled to accept a pin on the set, a half moon groove so it sat flush and a notch for the brake pedal spring to clear the bracket.
    [​IMG]

    After all that, the bugger didn't clear the fairing, even with the extra spacing.
    [​IMG]

    Same mounting, different angle.
    You would need at leat a 20mm spacing to get clearance of the fairing.
    [​IMG]

    Next mounting position. I believe that this is the lowest & furthest back.
    No need to mod to get this to fit. I also refitted the brake switch at this point, there's just enough reach on the cable too.
    [​IMG]

    On the bike, clearance wise, these were the best mounting points. Hows that for clearance behind the brake pedal spring :D
    It does add one hell of an angle to the brake pedal though.
    [​IMG]

    I think a little more clearance upwards would help, say 5mm up from the last photo as the brake switch bracket will rub on the fairing.

    I also stood on the peg, it bent a little, but took my weight.

    And I couldn't try the forwardmost holes due to lack of clearance behind the rear set (the only way around this would be to have a second bracket purely for those mounting points).

    I have also yet to try the left side.

    Do you reckon all the holes should be 59mm apart or just the untapped ones.

    Well that's the strangest thing. They should all be the same 59mm, but I only had to adjust the untapped holes.

    The lowest mounting points in the last photo seem to be the best position on that side of the bike due to clearance problems, although it would be interesting to see how it would fit in the front holes. A different bracket would be needed though.

    You can probably see how the angle of the rear set would vary depending on which holes were used and the problem with clearance at the back of the fairing when the rearset is at the original angle on the plate.

    I should also rephrase that the 6mm plate flexed rather than bent when it took my weight (14st 3lbs today, had a big lunch). A pair of these I reckon would be ok for most mortals.

    The heatshield bracket should be an easy fit. I can rivet on a small length of ally to line up with the hole. And having looked at the left side (still untested so far) I really can't see there being a problem other than the reach to the gear shift, but I'll come to that when I tet it on that side as it's dark now.

    I can make spacers for clearance. What thickness would be optimum.?

    Sorry for the delay. Brake pads started grinding on the car last night, so I've spent the morning getting that sorted.

    You'd be looking at least a 30mm offset, and having used nuts and long bolts to space it out it sticks out a mile and could cause problems with the load bearing on the bolts.
    [​IMG]

    There are a lot of things sticking out from the back of the right hand reaset as you can see in the pic. This is what's causing issues with the other mounting points on the bracket.
    I would definately stick with 6mm Ally as any more would make the brake switch bracket catch the fairing and you would need too much spacing to go over the outside of the fairing.
    [​IMG]

    It's really tricky to find a solution where a single bracket could have all those variations, so I've marked the ones that work on the right hand side as it is.
    [​IMG]

    This is an example of what would be required to get the front positions working.
    I've photoshoped the previous image and cut it down to how I think it should look using my original measurements which were around 20mm back & 30mm down (I'll double check that later as all these images are slowing my PC right down).
    [​IMG]

    That's as much as I can do on the right side. I'm gonna head back out and make a start on the left side.

    On to the left side. Much more straight forward.
    The only 2 issues here are that the heel guard catches against the swingarm in any positions further back than in the photo.
    [​IMG]

    And lack of reach to the pedal unless in the forward position. In fact it felt better when I angled the set back to it's original angle.
    (obviously no bottom hole there to line up with the bolt though ).
    [​IMG]


    My findings are, that I think the safest bet is to limit the amount that you go down & back to the maximum on the right side (around 20mm back & 30mm down), which will also allow for pedal reach on the left side.
    Big drops appear to be a no no on this bike, unless modifying the right hand lower side fairing and finding a longer gear pedal.

    Good work, the thing I got was that using the thicker bit of plastic helped mine as it acts as a spacer to move everything out to clear the plastic
    [​IMG]
    What size of feet are you its just that i dont have a problem reaching the gear selector with mine 50mm down and 30mm back and i have a size 11.5 boot.

    I'm around the same size, but when using the same holes as in your photo my left foot ached a little after trying to reach the gear lever, which defeats the point of lowering the pegs, so I found the closest position more comfortable.

    It could be one of those subjective things, but I know which position is best for me, the closest one on the bracket.

    So the most important question is does it make a difference? Is it more comfy?

    Interestingly enough, I actually don't know.
    Between working, test fitting the brackets and looking after the kids, I never managed to get the bike out and try it for size, but I'd be happy to try propely with 2 smaller ones on.

    Can you guys do me a drawing each with dimensions to tell me the optimum positions for you. I can modify the brackets to suit with another position either side of optimum. I have priced up 5 sets of brackets that will be cut using a Flowjet cutter. Are we definite on the 59mm pitch for both of you?

    Can do, but im not sure when i will get a chance as i am going away with work. As soon as i get back then i can pull the one i made off and get the dimensions.

    Can you confirm pitch of bolt holes is 59mm or 60mm?

    Alan.
    Having had the caliper gauge out again, if you use 10mm ally then I can go 20mm back & 30mm down, which is fine for me. I know it doesn't sound much, but it's a safe option. And I confirm the pitch on mine is 59mm.

    Was there a threaded hole position that gave you that footrest position?

    No mate. I just manipulated the right hand rear set in to that position to check clearance as I can't do it on the bracket you sent due to lack of clearance over the brake switch bracket.

    This is the bracket for the left hand rearset or the brake pedal one and you can see the cuts i had to make to clear everything.

    [​IMG]

    Pitch wise i just made the holes that little bit bigger and then made a locking bar to act like a washer i see pic below of it fitted

    If you can send me a drawing and /or a template with your ideal settings, I will put em with Muffkings and get the thicker ones cut out. Whadya reckon 8 or 10mm?
