I will go the 55800861as well it looks like a better fit than the 55800856, might leave the indicator where they are, got a link for the mirrors?
Raised seam will not be an issue, it is part of the molding process, in the seventies I worked in a tyre rebuilding factory and when moulding we used to cut most of the excess rubber off, some was missed.
Few things on my setup... I am going with plastic wherever I can.
Couple reasons:
1. I initially thought, why not do a cut out
steal tank (like from a BMW) and metal mirrors, but then (not being an engineer), thought, maybe plastic (not being conductive AND lighter) would be a better decision. I mean, sometimes I ride with fingerless or no gloves, making my conductive skin more susceptible.
2. (with the signals) - I may hide them in a
custom headlight cover (flat/smoked ABS) with custom drilled holes (or none - since it will be transparent smoked) org/stock ones instead of any splicing... the less wires "I" have to cut, the better. I'm going to make an assumption that with the
MIL Malfunction Indicator Lamp I got this last weekend, (regardless of historical, actionable or pending) mods like spliced wires could throw errors and I'd like not to have to deal with those until the bike's warranty is up and I can mod more knowing it's not covered anyway.
That said:
Signal mounted mirrors -
(only good "now" - (with the drag bars) - when I am sitting up at a light - bar buttons block - considering tidying the buttons now too)
Left Bar End Mirror -
(have not figured out the right grip since you can't mount inside the bar and twisting will throw it off - but I don't care, mirrors are minor as I ALWAYS twist and look)
Old Mirror hole caps
helps keep crap out of the ORG/stock holes and looks nicer
*The signal mirrors will likely disappear anyhow when I relocate them near the headlight behind a custom cover.
*The left bar end mirror is convex and works very well! - Another reason I went with a grip mounted version is so I would not have to cut the grip.
** you COULD mount one on the right and just set it up so when you let off the throttle (e.g. sitting at a light or slowing) it's useful, but meh, to each their own.
**on your consideration for clip-ons, I love clip-ons; however you'd have to run all your wiring externally and it would be below the tree bolts...
that's about as low as the clubman bars would sit - possibly lower.
Hope that helps.
