Lugs on handlebar gear, cut or drill?

I am changing the bars on the Blackbird for a set of Gilles raised
ones. However, I come to put the indicators and throttle back on and
they both have locator lugs, question is, do I chop thes off and let
friction hold the gear in place, or do I drill a new locator hole in
the new carbon fibre bars (and weaken them?) thoughts anyone?

Will the throttle spin on the bar without the locator lug in place?

Yes.

 

What he said. Also, the choke's a bastard on the other side.

Drill 'em.

Or without some alternative means of positive location, perhaps.

Do you? Drilled many carbon fibre bars?

 

What would you suggest?

Nope. I've not even drilled any steel ones; they still spin like a
bastard and would stop if the holes were there.

Are you saying drilling carbon fibre's a bit splintery? How the buggery
bollocks does anyone get anything done with the stuff?

 

I wouldn't drill the new bars.

Had some success in the past using aluminium grip strip.
This stuff comes in lengths about 3/8" wide and is punched/perforated to
give it a spike surface.
I *think* it came from B&Q and is sold for repair chair joints etc (wrap it
around mortise and stuff in tenon - or is it he other way 'round?)
Anyway, a short length wrapped round the bar allows the switch/throttle body
to grip without drilling a hole.

Holes not only weaken the bars but, still the angles are different, you'd be
hard pushed to get them in the right place first time.

What he said (sort of). Do not drill into the carbon bars.
Remove the locating peg and use some appropriately
placed double sided sticky tape betwixt throttle and bar.

Drilling a carbon bar is just asking for it.

It's a common thing on the 748-916-996-998 bikes to remove
the locator pegs out of the brake, clutch and switchgear
units (which includes the throttle) to make them less
cramped on the wrists.

I've done it myself and you won't have any problems at
all. If you're that paranoid, get some gaffa tape wrapped
round the bar to give the throttle something to bite into.

 

Haven't changed motorbike bars since 76. I drilled the bars to take the
lugs/pegs. They were steel bars.

S'ok, I compromised, as there is no choke I chopped the plastic lug
off the lhs, then decided as it was a bit critical (understatemen) on
the RHS, i wouild drill a small hole. It was then theyt turned out to
be carbon 'look' and were in fact steel!
(I am (obviously) no expert in the identification of carbon fibre)
The job is almost done, after getting the bastards *completely* the
wrong way around I have now got them in place, I must hold the record
for the most possible mistakes you can make on what should have been a
*simple* install. Now all I need are some new brake lines as the rhs
is now too short by a bastard inch.
(The clutch pipe could possibly do with replacing too,m but I might
just get away with that one.)

A scalpel for a square hole or a small as you can get it drill and open
out a round hole with a needle file spun in something like an electric
screwdriver or better still the proper dremel tool.

Go slow and fix the edges with a teensy weensy drop of penetrating
superglue.

I know because I have worked with the stuff.
