Maybe a google search would reveal some comments from engineers. I would imagine that the location of the holes has a lot to do with the integrity of the bars.
When i compared my stock ones with the ones i drilled they are about the same thickness. Be careful when drilling as the drill bit tends to dance around. I just punched it and went easy. As for getting the right placement i grabbed a piece of paper and molded it to the top control switch and then brought it over to the bar and marked the spot. Just like thrillseeker said.Ryan Stecken said:the what i was thinking of.i guess alumium bars are also a no go.are pre drilled bars thicker steel ones or the same as the undrilled ones?
i got a drilled one at home so i can spot the area easily where to drill but i cant use that bar cuz i would need to get a longer braking hose..
Thanks for the insight!!xb33bsa said:the center hole between the clamps could be of concern if it was too large and the bars had rubber insulted clamp posts this would allow the type of movement that could lead to fatigue cracking
but if the bars are solidly mounted the center hole can be safely large
the ones on the end really arent a concern at standard type size just don't go crazy oversize
