Mirrors

[Raven]

Hi all. For no good reason I decided to change the mirrors on my rockster. Purchased a swanky looking pair off ebay for what I thought was a fairly reasonable price. Advertisement claimed they would fit my bike but on trying to fit them found the stem diameter to be 10 mm and not 8mm as per oem items.
Is it possible to get a 10 to 8 mil adapter or is it possible to do a bodge job to get these damn things on? Had a 10 to 8 adapter but threads arent long enough to fit through handlebar housing.
Any ideas would be appreciated as I cant seem to find anything on line that would be suitable.
Thanks.

my recommendation, find yourself somebody with a lathe and get adapters done from stainless steel. Or get the threads at your mirrors milled down and new M8 threads cut onto them.

What Raven experienced sounded exactly like what I went through last two days. Bought a pair of nice mirrors from eBay (Taiwan) that claimed to fit the bike, and found out they were M10 instead of M8 on taking delivery. The shop was kind to ship 10-8 adapters on learning the prob. However, I did not think the adapters will help given the confined space in the mounts. Managed to find a machine shop to cut away the M10 thread, mill a M8 thread and attached it to the new mirrors, and mount them perfectly! Did not manage to find any shop willing to mill down the M10 thread and re-thread to M8, due to bent mirror stems that could not be held onto lathe machine readily.

Will post some pics if anyone is interested, on the modification and look of new mirrors, after I learn how to post them pics hereI

Went down a different road here. Purchased a pair of 10 to 8mm adapters but found these would not fit into the handlebar mounts.Got myself a long circular file and spent a couple of hours widening the mounting holes in the handlebars to accomodate the new adapters.
Tightened the whole deal up with some threadlock and its a done deal.
Have to say the new mirrors are an improvement on the oem ones looks wise but find that they vibrate more above 5000rpm.
With hindsight should have left well enough alone...

What you did was an option. Decided against it for I wanted to be able to fix back the original mirrors in the future, for whatever reasons. My new mirrors are clear at high speed / rpm. Since you have widened the screw holes in the mount for M10, maybe you want to try the mirrors I purchased? Build quality is worth the price of GBP99 for a carbon-fibre look pair.

Hey, thanks for that, they look really well. The stem appears to be long enough to see past your elbows also (unlike mine). Think I will invest in a pair of these. At GBP 39.00 also a hell of a lot cheaper than the equivalent wunderlich/rizoma items...
