Thanks to Pault, he has lent me some Handlebar risers to trial on the bike, so i decided to put them on today.
Was quiet easy actually, firstly you have to remove the plastic around the bars which is 4 plastic grubs
2 screws under the bars
1 on top of the plastic (behind the key), i just realised i missed taking a photo of it.
and then it is a matter of unbolting the bars, putting the risers in, setting the bars to comfy and tightening the bars up, you may have to shift the brake line, but mine still had enough play that I didn't have to
i was able to fit the plastic back on, it is slightly offset where the key goes in, i am going to tack the rubber insert that goes in there if i like the risers, but the job took me a whole 30 mins start to finish!
