Without being disrespectful to the OP, not everybody has those skills, also having parted with £2K of his hard earned money you would expect it to be done for him. Depending on your disposition it's events like this that can set off other personal issues.TBH, I'd sort it myself, it's just gear shifting. But that's me, I know I do a better job than a shop would. I generally pull shop bought bikes to bits before I ride them, and put them back together properly. But I'm just weird.
