Wouldn't attempt. The thing is I'm the type of guy that hears a squeak or knock I drive to the shop. What is it? I ask It that. They tell me. Order it and call me when in. I say. So wouldn't attempt. I know I can put more pressure in the flare which will "fix/bandaid" it. It's only the one gear. At the moment. So I'm thinking whilst it's ok I'll look for a good reco/2nd and spec it up. I've got sct flash and xcal4. So tuning isn't a drama. So thinking change shaft. I don't want to spend heaps. Just the minimum plus 20% to cover the horses. Sent from my iPhone using Tapatalk
