[QUOTE] It was running fine and wasn't making any untoward noises, so I didn't suspect a thing.[/QUOTE] Hog phoned me last night with the full SP. Sounds a PITA but not the end of the world, especially as he can flog those DG heads to pay for it. Like you, I'm amazed it ran at all, let alone as sweetly and quietly and well as it did, with all that. Apart from the gearbox hassle, it felt like a nice well-sorted RD to me. Strokers, eh? Well, that was an educational ShiteOldBike weekend, all in all. Lessons learned: 1. Strokers are always trouble. 2. Any bike that's running perfectly will conk out the moment you sell it (XS650). 3. Send word that you're messing with SOBs and half of ukrm will turn out, just to point and laugh.
