On Saturday I thought I'd start the project ('62GF with different engine / front wheel) and check the timing. Selected 3rd gear, pushed back onto the roller starter, pressed starter switch and eased the clutch out slooowly. Nothing - blown 13A fuse on the mains-powered starter. Replaced that and tried again - and again and again... After 4 fuses I gave up. OK, so it's cold and turning over is harder, but these starters are supposed to start any bike and 13A @ 230V is around 3bhp. So I called my son and he came over on Sunday.
Same process, though with an extra pair of hands we were able to get it turning over decompressed before dumping the decompressors. Fired up straight away. Checked the ign timing and it was running fine. My son therefore tried it on the private road outside my workshop. Front wheel was pawing the air on full throttle in first - very encouraging. Even more so because my primary drive means the gearing is way too high (or low in engineering terms) - 1st gear is around where 2nd should be. Even better was when it stalled - a quick kick on the kickstarter and it was alive again. I was so amazed (given the starting issues I've struggled with on this bike) that I switched it off and tried it again. Started immediately. Things are really looking up. Wonder if it'll now start from cold on the kickstarter?
So I'm looking for a 49t rear sprocket (for FWH). There's none on ebay, not even a plain sprocket I could weld on. Anyone in UK have one they would sell?
