I’ve finally finished the GPz550A1 and have now started looking at the C15. Sadly, it would appear about 40% of it seems to have disappeared over the last 40 odd years, so it’ll be a longer project than I’d initially assumed. Also, of the engine bits that are left, it would appear that in the 20 years it was on the road, it had been thrashed mercilessly by every one of its owners who spent nothing on maintenance. I have to admit, it was my first bike and I was so poor I could afford to buy it, and didn’t spend much on it either. Ironically, I stripped it down back in 1984 in order to spend some money on it, but then I joined the RAF and the job stopped for 40 years! I’m restoring the engine first, and I’ll post some photos up when it’s done.
