Sorry, me again! I enjoyed the CL160/175 guide, although it concentrated more on the 160 and earlier 175 spine frame models of course, for which saying they were fitted with a sump guard was correct, unlike the K3 onwards which had a semi-cradle frame and never had sump guards as far as I know, also of course a slightly different engine being more upright. I often wonder what happened to the K1 and K2 models though; you’d have thought there would have been some knowing how Honda worked with their models but I’ve never seen a trace of either model in any listings. Thank you to Richard Pitman for reminding me about the cam-chain link originally being a split link, how silly of me to forget that as I must have handled hundreds of the things in my time (as I recall people used to also use them on the 400/4 cam-chain and no doubt the 350/4 as well but that was probably a bit more risky). As he mentions though of course replacement cam-chains tend to be endless with originals long obsolete, so if a new camchain is needed then it would have to be a rivet type and without the different cam arrangement on the 200 engine. Maybe the tool I invested in will come in useful after all.
