Just a pet project I'm working on. Trying to track down when the reinforcing gussets existed (behind the left rear cylinder stud). This chart shows what I've been able to determine so far. XS1/XS1B engine case revisions by serial number 1970 XS1 S650- 000101 - Rev-0 case, no reinforcing...

Found a Japanese Motorcyclist magazine, May 1969, on eBay. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F264365610598 The seller posted pictures of an article on the XS1 Proto, possibly spy pics. Snagged some copies from the listing. Cleaned-up, resized...

Picked this up years ago, thought it looked way better than the 74-83 buckets, and didn't realize it was from the early models until a thread on these early buckets came up a few months ago........Had a look, (in storage), and low and behold........ Had a squiz around ebay and saw another...

Hi knowledgeable XS fans, I am servicing my xs1. Removed the plate below the engine where the oil filter is. Found a loose hard rubber plate. It comes from the cam chain tensioner: just below the pinion that is pressed against the chain. I cannot figure how it was attached to the aluminium block...

I have a question about the jetting chart in the carb guide. The section for '70-73 shows two different pilot and mix settings. Am I reading this correctly that there were the settings specific for 70/71 (45P and 1 mix) and then 72/73 (42.5P and 3/4 mix)? Why the difference if so? Attached is...

Does anyone know about this product? http://www.ebay.com/itm/191028848114 I'm wondering if it can be used to fit an XS1 front drum brake to newer forks? I think I read somewhere it can be used, but the tab on the adapter would need to be shave down just a bit. Anyone out there with any...

Has anyone ever laced a xs1 front drum to a 74, 19" aluminum rim? Like the one on the back. I have the rims and the front drum brake so I'm looking for some direction of whether it can be done properly or I should just stick with the steel rim already on it?
