Hi all, I am using a pair of VM34 carbs at the moment on my 77D but I am thinking of going back to linked carbs. What were the best carbs that Yamaha used on the XS650's? Looking for recommendations.

Hi all, does anyone have experience of the Heiden tuning electronic ignition. I have used Pamco in the past and they were great but the Heiden one I am using on my latest XS I am not sure about. Definitely doesn't like starting on the kick start and not too happy when cold and on choke. Runs...

Hi all, a carb question for the massed brains of the group. Engine rebored, new crank bearings, new everything really. New pair of VM34 carbs, semi open exhausts and ram air filters. Runs quite nicely once you are moving but just won't idle very well. If I come back from a ride the revs take off...

Hi all, desperately seeking a lower yoke and steering tube for my 1977 XS650D. After a total rebuild I have done around 50 miles and it runs pretty well but the steering is a bit out of line. I have just stripped it down again and the lower yoke has a slight bend in it. Does anyone have a spare...

Hi all, I fitted a pair of 'progressive' springs when I rebuilt the forks on my 77D. Fork oil level is as recommended in the manual. Just started to do a few miles and I have noticed that the forks top out on the recoil with a bit of a bang. Has anyone else had similar problems? If you did, what...

Hi all, On the first 2 XS engines I did a 100% re-build on there were no leaks at all. I have just finished the third one and started doing some miles on it and it leaks like a sieve. I have taken the engine out of the frame and stripped the top end to replace all the seals and gaskets. I was...

Hi all, I have just removed my pilot jets to clean the carbs. The new jets I have bought are the VM22/210 type, which are correct for a 77D. The old ones that came out of the carb have no air bleed holes at all so they can't be BS30/96 or VM22/210. Has anyone ever seen pilot jets with no air...

Hi all, I am having trouble setting up my new PWK32 carbs. I think that the slides may not be closing properly. Has anyone found a source for stronger springs. Many thanks.

Hi all, I have just bought a pair of the Keihin PWK32 carbs from the XS650 shop. The bike starts straight away which is good but I am looking for a 'best practice' option for synching the carbs. I have synched by measuring and synched by vacuum gauge but their is a lot of fluctuation on the...

Hi all, I have a question for the forum. I am rebuilding my engine and refitted the pistons, barrels and head this afternoon. I remember putting the o rings on the liners and pushing them up but I was going to push them into the groove when I had the barrels sitting on the engine. I forgot that...

Hi all, I have just been cleaning up my valves. The seats are good, I just gave them a little clean with fine grinding paste. My main concern is the valve faces, or heads. On a couple of them I inadvertently cleaned off some of the black face coating down to shiny steel. Are the valves still...

Hi all, I am rebuilding a 650D and want to use a Pamco ignition system. I know that they are not made anymore but was wondering if there is any stock still floating around. I have used Pamco on 3 other XS650's and have only good experiences so want to stick with what I know is good. Many thanks...

Hi all, Does anyone know if there is anywhere on line to download a copy of the XS650D parts book. CMSNL have it on their site to use but I would like to download and print off a copy so I can mark off bits I need as I strip the engine. Many thanks. Tim.

Hi all, Just got myself another XS, an XS650D this time. Last project before I retire I think. I want to fit a Pamco ignition but I hear rumours that Pamco ignitions are no longer available. Is this true? Tim.

Hi all, looking for a frame for sale in the UK. Preferably mid 70's and straight. Many thanks.

Are heads and barrels interchangeable between 533 and 447 engines?

Hi all, I bought a new kickstart lever from a supplier over here and it hits the brake lever as it goes down. I haven't got an old one to compare shapes and sizes. Has anyone had a similar problem? Thank you. Tim.

Hi all, I am re-building my engine on a very tight budget as my future ex wife has taken almost everything except my vital organs. My question is, can I re-use the old clutch plates. All 7 measure up at about 2.9mm. The engine was sat for a long time and the friction plates were lightly stuck...
