Hello, My XS2 has done some 1k miles since being restored and runs well. The electric start has never worked. However I did replace all the bendix bits behind the clutch but the started motor seem to make a harsh rattle. So I finally found a replacement starter and decided to replace it...

Looking to see if there are any x650b exhaust available the 1975 one. I know there are some good reproduction ones for the xs1/2. I cannot find anything for the xs650B. Not original looking ones anyway. Are there any? Ta Nairb

I know this is a difficult thing to work out without hearing it but ......... Are the xs2 engine a bit noisy compared to say a honda 450 twin?. My honda cl450 sits there with a quiet rustle of timing chain and tappets. The xs2 seems to clatter a bit and the tappets seem noisy by comparison...

Does anybody recommend a battery for a XS2. The first with the estart. Here in the UK there are exide/Yuasa and others. I would like to try a motobatt but I am not to sure. Has anybody found one that lasts with that demanding estart. Ta Nairb

I have finally re-commissioned the xs2 and had the engine running. Like a lot restorations of old bikes the real faults that stopped it all those years ago surface. The engine starts well off the kick start and does run evenly on the choke for a short while. I should point out that the engine...

Finally put the fuel taps back on the xs2 tank. They have been rebuilt with new seals. Put some petrol in to test if it all still holds fuel. Thought I had put both taps to off. That is both taps pointing in the same direction. NO - one tap was letting fuel thru - and it was on "reserve"...

Ok, I have finally put all of the xs2 back together – that is all the electrics are finally connected up and all the control cables fitted. Fitted a new set of starter gears/spring behind the clutch. As the started system was known to be not working or making a noise. Having never actually...

Hello, The last of the known faults is the front brake. I thought I might as well try it with some fresh brake fluid. Nothing dooin. No fluid getting thru. Decided to take it apart and check the seals. Its stood for years and the MC had been all clogged up. It came apart quite easily...

reading on the forum it seems there can be 2 sizes for the clutch nut.... that great fat nut that holds it all on. I have measured the size of the nut on my xs2 and its 29mm I think. Do all xs2's have the same size nut?. Or is it a case of you get what your given. I only have 27mm and 30 mm...

I knew when I purchased the xs2 bike that the electric starter system was not working to well and needed fixing. Well that time has come. I have sorted the forks/front brake/cables that were frayed/petrol taps cleaned/new tyres fitted/ etc and could not longer put off the starter issue. I...

Thought I might as well change the front brake hose (x2) on the xs2 during its rebuild. Could be done at any time I guess but while its apart .... I have looked up these brake hoses on the web (mikesxs etc) and the new hoses seem to come with protective springs around the hoses. Did the...

Hi, Those inlet manifold covers on the xs2 (see pic). Mine were rusty so I have cleaned them up a bit and now will have them plated to stop them rotting further. Does anybody know what the original finish was. Were they chrome? or some nickel plate. Ta Nairb

I pulled the front forks off the xs2. Its time to change the oil/fork seals I presume the seals are the originals. They come in 3 bits? Top metal ring, middle seal and bottom metal ring. I am replacing them with some ari seals. My question is do I still need to use the old metal rings and...

Hello, I am partway thru the restoration of a 72 xs2. Its time to get a few bits re-chromed. The bike is mostly complete and original and I wish to keep it as close to factory finish as reasonably possible. Those front fender bolts (x6) which hold the struts/stays on to the fender are the...

Anybody tried to take the rear shocks apart on a standard xs2. Can the top be un-screwed and then put back together. There are large hexagonal looking nuts at the top of the shocks.... must be there for a reason. On the old honda's I have worked on the rear shocks used collets which could...

Is there a picture out in the world showing the cable routing for the wiring on an XS2. I have it OK I think from the head lamp but it would be great if I could get the correct layout around the battery box etc. Thanks Nairb

question about the size of an inner tube. I am looking to put a 4.00-18 on the rear of an XS2 yamaha. There are masses of inner tubes for a 4.10-18 but very few for a 4.00-18 (here in the uk) Does any body know if I can put a 4.10 inner tube in a 4.00 tyre..... of do I have to get a 3.50/3.60...

Been looking for new tires/tyres for an 1971/72 xs2. I did look at some metzelers But the question is what speed rating is best for an old 650 twin. A ME 11 3.60 -19 52S on the front and... a ME 77 4.00-18 64 S on the rear The S rate is for a max speed of 112 (mph) with 52 being for...

I need to get some new tyres for my new toy... an xs2. The ones on the bike Are 4.10/19 front 4.25/18 rear The Haynes manual says 3.5/19 front 4.0/18 rear. I have Metzelers on my other bikes.(suzi gt750, cl450,cb550) and they are fine. Anybody tried Metzelers on their XS2 and which...

I finally have my hands on an XS2 650. Complete and more or less running. It needs a bit of effort to get it back on the road. New engine oil and filters will be a start..... The size of the oil drain bolt was a surprise. And I need to get a spanner/socket to get the think off. Just to...
