there's a company on ebay that sells carb kits and they are based in Canada. first do a search as I have posted web based suppliers before and can't be arsed typing them out again!!

you need to get a manual. It will pay for itself in no time

sounds like pre-ignition. have you checked your ignition timings?

spped and sport has one Part Number Description Model Prefix On Hand Price Add Cart 1 1J7-25850-52-00 MSTR CYLINDER ASY XS750 D 1J7 1 $198.72 check part number against you parts list first

have you tried www.cmsnl.com based in holland www.motogrid.com american www.yamahatopdog.com american www.bikebandit .com american www.nwvintagecycleparts.com/ Its really no big deal getting stuff from usa especially when the pound is so strong at the moment. I've had to use these guy's for my xs400 resto.

good to hear you got it sorted, jobs like that drive me mad with fustration!!

To quote Shakespere..... 2D or not 2D that is the question.... I forget which way round, but one model had drum brakes and no starter motor the other disk front and electric start

as far as I know the xs360 and xs400D frames are the same. don't make the mistake of using heritage/custom models as their frames are different

the rubbers should be a tight fit on the shafts and secured by bolts. motogrid do them.

I'd get it on a rolling road dyno and get a fueling curve printed off. It will tell you what you need to do and save loads of time.

another tip i've remembered, use a plastic waste pipe to hammer home the seal.

I haven't got a YB but check for a allen bolt at the bottom of the sliders. you need to break them fast or they'll turn and then you have to make a tool to hold a nut the other side ( a very long tool).

I use a tyre lever and rag to stop any indents in the alloy and a LITTLE heat to soften the rubber. If its really low drill a hole and screw in a self tapper for some thing to pull up on. I'm assuming you have taken off the stantions.

YPVS is solinoid operated via electronics and is used to enhance low rpm ie shortens the exhaust length. It can stick but the whirring you hear is the checking system.

you're correct in assuming the pipe seals are to blame as that will produce the backfiring you are experiencing. You should have a gasket there, but it may be compressed and does look at first to be part of the cylinder head. try cleaning around the exaust port and check for a gasket (they can be metal copper or steel concertina shape) hope that helps, if you seal the exhaust and it still backfires, then timing or fuel mix is to blame.

erm..no thimble full at most there's no seal there, maybe try tightening the case bolts. 8mm = 2.0 - 2.4 lb ft 6mm = 0.8 - 1.2 lb ft ps I am talking about the left side of the bike (as you sit on it) as the engine only takes 2 litres (2.3 with new oil filter) so hopefully your not removing the clutch side?

this a great gathering organised by the LE velo club. Its situated off the east Lancs road. Lots of different bikes attend and there is a great (free)museum housing one of the largest steam engine winders in the UK. 11am to 4pm directions here

LT is left timing for the valves on that side RT is the right timing for the valves on the right make sure the piston is at TDC by removing the sparkies and feeling compression with your thumb. inlet (carb side) is 0.08 - 0.12 mm exhaust 0.16 - 0.20mm A little oil does come out and my engine has only 2k since rebuild

check fuel flow from tank and it is venting (replacing the space left by the fuel with air) then check float heights in each carb

you obviously got too much time on your hands. Very nice bikes, hats off to you!!

great, that wheel is off a custom model

Mr Cadbury and Miss Rowntree met on a Double Decker, it was After Eight. She was from Quality Street , he was a Fisherman's Friend. On the way they stopped at a Yorkie Bar, he had a Rum and Butter, she had a Wine Gum. He asked her name, "Polo, I'm the one with the hole" she said. "I'm the one with the nuts," he thought! Then he touched her Milky Way. They checked in to a hotel, and went straight to the bedroom. Mr Cadbury turned out the light for a bit of Black Magic. It wasn't long before he slipped his hand into her Snickers and felt her Cream Egg. He fondled her Flap Jacks then he showed her his Curly Wurly and Tic Tacs. Miss Rowntree wasn't keen to have any Jelly Babies, so she let him take a trip down Bourneville Boulevard via her Party Ring. He was pleased as he always fancied a bit of Fudge. It was a magic moment as she let out a scream of Turkish Delight. When he pulled out, his fun size Mars Bar it felt a bit Crunchie. She wanted more, but he needed Time Out, however, he noticed her Pink Wafers looked very appetizing. He did a Twirl, had a Picnic in her Sherbet Dip and finished off by giving her a Gob Stopper! Unfortunately, Mr Cadbury then had to go home to his wife, Caramel. Sadly,3 days later his Magnum lolly started to drip. It turned out Miss Rowntree had been with Bertie Basset who had Allsorts!!!

take off your spark plug and it should stink of fuel. this will also bore wash your oil and wear your engine quicker.

Welcome to the forum

I'd check the earthing lead from engine to battery and also check live connections from battery via starter solinoid to starter. ensure the battery is fully charged. all else fails your starter brushes are worn. Get a manual for the bike, this will pay for itself in no time
