  1. As we all know getting brand new pistons for the xj900f can be very hard. But over the years with trail and error I have found some available now.. You will find the xj900f standard bore is 69mm The Suzki 850 over sized is 70mm and the dome is 1mm taller.. I have designed and built my own Trike and the 1mm taller dome makes more hp the faster you go... The higher speeds means you will need racing oil... Please be careful. Thanks
  2. Have any riders know where I could get hold of all the engine bearings from need all the shells as well not to sure what colour they are maybe black Ian
  3. Hi all Yamaha XJ900f riders Sorry to say last month I commented on XT225 pistons would fit the XJ900f This is not quite right The XT piston is a flat top and needs to be domed But After many months looking on the net I have found the Suzuki GS850 piston are Perfect for your rebuilds But you will have to have Cylinders rebored I have gone for the 70mm Have fun be safe
  4. Hi mate it might be worth having a chat with traffic police he might be able to chase it with engine and frame numbers
  5. Dear NEO Merry Christmas Just to let you know that after months of looking I've found the XT225 pistons will fit the XJ900f Ian
  6. After months of looking online, I have at last found New Engine Pistons which are for the Yamaha XT225 70mm which means they will be over sized from the standard XJ But will need to check Top of the piston to Gudgeon Pin which needs to be 16mm Hope this helps
  7. Dear NEO Thank you for your help but those other sites said they were Discontinued Ian
  8. NEO I've just looked on the site you mentioned and it looks like they don't sell them or cant get a price up
  9. Thank you so much for your help I've just found your reply... Thanks again x

    Hi all Ive just built an xj900f Trike Any ideas where I can get a set of engine pistons .5 oversize so I can rebuild the spare engine Ian Hi all Ivejust built an xj900f Trike Any ideas where I can get a set of engine pistons .5 oversize so I can rebuild the spare engine Ian Chedd YICS You can pick up on Ebay or adjust 1 carb at a time using the same vacuum clock to do all 4
  12. Hi all With regarding xvs 125 give a little more poke When I was 16 on my first moped that would also do 70- 75 on a good day My 125 would do about 110ish You will be able to find out whether it's restricted by final drive sprockets carb inlet size main jets needle height Exhaust But you must do everything not just one as doing just 1 will make the bike run lean then seize or blow up... If you have the money then get a big bore kit x lol maybe you should pop down your local tire garage and ask them to use an air wrench or a 6ft bar on the end and lightly tap the socket with a hammer to crack the seal

  20. Just an Idea Check the pump first But if won't start when hot could be an electric problem or Mixture But should be careful with this if it runs to lean for too long it will seize up
  21. It sounds like the selector forks or dog ends on the gears. Or maybe the pilot error lol They are online as Colchester Bearings or Pola Bearings they should be able to help
