  1. yes thats alex mate
  2. its the sound of air being forced back out of the inlet tract, normally there would be reeds in there and the motor would be turning much faster...so seating the reeds and no blowback
  3. any race bike or high peformance engine, from all manufacturers would be devoid of this groove, the only bike i saw it on was a later model DTR, not sure about the DTRE but the numbers on the casting will tell the tale
  4. the squish band is the band around the combustion area that has a very small gap between the piston and the cylinder head...when the piston is at TDC, some of them have this convoluted groove in them (i know not why) the best one to go for is the one without this groove IMO
  5. you can have one kev but it'll cost ya, see the top of the screen thre's a 'subscriptions' button. All the flag wavers have pressed this ere button!
  6. Have a great day drewpy
  7. hmm could be a crank seal issue?
  8. in the past i have rounded off the hexagon on the bowl because i used open ended or 12 point ring spanners...i learned my lesson and now i would use a 6 sided socket commonly found with 1/4" drive
  9. blocked pilot jet? how does it seem with choke?
  10. yeah i'm thinking of the explosion risk, what if there were a spark inside...I figured rightly or wrongly that something that couldnt be ignited with a match...ie not vapourising...would be safer, I would be concered with using thinners unless it passed the lighted match test but hey I'm no expert so how is the petcock fixed to the tank? pehaps for safetys sake stick with water (de ionised) and then rinse out and shake some WD40 about in there to prevent rusting?
  11. not sure about the petcock...do you mean to remove it from the tank or to strip the thing down? also not sure about using water in the tank, how about using fish tank gravel and paraffin (kerosene) or WD40? I appreciate that you wouldnt want to use something too volatile but you can toss a lighted match into a container of kerosene and it will extinguish it wont it?...waddya think? i've never had to do this kind of work myself but if i were to go down this route i would prbably not use anything that would ignite by a lighted match............how volatile would laquer thinner be?...take care!
  12. ahh...saw the title and thought you had a nutter to deal with
  13. no mate mine works from good ole gravity seems a few YBR's also suffer from this!!
  14. what is it about yamaha fuel pumps and warm weather???!!!

  18. great stuff andy, look forward to seeing you progress with this
  19. Greetings Natalie post up a piccy then
  20. how come its the piston corey? is there good compression...i suppose theres no kicker on such a modern bike?
  21. dont blame you mate, i'd have done the same myself
  22. and the flywheel key, which only cost pennies????????
  23. nice one deon..., how you finding the beast then?
