Posted May 16, 201113 yr Hi, Having rebuilt a 1988 tzr 125 which had been stored for 13yrs I have one question, which grade plug should I use now that it has a fully working ypvs, so is now a full power model? The workshop manual states use either a B8ES or B9ES, but which would be best? I know the standard restricted model uses a B8ES but should I use a B9Es now its full power? I am currrently using a B8ES and the plug is a nice light brown / dark tan colour which I believe is a good colour. Any suggestions??? Thanks.

With 9's as an option for more spirited riders.
