[red98]

thanks for the replys...looks like were all thinking the same way....ive checked the clearences this morning and as mentioned by fazerider there not too far out,not been done before and bike now on 40,000 miles,results below

                inlet                                      exhaust
              0.11-0.20                                0.21-0.30

1              0.12                                        0.20
                0.15                                        0.20

2              0.11                                        0.20
                0.11                                        0.19

3              0.11                                        0.19
                0.11                                        0.19

4              0.12                                          0.18
                0.13                                          0.18

i could go up a size (0.05)which would put me in the middle of recomended clearences (haynes manual) or go up two sizes which would put me at the top end......or the third option leave as is ......iam just on my way to local yam dealer to see what they think and also to pick up some new plug caps.....will post there answer later :rolleyes
