THINK....He had NO issues till he went from 3.91s to 4.88s.I will stick by my gear change screwing with his combo.THINK about it.His combo wont support 4.88s.Told him that before he went that way.Pulling my 4.56s and putting in 4.30s.Will loan him my 4.56 spool and I will bet anyone any amount he will pull just over 6.000 without any issues with my 4.56s.I am so sure of this I will put a grand on the table.Guzzi Mark
