if this was my bike i would be concerned.
i suggest checking everything that you can yourself. my list would be something like:
- tyres - condition and pressures. these need to be spot on for perfect handling.
- wheels for trueness - get each wheel up and spin them with a datum point against each rim
- wheel alignment - using two long straight edges or a laser if possible
- forks - straightness and damping action. i'd get them out and make sure that each of them is straight and that they feel and react the same when compressed by hand and let go
- yokes - i could only really perform a visual check on these as i don't have a jig to put them in but i'd be putting straight edges against them and assessing as best i could while the forks are out
- frame straightness - as best i can with my long straight edges
if it still handled oddly then i'd be putting it back to standard and moving it on!
as an aside i find it incredible that any owner spends (quite obviously some serious) money on suspension upgrades but doesn't know what pressures are in the tyres. even a cheap gauge is an absolutely essential piece of bike kit. it may not read perfectly accurately but at least allows for consistency. bike tyres are safety critical items!
is it clean enough?
