Had a similar problem with a bike dealer yrs ago.
Bruv bought an XS 1100 Yamaha.
Found several faults which were obvious MOT failures,but bike came with a 12 month ticket.
Dealer disputed all counts,despite threats of trading standards etc.
Resolved issue quite easily.
A visit to the premises ...

If it's hot,try tee shirt,cargo shorts and flip flops.
Dead comfy,keeps you cool.
Just don't fall off or crash.
Works for me.
Now we're gonna get all the safety lectures about acting irresponsibly.
But it's my choice,my life,and I don't give a stuff what anyone else thinks.

My issue's been in the post for over a week,or has the postie nicked it!!!

Kriega tailpacks are brilliant once you get used to the straps.Sometimes just bungee em on to rear seat or tank.Have used US20 and US10 for years and still waterproof.Ideal for weekend trips when not camping.Use R20 rucksack as well when mountain biking.Carries hydration bladder and miles more comfy ...
