Hi guys new to the forum and this bike. Havent bought a service manual yet, can anyone tell me if there is a valve or shim adjustment done on the first service as per the manual?
Your Owners Manual has a chart showing the maintenance timings, so have a read.
My answer would be 'not required' at the 600 M/1000 km first service.
My GSX-S1000 did not have that requirement. The only bike that I owned where this was suggested was the original year Bandit 1250 where Suzuki suggested it rather than mandated it.
If you Dealer is suggesting this, it's a con job on you.
