Hi Guys, First time Poster, first time GS owner, love the bike but hate the "suzuki recommened Valve Clearance checks" every service. Doing 790 kms a week to and from work puts it in every 3 months or so for service, over 5 years i could buy a new bike for the money spent in the shop, so what do you guys do? self maintain? what manual do you use? (latest i can find is 'Suzuki GS500 Twins 1989-2002 Workshop Manual') Cheers, Old Man.
