Good Day fellow GS'ers. I've decided to freshen up my ol GS1000. Needs a valve job and the pistons and rings are just past their service limit with standard 70mm pistons. I've had trouble finding a good set of .50 or 1.00 over pistons and rings so I've decided to go with the 1085 Wiseco kit. It's a shame to shave so much off the cylinder walls but it's gonna be done. After having 2 very reputable GS gurus view the top end, we've decided the bike needs new exhaust valve guides and intake valves also (Picked up some nos oem ones on ebay) and a good valve lapping, of course. Parts have all arrived so it's off to the machine shop for some work next week, hopefully.
My question is this....I have vm26 carbs that have been rebuilt and work great. Will I be able to continue using these carbs with the larger bore kit? If so, will I need new jetting? Just trying to anticipate what's next after the engine top end is freshened up. Everything is bone stock including the original exhaust system. I will be using the bike for street duty only so tuning up to race really doesn't interest me. I'll just buy a Hayabusa if I really wanna move!
