I was speculating one cold morning how much i can safely spin my gs motor without risking any excesive wear. High revs are bad for sure but where is that limit. And should it increase gradualy and how fast ?
So how much do you rev your engine went just started in the morning? Anyone read any scientific tests maybe?
Also everytime i rev the gs high (8k-10k when it is warm) am i shortening its life? Or the engine doesn't mind that at all.
Also are too low revs also harmul (2k-4k)?
Personaly i am keeping under 4k when cold, and reving past 6k occasionaly when it is warm, i usualy keep it under 5 in trafic riding. Is it ok or not, why and what are the consecuences (prob wrong spelled:()
Thx for any experience sharing
under 5 when cold, out of the red when warm. just check your oil level often, and keep good oil in there and she'll run forever.

Under 5, but not so low it lugs (>3).
Once it's warm, you can take it up to the redline, but you probably start losing efficiency at 9-9.5K (someone please correct me here if I'm wrong). You generally want to always keep it in the zone where you can accellerate quickly (which is just as important as being able to stop quickly, IMHO)...that is, near the lower end of the powerband. If you twist the throttle and it feels sluggish, you're running in the wrong gear. By keeping the RPM's low, you're making the engine work a lot harder than it needs to, making it spin up the wheels in areas where it has sub-optimal torque. Not a big deal (you're not in danger of your bike exploding), but not ideal either.
One more thing to keep in mind: cold tires don't have as much traction as warm tires. Give them a few miles to warm up before trying to milk all the traction out of them (don't corner hard, accellerate hard, brake hard, etc.).
'Course...this is my opinion, and it could be all wrong. ;)
I guess I've been workin my bike pretty hard for the past few months then, I'm usually between 3k-5k heh. I guess all those extra numbers on the tach gauge do make it different than a cars :lol:
I rarely let it get below 4k, and am typically shifting around 5.5 to 6k

Mine's been dyno'd at its peak at 8400-8500rpms... which mean most efficiency is lost after it... you can still shift around 9000rpms to keep in the max power range in the next gear though and it would be an efficient shift.
I keep it under 5000-6000 if its not fully warm (I let it be able to idle alone before I leave). Then afterwards I keep it under 9K.... however the more you rev the more wear you put on the engine... that being said these motors are still pretty much bulletproof... keep your jetting right, your valves adjusted and your oil changed frequently you should be just fine.
A big tuning and fluid replacement frenzy for my bike is going to happen within the next month. I know its not tuned properly, knew it when I bought it, and hopefully I'll be able to get it running better. BTW put yourself on the GS rider map gs500fromnb, we need more Canadians on there :mrgreen:

done 8)
I don't know if anyone needs any more Canadians anywhere.
Just kidding. Because if I was serious I'd of called it "America, Jr."
