is a little chatter or chugging when clutch is engaged

Sounds good to me; definitely NOT too fast. Was this with engine hot or cold ??

I'm still curious about the recordings though; they all seem to make the "thump" a lot more pronounced than when your are standing right there. Guess that will remain a mystery!

David, why do you think it is too fast?
This isn't a loping Harley we are dealing with here......... :biggrin:

If that recording was while his bike was idling, that sounded very fast to me. I have my idle screw set much lower... I turned mine down until the engine was just about ready to stall and then turned it back up about one full turn. That is how my bike idles...

Easy, I thought you were into saving gas !!!

I'm into saving engines. Did you miss the part where a really low idle speed can cause engine damage ??

I don't think his is really going as fast as you think it is.

David, in case you haven't read the handbook, suzuki say 1200 to 1400 rev/min for tickover. I'm not saying that you MUST adhere to this, but just that you might like to use that as a reference point. A car is set at, what, 800 (?) rev/min, so the gz should sound as though it's ticking over at 1½ times the car.

im all about saving gas but when your driving the engine is revved up way more than that, you should spend way more time moving that stopped. some one said earlier the bike will run better with the idol set higher, well it does i noticed much better pickup right after i shift gears. i tried to turn the idle about a turn lower and the bike did not have as much pickup, every time i stopped i turned it just a slight bit higher as soon as i felt that extra pickup again i i left it right there. i think i got it set just right.

so my advice is to warm the bike up all the way than play around with it until you get a noticeable difference in pickup as soon as you do stop right there and than you probably have it set just right..

i would rather burn a little more gas while stopped than damage the engine. and i would rather have the bike take off a little faster from a stop and between gear changes. it is only one cylinder it makes perfect sense to have the idle set a little higher.

damn i need to learn how to spell idle i keep reading over my post and catching my self spelling it idol

I think you've been watching too much American Idol :biggrin: ... This is why I am glad I joined this forum. I honestly did not realize that the idle needed to be set higher on our thumpers (should re-read my manual). I guess I will have to turn my screw another half turn or so... I do run Castrol FULL SYNTHETIC 10W-40 oil though. I would guess that that would be more benefical to the engine at low idling speeds???

Easy - your thoughts?

it was hot, took it around the block witch is about 10 miles

i believe most cameras have a condenser mike in them, that is why it is possible for them to pick up sound from across the room quite well . condenser mikes are extremely, extremely sensitive and pick up every thing, there is probably also a little compressor in there witch will amplify and bring out the suttle sounds out more so you can hear every thing that way you don't get lousy dry audio reproduction. if you don't have some kind of effect for instance compression, slap back delay or a little reverb audio will sound dry and lousy.

that is my educated guess on why they would sound different when recorded

well im sure the full synthetic would help, but better safe than sorry. that's what i always say. i just put some mobile1 racing 4T 10W-40 in mine, full synthetic, they sell it at walmart. its shifts much smoother now and i only get a clunk going in to first gear some of the time. most of the time i get a nice little click instead of a clunk. before i changed the oil it would always clunk loud, after driving 20 or 30 miles it started to clunk less and less after about 100 some miles i only get a occasional clunk.

well this post turned in to something that will probably to help some folks not ruin their motors, my first thought was the have the idle set kind of low

Synthetic is a TINY bit better at a lot of things....so tiny that for most things it doesn't matter.
I suspect that includes things like abuse from running an engine "out of spec.", either too fast or too slow.

What it is REALLY good at is not breaking down due to heat. I consider that important in an air cooled engine .....that tends to run a bit hotter that a water cooled one and can over-heat without you even knowing it.

I use synthetic in everything I own mostly because I tend to keep things with an engine for a VERY long time........and those tiny little advantages tend to add up over, oh say 150,000 miles (for a car, not a bike).

City folks won't understand that. :roll: :biggrin:
