Well I replied to your other post but anyway what spring are you talking about clipping and where did you read about this.
I dont know, I was just reading about it on HL and one guy says it only works on the rincons but it might be worth picking up another spring and giving it a try.
You already did this? What bottle are you talking about
Oh, I guess the 450 doesnt have this bottle. So is it worth clipping.
Well I couldnt stand it anymore so I decided to be the ginny and went and cut my spring but it did it 1/4 inch longer than half and yes it does make a difference in throttle response. Very good and easy little mod.
All this does Carl is let the needle move up faster. By cutting the spring its taking the tension off the needle.
I did it on my 04 last night and it does make a difference. As for your throttle return it is just fine, just like normal. I dont know about the 13 coils but the spring is 4 1/2 inches long and I cut 2 inches off. Hope this helps ya.

Ya thats right, I just went out and counted the 2 inches I cut off and its 13 coils. If ya have a tape just measure 2 inches and if not count your 13 including the 4 that are stacked together at the top and then 9 down.
Good luck, I think you'll like it.
Come on now Carl, I already did it. Plus if it doesnt do anything for you or you can't tell a difference then it aint gonna hurt anything leaving it cut.
Good, be sure to report back when your done.
Its on the 500, you dont have a 500.
Clipping your spings lets the slide and needle move up faster letting more fuel in.
