Boost bottles are only useful on piston port 2 strokes. They are of no use on our reed valve motors.

Thanks spaz12. I don't seem to have issues with it. But I'll try it without the boost bottle and see how she runs.
I've tried a few different setups for my transmission and have had mild success. Only on my last ride my fuel line blew off and wouldn't stay on so I did the walk of shame home with my wife helping me push it up a long hill.
I had the red 2000 rpm contra spring on when it blew and had the yellow one on yesterday without any issues. Running Black MHR clutch springs 8000-10000rpm. Stock clutch and variator with 3.5g Athena weights. The red spring is to hard for me and keeps me over reved. I am going to put the yellow one back in. Other than that I Have the street race pro replica exhaust and stage6 intake and 21mm PHGB carb. I ran a new throttle cable and manual choke cable.
I appreciate any input to help me get it tuned right.

I was a little confused with what you said that you were running so I looked back on your old posts and see that you were running the street race cylinder and the pro rep pipe... Correct?
I've never run that pipe, but I've heard that it can be a real pita to tune, but when tuned correctly it's a nice pipe.
So I would do like you said and put the yellow contra spring in it and then start playing around with your weights. Carburetor and cvt tuning are right up there with my least favorite things to do, but you know how it goes; lots and lots of fiddling until you get it dialed in, but rewarding when it's finished. Assuming you haven't pulled all your hair out :)

Use the yellow Contra and play with the weights. I'm not sure where you'll need to be with the yellow Contra, probably somewhere around 5gr.

With a stiffer Contra you need heavier weights to keep it around where you were with the softer Contra.

scooters and mods: 2002 zuma top trophy bbk,1500 rpm clutch and contra springs,stock carb with stock airbox and snorkel removed.4gr rollers
Post Re: My 2005 BWS
I had a stage 6 pro replica and it needs to stay up there in the rpms.i had 4grams dr pulley sliders with 1500 contra and clutch but your 2000 clutch is probably a good choice for that pipe.some guys go 3.7 on the roller,sliders.i weigh 190 so if your light it will help you take off better.

Post Re: My 2005 BWS
Got everything tuned and running.
Original issue was remedied by drilling some holes in my airbox as the opening with the snorkel removed was still to small and was choking out the engine. This gave me way better performance but was much louder in return.
My setup:
70cc Stage6 aluminum cylinder
Kevlar belt
21mm dellorto carb
#92 main jet
Stage6 Manual choke cable
Single Throtle cable
6000-8000rpm clutch springs
Stage6 pro replica street race pipe
Yellow 1200rpm contra spring
3.5 gram dr pulley weights
Stage6 intake
Fiberglass reads
Mini multi stage6 digital rev counter
Yamaha large windshield
Custom rear turn LEDs

It has good pull of the line and pulls hard right up to 60kmh and beyond.
Thank you all for your help. I'm very happy with this setup.
Just in time to enjoy the season.
Knees in the breeze not a care in the world.
