i put in all the parts they gave me in the kit and it runs perfect and is amazingly better.
Good thinking. You do get a little more power, but the larger benefit is cooler running, quicker starting and smooth top to bottom throttle response.
Easier to ride, not more challenging.
It happens quite a bit where folks will seek help, we or the manufacturer will tell them all that's required then the new owner resists doing all of the job for some reason. Then they don't get all the benefits.
Glad you like it, it's quite a difference.
Now you should install a 14 tooth countershaft sprocket.
You'll have a first gear actually good for something (it sure isn't stock), you'll lose no climbing ability and it will pick up appx 10 mph top end speed.
Many will say they don't need that. Most will find eventually they do.
