Thanks for reaching out!
These Keihin CR carbs come ready to mount on and go, equipped with mounting spigots, velocity stacks, and velocity stack covers. Most replacement and tuning parts are available through various suppliers.
All CR Carbs Are Pre-Jetted With The Assumption of a Stock Motor and Aftermarket Exhaust.
If your bike has high-compression pistons, aftermarket CAMs, or other performance motor work, please specify in the proper fields when ordering.
The CRs are pre-jetted to a baseline that's intended to be as close as possible, but fine-tuning may be necessary for the individual bike. As such, WE WILL NOT ACCEPT RETURNS DUE TO "JETTING".
Thank you for your inquiry,
