I bought a complete CRD exhaust system for my raptor (very cheap). It is a new french material for quads. CRD is known for itīs quality on YZ426īs pipes on the european championship.

Have you guys already tried this pipe on a raptor, and what jetting should i use ?

I live in Portugal, i am at sea level and my mods are :
- K&N filter
- K&N jets 148/150 main, stock pilots, K&N springs and needles
- 3 and 2 turns on air mixture screws
- Complete exhaust system, pipe and silencer from CRD.
- No Snorkel
- 14 thoot front sprocket

I am thinking in going to 150/155 main what do you think ? What should i change ?

thanks

 

With the lid on I think you will be too rich.
