has any one out there put the yz exhaust cam in there yfz 450? if so any feed back ..thanks

 

The only difference is the timing mark on the exhaust cam I think.

 

Selector has. Give him a PM.

 

Are you sure about that??? what are the lift and duration of the exhaust cams (yz and yfz)??

 

The lift and duration on the YZ cam are not any different they are identical. The only difference is the decompression mechanism.

 

that sounds like a good idea!! If the YZ cam has a better lift and duration than I will pick one up, they are only around 100 bucks. Mine still starts fine now with the decompression mechanism off one tooth. Alot better and easier than my big bore Z400 with no decompression mechanism did!!!

 

thanks ridley...any info will help ..it's like shewendi said 100 bucks for that mod is not bad...

 

I dont think there are any differences. WR guys have been doing this for years and Yamaha has stated that the YFZ uses a YZ intake cam and a WR exhaust cam. until I hear exact specs of both cams im not spending any money on an a YZ exhaust cam.You can get the exhaust cam from bob @ magnolia tractor for $108. www.magnoliatractorinc.com

 

yeah i talked to bob the other day..he has goood prices on his stuff...i got some AC racing pro peg nerfs from him for 229$ retail is 289...he is running the yz cam in his yfz 450...he told me that he got some very good HP gains out of it..

 

Do the cam mod and you will get the same gains as changing the cam. I know some people have had starting problems afterward but mine runs great. Call a yamaha dealer and get the specs and you will see that the lift and duration are identical.
