I just put mine on this morning. Won't have a chance to use it until this weekend. I'll be back on the 4th and can let you know then. Somebody said they had a problem with no heat shield and being close to your leg. Mine looked like it would be alright, but I can let you know when I get back how it was.
I bought two of them but returned them because they don't have the heat shield provision.
The Sparks does,, as does the Yoshi.
To close for comfort with no heat shield provision. Your leg is inches away.
Stock YFZ450 pipe with heatshield.^^^^^
The Yoshi Pipe protector.^^^^^
Looks cool too^^^
Nasty burns from the pipe otherwise, or you may set your pants on fire. Read other posts here in YFZcentral of those who have. Any company not offering simple protection like this I don't want to do biz with.
