does anybody know where those valves go and if there hard to install.

 

Get a service manual.

 

They are easy to install. They go between the carb and the cylinder head. A Rad valve is a great upgrade for the Blaster.

 

I have heard that the rad valve doesnt make alot of improvement but I personaly have installed the boyesen torque reeds and they made a very noticeable differance. They are very easy to install. Just take off the carb clamp on the engine side and ramove 4 small bolts fom the intake manifold. After you pull out the reed cage just remove 4 small screws ,remove the old reeds and put in the new ones.

 

ram valves and rad valves don't do much. delta v-force reed cages do. you can adjust them for bottom or top end power.
