Basic YFZ motor mods

[JDiablo]

What are some basic mods you guys are doing internally?
I would be guessing piston
Cams
valves
Springs
Clutch basket
Clutch plates

Anything else?Anyone have any super huge stroker in there engine?

u need to try get the thing running b4 u start modding the engine :p

my engine is stock, but some good stuff is:
--wicked 13.5:1 piston
--web cams
--wr crank

i think most except for a few wild dune bikes are keeping the stock valves........not to mention they're almost $200 apiece for TI ones

i think you can put yzf clutch parts in it so you can have an extra disk.........but idk. i think muff did this, but again, idk for sure. just go on yfztech and look around. a bunch of those guy's bikes are rockin out big time :scary:

Don't modify the engine until you are redlining it and pushing it as hard as it can possibly go. Most people do the WR kit, clutch plates and basket, intake cam, and then other small things.
