Is there parts from a '07 and newer 450, that a guy could bolt on or modify an installation slightly, on a '04, to make the oiling better than stock?

How is the jet installed/secured? why did you go with a jet and not just a hole?

I'd be afraid of the jet coming lose and causing all hell.

hey guys.

I have the oil update kit on sale on ebay for $170.00

You get the new hi flow oil pump and the yamaha nozzle that works better than the jet or hole. This is Yamaha's fix for the problem and my kit will make your case and oiling system the exact same as the new 450's. this kit is for ALL 04-06's

You can also just call to order

I ran across this thread a while back when i was rebuilding my engine . so i gave it a shot took about 30 min of precise measuring and it was done, turned out great. thanks for the right up!!!!

but i know there were questions about the athena bb kit being in the way. i have pics that i would like to get posted of it. but the athena actually has more room than the stock because there is a bigger moon shape at the bottom of the cylinder.

if you have a hard time finding the angle of the jet to spray(3 axis tilt) just hold the drill bit on the spot were it will be drilled, then move the crank up and down real slow, find the angle at which the bit is pointing at the piston pin the most.

I sent my case to j&t products, bout 200$. Im fairly new to riding and wad my first time digging into the engine. When i put the case back on, am I supposed to use thread locker or??? Tightened down the bolts but felt like they would strip out really easy.
