Case drilled oil cooling

[3504life]

I know there is a thread for the case taped oil cooling but I couldn't find instructions. And is there a big difference between the big bear and case cooling? I kinda have all the parts for the big bear kit, but I broke the cap that the hoses go into. And I would like to do the shift mod but not a lot of cutting/welding. So what's the best method?. Thanks

Sounds like the clutch cover mod will be your best bet. I like the bigbear setup for its simplicity and being a bolt on part. But they say the clutch cover mod cools the head better ( i think)

Lol I'm mechanicly inclined so wrenching dosnt bother me

 

[87warrior917]

Ha i mainly went with the bigbear setup cause i was too afraid of messing the clutch cover up lol

 

[3504life]

Ah! Man you sounded confedent with the case mod like you have done it

 

[87warrior917]

if your're nervuos about messing it up, clutch covers are cheap on ebay. page 8 of this thread has pics and instuctions for the clutch cover mod http://www.yfm350.com/forums/showthread.php?t=15037&page=8

Its actually pretty simple to do, if you follow the instructions in the thread its almost impossible to mess up. But like elwood siad, just pick up a spare from ebay so you have very little down time.

yeah just don't forget what size to tap the hole. If you sspend 5hrs polishing a cover and then drill it to big and mess it up you will be mad trust me.

the cover was cheap no big deal but all that time polishing it just to throw it away still pisses me off

 

[elwood]

I have another cover in the garage think I paid about 12 shipped for it, just haven't gotten around to tapping it (still debating on polishing it) cooler and hoses are hanging on the wall by it.

 

[1998yamahawarrior]

I keep debating on polishing the one I have tapped, but then I think to look good I should polish the valve covers and cam cover.

 

[elwood]

and don't forget the oil flter cover

 

[1998yamahawarrior]

Damn it that would be even more work!!! LOL Still debating on doing it or not.
