Beefing up my 96 vmax 600 xt

[Chris Stanton]

Hello everyone I recently purchased a set of 96 vmax 600s and are stock as far as I can tell. Looking on here for some mods....found a couple so far including adding a thinner head gasket....I think thats where I want to begin, although I have been looking on here with no success....guys talk about it but not really sure where to find one...any help? Also any other suggestions would be greatly appreciated thanks in advance.

I thought the 96's already had the thinner head gasket....

The 96 had the thicker head gasket. I got a cometic gasket set and it had the thinner gasket. Here is the link to the kit I bought. https://www.denniskirk.com/cometic/hi-performance-full-top-engine-gasket-set.p261400.prd/261400.sku You can also get the oem gasket from a 94 or 95.

Any Motorsports dealer can order the gasket. I ordered an OEM.

I used that set set w/brand spanking new primary & secondary springs. I used an 8bvfa yamaha helix and a brand new Carlisle belt. Page 79

Thanks will be ordering 2 asap.....what else needs to be done along with the thinner gasket? Ex. jets, needles, reeds, ect.?

 

[A couple of bucks]

You'll need to move the needles 1/2 a clip. If they're in the 2.5 position, you'll need to put them at 2.0.

Thanks what about the jets and reeds? And if there's anything I'm forgetting to mention?

Jets stay stock. I put fresh reeds in this summer. Definately made it start better and run smoother. Had to order directly from Carbon Tech. http://www.carbontech.com/snow/yamaha.html

Danny, so you recommend leaning things up then?

I am on the nervous side of things and actually installed a larger main jet, and raised the needles 1/2 a notch to richen.

Just curious, but what do you see for top speed now vs stock?

 

[Chris Stanton]

So if the clips were at 2½ id move them to 3? And go with a bigger jet?

 

[PMaine]

The lower the clip, the richer the setting.

The lower the clip, the richer the setting.

I think of the needle as a wine bottle cork. The further the needle is allowed to fall, the leaner it will be. So by moving to clips lower, it doesn't allow the needle(cork) to drop further into to hole(wine bottle).

Ok you guys didn't really answer my ? Lol

Ok got the gasket kit and the way the weather looks, done riding for the season. So looking for step by step instructions on how to do the installation and other things to check/change/replace? I can add that it seemed to be a bit of a gas hog.
