FireHead Posted October 16, 2007 Report Posted October 16, 2007 Are any of you guys cutting your one piece cylinder base gasket to accomodate the coolin pockets in the top of the case? I know it might seem like a silly question, but I am inclined to do it. The downside is that it makes the surface area on the gasket awfully thin in a few areas. The upside is that any temperature reduction or normalization near the crank chamber will always make you more power. What do y'all think? :geek: Quote
Snopczynski Posted October 16, 2007 Report Posted October 16, 2007 so the cooling pockets in the front of the case on the top? Dont they only go down about 1" or so? Quote

Yeah, that's what I am talking about. I don't think there is a way to use the rear cavities without machining the base of the cylinders. I think I have decided against doing this as I think the gasket may be more prone to blowing out if I cut it for the previously mentioned purpose. However, I am pretty sure I have done this before on a few other engines where I actually did machine the base of the cylinders and my old triple design made the upper portion of the case wet via a similar manner. :geek: Quote
bigboybanshee Posted October 16, 2007 Report Posted October 16, 2007 I personally don't do it, I just trim the base gasket to match the porting on the top case half...but never messed with the gasket to accomodate the cooling pockets, only the transfers. :geek: Quote
Bansh-eman Posted October 16, 2007 Report Posted October 16, 2007 no balls! just do it mark, its not like you have anything better to do other then fixing more broken motors lol Quote
dajogejr Posted October 16, 2007 Report Posted October 16, 2007 Since the rears are plugged off on cubs, the only thing I do is cut the base gasket on the bottom of the cub cylinder to match the transfers...and it's very thin in the middle and on the sides...kinda like my hair line.... That's why I use a thin coat of RTV as well, for insurance... Quote

dajogejr Posted October 16, 2007 Report Posted October 16, 2007 rtv on your hairline cant be healthy Yeah...but there's a spot right above my ass I use show towels and RTV as a "wax"...works wonders. Hi temp RTV, of course.... :yelrotflmao: :yelrotflmao: Quote
BigRed350x Posted October 16, 2007 Report Posted October 16, 2007 I cut mine for the pockets once and it blew out on my first ride. Haven't done it since then. I just trim them to match the case porting and call it good. I'm sure if you use a thicker gasket material it would hold up, but that will mess with your port timing and squish and blah blah blah... - Jared Quote
Bansh-eman Posted October 16, 2007 Report Posted October 16, 2007 holy balls jared your still alive? i havent seen you around in a shitgrip Quote

I have decided not to accomodate the lower cooling pockets with the gasket trimming............and leave well enough alone. :geek: Quote
FireHead Posted October 17, 2007 Author Report Posted October 17, 2007 holy balls jared your still alive? i havent seen you around in a shitgrip How the fuck long is a shitgrip? I don't think I have heard that one before............................and do we need to talk about your involvement with holely balls.............you weren't around the lawnmower when it fought back. :biggrin: Quote
