KaN Powersports Posted November 2, 2013 Report Share Posted November 2, 2013 ^^^^They do work like the ones on a sled! Oh wait, it IS a Skidoo Valve. I'm a fan of Servals as well, but don't discredit a variable exhaust-good way to get the best of both worlds-so to speak..... Quote Link to comment Share on other sites More sharing options...
n2otoofast4u Posted November 2, 2013 Report Share Posted November 2, 2013 Your saying the PV supplied by trinity is a rotax PV? Quote Link to comment Share on other sites More sharing options...
KaN Powersports Posted November 2, 2013 Report Share Posted November 2, 2013 It's his valve, but the exact same function. Different calbrations. Plenty of cylinders out there with the pain old Ski Doo valves-resprung in them:)... Quote Link to comment Share on other sites More sharing options...
Coupelx Posted November 2, 2013 Report Share Posted November 2, 2013 Far from it. I do know what oem valve will fit though. Im gonna pull a Passion and decline to comment further though. Quote Link to comment Share on other sites More sharing options...

KaN Powersports Posted November 2, 2013 Report Share Posted November 2, 2013 I haven't got the 'pic' thing down yet. Here's a link to some https://db.tt/N7q1CQ9U There is an array of guillotines out there that fits this body.... Quote Link to comment Share on other sites More sharing options...
LowlyOilBurner Posted November 2, 2013 Report Share Posted November 2, 2013 I haven't got the 'pic' thing down yet. Here's a link to some https://db.tt/N7q1CQ9U There is an array of guillotines out there that fits this body.... It looks pretty similar, but I really wonder. To the OP, I have a 485pv motor setup by Wildcard Racing and it's a great "all around" motor. Boatloads of low to mid range, and topend that still can make your asshole pucker up. Not a fan of the $300.00+ pistons it requires. Quote Link to comment Share on other sites More sharing options...
camatv Posted November 2, 2013 Report Share Posted November 2, 2013 they are modded ( maybe..) h-2 pistons.. they are a larger bore and when using a wiseco "premium quality" they are going to run a little more. hell most 68mm smaller wiseco's are in the 195-220 range depending on where you get them 140 ish is what the 71-73mm run in cheeta. plus they last a shit ton longer than the piston eating cub setups. ( at least what I HAVE seen) the valve's in the larger bores ARE larger spread. the ones in my 73mm are set up for 73mm width. the 68mm bore has a 68mm bore width type valve.. just trying to clear up some stuff here. these cylinders already have a bad rap and lots of "misinformatino floating around. the rotax valve body is really close to fitting. i would prefer them for the spring adjusting.. actually perfect would be cable driven using TPS and load off of motor.. instead of exhuast pressure BUT they still work really good. the 400 bore PV cheeta can use a stock stroke crank and in my OPINION make all the power you would ever need in a trail bike ( so crank cost is lower also) hell i ahve done a few with stock rebuilt OEM cranks.... if the $$$ isnt as much of a problem you can and would probably be very happy with a 400 pv cheetah. 1 Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted November 2, 2013 Report Share Posted November 2, 2013 So, you use a keihin main jet to adjust how and when the power valves open? Sounds like a shitty setup to me. I assumed they worked like the exhaust valves found on the Polaris and Ski-doo sleds. I think I will stick to the cub and give it high comp for better bottom end.Using a jet is quite nice. It allows for more fine tuning and much less effort to change then the process of swapping springs and then cutting them back to fine tune them.

Big Mike NY Posted November 2, 2013 Report Share Posted November 2, 2013 Serval... Where can I find out more information on the serval setup? I have read so many good things about serval but cannot find any specific information on it... Thanks Mike Quote Link to comment Share on other sites More sharing options...
sprinklerman Posted November 2, 2013 Report Share Posted November 2, 2013 Where can I find out more information on the serval setup? I have read so many good things about serval but cannot find any specific information on it... Thanks Mike Type "Serval" into the search box. Or "serval" and "bansheehq" into google. youll find out all the info you want on them. .. and believe me,theres a lot of info out there on them. Should be all you need to know.

Good to know about the valves for the bigger cylinders. I was informed wrong. For those wanting to run 110 rods with a 68mm bore wossner makes an excellent piston thats cheaper than the cp/trinity/whatever stuff.
