J-Madd Posted December 14, 2016 Report Share Posted December 14, 2016 192-196 is not nearly a wide enough range. 180-190 would probly be better. manually operating it would never work well on a atv. manual sliding pipes like boats use wouldnt work well either. theres no way you could pull a bunch of levers back and forth, at the right time, while operating the throttle and clutch, while trying yo turn and jumpI meant all or nothing. Set it for 192 (or whatever Serval exhaust timing is) while you're in the trails then set it to 196 (Cub timing) when you wanna run fast straights. I didn't mean adjust on the fly.

hercalmighty Posted December 14, 2016 Report Share Posted December 14, 2016 Trinity valves work very similar to the Rotax Rave valves. However, they use a keihin jet to bleed off pressure, kinda like a waste gate on a turbo set up. Smaller jet bleeds less, so you get a faster operation of the valve. Larger jet bleeds off pressure and makes the valve react slower. It's not a bad set up. I fiddled with a 421 cheetah and it was actually pretty easy to get the valves dialed in for a buddy. I've got a 535 on the way now, so I'll see how it goes a second time around.Tricked. I was told that it was the opposite way with the jets. Smaller jets make the powervalve open slower and bigger jets make it open faster. Correct me if I'm wrong.Now, I know you and others have experience with the rotax valves. How are they adjusted? Is it just spring tension? Sent from my VS990 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Rotax are spring tension, I said similar in that it is a blade driven by pressure. Quote Link to comment Share on other sites More sharing options...

J-Madd Posted December 15, 2016 Report Share Posted December 15, 2016 like a toggle switch or something? seems like madmax has one to turn on the supercharger lolI didn't say it was realistic! At best some kind of threaded screw through the PV and into the cylinder that can be turned in and out. Quote Link to comment Share on other sites More sharing options...
n2otoofast4u Posted December 15, 2016 Report Share Posted December 15, 2016 like a toggle switch or something? seems like madmax has one to turn on the supercharger lolIn the early/mid 00s the yamaha sleds used an electronic servo to operate the pv.... this isn't as hard as your thinking. I mean fuck, if you are wasting the breath to put actual thought into PVs on a bangshee you might as well waste the energy to do something to control them.

hercalmighty Posted December 15, 2016 Report Share Posted December 15, 2016 The Two Stroke Shop had a killer setup for an electronic controlled setup for the cheetah. I think it might have used an zeetronic setup. If someone wanted to do the fab work could probably fab something up using the the rz350 electronic setup too. I was looking at the cart guys pv setups and it looks like they use some sort of air pressure setup to be able to adjust the way the valves open. My biggest problem with the trinity valves is that the mating surface for the top of the powervalves is so small that it leaks air. If someone could make the valve body with a bigger surface and machine an o-ring groove in it, I think it would be better.

locogato11283 Posted December 17, 2016 Report Share Posted December 17, 2016 All of you pipe dreamers need to call CP and find out what is ACTUALLY available now that it is under new ownership. You will be sadly disappointed! Yep. They're only making certain things at certain times. You did know that Elaine bought it back right?

guns4children Posted December 17, 2016 Author Report Share Posted December 17, 2016 Someone buy this!! Replace the power valves and BAM!! bad ass trail motor!. Things probably ported beyond repair though.

sleeper06 Posted December 17, 2016 Report Share Posted December 17, 2016 They've been using lever controlled pv set ups on skis for a while , you might wanna check that Ave out . I've seen them on gp1300r set up for the snakes Quote Link to comment Share on other sites More sharing options...
