thanks alot to trygstaad 872 R

squid2020 · Dec 15, 2013

Got back from southern CO this wk and was first ride on new 872 from tryg. Just like he said pull the rope and go, great power and clutching was very responsive and felt like it wasin power all the time. Now just gotta find a way to feed the beast, took alot of pow to the hood and kept plugging intake. Thanks alot to Dave and all his work...

From low to high elevation like southern CO they run flawless congrats !

squid2020 · Dec 15, 2013

ya was great snow while we were there and was little leary of breaking in a fresh top end. We stayed in high 11s- to mid 12s, and it ran great when i could keep the pow off the air box. A lil shop time to fix that and figure out how to get better float out of it. great instant power, but sucks when it just wants to trench..

Do you have the carb or etec version?

squid2020 · Dec 16, 2013

Carb R motor, 20% premix with 110 race gas...

adam8781 · Dec 16, 2013

I would dump the injection system for 32:1 premix if it was my motor. Smoother running, less weight, longer motor life etc

for the intake, drill out the back side of the xp airbox and vent it, You can do this with simple prefilter material, powerair intake vents, they use vacuum to open, so unless the stock intake is plugged they stay closed.

Or a jc vents intake kit
http://www.jcscustomvents.com/catalog/i125.html

Lots of people doing the holes in the back of the airbox also report a gain in hp. And since you are running a big bore the stock airbox falls short of the air supply that motor wants.

squid2020 · Dec 16, 2013

Im gonna leave injection on and try to keep mixing 100;1 with it. tryg said it wont hurt and always know its getting oil.

I just ordered the extreme air vents cold air intake 70$ and ez install, didnt want to mod any other air box part and looked the simplest of what i looked at.

Next is a new track!!! Challenger 2.5< tryin to keep it up on snow and plant some ponies. Love the power and clutching from tryg, feels like its always in power. pull the rope and go just like Dave said, so far so good.

Daves engines are top notch his customer service is one of the kind .We've just received are 4th motor from Dave and doing 1 more fore sure .I haven't help do any of his E 872, but with 2 2013 xm's 163 in the group I can not see them letting a old 08 154 (sleeper)beat up on them again this year Lol.:face-icon-small-bluCheers

Has anyone tried Tom's 3d arms with this power plant.

adam8781 · Dec 18, 2013

there was a topic on dootalk about the 3d arms a while back, they were hugely liked. I would talk to http://www.shoptomssnowmobile.com/ about the setup for the 872/880 setups.

tukernater · Dec 18, 2013

Thanks adam8781 I just spent about half hour on the phone with Tom What a great guy to chat with answered every question Clearly.Thanks Tom

Summit8 · Dec 22, 2013

The Powair Vents on the airbox work good, had them on a couple seasons now, never really notice the intake getting plugged up, they must be working. Or maybe I never get any snow on it.:face-icon-small-hap

squid2020 · Dec 24, 2013
