What's a good motor mod...

[Skadi]

I need a bigger sled.... I'm trying to keep up in the chutes with a 50 lb lighter chick on an M1000...

I ride an 05 800 HO, stock. Well, not totally stock. I have a 159 Holtz skid under her and a fresh for this least season RK Tek OEM replacement top end...

I've ridden Hymark860's 860 and fell in love.... Didn't know a ski-doo could work that well!! Gimme some of that!!

His was done by Turbo Al and also has pod air filters with adjustable jetting? and the drop and roll with a 156 I think...

My issue is: I want a reliable mod! I don't want to stretch the limits of my sled so far that I wear out components and then start to get into the unreliable mod sled situation! Also, I need something that I understand... If I have to have all sorts of extra junk on it to get it to run right I need to know through and through how that stuff works and exactly what it's doing so that I can work on it! I would like to do as much of the work myself as I can so that I learn about the parts and pieces... but I don't have a FULLY set up shop yet.

So, who makes the best big bore kit? what do I have to do to make it reliable -meaning all the parts and pieces, gotta know how much moeny I need to save up! And then once I figureout what I'm getting I need to dial in my clutching for that. And my intake... I've heard those pods SUCK! Seems to me like they wouldn't get cool air.... What's the story with those things?

Feel free to chime in here and give me info, I know it's all just opinions but the more I hear the more it gets my brain workin down the right path!

Thanks!

Big John can set you up with a reliable 840 kit that will run with the M1000

Twin pipes and N2o might be a good add on also!

I had an 840 with an Aaen single, stock air box...stock everything pretty much and it ripped. This season I put on the Crank Shop twin pipes and have been trying to get them dialed in all season. The pipes work great at low elevations but they need a little "tuning" for higher up.
If I were you I would just get the 840 top end kit and call it good for the season.
You don't need anything else to make it work, intake, pipe leave it all stock.
Then next season if you want more you can get the 800R airboxes (good for 2-3hp) and either go with an Aaen (5hp) or the CS pipes (talk to me by the end of next season before you do that though).
Lightening up the sled won't hurt either.

10-4 on the airbox thing. i was already looking for one... however. with josh's sled he needs to 'tune' it on the hill a bit every now and then. I've seen his sled run up to the top of a climb, sound a little blubbery... he comes down, tweak, and it RIPS to the top of the same climb! You can only have this adjustment if you run the pods right? So i've been holding off on actually buying that 07 airbox until i make up my mind!!

and twins... makes me nervous, i don't know why, i just feel like i've seen a lot of doos that have issues once that go with twins??

You know what my feelings are Skadi.


Dont buy something to be different. Otherwise you'll be on your own when needing help. Ive only seen one 840 and it grenaded and know one person with a 880 from bmp.

Decide what you want . The 860 can be run with dpm and a airbox. I just choose not too and run power jets with pods.

X2 on what Josh said....You will have his knowledge locally, and Al is a 5 hr drive from Spokane. The other builders are further away. I have ran Al's stuff, and it works well...

Best Advise: Call Big John.

On my 06 800 I hab BJ doo a porting job, reed spacers and a HPS can. For an 05 you will also need the chrome rings and a little head work. It should get you up around 150hp, great torque and better throttle response. Best part of all is same as stock reliability without needing to be tweeked on the hill. Then a good clutch kit and you will have a runner.

Do you mean 160ish HP? 150 is the stock HP.

 

[quickdraw]

05 800Ho & 06 800Ptec were 140hp. 07 & 08 800R motors are 150-154hp depending on who's dyno you believe.

If a guy runs a 800R airbox on a 800 H.O. engine, what kind of clutching do you have to do to it? Or can you get away with the clickers alone on the primary ??

 

[Rob1334]

I would recommend new pistons! should take care of the low power problem

First off...SHR offers more support than anyone out there..I EVEN help with bmp stuff (and MANY others)..so the comment about "on your own" does not apply to me...as for "seeing motors gernade"....wanna see my list of "other builders" carnage that I rebuilt???

Trail mods are just that...we all doo our best to make more hp...but you would be surprised how many guys get my kit then call me back and ask were the main jets are??? now if that motor has a problem is it my motor or the owner???

I can offer a motor that works well if cleaned/assembled correctly to spec (using goofy tools like torque wrenches)...clutches are clean and tuned to the new motor (basic clutch knowlwdge TRA tools would help here too)...and of course the carbs need to be cleaned and jetted, maybe even re-jetted to dial in your combo (the jets are on the bottom..the needles are on the top...basic carb knowledge also applies)....NOW with all these things being equal, I dont lose any sleep over the reliability of my stuff...BJ

It starts with the right guy that knows what he's talking about and cares more about his reputation than just making a quick buck. BJ, I had you doo my 800Ptec motor the year before last. Put together as per your requirements. 2,500 mountain miles later it has been perfect and I have never touched it other than new plugs. I works for me. You'll be dooing my 860R this year.

QD- I remember your motor...and thats what I strive for...the 860R kit is a blast..call me when ready I will be OPEN!!-BJ

 

[SnowSnob]

I think I've pm'd BJ at least once a week all winter trying to dial in the twin pipes and he's answered all my annoying questions and is always helpful.

 

[kost-a-bunch]

use cast stock like pistons if your going to be doin a big bore,
I build a 830cc kit using cast pistons reliable like stock. motor gets fully ported and has a billit head with the package. we use the 07 800r airbox as well on all our 04-06 mods.
alot of the motors we had come thru the shop for repair are using a forged piston which smears when it gets to hot, piston clearance is alot more than a cast piston. plus they had no porting for a big bore. alot of guys think they can have it bored out and renikasiled throw a bigger piston in it and it is the best big bore around, NOT! maybe a tad better then stock but without a stock reliable piston.
call for info.

[WFO or go home]

Just keep in mind that there are a few good ones and a lot of bad ones you can get. Best thing to do is don't go overboard when going over bored (get it, LOL). Keep it simple so you don't have to spend your day under the hood.

Also, don't necessarily go by what the guy at the sled shop you go to tells you. They can tend to steer you toward the one option that they have tried without considering the other options that are out there. And don't buy in to every little hokus-pokus gadget that comes along, most of them are a waste of cash.

 

[Skadi]

Good info... ya, I'd heard that renikasiled pistons weren't the best route...

BJ, I will call. just been busy, busy with srping and all the work that needs to be done on my property!!

I am VERY good at following directions and definitely have more than your basic knowledge of the motor. I have done all my own work on it for a few years now. The only thing I haven't touched is the bottom end and the clutching. Well, I've messed with the clutching but only VERY basic stuff and it's always been with borrowed tools. Now that I'm committed to keeping this sled (if I do a motor mod I'll be runnin her for another few years!), I will be getting the tools I need to tear down the clutch on a regular basis to clean it!

Oh, and to whoever said the diet thing... ya, workin on that but if I loose too much I also loose the muscle mass that keeps me injury free and enables me to pull off some pure grunt lines!

Also, put a new top end in her for this last season. Increased her pep but I still want more!!

So it sounds like the three options are Turbo Als, BJs, and Terra Alps... Hymark we'll chat this summer and BJ I will call you once I get my initial spring push of work outta the way!! Thanks for taking the time to PM me!! Ted, I will look you up; seems like your name and location ring a bell, like one of my buddies knows you.... I'll track that bit of info down!


And Kenny, why ya gotta bust me out over instant messanger... go ahead, give me your advice!!
