300 mile review

[Winder_506]

I ran into plenty of 850's last year and most disappear when a winder or thunder cat show up. 850's are not even a challenge and they know it. Hygear makes a dual rate center shock spring that you can order for your weight, nice improvement from stock specially if your a husky boy. you have 300 miles and been on the snow for 5 weeks? thats one day ride.

I’ve been out 3 times since we got marginal snow to go. Can only do small loop around the high country of our trail system. It would be a lot of circles to get 300 miles in one day. I’ve done 256 miles in one day and that was way to much. We’re more 30 for 30 kinda riders

May not be competitive vs a tuned sled as they shouldn’t be, stock tho is a race, 660’ Is the 850’s. To 100-110 mph they are no slouch and the boys here know how to make em go. All sleds have their Niche

It only hit the limiter be for I had it studded with the pipe. It would bounce it once from a dead stop start then pull through to 9-9150 rpm. The next time it sees snow it will Have TD multi map dash flash and all the good stuff with it. I was just surprised that a trail pipe would damage the engine. A high flow race muffler even from mbrp makes 24hp the trail is only 4 and doesn’t say a tune is required to run right on their web site

BTW- you probably know this but if your running only a this MBRP can, and you're running 9150 RPM, you're way past the peak HP on the 998.
Load clutch with weight so it runs 8800-8900 and the motor will be happier AND the sled will be faster.

I can tell you from experience if a muffler is suppose to make 24hp all by itself,more than likely its bull,I even had the sandale full 3" and it did not make 24 all by itself,and you sure did nee a tune for that bad boy,bad boy in a good way. If your muffler is not stock,and you have a bone stock winder,pull it off as quick as you can,before you do damage,just for giggles,reinstall your stock muffler,and run them doo boys again,i bet you will be surprised.

Yes I’ve read this. Like I said sled is going to the shop for the dash reflash and all the supporting mods for the big tunes. When I tested belts on Saturday, the same spot, same distance and back to back runs with Yamaha belt vs XS825, the Yamaha belt was 9150 at the light at 106, 105 and 106 consecutive then the XS was 8400 rpm at 106, 106 and 106. Same distance and back to back runs, 750 rpm difference at the same speed

Yup. Should tell you how much the Yami belt is slipping. The XS belt is not slipping anything like that. Additonally, if you check the clutch temps, you'd find the clutches cooler running the XS belt cuz it's not slipping. IMO, run the XS belt and work clutches to pull hard at 8800-8850 and build to 8900-8950 on long hard pulls. Sled will be faster all the way around.
LOTS of good clutching advise here on TY!!!!

Hi,i went on there site,looked at that muffler and listened to it run,it looks very stock,and does sound slightly deeper in tone,have to say,it is one of there best looking mufflers to date. But once tuned you will be good to go. MBRP used to have some very loud pips/mufflers and they mostly just made noise,this muffler is very will made from the pic at least,good luck with it.

I believe this muffler is the quiet one from MBRP(in my backyard so know the gang well), no need for tune.

That being said, not sure why anyone would want a muffler like this. When most guys want HP and STOCK sound, and we now have wonderful STOCK MUFFLER TUNES avail.

X2 RockerDan. For close to the same $, you can get a SM tune that will really make a difference when you poke the throttle!

Add to that no visible mods. A sleeper, lol

Because it sounds way better then stock and it’s not obnoxious loud like a race can. Exactly what I wanted and it also flows good to get full advantage of my tune bundle.

My '20 was off by at least an 1/8" on off-set....

(1/8" off) you mean out of spec by 1/8" or 1/8" off from what you prefer?

The 8 lb weight loss isn't bad either.

A little greater than 1/8" away from the Hurricane bar. So depending on the degree of +/- , quite a distance off.

I think it's funny the 850 guy may have actually convinced himself he can run w a Winder! He's in for a rude awakening lol. Go get 'em!

My brother thinks his mod 850 would walk me on 270 hurricane ss tune in a 1320 I said anytime lol
