Ok so I have a 2008 polaris outlaw 450 mxr that I snapped a rod on. I'm planning on doing the 540 big bore from thumper racing with trail ported heads and a bored and jetted carb with a 12.5/1 compression piston. The one thing that I just can't figure out is what cam I need to put in it. I was told that the stage 4 from thumper would be the best but I'm not sure and need some help with it.

Hey guys,
I’m looking for a good reliable company in the lower 48 states that can reflash my ecu on a 2019 Renegade.
I know Monster efi is good to go but they are up north. Their counterpart in the U.S., Wick it
Performance is not up and running their software yet.
Any others?
Thanks,

I have a 2015 570 that customer brought to me that wouldn't start at all. Needed a new battery, did that. Would start and die IMMEDIATELY after getting a battery. Checked fuel pressure was 20 PSI.. Replaced with a new pump assy. Now getting that good 58 PSI :).

The bike runs pretty good! Only issues I am having now is sometimes it'll die on start-up. Sometimes will bog when stabbing the throttle hard. Normal old man rolling on throttle running down road or trail its perfect, when its warm. Other than that it runs and revs clean, lot of power, able to pull wheelies and whatnot Lol. Some backfiring on decel when ridding and when revving in N and Park. Has cut off 2 or 3 times when going a good speed then slowing down somewhat rapidly, but started right back up. (Clutch system and all is in perfect condition, barely any wear at all.)

New battery, new fuel pump, bike IS charging, filter clean, everything looks in order! Only thing I have not done is change plug or pulled throttle body or injector or anything like that off to clean. Bike sat for a year or so customer said. But again, it runs pretty good besides those issues.

He also had another 570 that ALSO needed a fuel pump. Both sat equal time. The other bike runs absolutely 100% perfect. Even starts easier. Don't have a reason to put a plug or pull TB or injector on other one, runs perfect!

I have yet to 100% drain tank and add new fuel w/ TB INJ cleaner. Ive heard that stuff is just snake oil and does not work.. Think about it.... Gas in an EXCELLENT solvent.. High pressure fuel will clean just as good or better than high pressure FI cleaner, both forced thru injector, rail, and TB to clean it... JS.. Lol

Any ideas???

Picked up my 2019 Can Am Outlander 650 XT yesterday. Been a Honda guy for 25 years and what an amazing machine it is. Can't wait to have the break in period done to really get at er. Live on Browns Mountain in Nova Scotia, Canada. Looking forward to becoming active on here.

2004 400 sportsman cranks but wont start

Hey fellas,

I'm new to the site, I just acquired a virgin 850 HL that the engine was drowned. The upper case, rod, balance shaft, and relevant component were destroyed. The bike had less than 100 hours on it. I essentially got the bike for free so I'm looking to invest in the rebuild and really turn this thing into a BEAST with the financial liberty that I have without a note.
Thus far I have ordered the following. Used Cases, fluids, gasket sets, plugs, rods, & balance shafts.

The pros: the chasis, (everything but the engine) is essentially brand new. for the engine, the head & relevant components are good, crankshaft is going to get diagnosed/balanced when I take the used cases to be machined. The intake/throttle body appears to be fine as well as timing chain & tensioner.

The cons/what I don't know: how to test/diagnose the following: water pump, oil pump, bearings, timing.

what I need: I am seeking input/advice/recommendations on rebuild tips and tricks. Anything specific that I should be mindful of. Recommended performance parts/mods while I'm inside the engine. I would like to have as much input on the increasing performance and efficiency subject as possible. I am very interested in boring to oversized/performance pistons however I have not found much credible literature/input in these engines, nor overhauls being performed on them. If I were to bore the engine to a larger piston, what specific parts and mods will I need to upgrade to support this change? Ie. ignition, injectors, timing, air/fuel tune(r), intake/airflow upgrade. I'm cognoscente of the dynamics of modifying an engine, however I am ignorant to the education required to modify this engine. That's where I'm hoping you pro's and been around the blockers can lead me with good insight and recommendations for helping me turn my machine into a awesome unique machine.

In addition, could anyone shed some light on the "JE 970 Pistons"?

Hoping someone can help me out here. I just purchased a new 570 and had the dealer install the new Glacier Pro Plow to it. I got the unit home and can’t get the plow to detach. I’ve watched YouTube videos and it clearly releases right when you pull the red lever out. Is there something that I can adjust to make this work. I’ve had myself and a buddy both yanking on the thing and it won’t budge. I can see when I pull on The lever it is moving the catch bracket but it still won’t release.

Anyone else had issues with this?

Thanks!
