Hello, I have a problem with my Bombardier Outlander 400 XT. I can accelerate over 50 km/h on a straight path. In neutral position when I give gas he seems hesitant. When it's been a week since he hasn't started it's hard to start

ideas?

Muffler may be plugged up.

How can I verify if this is the problem? I put my hand out and I feel the exhaust coming out

If carb'd, carb is prolly dirty/in need of cleaning/rebuild

If EFI, fuel pump may be weak

Which is yours?

I have already checked the air filter and cleaned. Indeed, it is a carburetor system.

Update:

I changed the spark plug and clean carburetor and still have the same problem ..

Going up a hill I reach 35 km/h and on a straight path maximum 50 km/h (top speed).

When I start it makes a weird sound and when I release the accelerator too.

I have the impression that it is about a problem of clutch is this possible ??

Update:

I took off the clutch cover to see what's going on there.

Can the strap be so stretched that it will slip out?

I did the test with the rear wheels in the air in HIGH mode and easily reached 98 km / h.

I am waiting for your answers thank you very much

So without any load or drag on the driveline, the bike gets on up to speed?

The belt doesn't look bad at all, but perhaps it's slipping under load, limiting your speed.

Do you perhaps have a brake caliper dragging?

Exactly, without force on the drive it is able to pick up its speed. The brakes everything is correct and check.

Might just be me, but going by the pics I'd call that belt your new spare. It could just be dirt/dust between the cogs altho it looks like cracks to me. Also notice the flat spotting on the cogs, excessive IMO.
Best way to find cracks is remove the belt and flip it inside out and inspect.
Again, just my opion but you need to remove both clutches, clean, inspect and service as needed. They have quite abit of visual belt dust. (You need not remove entire primary clutch, just the outer assembly).
Be sure to also inspect the helix and outer bearing on the secondary for smooth turning. I recently replaced both on my own bike due to wear.

I ordered a new belt, the old one is very worn.

I'll will do the maintenance of the clutch.

I hope to solve my problem. I can only drive at 50 km/h...

Stay tune for update

I will receive my new belt tomorrow. I checked and cleaned the right part of the clutch.

For sure the clutch on the left, the screw is unscrewed in which direction? Left? (Same as original Bolt)

Because I did not succeed in unscrewing it my impact battery is not strong enough it would say.

On the old carb'd 400's, the primary bolt is reverse thread.

Clockwise to loosen it, counter- clockwise to tighten.

So you can confirm me that primary Bolt is reverse thread.

My model : Bombardier Outlander 400 XT 2008 (carburetor)

I believe all the single cylinder models are rev thread.
