hi guys im in need of some help .

My bike today has just loss loads of power only l letting me get about 30 mph . After riding 4 miles I got to work and the bike stooled and cut out . I then noticed the exhaust was glowing red where it conects to the engine. The bike also has been popping out the end can. The bike still has compression as it still kicks back when I kick it over .

The bike is a 2000reg te 410 husqvarna

any one have any ideas what this could be.

Thanks

Hm, weird one that. Air leak around carb manifold? main jet fallen out?

Any warning or did it happen suddenly? any funny mechanical noises prior to it happening?

How can I deal with that or am I best taking to a garage. The engine has got a weird noise over last week some one told me it could be tappetts and some one said could be the top end. The noise is like a rattling noise . But I would guess if it was top end out pistons it would not even start.

Im thinking something either exhuast port/valve or soemthing maybe with air and its not getting enough?

Confused

Could it be no water in raditor as I have not checked that in a while. And its over heating ?

Yeah valve/timing issue after you said popping which I assume is back fire.
Back fire is unburned exhaust gasses which ignite in the manifold as a result of bad timing or faulty valves. Also explain red exhaust if the mixture is igniting in the manifold backfiring as opposed to firing in the cylinder.

If your not mechanically minded this is a a job for the garage,
manual and tools needed.

I think the bike is running very lean, if you keep riding it it will melt the piston and cause lots of damage (If it hasn't already) This would cause the fact bikes and the redhot exhaust. Check of leaks in the manifold and check the air filter is secured properly and not damaged, I would also be tempted to whip the head off to check the piston.

How can I check the petrol vale to see if its that. I have taken carbretters apart before guessing its in there.

What does lean mean?

you know the perfect ratio 14.7:1 if its higher than that its running rich if its lower then its lean.

Basically the air fuel mix, to much fuel its rich and to little and its running lean.

The plug looks fine. Just checked it.

If I took this to a garage thinking its one of the above anyone know how much it will cost ?

Thanks for every ones help here.

Sounds like a buggered exhaust valve to me. Get it compression tested at a garage.
