EC300 2008 FEELS Weak help

[Azlam denis]

Soo i got a 300 2008 it doesnt hit the power band and i mean it doesnt raise my front wheel up not even in 2nd gear or first or 3rd i dont know much about this bike its my first bike it goes quite slow i tried a HUSABERG 250 2011 one ride, it was mad fast not like mine i feel it weak the rear sprockets its 48 or 49 and front its default
What could i do to make it feel better pr maybe i dont know to ride this bike on its style i feel it weak it doesnt explode like a normal 2t bike it doesnt raise the front wheel up not even a little..
And it doesnt rattle like a strong 2 stroke it rattles weaker than other 2 strokes

Lots of questions . Does the bike rev up when it’s sitting there ? I just went thru something similar with a guy on here and his power valve linkage was messed up .

 

[Hellcat]

These bikes don’t have the big hit you’re looking for like motocross bikes . But it should pull the wheel in 2nd if you want it to. These are woods bikes . In woods you want front wheel on ground . lol

Well it's hella old so anything could be wrong with it. I've just sold my 2007 and it is going strong.
Obviously after service the consumables like plug filter and repack the muffler that can collapse. Check compression. Power valve movement and the carb clean as blocked jets are no fun, or are ovalise needle jet.

It has compresion but it feels soo weak it doesnt pull the front wheel i expected more because its a 300 i was on that enduro 250 hsbrg and it was mad powerfull not like mine mine feels more lazy and the valve opens up only at 9000rpm like at the top of top until there it feels weak running 25ml of oil at 1 liter 25 to 27 ml putoline mx9 i expected way more from this bike

The bike is in normal behavior doesnt rev up without giving gas it stays at idle but it doesnt rattle too much like a normal 2 stroke

You are pretty sparce with details. In your other thread you make it sound like you use it on the road. I'm guessing Europe to do that.
Putting on my psychic hat, did it come with a black pipe fitted? To meet euro emissions they have a pipe with a Cat.

NZ ones get shipped with both pipes but the CAT pipes are never fitted, usually they don't get seen by the owners. I got mine as a spare and fitted it one day.
It ran like a sad 125.

Why and how do you know when the pv opens?

 

[Azlam denis]

It does have the black pipe default gas gas i removed the spark plug ran it without gas opened and tried bump starting it and the engine was clogged with oil and fuel and smoke it does run better now it opens the valve and it is more agressive now but i think if i would change the pipe with a fmf one it would be even faster!

Ok I had to guess that. Details help.

There is a ISDE model with black pipe and no cat. But not common.

The Cat is located in thickest part of pipe. It is like a painting mask filter on a flat plate. If you take the muffler off (check perforated tube hasn't collapsed and repack it with proper exhaust fibreglass after cleaning out the holes).

Poke some welding wire or similar up the pipe. If it hits something then you need to get rid of that.

I cut mine out by cutting and rewelding it.
So so much better. Having said that the slightly beat up nickel plated pipe gave it a bit more zap.

Oh yeah. Don't leave it idling. It's a competition 2 stroke not a CB500.
