Is my XT600E restricted

Hi folks,

I've just bought a 2002 XT600E 4PT model with 43BHP and it's pulls with noticeably less urgency than a DRZ400 with 49BHP.

I ran a Redex treatment through it at the weekend and there is some improvement, but still not like I would expect a 600 to be.

How can I tell if my bike is restricted to 33bhp?

Thanks

Probably restrictors in the inlet and exhaust - not sure of the details. I used to have a restricted XT350 and the restrictors were a pair of narrow sleeves in the inlet manifold (easily sorted) and a heavily-baffled silencer (much harder to do). But remember these are not fast bikes, and I'm pretty sure a damn sight heavier than a DRZ. Combined with 6 bhp less, that could account for the lack of zip.

I consider the performance of mine to be 'modest'.

The drz400 is a lot lighter, so even if the bikes had the same hp, it would feel a lot faster.

Dont think youre restricted, you could get it on a dyno to check if you want.

The 600 is all about reliability, so everything is bigger, heavier and more sturdy. And the engine puts out fewer horses than other bikes in the 600 thumper league.

My hopes are up for ya, It could be awesome for you to gain som free ponys.

I wouldnt worry about it, my TTR 600RE is slower than a KDX 200 but atleast you dont have to put two stroke oil in it.

I had the same feeling about mine,
I have a super trapp exhuast with 6 disks. When I took the cap and disks off it runs a lot better. mufflers can be restricteive! the more air you can get through an engine the better. Think of an engine as a air pump.

Yeah, and they are jetted a tad rich (2003 version) even with the lid of the airbox of, and the exhaust opened up a tab, it was just a notch on the rich side. I guess they do that to make them run cooler.

Thanks for the all the replies everyone.

I'm not bothered about power too much, the bike is powerful enough for what I need it to do. I'd have bought an XT660 if I was worried about power, but I wanted the simplicity and hence reliability of carbs and air cooling so I can get well off the beaten track without worrying about holing a radiator or having electrical gremlins.

But that said, if there is more power to be had from the bike, that is always nice to have and makes life easier and more fun when on tarmac.

I think I'm going to get a K&N filter for it. Is there any points of restriction in the standard exhaust which can be removed?

Theres a screw in the end, out with that and you can take the "lid" of. If that's too much sound for you, you can cut of the inner pipe of the lid, openening uo the flow.

Hard to describe, but it all makes sence when stand with the parts.

You wont gain a lot of hp, but it woke mine up a tad more in the low rpms.
