I've heard both yes and no on a 300. I put one on my 300 and couldnt tell a difference. Put it on my 250 and did notice more bottom end.

Why do oversized PV covers do what they do?

While on the subject, who here has fit either a larger cover or a cover spacer to their older ('01) 250/300? I was looking at mine the other day and it looks as though I only have about 10mm between the stock cover and the lower coolant hose. My radiator is straight, so I'm curious as to how I might make a PV cover spacer work on there... I'll take all the bottom end I can get no matter how minimal the gain (so long as there is some gain!)

How close is your coolant hose? How deep is the cover you are using?

Thanks for the picture. I might just have to loosen the radiator mounts/ hose clamps and give it a little persuasion to make room, I don't know why my hose is so much closer than that.

If too close then put these on the hoses. They work great!!

Same boat here with my 00'. The radiator hose connection seems to be in a different location than other bikes. There's very little clearance there.

Pics of clearance on my 00'
Here's the limited clearance on my 00' EC250. After seeing this on my bike I don't feel they're an easy bolt on to all bikes. A person could relocate (fab & weld) the outlet on the radiator to gain more room unless the covers fit in that limited space. I know the billet spacer plates that move the cover out won't fit in there without radiator modification.

and what were your result like?
This company describes a volume powervalve cover in a way that puts me off buying it
http://www.trialendurodirect.com/products/15_17/TRUSTY_Big_Volume_Powervalve_Cover_140.html
For me I would be buying one for more power at the bottom end, not a more docile bottom end.
Anyone know if this really does make the low end more docile whilst other brands make the bottom end more torquey?

Perhaps they mean more docile because you can ride at lower revs without stalling? That was what I noticed - still the same when you twist the throttle

Its a tough one to call. The claims are that they give more torque, or more grunt, however I feel that it also comes at the expense of responsiveness. This gives more of a tractor like feel that will chugg off the bottom end a bit better than stock. Some would say tractors are docile.
Effectively, all that is happening is that you are increasing the volume of the pipe for the duration that the PV is closed.
