Cutout acceptable?

[Glynn123]

What's your opinions on cutting out the airbox lid Calum? I'm thinking of doing this myself, however maybe abit lean on stock carb with a full system and 250 main jet?

[Calum]

@glynn123 So I think it's absolutely criminal, however Rob @ Yamaha Skellerns Cheltenham tells me that these bikes are massively restricted by the air box and he encourages the cutting of them for performance sake. As said, I just run a pod filter as it means you don't butcher an OEM part.

@calum mines already slightly butchered haha, I have my snorkel removed so was thinking of just elongating the hole across, not cutting the whole lid, however I might just leave it for this summer.

[Calum]

@glynn123 I'd just cut the whole lid off if it's already been cut.

Seen on another forum that the snorkel off other DT's fit and they aren't as restrictive, I think I saw a guy with a DT175 one?
I guess the DT200 or 230 would fit as well

You might want to keep the box/snorkel if you plan to go off road a lot, through fords etc, as cone filters and the like are not so great at keeping water out of your engine

[Calum]

@fused True, but if the bike is purely used on the road then it will be fine, plus ssaves you buthering the box for more performance.

My wr200cc/dt125r hybrid engine runs with lid cut off. I ran it also with the 125 engine. You just need to jet accordingly.
