Scooterotica

I have a standard Rally 200. The only difference from original is a SIP road exhaust and a 122 main (it may well be dropped to a 120).

I hear of people drilling holes in the airbox. To my eye, I can't see this making any material difference on my set up.

Any thoughts please?

I have same pipe & 120 main on mine with drilled filter... think from memory I drilled a 5 or 6mm hole in the heart shaped area on underside of filter (where it sits over the main jet)...

Do as likes this piccy m8

Thanks for that. Will that allow me to run a very slightly bigger main jet?

Probably, try it but do some plug chops m8

Cheers. I'll give it a go.

Finally got around to doing this. I must say it does work. More torque throughout the full throttle range.

Next thing to do Paul, is put a Malossi 210 top end on. Plenty of torque right the way through the rev range

Then whack a 60mm Pinasco crank in it

Still on the original '73 piston believe it or not. I did treat it to new rings before I went to Europe on it last year though !
