t5 malossi carb size

[ducksta]

Running a 30mm dellorto on my t5 172 reed valved engine, on speaking to a reconised tuner today he recommended to use a 26mm any body else use this size and whats the feed back

[Yanker]

Erm no: Correctly jetted the 30mm will deliver the fuel that the reed dictates: never too much and never not enough with the 30mm (that is what mine has without being ridiculous on fuel consumption ie. 60-70 miles on a tank). What is the rest of your set-up and what is the tuner's logic/explanation?

172 malossi malossi reed 30mm carb fast flow tap ports matched etc by chislespeed revolver exhaust 22 tooth clutch

[ducksta]

Tuner reconded 26mm will give better fuel and mid range only losing about 2mph on top end

Why not go for the VHST ?

Why not go for the VHST ?

dont know out about them mick, i could just swap all the bits into a 26mm delly

[mick1]

VHST are the flat side. which is the preferred choice nowadays.
I'm looking at fitting a Mikuni flatslide on my PX, again MIkuni's and other carb's seem to be gaining favour over the Dellortos

[ducksta]

do you still have the 28mm delly if so would you sell that m8 pm if yes

vhst carbs are a lot more expensive than the phbh range.

I think phbh`s are on the up - lots of TS1 and RB motors running them now - easy to set up and cheap to rejet
