New carb & Sports Airfilter For Gilera Runner VXR 200

Dow49 · 07-01-2010, 18:27

Hello, I am presently customising my 2004 Runner 200, I have just bought a Malossi big carb kit PHF 34mm MHR and a few questions arise, for anyone out there.
First will I need to change the jet and if so what size jet will give me the best performance.
Also will this new carb along with a carbon Scorpion exhaust
( Already Fitted) give me the same performance as the original standard Runner carb, airbox & exhaust.
Before starting to customise the scooter last summer the Runner's top speed was 80-85 Mph depending on the wind conditions & fairly quick off the mark.

Malossi has provided the carb. with a god basic setup.
But you can experience that finetuning the jetting of your carb will provide you with better performance.

Thanks,as long as the new carb gives me a similar performance thats fine, I just wanted rid of the old airbox spoils the look of the runner.

Hi Dow49, which tuning parts do you have on your engine?
in my opinion phf34 it's a carb which can give improvements only if you a 210cc cylinder and the head has been modified with slightly bigger valve to allow a bigger flow inside the combustion chamber.

if you're installing it on the original engine i think it's hard to get better performance compared to the original carb...

Thanks for your reply,
I am just putting the new carb on the old set up so far,as long as I can get a similar performance .The runner is my old scooter I am just sprucing it up a little and using it as my summer scooter,gone abit over budget at the moment so this set up will have to do.

Hi, i've also a runner with 210cc (malossi) and i've tried many settings on the transmission (i use for racing only on karting tracks).
i've never tried a system with two type of contrast springs so i can't say much abt this idea.
regarding the clutch i can tell u that, on this type of engine, is not really worthy to replace it. the original one (as long as it's in good shape, well balanced and not worn out) with harder springs works just fine even for racing. you may save that money for buying something also...

in my opinion the best contrast spring is the Pinasco one equipped with the spring slyder of the same brand. it allows u very good acceleration and stability of performance even after the transmission is heated up.
furthermore if u also use the pinasco variator (much better than the malossi one) you'll have improved acceleration with a little increase also in maximum speed, since it allows a little longer ratio.

the above is just from my experience...
