Could anyone tell me the difference between the Picco P7R-EVO2 & Picco P7-EVO3? I want to buy one of these for my Hyper 8.5 buggy?

Anyone?

I'm sure Supertib and/or Integra will chime in shortly.

Be patient.

hi im a picco guy. the diiferences are the evo 3 has a lil bit different porting in
the block to get that better fuell milliage that the 2 lacked and the crank isnt as crazy so over all the 3 is smoother but still
puts down the power. If i were u look at what your goin for and what kinda track ur racing on. if u race on smaller tracks
then go with the 2 but if u run on big tracks go with the 3.

well said crazy 8t you hit the nail on the head....basically its all timing #'s that is the difference....o and the non fall apart head..(evo 2 heads like to rattle apart after a couple gallons)...so i would go with the JPX version for the price and the head that wont start rattling after a gallon or so.

Thanks Intergra. Ya idk why the heads do that but every picco head iv ever had has done that so i just take the head off after break in
and put an O.S Rocket racing head on them.

EVO 2 and EVO 3 are identical... cranks are the same, block porting is the same, sleeve porting is the same...the only difference is the EVO3 has a shim under the sleeve to slightly raise port timing....

i tried the Fatt Head from Trinity...HOLY CRAP it weigh's a Tonne...ill stick to my stock JPX head thx. [sm=lol.gif]

anyone else make a head for the picco's? I wouldnt mind having one either, but not crazy about crazy nut, or the trinity.

JPX version ?

Is it a must to seal the carb?

IMO yes....strange things can happen if you don't.....i used to play devil's advocate with which carb i would seal...but no more...i just seal them ALL and be done with it.

+1 I seal every engine I have.....eliminates headaches.

Can I use this to seal the engine? http://www.amainhobbies.com/product_...ducts_id/25728
