    I’ve got a Hi-PER 2 pro engine, you are correct in saying the only difference is the vacuum outlet on the side of the cases by the reedblock, everything else is the same.

    If you have a none pro set of cases but need the vacuum outlet for the fuel pump used on the newshape Runners you can punch it out of the old cases from behind, drill or punch out the blacking cap in the hole (depends on how new they are, some have the hole and a blacking cap and the earlier ones have solid aluminum there) and press the outlet in.

    the most important differences between the Hyper 2 and the Hyper 2 pro are this:1) the first engine is used on the air cooled models like zip 2 stokes (not SP) typhoon and nrg power air cooled 2) the second engine is used on the liquid cooled models like zip SP runner and nrg power liquid cooled 3) the Hyper 2 hasn’t the rear disk brakes and the Hyper 2pro has it (not the zip SP)

      Hy.I have a 1995 Piaggio Typhoon.My transmission overheated and broke.
      Now with this ocassion,i want to swap the old engine with hyper 2 Water Cooled and disk brake.
      Wikipedia says that any Hyper 2 engine since 1998 can be water or air cooled (depending on the version it is built as) the same beeing true with disk brakes.
      I can all the engine can be converted but not all have disk from the factory.
      I also need to use a bigger wheel to have space for the disk.
      Is the disk hydralic (like the front) or cable ?

      Thus,what engine do i have to search for Hyper 2 or Hyper 2 pro (is second i heard are used only in race scooters thus is very rare and expensive even used) ?
      Any engine since 1998 used on NRG (wich also has factory mounted bigger wheels) or specificly search for Hyper 2 PRO version ?

    I’ve had two old hi-per engines, but they looked different where the large oil belt pulley sits. They had a stud just like the newer engines?

      Oh wait, i guess thats where the water pump shaft comes out?

      Haven’t had the pleasure of owning a LC version.

      Hi Mark. Fixed your Gilera yet? Does the engine rev up without you opening the trottle?
      If so, you have a crankcase airleak, not a faulty carb setup.
      Often, the cause is the crankshaft sealings. Try spraying starter fluid / carb cleaner ie towards the sealings when its running before it bogs. If it does’nt bog when applying starter fluid, its the sealings.
      Good old mechanic trick:)

    Hi, I’m looking at the latest Malossi torque driver (the red one in aluminium) for a zip sp LC, it states only for the short crankcase, which one is this in your photos?

      Mine is the upper crankcase in your pics, so why do Malossi refer to a short crankcase?

    Hello,

    Great read, but i have a totally different question i hope you can help me with.

    Do you know if the Piaggio Typhoon 50cc and 80cc engines are similar, as in can they take the same parts, like clutches, gear wheels, crank?

    or is it a totally separate beast altogether.

    Hola

    Voy a ajustar las informaciones.

    Hiper1 Tiene los canales del carter mas grandes,en la toma de admision donde esta la caja de laminas el hyper2 es mas pequeño,un tope que no se puede desmontar.
    Por lo general son iguales,pero la version hyper2 cumplia la directiva euro3,por lo que viene mas limitado en todo.
    En mi humilde opinion,el motor hiper1 de runner o energy es el motor mas potente que se fabrico para 49cc. ademas es una perfecta base para preparaciones a altisimo nivel,hoy en dia en los campeonatos italianos como malossi cup o polini cup,el 70% de las motos son zip sp1.
