today, i start working on the engine, I have make a 100.25 cylinderblock, as I will use the 100.19 mm ROTAX RACING factory pistons, ( that pistons are available for puplic, price 9600 SEK 3 pistons incl piston pin ) the pistons are forged lightweight and have a compression ratio 9:1 manufactured by MAHLE.

the balancershaft is lightweight as well, from ROTAX RACING 5800 SEK, but a local machineshop can do the work as well

next to the balancershaft, you can also see the ROTAX RACING lightweight CAM timming gear

all parts are also used on the rotax racing factory engine (Lemoine, Zapata)

the stock crankshaft has been micro polished by a motorshop in Gotheborg

the project is successfull done, accelleration and topspeed is absolute unreal

i had to change the prop 2 times, to get the bot from the 9000 RPM Limiter

now max RPM is 8860 with extrem pull in the midrange, I m using the Impeller of the Dark Dog turbo RXP now, and I reach 120 RPM more the the urbo rxp,DSC09943.jpg
