A Brief Discription

[lotus791]

The new line of GRP engines  make plenty of  torque and rpm  .12 mins + on a tank of fuel is a reality.i have ran  1 and 1/2 gallon of byron 30 through mine at the min  straight out of the box no shimming .the power is very smooth and can dance when you want it too.
i stripped the engine as i would at this stage to check bearings and rod  etc. bearing like new  con rod like new   crank pin like new . very impressed . the exhaust set up with the new fls  is  excellent one less rubber and 3 springs  that i now dont have to worry about .
engine temps are quite cold  compared to other engines  due to the size and design of the head .
