The forged es**rt screamer motor is coming along nicely now. This week we torqued/stretched the rod bolts in the rods. Im my opinion it is the only way to do the job. We also cc’d the cylinder head to work out the compression ratio of the motor, put it this way it is looking well!

We will fix almost anything. A little job for a friend today. This fmf exhaust off a KTM250 EXC had seen better days. I started by pressurising the exhaust chamber to 40psi and heated the dents heavily. This pushed the pressure up to a nice 80psi and along with the heat the pressure took some really nasty dings out. Giving rhis exhaust another lease of life.

Nice easy job this one. First up was tomake a stainless steel bush for this porsche mecan turbo. It is a common fault they wear out and cause a metalic rattling sound. The rebuild kit bought had the wrong size bush to seat in the turbo housing. The bush was made it is is a press fit. But if you freeze the bush and heat the turbo housing it will drop in. The hole was rough drilled and final machined withba reamer. This ensures it is the correct size andthe finish is on point not to bind with the wastegate shaft.
