Racing Engines

The first step to create a racing machine that is lowering the engine block as shown, then separate the lower block and the block and then clean all  dirt and crust residue.
4-stroke racing engines make it rather difficult. Due to the distance of the four bolts are too close to the cylinder liner or boring. So, it's hard to bore up greater choice and be limited to change.no sliding bolt diameter piston engine, piston worn largest measuring only 54-55 mm. That, too, was thin and boring machines heat so fast. But to be able to outsmart this problem, Honda Legend Honda 100cc or duck could adopt Honda Sonic piston with piston diameter 58 - 60mm. The trick is to disassemble the entire machine, which means that the crankcase also opened.
After that, lathe parts crankcase mouth ass facing the cylinder block as much as 3mm. Crankcase section turner so boring it must only be entered

Then go to the cylinder block itself, before installing or specify a new piston liner, must say to the turner, Papas explain the block with a screw loose have a distance of 2 mm blocks. Furthermore the second step, a lathe within the block more tightly. Ask the turner to equalize the diameter in order to fully round.

But usually turner already understand because it is experienced. Well ... then just plug the new liner with a diameter of 60.5 mm, and then stay put piston. Want to size 58 or 60 mm, just specify your needs. After all of the above process is carried out, of course, jumped compression and power becomes greater, due to high compression. So it would be nice if using fuel with higher octane number, to avoid ngelitik because knocking. Usually my racing friends using Pertamax fuel, the price is more expensive than gasoline pertamax usual. if
I not have the money, I mix it with regular gasoline pertamax .. hahaaa
