Advice 1: How to boost a motorcycle engine

To boost motorcycle engines developed and applied in practice a variety of methods. Some of them can be applied in a home garage, the application of some is possible only in specialized enterprises for motor tuning. Some methods are characterized by their relative simplicity and low cost, others are very sophisticated and can cost much more expensive motorcycle.
Instruction
1
Before you boost any engine, remove the set power limiter. Without this process forces loses all meaning. Often, instead of the power limiter includes a maximum speed limiter. Delete it, too. After forcing the engine, most likely, the motor will develop maximum power and torque at higher revs.
2
Chip tuning is a reprogramming of the engine management system in order to develop higher. In practice it seems simpler to force changing control unit injection. In order to do it yourself, you do not need extensive knowledge. Purchase this unit for motorcycle in the bike store, selling tuning kits. Installation instructions will be included with the product. This method of storage is suitable only for modern motorcycles of foreign manufacture.
3
If the motorcycle has carburetor the power supply system to boost a wide variety of methods. Standard carburetor hone, increase the diameters of the Windows, nozzles, change the settings. Or install a dual carb, twin cylinder engine. If you have the opportunity to purchase specially designed sports carburetor, buy and install it. But not all models of domestic motorcycles you can choose the right model.
4
A forced exhaust system of the engine is also worth it to upgrade. Install flow muffler, purchased the same bike store. More serious tuning is to install a completely new sports exhaust system. For her installation in the engine, you may have to contact the tuning firm.
5
Turbocharging is a serious way to boost the engine. Not all motorcycle engine tuning companies produce ready-made options. Even in the presence of kit-the kit turbocharger refer to the experts to install it on the bike.
6
Tuning of the cylinder-piston group of the engine is forced to increase the compression ratio of the engine. To do this, change the combustion chamber by milling the pistons, change the stroke of the pistons by installing a sports camshaft. Adjust the timing and angles of the ignition setup for the new compression ratio. Note that in many cases, to install a turbo or compressor on the engine need not increase, and the decrease of the degree of compression.
7
In addition to these, purchase and install aftermarket kits, without which none boosted engine. This air filter zero resistance, racing camshaft, capable of operating at high and ultra-high speed sports ignition system, and more. All depends on the extent of the forces and financial possibilities of the owner.

Advice 2: How to speed up the engine of the motorcycle IZH Planeta

Capacity of outdated two-stroke engine of a motorcycle "IZH the planet" if you wish, you can increase, even without causing serious harm to the resource. This method was actively used by Soviet athletes in the 70-ies and 80-ies of the last century to prepare the cars for competition motocross and a multi-day rally.
You will need
  • mechanical workshop medium level of equipment;
  • - good engine IZH Planeta
Instruction
1
First Polish the cheek of the crankshaft and give the body hair a streamlined shape. It is a necessary attribute of the training of any two-stroke motor. Then a blow of steel SOHMA or ZOGGS new cheeks of the crank chambers with an outside diameter of 133 mm. Balancing selection under the lower connecting rod end will decrease to 54.5 mm. to compensate for the Imbalance by making holes 28х20 mm from the bottom of the cheek at a distance of 38.5 mm from the center. Hole close duralumin cap.
2
So the engine is easily spun up to high speed, lighten the crankshaft. For this, his facial cheeks mill so that their diameter decreased from 52 to 40.5 mm. the hole cap of duralumin, zaccanti and Zapolarye them. Upgraded so the shaft balance. All the changes improve the speed of the motor at the expense of smoothness.
3
To improve the ride and tegometall engine is the crankshaft change crankshaft bearings. In this motor they are a weak part and fall apart quickly. To address this shortcoming, the inner rollers brand 2505К replace two caslifornia to a thickness of 9 mm ball bearing 6205 brand. Install them to the crankcase, heat to 100 degrees and hot insert it in the crankshaft. For supplying lubricant to them will protocide a groove depth of 1 mm in the crankcase at a distance of 17 mm from the ring-stopper of the outer bearing.
4
Seal the crank chamber from the left and right side of the omentum from the "Java 638". Under the left oil seal of steel grade 45 carved ring on the crankshaft and Polish it outside. With the right hand press into the crankcase roller bearing 42205, caslifornia to 10 mm and install the cover with gasket from IZH-Jupiter. Maloprodaja channels from the crank chamber stop, and instead install two plastic tubes with a diameter of 4-5 mm for the oil supply.
5
Replace the carb. Soviet athletes put "Mikuni" or 62Д from Izha Planet-Sport. Or famous for their reliability on rough terrain carburettors FS-250, FS-500. Currently, for two-stroke motorcycles you can pick up a more modern tuning the carb.
6
To improve the operation of the ignition system alternator replace the modern model of the motorcycle "the Owl". If you want to increase the power at high revs, order specialists the production of a new electronic switch. The result will be a significantly more powerful motor with twice the resource.
Useful advice
Forced engine consumes more high-quality fuel with a higher octane number and a special oil for uprated engines.
And engine tuning is more sensitive to the timeliness and quality of maintenance.
