1. compresion: all of our kits are at the apropriate compression such as complete top ends and withouht head.

2. crank arm: once you have taken the cilinder apart check the crank arm there shouldn’t be any play in the vertical motion. and paralel movement should not play more than 0,7 mmm

3. piston skirt: check piston skirt for damage if they’re is any trade it for a new one

#[[Compression]]: All of our kits are made with the appropriate compression such as complete [[top end]]s and without [[cylinder head|head]].

4. ports: if possible and if you have the tools touch up the ports so that they match the cylinderas close as possible . for a better flow of gases

#Crank arm: Once you have taken the cylinder apart, check the connecting rod on the crankshaft. There shouldn't be any vertical play, and the side-to-side movement should exceed 0.7 mm.

8. tuning/timing: slow down or retard the point of ignition by 1.8 mm to 2mm befot top dead center. change the spark plug for a grade equivalent to b7h

9.carburator: increase its size up to a maximum of 21mm, adjust carburation apropriately depending on what terrain or weather you are in such as sea lever temperature etc.. metrakit has at your disposition dellorto carburators.

10. lubrication: use synthetic oil

#Tuning/Timing: Set the ignition timing to 1.8 mm to 2mm before [[TDC|top dead center]]. Change the [[spark plug]] for a grade equivalent to NGK B7HS.

11. breaking in: it is recomended that for the first 300 km you do not go WOT this way your cylinder will las you more km and its also recomended that you increase your oil by 1% so if you are using 2% go up to 3%

#[[Carburetor]]: Increase its size up to a maximum of 21mm, and adjust the jetting appropriately depending on your altitude, climate, and other installed parts.

#Breaking in: It is recommended that for the first 300 km (200 mi) you do not go [[WOT]]. This way your cylinder will last longer. It's also recommended that you increase your oil by 1%, so if you are using 2% go up to 3%.

  1. Compression: All of our kits are made with the appropriate compression such as complete top ends and without head.
  2. Crank arm: Once you have taken the cylinder apart, check the connecting rod on the crankshaft. There shouldn't be any vertical play, and the side-to-side movement should exceed 0.7 mm.
  3. Piston skirt: Check the piston skirt for damage. If there is any, trade it for a new one.
  4. Ports: If possible and if you have the tools, touch up the ports so that they match the cylinders as close as possible for a better flow of gases. (aka chamfer your ports).
  5. Cleaning: Clean the piston ring slots very well. Grease up the ring grooves as well as the cylinder and piston.
  6. Piston: Important -- the piston has an arrow on it pointing to the exhaust port.
  7. Important: Bolt the cylinder head on in a criss-cross (like an X) pattern.
  8. Tuning/Timing: Set the ignition timing to 1.8 mm to 2mm before top dead center. Change the spark plug for a grade equivalent to NGK B7HS.
  9. Carburetor: Increase its size up to a maximum of 21mm, and adjust the jetting appropriately depending on your altitude, climate, and other installed parts.
  10. Lubrication: Use synthetic two-stroke oil.
  11. Breaking in: It is recommended that for the first 300 km (200 mi) you do not go WOT. This way your cylinder will last longer. It's also recommended that you increase your oil by 1%, so if you are using 2% go up to 3%.
  12. Exhausts: If you want more options we have a wide catalog and variety of exhausts . Metrakit is not responsible if you choose to use another brand's exhaust.

This is not included in the instructions:

During break in, it is recommended not to run synthetic oil. Petroleum based oil promotes easier wear for piston rings, which will allow the kit to break in better/sooner.
