* First torque: 18 ft-lb (24 Nm)
* Second torque: 22 ft-lb (30 Nm)
* Final torque: 26 ft-lb (35 Nm)
It is important to follow these torque specifications in order to ensure that the head bolts are tightened properly. Over-tightening the bolts can damage the threads or cause the head gasket to leak, while under-tightening the bolts can allow the head to move, which can cause damage to the engine.
Here are some tips for tightening the head bolts on a Honda Recon 250:
* Use a torque wrench to ensure that the bolts are tightened to the correct torque.
* Tighten the bolts in the proper sequence. The sequence for the Honda Recon 250 is as follows:
1. 1
2. 3
3. 5
4. 7
5. 9
6. 2
7. 4
8. 6
9. 8
* Tighten the bolts in three steps. First, tighten the bolts to 18 ft-lb (24 Nm). Then, tighten the bolts to 22 ft-lb (30 Nm). Finally, tighten the bolts to 26 ft-lb (35 Nm).
* Be sure to use new head bolts when reinstalling the cylinder head. Old head bolts may be stretched or damaged, and they should not be reused.
