A Tacho is not required. Limit the speed on the straight to speed that can be obtained through a medium corner.  In other words, do no exceed the speed at which you left the corner before the main straight.

Allow the engine to rest for 5 – 10 minutes between each session.

Check all nut and bolt tension at the end of run-in


During the run-in period, the engine will vibrate more than normal. This is normal when engines are run at low revs.  

IMPORTANT - Avoid revving the engine to the rev limiter. Continued use of the rev limiter will damage the engine.  The engine has an inbuilt limiter at 7,100RPM.  At this limit, the engine will stop accelerating and make a noticeably different sound. The engine can not rev beyond this.  The engine however is not designed to continuouly use the limiter.  If the rev limit is achieved;

* Reduce acceleration to avoid high RPM

* Change gearing
