7. CAR SERVICING 7.1 FILTER SERVICING Oil Ch an ge - We recommend changing engine oil every 10 hours. To do this remove the large oil pipe from the bottom of the oil tank, located in the right-side pod, underneath the engine cover. There will be a small amount of oil left in the engine, to drain the last bit of oil remove the 17mm sump bung on the side of the sump pan. -
Page 28: Important Maintenance Tips
7.2 IMPORTANT MAINTENANCE TIPS Below are some additional tips in order to help with the general running of the vehicle to ensure reliability. o It is VITAL to check the chain tension after every run. The chain can sometimes slacken off during extensive running and will therefore require a small amount of tension to be applied by tightening the rear lower differential mounting nuts. -
Page 29: Adjusting The Chain Tension
7.3 ADJUSTING THE CHAIN TENSION 1. To adjust the chain the top differential bolts must be loosened on both sides. 2. Next loosen the large 24mm nuts on both sides. to increase or reduce the slack in the chain. 4. When tightening the bolts ensure the differential is pushed all the way forward 24mm nuts on both sides. -

7.5 CHANGING THE FRONT SPROCKET In order to change the front sprocket, first remove the M8 countersunk bolt inside the nut on the sprocket. (It is important to be careful when removing this bolt due to the thread containing Loctite; it is recommended to heat up the area slightly in order to make removal easier. -

Page 35: Charging Issues
8.2 CHARGING ISSUES The SR1 should be charging between 13.5-14.5 V when running on circuit. If you see it running below this, harging voltage in this section. Follow the below guide on how to diagnose the problem and deciding on the solution. When checking the car is charging, hold the RPM above 3000rpm. -
Page 36: Gearshift Issues
Is it shifting through all gears? Or just having trouble with one specific gear? If one specific gear this suggests it may be a mechanical issue and it is strongly advised to contact an authorised Radical engine shop for more advice on what to do. If you have carried out the first two steps and are still having issues shifting through all gears, take a look below for more help. -
