Been along time since I have touched this engine and thought it time to do some more but I'm stuck, I have circled 3 bits I'm stuck on can one of you on here advise me on what bolts in these hole or hopefully nothing does because I have nothing that on my engine shelf that would look to fit 🤔🤔🤔

You guessed right Martin! From the best photo I could find 1 and 2 are blanks (why bother Mr Yamaha??) and 3 is for the kickstart stopper if you have one fitted wink

Well done Martin - excellent work!

After-market indicators tend to have smaller wattage bulbs fitted. What are in yours 10W?

If so, you need a flasher unit to match - or put in higher wattage bulbs - or put resistors into the circuit wink

Hi Brian it doesn't say what wattage they are just says 12leds bulbs and says low power consumption.
Think I'll give the resistors ago see if that sorts it👍👍👍

Looks nice

Easy to adjust the idler screw, just turn it a bit to increase tick over.
