Royal Enfield Thunderbird Twinspark Clutch Switch Replacement

Royal Enfield Thunderbird Twinspark Clutch Switch Malfunction

Recently strange thing happened with my Royal Enfield Thunderbird Twinspark motorbike. Self Start button was not starting motorbike in neutral gear no matter how many times I press but the moment I apply Clutch Lever motorbike was starting well.

(Note: Self Start button was starting motorbike in Gear while applying Clutch Lever)

The question: Why motorbike is not starting in Neutral Gear when Self Start button is pressed without applying Clutch Lever?

Many mechanics, many questions and many answers in the air. Finally the actual reason was found by a dear friend having his own Royal Enfield service center. The problem was with Clutch Switch as it is worn/malfunction now and why not motorbike is now more than 3 years 6 months old. This is the first time Clutch Switch issue occurred. I have no complain.

Upon query knowledge was enhanced by dear friend by showing how Clutch Switch function and what went wrong?

Clutch Switch works well with the help of a bar (shown in the picture within red circle). The bar helps to make motorcycle start in neutral gear as well as in gear when Self Start button is pressed. If the bar is fully inside the Clutch Switch it helps to start motorcycle in Neutral Gear. And when the bar is fully out due to pressing of Clutch lever it helps motorcycle to start in Neutral as well as in Gear.

Now in my motorbike case Clutch Switch bar was neither fully inside the Clutch Switch nor it was fully out and was in the middle but when Clutch lever was pressed it helps bar to come out fully and start the motorcycle in Neutral or in Gear.

The bar due to in and out many times since 3 years 6 months is worn/malfunction now.

The solution?

A brand new Clutch Switch because one cannot replace the bar only. One has to replace Clutch Switch.

Replacement was done. Rs. 90/- Clutch Switch cost and Rs. 30 labor charges. Total Rs. 120/- paid.

I am happy now. Knowledge was enhanced by dear friend. Motorcycle is now starting well when self start button is pressed in neutral gear without applying Clutch Lever. Thank you friend – said I. And I hope I am able to make Royal Enfield motorbike riders explain in general words about Clutch Switch malfunction and replacement.
