Check the two black wire connector just under the frontal end part of the brake lever..make sure they are in place. Its a blade slot type connector..can come off and not properly slight in. If that doesn't work..sprake some WD40 on the brake micro switch..its where these 2 wires are connected to. Good luck.

 

Hi Ah pek,

 

Tried this but still not working, any other solutions? Switch might be faulty?

Anything is possible like bad connection to broken contact pin in the connector to no supply coming to that wire due to wire corrossion. Use a voltmeter to test or supply and connectivity on the connector. The last thing u wanna fault is the float switch in the tank which is costly.

Hey does anyone knows why my spec I keeps gaining and losing power at speed 100+ with rpm around 6k? Its power keeps wavering, like you feel the power this second but the next second it starts to lose power and so on. All helps and advices are greatly appreciated!

Q: I've got a major problem that requires help with.

 

I am riding a Super Four Revo, which I purchased first hand in July 2008. Servicing has been regular, with the next servicing due at 53,000km (currently 51,300km).

 

Three days ago, while slowing down to almost idle (from office to home), I noted that my rpm was above 2 (marker), and there was this engine sound that normally, I would hear when I start my bike up in the mornings. I felt strange, as I've never had this sound.

 

Two days ago, when I started it, instead of starting at 2, it went straight to 1.5. Then it gradually dropped to 1. That continued on back home, and for the next day as well.

 

This morning, AYE (twds City) was jam-packed with vehicles. As such, speed was slow. As I clutched in, my bike stalled. (speed est. 15 km/h). Thought of detouring to the bike shop, but there is just too much work to do.

 

As I hit the CTE exit to Merchant Road, I filtered to the left, at a speed of about 80 km/h. I clutched in preparation to drop gears, and it bloody stalled again. The infuriating bit came as I left the tunnel to my office at Shenton Way. It stalled a further 7 times!

 

I'm at a loss now. Any ideas, bros and sisters?

Q: Have a problem with tachometer. Im riding a 10 year old spec 1 which i just brought last month. When i start my bike, the tachometer is goes from 0 to 4k and stays there, regardless of whether i rev the bike or not. The bike idles and moves just as well as before.

 

Not sure if its critical(guessing its not) but would like to know whats likely the problem and/or the cost of repair.

 

Thanks in advance. Have been searching the forums for this but cant find any similar posts. =x
