Hi All,

I was wondering if anyone can point me in the right direction. I have a Pulse Adrenaline 125, last night I changed the speedo drive.

Afterwards when I tried to start the bike its doesn't start. The strange think is, when I put the bike on a uphill angle it started, downhill angle it doesn't. When it does start, as soon as pull off it stops. I was suspecting maybe it was a vacuum issue, but when it does start it will stay on. I have had it running for 5 minutes, but as soon as I set off it cuts out. I have checked for spark on a uphill angle and there is one single spark when I first turn the engine over, but its doesn't repeat. A friend said this is normal, can anyone confirm this?

I did drain the front brake fluid when putting the front break disk back on, do you think this would have anything to do with it? I'm thinking is there possible a sensor inside the brake fluid reservoir.

I did have a slight "mini-drop" when I was putting the front wheel back on, The toolbox the bike was resting on collapsed, the bike didn't fall on the floor but it dropped rapidly for about a foot, no visible damage was done and I really didn't think much of it. I have been suggested I may have disturbed something in the carb and need to dis-assemble, clean and check the floats, does this sound correct?

Can any suggest what steps I should be looking at in order to resolve this.

Few points.....

This bike doesn't have a side, so its not a faulty switch.

I have checked the fuel flow to the Carb and that seems fine.

The vacuum pipes all look OK
