Sir, Please help me with following issue; I started my DR for the first time in 3 month. It started, but soon as I push back the quick throttle knob, it coughs and dies. Went through this couple of times, and the battery finally quits. I got a brand new battery but due to lack of time, I had to pick up the battery when it was only 85% charged. Dude at the counter said go ahead and ride it for couple of miles and it should be ok. I replaced the battery and it starts right away, but does the same thing. So kept the quick throttle knob out and rode it around 2k RPM for few miles. I thought maybe I should do the valve check, so I begin to do the valve check. After the adjustment, I put it all together and starts, and it does the same thing. Quick throttle knob out, it runs around 2k rpm, but soon as I push the knob back, it drops to under 1k and coughs a bit and dies. At this moment I check the plugs, and see one of the plug hole is very messy. It's oily around the plug. It seems there were some leaks around spark plug holes. So I changed the plug and go through it one more time. I ran it with quick throttle knob out and check the plug. It look like it was never fired. Mind you this was the brand new plug, but it seems it never fired. At this time, the brand new battery quits too. I jumped bike with the car and it starts right away. I check the plug again, and this time, it seemed it fired. So I thought, O.k. But the throttle knob issue is still there. The Knob out, runs. But the knob back in, it drops under 1k and dies. Is it the battery? or the rectifier? or something else? Anyone with any idea, please help this poor soul. Thank you for reading.
