My total garbage low quality ModernAss Dominar has now developed a new problem as the odometer passed the 10,000km mark.

Anytime I pull the throttle more than half & when the tacho passes 5000rpm, it starts to backfire & fart its brains out. I lost half my engine power.

That, and the fork seal has started to leak.... AGAIN.

No choice but limp back to ModernAss service center to claim warranty FOR THE THIRD TIME.

Dominar quality sucks cock.

just to chip in here.

clean the maf sensor insiode the air filter box. i diagnosed it something wrong with the maf voltage thru obd.

happen to my friend's dominar d400. this is due to air-fuel mixture backflow during throttle closure, thus contaminate the sensor. the sensor is bosch sensor.

just buy throttle body cleaner from mr diy will do.

ecu need to read the amount of air coming in, the contaminated sensor give erratic reading thus the problem.

Ye thats me and that black NS is mine :rofl:

I havent started stocking up on windshields, most windshield for the NS are installed over the stock "windshield", which i find rather filmsy. Theres this guy, windbro selling the bracket, its sturdy, but offers very little in terms of angle adjustment and looks pretty cumbersome. The bar you were mentioning is indeed usefull, but can get messy and clutter things up alot, i find that the easiest way to mount stuff is to move over to fatbar or just regular 22mm bar with a riser adapter. Looks alot neater too and provides a more comfortable riding position.
Also to add, we discovered multiple v1 and v2 user having this problem which leads back to water seeping into their tank. Early signs are rust spotted along the lips opening under the tank lid. The MAF sensor would definite go haywire when your fuel mix is contaminated with water. Light cases gives occasional stutter, most user reports problem going away after refuelling couple of times. In a severe case, the bike wouldnt even idle and was vibrating harder than an excavator when throttle forcefully opened to keep engine running and the exhaust smells aweful. A full tank flush was needed and the issue went away. Do check if you happen to have this, if you do, i suggest finding an o-ring the size of your rubber flange on the lid seal and place it under the seal to further reinforce sealing.
Yep we open daily for now. See you on sunday :smile:
