Now I know why Bajaj set the fuel light to come on that early with 2+ litres of fuel still in the tank. The internal tank baffles (if any) aren't very good.

Hit fuel cut midway in a higher speed turn and fairly steep lean angles With about 2L still in the tank. By right it shouldn't happen, since centrifugal forces should still have kept the fuel at the bottom of the tank regardless of the lean angles.

Maybe I just didn't go fast enough..... biggrin.gif

one major thing our friend got wrong, is the engine, v1 is single cam, v2(ug) is twin cam and produces approx 5bhp more than the v1. That said, personally i still prefer riding the v1, it vibrate ALOT less, and makes half the noise v2 does. Torque down low rpm feels more pronounced and more engaging that the linear v2 power curve.
*
For all intents and purposes. I also prefer the powerband of the V1. That was one of the reason I bought a late year V1 used instead of a new V2 (then just a month or 2 before launch)

On paper the V2's higher hp looks tempting, but it isn't until you realise max torque is also 500rpm higher (torque is same between V1 and V2). Higher rpm is fine with multi cylinder engines, but on a thumper, all it means even more vibrations to get to max torque. The V1 will be the more responsive motor for in town use where most of the riding will be between 5-6k rpm. In retrospect, it was exactly that I had expected when I chose the V1 instead of waiting for the V2... An unintuitive action from a potential buyer.

That said, the V2 does come with a lot of improvements over the V1 like brakes, suspension and other componentry.

I had a similar experience with my car also. I had a 1.9L (bored out and high comp pistons) SOHC satria with loads of low end torque which I do a bit of touge, hill climbs and short tracks with. Switched to the twin cam head and absolutely hatred it. Eventually put another SOHC head back on. The DOHC had 30+ hp more but moved the powerband some 1500rpm up causing a very weak bottom end.

Ran my tank dry till it sputters today.

Managed to squeeze in 11.5L of fuel. So whatever balance 1.5L of fuel left in the tank is just to allow you to sputter to a gas station....

Maybe the tank is smaller than the advertised 13L or there is an issue with the height of the fuel pickup.

well, the majority of the average consumers are pretty likely to be just brochure warriors, just like how people gets super hyped for the 50hp zx25r. It prolly take quite abit of experience with different type of bikes/vehicle in general to truly understand how powerband works, how torque correlate with hp, cylinder count/cam variant/boosts/gearing/compression/management/tunes and such affects the actual driving/riding experience over a spec sheet.

Or maybe the engineers would claim it to be "safety features" to protect your fuel pump laugh.gif

But yeah, most bikes has the pump installed towards the south of the tank, the lowest rear part of the tank as the fuel would stay there when bike is in motion. In all bajaj bike's, its usually at the center which is pretty odd if you ask me.

So god forbid you need to tackle an incline on low fuel. Hahahaha. Combination of forward movement and uphill incline means you'd never make it up.

now imagine you have 1 litre of fuel left, then petrol station is 50 meters ahead, but 20% incline. You shall experience the true definition of "so near yet so far". icon_question.gif

Haha...well this explains why the fuel light comes on with nearly 2.5L of fuel left. Bajaj knows you ain't making up that hill.

I carry a siphon tube with my bike... In order to help other riders that has run out...but looks like I might need it more..hahahahaha

I get range anxiety on my bi-montly trips back to ipoh. If I whack it, fuel light starts blinking before tapah. I suppose the range anxiety is well founded.....you don't want to run low going up the hills at tapah. Puts weight on the old bike saying. Fill up when you can, not when you need it.

Dominar still ok la, imagine 12L tank on a literbike like me, that's what you call true range anxiety haha. For me simple, fuel light comes on, just search for a fuel station, don't push your luck.

I can relate, imagine the anxiety doing top speed runs on zx10, no fuel gauge laugh.gif

When indicator turns on, i get rekt by 250cc bois

Your fuel efficiency must be horrible considering the weight of your balls required to do top speed run long enough that fuel consumption is your worry.

well when theres no fuel gauge on your litre bike, and you've tuned the hell outta it, and the low fuel indicator lights up while pulling 280+, despite knowing you can still go on for 30-50ish km, it definitely isnt fun sad.gif

Hi Vi Merkz,

My bike now at 20000km ,
1. My chain aren't working correctly and bouncing around when turning
2. Do I need to change air filter cuz I haven't change it since i got my bike in Sep 2019.
Might want to drop by your shop to change these few things.

Hello

1. That sounds about right, the factory chain(in fact most o-ring 520 in general), would hold up to 15-25k km, might be time to get the chain/sprocket set replaced. X-ring set would last longer, it cost more, but cheaper in terms of price-per-km.

2. We generally recommend a major service every 20-25k, considering all the below shares similar lifespan, you save in term of labor doing them at fixed 20-25k intervals instead of changing 1 by 1, items to be replaced on top of a general checks would be
- air filter
- fuel filter
- plugs
- coolant
- valve clearance

Modenas Dominar 250 is good spec and reasonable price. Since many user have issue.
Worry how the engine and wiring lasting.

So far just one very bad thing is the meter don't have gear position indicator.

Ima first gen D400 ~ you'll get used to it , gear position indicators are just a fancy thing we don't actually need.

tbh, just get the d400, has lots of value proposition on it, despite the fact you'll have to get a b full license, its all well worth it. In my personal opinion, the D250 is sort of like a lazily dished out model to shove in between the pulsar 200 and d400.

Again, if you're really keen on the d250, gear indicator isnt much of an issue as you can just replace the gear sensor with a D400 sensor and wire up a external gear indicator

nice write up! If im not wrong your batch wasnt fully local CKD, like the kawa by modenas, engine still comes as a whole unit, while the rest of them are assembled here. Earlier batches are less likely to be lemonades. That said, your bike still lookin great the last time we had the major.

PS : your clutch plates are in stock, and you left a bottle of coolant here

Havent tried D400 but D250 felt pretty heavy and under powered.

Is D400 better in terms of power delivery?

Yeah. Test rid one month ago. Feels like d250 is an afterthought.
D250 feels sluggish for city ride.
The ns200 feels more "kena" in its acceleration and handling. It just feels more right.
Harga pun more kena compared to the d250.
D400 rides much better imo.

I don't know how to explain technically, but the d250 throttle response seems laggier/weaker compared to d400. Make the d250 unsurprisingly less agile compared to d400. I guess he dominar body/chassis is just too heavy for lesser displacement, despite the smaller wheels.

That's just ride around town though. Haven't tried highway ride.
