Carburator

I have been having this jerking problem since I get the bike. At around 7,000 - 8,000 RPM the the engine will jerk and when I eased off the throttle, it recover.

Since I was on leave (05/11/2008), I went to the bike shop to have it checked.

They cleaned the carburetor and re-install it but still jerking. They change the setting (not really sure how) but also no improvement. They changee the spark plug, no luck also. After almost 2 hour only, they found out that the big needle at the slide was not an original part.

They changed it and yeeesssssss........ it improved. They worked on it some more and at last it get better.

Now I can revved it until red line but still not perfect. I will bring it back to them later but as per now, the Daystar is a lot better than before. This morning I clocked 130km/h ant still not at red line.

The First 500km

I have done almost 500km on this bike. There are no obvious changes in the condition of the engine. There are no oil leaking, no increasing engine noise and no unwanted changes whatsoever.

I have checked the engine oil. Level is still at 'full' and the engine oil is still very clean. There is no overheating sign at the exhaust pipe or other part of the engine.

I have tried it up to 120km/h but regularly traveling at 100-110km/h. There is some lost of power at high RPM (around 7,000 RPM) but probably due to improper carburetor setting. I will have the mechanic check it up this weekend.

Overall, after 500km, I am pretty satisfied with this mini cruiser. I am looking forward to a long ride toward the end of the month (a day ride which could cover a distance of about 450km)

More than 11 litres

I refueled this morning with RON 97 fuel. To my surprise, it took a little over 11 liters to fill her up. She was not actually empty yet at that time.

If the bike really can go up to 46km per liter (as per claim by Daelim), that means I can cruise for at least 506km before the next fill up.

Wow..... that is a lot of distance.....

Engine Characteristic

Engine characteristic, well what do you expect!

125cc engine, 160kg of dry weight. Keep thing simple. The bike is for commuting only. No high speed, no super acceleration.

You need at least 4,000 RPM to launch. After that, the best gear change is after reaching 7,000 RPM. You can rev it more but pity the engine.

If you are doing tight turn, say U-turn or going into a 90 degree junction, you will be best at 2nd gear. Any higher, you won't be able to accelerate.

On the move, have to keep revving at 5,000 RPM or higher. You have to be patient. If you do, you can go far. If you don't, you will curse yourself.

For me, I enjoy it. Doing 90km/h on the open road........ relax..... no hurry ..... just ride.........

Bukit Mantin

On my way back, I decided to use old Mantin Road. Just to test this mini cruiser on hill climbing.

It was pretty bad jam on the way but it worthed. I was way up to the middle of the hilly road when I had to change to 4th gear and quickly 3rd gear. I was quite surprised. Even a 125cc kapcai which was much lighter than the Daystar, will have a hard time to climb the hill at 3rd gear.

I was crusing in 3rd gear as it climbed at around 70km/h up to the top of the hill without any problem.

So, the mini cruiser was quite a climber. When I reached home, I carefully listen to the engine again. No problem. Still pretty smooth.

First Ride to My Office

First task in the morning will be sending my son to school. He probably weight more than me. And the Daystar having a bit of a hard work to launch. A good 5000RPM was required for a smooth launch.

But after it started moving, everything is okey. I even tried it at a corner... not bad, not bad at all. At least better than my scooter.

On the highway, the real truth. This small capacity cruiser can only cruise. It was very comfortable at a speed around 90-100km/h. Faster than that, I feel like pushing it it too much. But at 100km/h, I have a feeling that it was actually a little slower than the meter reading. But at a slightly down hill section of the highway, it could reach 120km/h.

When I reach office, I listen to the engine. Everything seems okey. No unwanted sound or rattling of the valve or the tappet.

Pretty good for my first day ride to office!
