Vibrating Sound at the real wheel

I have not ride the GTR for quite a while. While preparing for my next ride, I accidently turn the rear wheel around on it double stand. Suddently there was whirling sound at certain speed.

The sound came from the location of the gear / auto-clutch. When I carefully examined it, it seems like there was also a leaking of gear oil al over the swing arm / drive belt casing.

It only appears/heard when I turn the wheel at certain speed. My goodness, back to the mechanic I supposed. But I was not free at the moment. I will have to wait for the next weekend to bring it to the mechanics.

I wonder how much will it cost this time..................

Cone Bearing Problem / Stiff handling

My handle was very stiff. It feel like an old bike. It lock the handle bar in the middle and manoeuvring at low speed was really a problem, especially in a traffic jam where you will need to zig-zag between cars and other vehicles. No choice but to get the mechanic to help.

To my surprise, he said the cone bearing (bottom portion) was damaged. The solution, change it with a new one.

So, I did. But, my god, it was expensive. Parts complete with installation was at RM150. After replacement, vroommmm....... the GTR is in good shape again.

Engine Died During High Speed Riding - continue

I was at NAZA agent yesterday. I mentioned about the problem that I had at high speed. According to the mechanic, they had already solve the problem.

There is a fuel pump to regulate the fuel. This fuel pump is too small to cater for proper fuel distribution during high speed riding. That is why I had the temporary engine problem.

The solution, by pass the fuel pump. According to the mechanic also, the original CPI model do not have fuel pump/fuel regulator.

Those owners of GTR out there, give it a try. I will do it soon.

Engine Died During Fast Riding

I was late to the office this morning. So, I push the GTR to the limit.

It was fine for the first 30 minutes but suddently.... brrrrrrrrrrrr....... lost power. I was travelling at about 110km/h when it happened. I released the throttle fully and pull it again. Just a little bit. Engine regain power but pooommmm.......... an explosion like and the exhaust. I continue cruising at lower speed. Luckily I reached my office.

I check out with a few friends, some says that may be due to insufficient petrol being fed to the carburator. And the 'boom' sound may be due to miss firing by the spark plug.

I lost my confident on this bike again. May be no more full throttle and surely no long distance riding.

GTR On The Road Again

I get back the GTR on Friday. Feel good with proper auto clutch again.

Today I was back on the highway with the GTR. It was okey but some how I feel that the RPM was a bit higher at a speed of 100km/h.

Starting was good. I get the acceleration like it used to. But the front wheel feel like vibrating a lot.

I pushed it until 115km/h. The vibration is killing my enjoyment on the scooter. May be I will need to go for a wheel balancing.

GTR Is Ready For Collection

NAZA agent called me last Tuesday. The said the GTR was ready for collection.

I really have no time to go and fetch the scooter. Probably I will go tomorrow (Saturday)

I cant wait to ride it again. It may be a lot of trouble, but you are riding it, I can assure you, not many can beet the marvelous feeling zooming around on this scooter.

I will update on the performance / result after the newly replaced auto clutch.

Lost of Power

It was Friday morning. After warming up, I just accelerated as usual. But to my surprised, no response at 4,ooo RPM. Add some more throttle, and at 7,000RPM only the GTR started moving.

I tried it on the highway, still cruising easily at 100-110km/h but as soon as I stopped, it took at least 5,000RPM just to start moving.

On my way back, I stopped at the NAZA agent. When they opened it up, there was oil in the clutch unit an on the drive belt.

I left it at the service centre.

On Wednesday the next week, I called. Problem not solved.

They have cleaned the transmission unit, but it still slipped. Now, they are liasing with NAZA head quarters to solve my GTR's problem. It's still under warranty though.
