When Harry Met Sally

I wanted to pass some bike stuff to Joe, the owner of my ex-Aprilia and arranged to meet up with him at 10.30 pm. What was supposed to be a teh tarik session between current and ex-owner became a lengthy support session that lasted till almost 3.00 am now.

It seemed that Joe was having a problem with the bike. He had problem starting the bike sometimes, and just faced the problem that the RPM would not go past 7,000 RPM. I had initially thought that Joe was not gunning the bike the way that 2-strokers needed to be coaxed with.

But once we exhanged bikes and I rode the Aprilia for quite a duration, I found that the bike was displaying symptons of water in its carburetor as per the following :

1) Won't start or run : If there is a large amount of water in your carburetor your engine will not run at all. Engines require a combustible substance in order to start up and fire; since water is not combustible, too much of it will completely prevent the motor from operating.

2) Rough Surging : The carburetor's job is to create the ideal fuel mix for your motor and supply your vehicle with the proper amount of fuel. If the carburetor is supplying your vehicle with watered-down fuel, or just has small droplets of water mixed in occasionally, your vehicle will be getting a mixture that does not burn effectively in the motor. It will cause the motor run badly, bog down when accelerating or surge as the vehicle alternately receives good fuel and fuel with water mixed in.

My diagnosis would be water in the carburetor, which reqires a mechanic to clean and flush the water out of the system.I would contact the mechanic tomorrow and appeal for him to assist in the carburetor job soonest possible.

However, despite this "teething issue" as Joe called it, the rest of the bike performed beautifully. The gear changes were swell, the brakes were great and the overall package warrant s 90% mark, let down by the erratic RPM.
 
I hope that we could settle this matter and have Joe having fun on his Aprilia again soon.

  1. Bos, nak jual ke Aprilia tu? Ni yang kamu iklan dulu kan? Minta tolong tanyakan tuan barunya berapa yang dia mahu untuk lepaskan moto tu. Saya ada 10 ribu kat tangan dah, tinggal cari motor seken yang istimewa aje.

  3. Bos, nak tanya sekali lagi samada moto Aprilia RS125 Tuono tu ada hati nak jual ke tidak? Kalau tidak, aku dah nak angkat sebuah jentera RS125 kat mamat Gombak yang jual RM8 ribu. Aku dah tanya kat mekanik- motor tu perlu dibaiki dalam taksiran sekitar RM5 ribu untuk jadi best nyer. Jadi saya nak tawarkan harga terakhir buat Aprilia kamu dalam harga RM12 ribu. Ikut hati, memang minat enjin RS125 yang dah dengan banyak cerita dan kalau dapat yang Tuono memang nampak lain dari yang lain. Kalau nak jual, tolong diberitahu sebelum 3 petang esok. Kalau tidak dengar sebarangan, aku akan beli jer motor RS125 kat mamat Gombak tu.

    1. Sorry, bro, I have already sold off the Aprilia so it's not my bike to sell. In fact, I was out riding with the current owner last week and I have casually asked if he was interested to let go the bike but he declined. So I don't think I would need to check with him on your request, bro. Note that the Rotax engine needs some TLC so be prepared to pamper and do up the bike from time to time.
