Tips Membeli Motor Bekas

Saturday, December 3, 2011 4:45 AM

Tips Membeli Motor Bekas
Anda berminat untuk membeli motor bekas, usahakan untuk berhati-hati dan perhatikan motor itu sendiri. Karena tidak sedikit pula pembeli yang kecewa karena kesalahan mereka sendiri yang kurang berhati-hati memilih motor bekas tersebut. Langkah yang dapat anda lakukan adalah:



1. Cek harga pasaran.

Sebelum anda melakukan pencarian motor bekas yang akan anda beli, sebaiknya lakukan cek harga pasaran terlebih dahulu baik dari koran, majalah atau mungkin bisa juga dari situs-situs otomotif di internet.

2. Cek nomor rangka dan mesin motor.

Periksa nomor rangka dan mesin motor, lalu sesuaikan dengan nomor rangka serta nomor mesin yang tertera pada STNK maupun BPKB.

3. Cek kondisi fisik.

Periksa kondisi body, spion, baut, dan lain sebagainya, apakah terlihat banyak goresan, kondisi retak ataupun pecah. Usahakan juga akan lebih baik jika semua yang menempel pada motor adalah parts orisinil.

4. Cek kondisi oli.

Usahakan buka dan ukur oli yang ada di dalam mesin. Pastikan ukuran Oli tidak berlebihan, karena Oli yg berlebih akan membuat suara mesin menjadi lebih halus, sehingga dapat menyembunyikan suara asli motor yg mungkin berbunyi kasar atau berisik.

5. Cek speedometer.

Pastikan agar tidak ada retak atau adanya bekas pembongkaran. Lihat jumlah berapa km yang telah ditempuh oleh motor tersebut. Jika diatas 20.000 km maka dapat dipastikan akan banyak sekali komponen mesin yang akan segera anda diganti. Tentunya akan membutuhkan anggaran yang tidak sedikit.

6. Hidupkan mesin motor.

Coba hidupkan mesin motor tersebut, apakah bisa stationer atau langsam. Karena kondisi pada mesin yang tidak bermasalah dapat langsam pada putaran kurang lebih 1500 rpm. Serta pastikan juga bahwa tidak ada bunyi-bunyian yang kasar didalam mesin.

7. Cek perpindahan gigi.

Jalankan kendaraan dan perhatikan posisi perpindahan gigi apakah terasa sulit atau tidak. Apabila terasa sulit berarti menandakan kampas kopling motor tersebut akan segera habis. Satu lagi yang perlu diperhatikan juga adalah, jika terdengar suara mendesir pada saat motor berjalan. Kemungkinan besar gigi primer dari motor tersebut akan segera habis.

8. Cek rangka atau sasis motor.

Perhatikan kelurusan roda depan dan belakang, dan pastikan bahwa rangka atau sasis motor tersebut tidak ada kebengkokkan. Jalankan sekitar 40km/jam dan tekan rem sedikit mendadak untuk pastikan motor tidak sulit dikendalikan. Hal ini berguna untuk mendeteksi lurusnya sasis dan poros setang atau setir.

9. Cek kebocoran.

Usahakan anda dapat mencoba jalankan motor lebih lama, dan setelah motor dijalankan kurang lebih sekitar 500meter. Perhatikan apakah terlihat adanya oli yang bocor melalui sela-sela mesin. Atau adanya air radiator bocor bagi motor yang menggunakan radiator.

10. Cek kondisi kelistrikan.

Periksa juga kelistrikan dan lampu-lampu seperti lampu depan, lampu sein, lampu rem belakang, klakson, lampu speedometer, atau elektrik stater motor. Apabila semua berfungsi atau hidup, berarti tidak ada kerusakan pada komponen dan kondisi aki tidak ada permasalahan.

Semoga bermanfaat, dan jangan lupa sesuaikan harga yang ditawarkan oleh penjual dengan kondisi motor yang akan dijual tersebut. Karena setiap motor tentunya memiliki kelebihan dan kekurangan masing-masing…

Penyebab Kurangnya Tenaga Motor

4:42 AM

Bagi setiap pengendara motor, hal apa yang di inginkan selain melaju dijalan raya dengan tenaga mesin yang optimal, akan tetapi penyetelan komponen yang tidak tepat atau kurangnya perawatan membuat harapan tersebut tidak dapat terlaksana.
Kalau Anda termasuk salah satu orang yang merasakan masalah serupa, berikut beberapa bagian yang dapat diperiksa.

1. Saringan udara
Cobalah untuk membersihkan komponen yang berfungsi menyaring kotoran dan debu dari udara, sehingga memungkinkan udara bisa masuk lebih banyak keruang bakar, ini karena mungkin ada banyak kotoran yang menempel sehingga menghalangi asupan udara ke ruang bakar. Akan tetapi kalau anda merasa komponen ini sudah lama tidak diganti sebaiknya segera ganti dengan yang baru. Penggantian ini dilakukan paling tidak setiap 20-25 ribu kilometer atau bersihkan setiap service rutin bulanan.

2. Karburator
Didalam komponen inilah proses pengabutan (proses dimana bahan bakar bercampur dengan udara untuk pembakaran yang pada akhirnya proses tadi menghasilkan tenaga untuk menggerakkan sepeda motor berlangsung). Oleh karena itu, sama seperti saringan udara, kebersihan komponen ini juga patut di perhatikan. Service ringan rutin adalah salah satu cara menjaga kebersihan komponen ini.

3. Busi
Busi yang sudah “berumur” menjadi penyebab lain hilangnya tenaga motor karena percikan api yang dihasilkannya tidak konstan. Hal ini disebabkan karena sudah kotor dengan jelaga atau celah busi sudah tidak tepat. Sebagai langkah darurat anda bisa membersihkan busi tersebut dengn meniup dan menggosoknya dengan ampelas. Demikian pula untuk mengatur jarak antar elektroda.


4. Jarum Skep
Penyetelan komponen yang menjadi bagian dari karburator ini perlu dilakukan, karena tenaga mesin yang tidak optimal bisa juga disebabkan karena jarum skep yang terlampau tinggi. Kalau anda tidak dapat menyetel sendiri, sebaiknya bawa kebengkel untuk hasil yang lebih maksimal.

5. Knalpot atau muffler
Knalpot yang tersumbat oleh kotoran hasil pembuangan dari pembakaran juga menjadi penyebab tenaga motor menjadi melorot. Oleh karena itu lakukan perawatan pada bagian ini setiap 3 bulan atau 6 ribu kilometer agar kebersihannya dan performanya pun bisa tetap terjaga.Bagaimana cara membersihkan muffler: menurut Bro Panca, “dibakar dalemannya dengan cara tuang minyak tanah lalu dibakar”. Beda lagi penjelasan dari Bro Ernest , Dia bilang “kalau knalpot motor 4 tak tidak perlu di bersihin, karena kalau muffler 4 tak itu lebih kering dari muffler mesin 2 tak, kalau mau sich ganti glass full atau lem biru, kalau yang di baker itu untuk muffler mesin 2 tak".

Semoga bermanfaat Bro!

BMW Motorcycle Repair and Maintenance

5:39 AM


BMW motorcycle restoration, troubleshooting, repair, maintenance, service, tools, technical information, tips.

Here are more about 200 pages of BMW motorcycle trouble shooting, repairs, restoration and maintenance tips for older models. Learn to fix your BMW motorcycle from some of these pages. Specific questions that I have received by email about certain issues have been addressed in this format. This way I only have to write it once. I do not take phone calls.

I owned and operated "Duane's Shop" in San Francisco from 1968-1971and then received a BMW franchise and moved to Marin county. That shop was called "BMW of Marin" and employed 4 full time mechanics. It was the largest service facility for BMW motorcycles in the USA. My experience almost came to a screeching halt in 1975 when I sold my shop. I continued as a BMW dealer, until 1980, way out in the boondocks, on a hobby basis only, with Fort Bidwell Shop.

This site is not intended to be a complete or "ultimate" book on BMW. I only write on subjects that I know about, remember something, are not addressed on other tech sites, or are addressed in error. If a subject isn't covered here, that may be because it is well done on another tech site, or because I know nothing about it. You may find it on my links page.

All of these pages are incomplete. Check the date at the bottom to see the last update. An update may be major, or minor, but I am updating pages at least weekly.

Other repair methods may exist that may be better suited for your application. Read everything that you can find and then decide how to proceed. New technology and re-produced parts may change what I once knew.

Easy ways Caring for Motor!

5:33 AM



If the motor is started fussing, most annoying! especially for those who like going home on a motorcycle. Do not rush to blame your motor, it could be you who care about motorcycles. So there's no harm in treating motor peering following tips!

Check Oil Condition

Engine oil is a very important role to grease the engine components, such as the handlebar piston, piston, and piston rings, axles and noken crutches or handlebar as valve. If the presence of lubricating oil is blackish color or reduced flexibility lumasnya power, it should be replaced. Change oil regularly and use in accordance with manufacturer recommendations.

Check Condition Aki

Do not let water accu through maximum and minimum limits that could accelerate as a result of damage to cells accu. Add the battery in the morning.

Do not let the battery or batteries that have started to weaken, immediately replace it, it's not good if you are still forced to use it. If still forced both positive and negative poles will remove corrosion (white powder) that will spread to the main cables that connect the electrical current to the channel lights, dynamo, or other parts.

If indeed you have this motor, the electric current is delivered battery or batteries are not perfect will cause damage to the components of dynamos, switch contacts and light machine. One thing to note if the batteries are weak or unable in the starter and distarter, do not force pushing the motorcycle to turn it on because it will only damage gear.

Check the chain and Gir

Do not let the chain is too loose or too tight. Too loose can make a chain off of girnya, while too fast can result in broken chain. Check also the condition of gear, if it is a sharp change soon because otherwise the chain can suddenly end. Danger not, reply again suddenly sped off the chain?

Check cable and Busi Koil

Note the presence of the cable that connects the coil electric current to the spark plugs. Quick change cable apparently is old enough and a lot of visible cracks and hardening of the cable. Do not forget to note the presence of spark plug for spark plugs is vital for smooth running of a vehicle engine.

Note Hose Stations

Gas hose to the carburetor merupakanm also noteworthy components. Do not let the fuel hose condition occurs hardens or cracks, because the inside of the hose can be no inelastic and lead dust from the dirt washed into the carburetor hose. Will eventually happen blockage of gas supply from the tank to the carburetor so that disrupt combustion systems.

Heat Engines longest 2 Minutes

Heat the engine before the motor running, do not have to stay long enough for 1-2 minutes to the circulation of lubricating oil in the engine parts are moving. Do not be too long to heat because it will make tailpipe yellowed otherwise you would not want to waste gasoline khan?.

Check tire pressure

Do not be too hard and also not less because it can result in damaged motorcycle tires developed.

Always Use Original Spare part

Better a little expensive, but satisfied and durable than the use that is not original, but even cheaper but less durability.

Not so difficult is not, provided you are diligent in properly caring for a motor bike must have your favorite show senatiasa prime. (honda / rit)
