AMG 13

hello guys i'm new here in Xbhp.com and as an early warning .. i dono much abt bikes other than the riding part and i'm sure that i'll learn much from the many experts on this website.

i'm interested in buying a Yamaha RX 100 . read many posts on many sites . all d ppl agree that it is a true legend .

so i went abt searching for this bike in Hubli , Karnataka (d place where i live)
finally found a used bikes dealer who's selling 1 ... the bike looks in pretty good condition .. didnt get a chance to ride it n all but it looked quite good
.. he has put on a three spoke silver alloy rims insted of the stock rims but thtats abt it .. i ask the price and wht do i hear ???? 28K????? i guess thats d reason no 1 bought that beauty ..

so toda i'm gonna take a mechanic and check it out thoroughly ..

also this is the first 2-wheeler dealing in my family so even dad knows nothin abt it and we dont know any trusted mechanic . dad fears that the mech and the dealer will both cheat us of our money and make us pay for a piece of crap .... but i convinced him to give it a try ..

so this is wht i wanna ask : 28k - is it worth it ? cos i've heard online tht ppl get RX100's for 10k-15k ... otherwise wht would be the best price ? and wht do i've to watch out for so tht we dont get cheated by the mech and d dealer ???

all help is well appreciated...thank you

Sunny

@AMG_13 - Welcome to the forum. Pls take sometime to go through forum rules & do post an intro about yourself.

First & foremost thing you forgot to post is which year of make this is & how many number of ownership is registered on the RC book. Are the papers clean?

I'm assuming you bought the bike just by what you heard from people through word of mouth. Correct me otherwise.

First, I don't know what's the condition of the motorcycle. A rotten RX can be bought anywhere from 5K to 8K & a running condition vehicle from 8/9K to 15-17K.

Warning - If you've made up your mind to buy RX, then pls don't read further

- The most difficult part of RX to obtain is the cylinder. Check if your cylinder is in stock or sleeved. If its sleeved its worth only about few hundred rupees
- Next, check for electricals & loose switches & the condition of the battery. If its 6V, then you may need to know that 6V is completely outdated atleast a decade & half ago. Check the conditions of ignition coil, rectifier & flasher (basically all electricals)
- Does the motorcycle run on oil pump or on premix? If on premix, then the oil pump has gone kaput. You may or may not opt to replace this one.
- Since the wheel rims are changes, is the motorcycle in stock? Means, there's a possibility of rear swing arm being changed.
- Is the motorcycle running on stock or after market carbs?
- What's the condition of the tires & size? Stock is 2.50 X 18 (front) & 2.75 X 18 (rear)
- Is there a disc brakes in the front?
- What's the condition of clutch & gear shafts? You may need to open up & check this one.
- What's the condition on the front forks & cone set? and the front & rear suspensions?
- There're several threads running on how to obtain parts for RX & there's even one running on how to file up a case with Yamaha. So be prepared to spends the days on waiting parts, rebuild projects.
- Last but not the least, be prepared to shell out a good money upfront for the "legend" OR in the form of FORD (Fix Or Repair Daily). Alternatively, buy a good 4 stroke engine that has loads of power than the "legend" for a trouble free rides in the forth coming years.

Whatever you choose, best of luck.

I know you're a newbie, take sometime, go through this forum & search for the pictures of the parts that I'm talking about.

Hey buddy,

why don't you put some detailed snaps of the machine ?? it ll help you to get a closer look to what you want as well as to the experts here to suggest you better options (i.e. get a RX100 in 8-9k and get it restored to your requirements) it will cause less damages to your (or your dad's) pockets.

check for slipped cylinder/head & spark plug studds. (look for oil leaks)
gear box and clutch condition (make a test run rev through the gears, you will come to know)
brakes especially with the after market alloys
top end/bottom end bearings (listen for engine sounds), cranks are difficult to get. in case if it needs a crank overhaul never go for a bigger crank pin local job.
bent chasis & cone-ball condition (bike pulling to side at low speeds, look if front & rear tyre standing in a line )

good luck

@AMG_13 - Pls avoid SMS language in the forum such as "sum pics for u too 2 look at", "let u know all d details toda". Pls take sometime to go through the forum rules as SMS language is prohibited.

To answer your question
Before opening, first check is the smoothness of gears shifts; it could be due to wear & tear on clutch plates & friction plates. So check them first & replace if necessary. If you still don't feel the smoothness (note that you'll see an improvement after the replacements, so do not take that for smoothness), then the shaft would've been bent. Such things are rare to find, but if you find, its very expensive affair to replace them & to find them too.

Little difficult unless you ride the motorcycle for 50 odd Kms. If the front forks are bent, you'll frequently find the oil seals to be breaking & oil pouring out; if cone set is worn out, you cannot keep the motorcycle steady, it usually tilts off to one side even if you position the handle bar to the other side very slightly.

PS - I hope this is your first motorcycle in the family. Why don't you guys go & get a new motorcycle? Experience the taste of new one, learn the nitty gritty stuff of owning one, visit the A.S.S & know what they do & then think of getting a used one? For now, try getting a FZ16 & trust me, its as powerful as RX or if you like the straight sitting posture, go for an TBTS/C5/C3 or ZMR that're very comfortable. If you post a question for a new motorcycle, I'm sure you'll be flooded with good choices.
