what bike? by law, the mechanic need to quote you price first after first inspection to see roughly what need to change. If anything broken, count separately. I'd say around 200++.

ss2, nice... what's your mileage now?
If service change engine oil, clean carburator and air filter should be between 20-40, depends on how much is the engine oil.

Last time I full service an RGV (similar to SS2 as they are 2 stroke), cost me 200, with cleaning block piston and some parts changed because of wearout.

Painting a bike I have no experience.

Sounds like a nice SS2 you have there. Low mileage for an old bike.
My RGV almost hitting 30000 km soon. Time for full service like I mention above.

For your case, just change bike engine oil if just regular service, and do a full service at every 30000 km. If better, do a full service every 20000 km. Also, adding to my earlier reply, may also want to clean exhaust pipe. Easy job just take it off, and hammer knock until all carbon fall out from inside... If really bad case, need to use welding to potong exhaust liao. Normally, if you don't use cheap 2T, no need to potong exhaust.

To reduce smoke, look for cleaner burning 2T, with grade JASO FC, or better FD. I've manage to find Castrol Race 2T (Gold bottle) for around RM20 at Tesco. So far so good.

125Z is 2 stroke which is not good for long distance also not good for mother earth, that is why yamaha came out with 135LC to replace this version.

Over all both are good

White smoke or black smoke
Black means ur engine is having problem... burning black oil maybe
if white, u can't reduce smoke in 2 stroke bike.
If a 2 stroke has no white smoke means ur engine is not consuming 2 T oil

Oh, petronas 2T is slightly more expensive compared to other brands of the same grade.
It has 5 grades, if not mistaken, from no label, 1000, 2000, 3000, 4000 and 5000... with the last being fully synthetic and most expensive. Last I remember about RM40 a liter. And it's hard to find. Not all petronas station carry it. The next best thing is BP fully synthetic. For SS2, need not go this far lah, just sharing what I know... haha

Some old skool bikes forums recommend buying marine engine 2T, like those graded API-3TCW (W for water cooled). These marine 2T burns almost smokeless and leave little to no residue inside engine chamber. I myself is not a believer in this one, so I'm sticking with JASO-FC/FD. Btw, the marine 2T goes by the gallon, and reasonably cheaper at about RM30-60...

As for your steering shaking, few questions:
1. Are you still using the original tyre from the old spoke rims with the tube? Maybe the tube got folded inside causing unbalance, or the tyre already de-formed during the change. What tyre you using.
2. Have you checked tyre pressure? Can do at petrol station... make sure within normal range 30-32 psi.

yes you can use. not sure upgrade 2t will provide better runs. but ok la.
Check on ur new tyre. Is the tyre lumpy? normally is the tyre problem. as ur rim is new

lennz is right, you can just mix in the synthetic 2T to the mineral that you're already using.
Though I would recommend that you use until the 2T almost finish, then top up with the new one.
That BHP FB shouldn't be synthetic, if I'm not mistaken, but good enough for daily ride. You should notice the reduced white smoke. Given my experience with Shell FB 2T, the smoke is still quite noticeable.

Let me know how this new 2T turns out. Hope the additional 2ringgit is worth it.

As for your steering problem, there can be many possibilities. Suggest you bring back to the mechanic for check.

Added on May 18, 2010, 9:00 pmOh, I used to ride my friends SS. It goes up to 130kmh no sweat. That was many years ago. I was riding my Yamaha sports since then.

not new rim eh?

Rim brands not sure la. a lot frens bought racing boy rims..
anyway i am still using still rims.
y coz my area has lots of pothholes. Sport rims is no no around my area.
When my rim bengkok i can tune it back again.hehehe

want buy scooter, target below rm1500

Not sure how much that rim.
Btw, ubuntu, how's your bike now?

advice is to change whole set. better n safer.
ubuntu. do a test on ur rims n tyre.
double stand ur bike so the front wheel will raise.
then use ur finger or a stick to merely touch the side of rim
spin the wheel to see if the gap between ur finger or stick and rim changes.
If it changes ur rim is bengkok
if not change, Then try check with ur tyre.

ubuntu: thanks for the update, and i'm glad to hear that.
At least this confirms your 2T pump no problem, unlike my yamaha...

One of the reason I think, because when you top up the new 2T, there is still some of it along the 2T pipe to the pump... simple calculation would estimate ~50ml of it.

To burn off this amount of 2T needs ~10-15liters of petrol, roughly about 3 full tank... correct ah?

wow! sounds like a good deal... let me check out caltex tomorrow.
Btw, have your engine rebore before? If you wanna know how to adjust 2T, let me know.

hey i just noticed that when i use ron 97, my moto got better pickup, yay problem solved!!!
