i haven't do. lol. just checking the price only. 350 is a really good price man.

When touring, its usually the rider that give way first before the bike itself.

When to do valve clearance?

 

Two options - one is just leave it if the engine sounds right. Can't guarantee max efficiency over a long period of time. Waiting for the valves to become noisy (obviously out of tolerance) may have risk of engine damage or running with lower than normal efficiency. If engine seems to lose fuel economy over a period of time this may be one of the causes.

 

Second is to imitate the manufacturer's warranty service schedule and do checks on the valves to keep them within spec, and this will keep the engine running at optimal efficiency. I'm currently creating such a "warranty service" procedure for myself, checking valves/timing chain every 10k km or so.

 

My Phantom was running on the same timing chain & tensioner for over 60,000kms and valve clearances more or less, never. Ran much better after doing VC. Was cheap and fast at Planet.

 

Hmm.. For u bro, hw much u did vc for u phantom at planet?.

s4 should be more ex. more valves, more cyclinder.

 

phantom only 1 cyclinder nia.

February 2011 - March 2012 = Phantom TA 200

March 2012 - August 2013 = Suzuki Impulse 400

Present = BMW (Bus, MRT, Walk)

Correct me if I'm wrong, but I think Vtec will jack up the cost too? Cuz need to remove camshaft to insert locking pin for the the Vtec valves. At least that's what I remembered reading for the VFR800 in Bike mag. That's just for checking though. If need to adjust, then won't make a diff anyway I figure.

JIALAT. means must change timing chain?? like that i pok liao =(

 

Ur XR125L have no timing chain. It's a CG125 engine. Push rod design. This one is even easier to do valve clearance.

 

-Cool down engine overnite.

-make sure crank is at tdc. This one is tricky. U need to know what is goining on and what to look for

-Take off tank.

-open head cover.

-loosen tappet locknut.

-tighten tappet until pushrod cannot rotate in it's position. please don't use bill strength. gentle gradual strength will do

-loosen tappet gradually until pushrod can rotate freely. Lock tappet locking nut. double comfirm push rod can turn freely.

-Assemble everything back and test engine.

 

It should have a faint sound of tappet sound. Too quiet is danagerous.

 

OR, send in to any bike shop. All can do pushrod engine valve clearance one. This one can actually do without feeler gauge and still can get accurate clearance. Unlilke OHC chain drive. they need feeler guage. DOHC, shims and bucket design is worst. they need micrometer and have to take out the OHC.

ooo. like that not so bad. is it a must to cool the engine overnight? means i must leave the bike at the bike shop overnight? i don't think i'm competent enough to do valve clearance myself

It's better to cool overnight as the metal is fully contracted. That is the most accurate physical state when doing valve clearance.

 

No worries. Not everyone do their own valve clearance themselve. When in doubt, do send into bike shop. get a trusted bike shop to do.

      TW200 Brothers!
       
      Need help on this. I just bought a 11 years old TW200. I went to Ah Chong (Planet Motorcycle in Ubi) but he mentioned parts are hard to find for TW200 so might not be able to help much.
       
      Is there any workshops or mechanics that I can go for servicing and see what needs replacement?
       
      Thank you in advance!

      Selling my Silver Surfer Phantom TA200 Custom 4 version! Served me well for the past 5.5 years and it's looking for a new owner.
       
      External condition is 9.5/10. See the photos for yourself to believe! Bike is accident free. Regularly waxed.

      Comes with unique 2-digit number plate worth at least $1000 to bid for!
       
      Accessories worth more than $600 are yours with the bike!

      The only defect is the engine, which needs an overhaul. Planet Motor quoted me $500 for it -- Do factor this into the cost of owning this bike.

      Bros, I browsed through a few old threads 2010 and earlier about bike workshops that open on Sundays, but would like to know if anyone knows of any updated list (it's 2016 already!) of bike workshops that open on Sundays?
       
      Not just Sundays but ones that open till late (beyond 9pm) on weekdays as well.
       
      Every help will be appreciated, cos I'm looking to replace my chain+sprocket asap.
