Mine is abt there too. FC is around 22K/litre (estimated)

[lutein]

[Q]1. There are way many models,

1(a) PB1 - Steel Headers, larger fuel tank, similiar engine spec as VerS/R.

1(b) VerS/R - As above.

1© Spec1 - Vtec engages at ard 6.5rpm?

1(d) Spec2 - Vtec engages later as Spec1?

 

Spec 1 Vtec opens at 7.0K rpm

[MUSHA]

Can anyone advise how much can a S4 Spec 1 with COE expiring May 2011 sell for?

Can anyone advise how much can a S4 Spec 1 with COE expiring May 2011 sell for?

 

IMHO..its kind of difficult to gauge its value just by COE alone. Have to consider the condition and current status and previous owner ability to have it well maintain. But as a reference..can always have a base COE price starting at $3k...again, IMHO. I know of a place having 3 very good rebuild PB1 selling at $5k above.

May be your side stand is not probably setup..the stand safety switch may be enaged. See if the switch is faulty.

hey guys, if there's a white smoke aft 7rpm wats wrong wif it? Went to shop n check n they say nid to replace 2 of e piston, shld i change e piston or only e ring? It only appear when rpm reaches 7 or 8...when start everythng normal...n if i were to change e piston, hw much would 1 cost, guys help me, ride s4v1 thankx.

[arsonist]

sometimes when i change gear up to gear 2, suddenly it will kick back in to neutral (making it seem that i am revving unnecessarily), what does this mean? time to change the clutch plates is it?

The emch is right..it's your piston oil ring and soon to follow will be your piston compression ring. I believe all four set must change not for just one ring set...not cheap!

 

Why would you want to change piston?..unless you are feeling rich. Cost?..all I know is that it freaking expensive and when you change, you ahve to change all 4. Change one?..can but I don't recommend. Anyway..labor taking and dismantling your block is already VERY costly.

Try readjusting your lower end side clutch cable tension and fine tune for proper biting point at the upper end. Make sure the level adjusting screw stalk is all the way in first. Otherwise, you nay want to replace your clutch cable..could be already stretch as "what you squeeze is not what you get"..thus improper engagement when you change gears.

needs assistance pls =/ ..how do i check if my tire is out of alignment..does goin freehand helps?

Not sure what your question really is..out of alignment with reference to what. If you are talking about back wheel asa whole and not alignemnt with the bike horizontally to the from frame..I understand. If this is what you meant..you have to losen the back axle nut and adjust with the chain tension adjuster. If wheel out..sprocket also out.

 

This can really be accurately done only if you ahve a main double stand for your bike..so that the back wheels float. Take your aim from the wheel center and oso double check the chain tension adjuster markers (should be same on both side of the swing arm) for same marker reading..or close by.

its after gear 2 engaged then it will go down to neutral on its own.. doesnt happen to other gears just from 2 to neutral sometimes especially if open throttle big big then more likely to happen.

 

if changing clutch plates, any other thing to change as well? gaskets etc? mite be going down FJT to get the parts.
