frankly speaking, no time no drag really bike will become more and more less power leh.

 

and did u do valve clearance b4?

ok..some ppl were wondering abt the type of spark plugs ( known as S.P hereafter for laziness sake) to use on yr v4s??

 

some of u guys remember the horrible experience i had at a certain motordiam right?? remember i told u guys my bike backfired, sputters, chokes, wont rev properly thruout the rpm range and kept jerkin??

 

part of the cause was WRONG S.Ps used. and the S.Ps was????? DENSO!!! tha part number when i took out was wrong whereas the motordaim ppl claimed they use it on thier customer RVF. well..cant argue with facts as i had the Haynes RVF manual. and it states there the only part numbers of SPs that RVF can use.

 

lesson learnt. i stick to NGKs now.

 

forget about what IRIDIUM la.. rvf engine and carbs is very sensitive one. spark plug dun any old how change, if u even as put it back without screwin on tight enuff will give u problems too. stick to stock is best.

 

to me even changin to BOSCH 4 point IRIDUIM or Platinuim tip or whatever sparkies oso no use one...at least no significant difference to me. unless u have a aftermarket MSD (for cars) sparks generator to match, i advise u forget it. believe me, i tried on my car before and only difference it made was a hole in my pocket.

 

down here, the team believes Stock is Best.

Thanks bro, for your advice to forget iridium plugs which i thought of trying.

becos u seldom rev till 14500 k rpm thats why bike sound horrible.

the top part of ur piston think rust liao lah. hehehe, joking.

 

1st, 2nd, 3rd gear drag till 14500k rpm once in a while mah.

Don frighten me leh.haha.hear you say rust liao i scare.today saw your bike at SP,saw your bike fix with steel braided hose.is it good?i mean the braking effect.Is it more sensitive?Goodridge brand issit?how much you pay for it?thx

steel braided hose is good....it saves me alot of time already....

even better with ebc HH brake pads....

[Ken]

braking effect definitely better, much more better and faster respond

 

valve clearance is do every 20000km.

 

why ah, last time i heard is power will be deducted by a lot.

bike had to rev.

 

and last i heard is if didn't clear, valve will break and he seems to be very serious.

 

actually by doing proper maintainance to the bike is already good enough to acheive good power.

how u noe ur spark spoil then?

 

u got see the spark urself?

 

if no, the mech told u?

 

hehehe kanna chop liao?

 

when spark plug spoil, there's no way u cannot detect it, unless ur mind is wondering on something else.

waa...steady leh Ken! last days on RVF liao..still so active in the thread!

 

anyhoo....correction; there IS a way of telling if yr spark plugs are firing. its even listed in the Haynes i think or run a search on the 400greybike forum.

the way is to take out the suspected misfiring or non firing plug with the plug cable attached. Rest the spark plug metal part to the Engine's metal casing... (act as Grounding) and start crankin yr bike. if all work swell..u should hear a nasty sound as the bike fires up on 3 cylinders and u can see the xposed plug actaully sparking.

 

Warning: dun do this near open fuel tank or when there is combustible fumes around. DONT hold the plug metal part when u are cranking.

Failure to comply will result in damage to vehicle and/or serious injury to personel.

 

jialat liao,next time see hurricane must siam liao,after hearing what you say.haha.if not kenna makan by them again.And also don let them know that we are at a disadvantage,if not they sure yaya always want to chio us run if there is a girl riding pillon.

 

Nvr mind one..not scared not scared!! be Really Very Fierce! Either u EAT him in the corners or get a full set of 2 brothers or Yoshi exhaust (properly tuned of coz)

 

BTW...u said u ride 8 years liao ah?? walan eh! that means PGMs and RVFs were yr generation time that time wor...why didn tu get a PGM instead when u keep envying thier pickup? BTW ah u!! tong 8 years then upgrade 2A..u must love yr 2b bike alot.

always listen hard to ur engine and soon when nextt ime ur engine got a flu only u will noe, but u might become paranoid like cheh san and me last time. hahahahahaha.

haha .. i was also at the same time trying to access myself to see if i am over-reacting or being over-sensitive.. haha

 

actually, if mai hiam .. actually, my bike still not tt bad ..but somehow i kept thinking sth is wrong...maybe i gotten used to 400 cc liao .. so now craving for higher cc???

i went to knt to tune on the first time.. clifford stood there v long to hear my engine .. then he said sth is wrong but couldn't find the prob .. until he pulled out one of the plug and realised it has fused or rather coated totally black liao ..such tt tt chamber wasn't combusting at all

Ya,i agree with you that rvf handling is good compare to other sport bikes,which i cannot deny.But i donno why sometime squesse between cars also will kiss other car mirror with my mirror,which i seldom encounter this during my eight years of riding of 2B sportbike.haha.We cannot ride like all those johorians on their cup kia,manouve very easily between traffic jams just like a snake.

diff la .. 2b bike's mirror dun protrude as much as rvf mah .. anyway, our bike size width is bigger also liao .. so cannot compare this way .. jus be careful can liao

 

these days, sometimes i rev till 10k rpm when i hit the expressway.. shiok man .. the pull really comes in at tt time ... can get high and addictive

but haven't rev till14.5k liek what ken say .. i scared my engine chui

this is the normal method .. i was actually looking for another easier and less hassle method to check .. very truoblsome to take out fairings to see the plug leh

[vroomvroom]

i got a qn to ask abt v4 engine ..

can someone accurately tell me .. what do u mean by v4 can pull your bike out of a bend or corner? last time i ride kips cub corner also can pull myself out of corner... dun really feel or know what is this 'pull' by the v4 engine even though i got feel the torque even when i am at a bend or corner and i throttle... other bikes without v4 also can do tt right?

[Ken]

something i quoted out from the hands on oil change thread.

 

very informative.

 

Just to share some information on engine oil

 

Oils can vary in viscosity (thickness) at a given temperature. Oils falling into different viscosity ranges are given a number by the Society of Automotive Engineers (SAE). The numbers start at 0 and go up to 60 - the higher the number, the thicker the oil. However, you may have noticed that some numbers (between 0 and 25) are followed by the letter "W". The "W" stands for winter and a "W" grade oil flows better at low temperatures. Non-"W" grade oils are summer oils designed to be thicker at higher temperatures (100°C) and keep moving surfaces apart.

This designation system originates in the early 1900s in the USA, where a thin oil was needed in winter so that it would flow easily. A non-"W" grade was needed in summer because the hotter conditions required a thicker oil to provide engine protection. Oils had to be changed at least twice a year - once for winter and once for summer.

 

Today, with the use of special additives, we can make an oil that will match both the thickness of a "W" grade in cold conditions and a non-"W" grade in hot conditions. We call this oil a Multigrade and give it two viscosity numbers such as SAE 15W-40 or SAE 20W-50. The "W" number describes how the oil flows at low temperatures and the non-"W" number describes how thick it is at higher temperatures. In this case, the second oil would generally be thicker than the first in both cold conditions and in hot conditions (100°C) because both of the numbers are larger.

The benefit of having this thinner oil is that it will flow more quickly from your sump to your engine parts when you start the car. This will enable quicker protection and reduce friction and wear on start-up.

Generally, your choice of oil would be provided by the vehicle manufacturer. The most common multigrades would be SAE 5W-30, SAE 10W-30, SAE 15W-40 and SAE 20W-50. The reason for using the lighter grades is that, because they are thinner, they provide less resistance to the moving parts and so provide increased horsepower and better fuel economy. Also, a well designed oil of low viscosity can provide protection of metal surfaces in most conditions. Heavy oils such as SAE 20W-50 can reduce both fuel economy and horsepower and are usually recommended less for modern cars.

 

Generally, oils of lower viscosity will help to improve fuel economy because the moving parts in an engine will not have to overcome the internal resistance of a thicker oil. This would mean that more energy could be used to drive the wheels or, alternatively, less fuel would be required to get to your destination. This is only part of the story, because although a thinner oil will offer less resistance to movement of the engine parts, you need to have an oil that will be thick enough or have the additives to prevent the moving metal surfaces from touching when the oil gets hot.

 

3000km is a good mark to get oil change as this is when all the acidic sludge forms in the oil and can proof to be very corrosive

[Ken]

maybe means pull can be better.

 

anyway, this pull thing is can feel it when like corner at 3rd gear rpm over 8k? then can feel the difference.

 

u go in a corner in that rpm or higher than that then u can feel the pull is better.

 

should be like that, although i never try that b4.

[vroomvroom]

i now using 15w 50 .. perhaps can switch to 10w 40 range for better fuel economy and better horsepower... seems the only bad point is a more frequent oil change .. but if can increase fuel consumption and horsepower..why not

i dun feel any diff when i use a 10w-30 or a 15w-50 actually

so i use a 15w-50 silkecone Ride 4T all the way which is cheap.Its a semi-sny oil and cost me only $5.50 per bottle

[Lao_yang]

HELP HELP.bike cannot start liao....... eve the crank sound also dun hv liao...how?wat happened?

 

And rem there is another way to start the bike without pushing.....push like hell liao still cannot start.....rem it something like push bk 3 time den forget the rest liao.

 

DAMN FU*KING SIAN!!!!!!!!

No cash ma,so never upgrade lor.only can envy bikes.haha.Ya,you are rite,pgm and rvf came out at my time.and i remember rvf is very expensive.ard 18.5k in the newspapers.this price at that time can nearly buy a r1 liao if top up a little more ard 3k.pgm consume alot of 2t leh,and parts definately wear out faster.Actually i did make a comparision between pgm4 and rvf b4 i commited into buying my rvf.It can be considered my dream bike many years ago.Both are very good bikes actually and got market value lor.There is another good bike which is rs250.heard from my mech that this bike is better than pgm4 in speed and pickup becoz of it carb size.However,this bike is not very popular and its market value is not so high.Hope all rvfdians don find me bored talking about all these.

even better with ebc HH brake pads....

ebc HH brake pad is very expensive.haha.Enquire abt this price.Ard 70+ bucks.Me using Gold HH brake pad now lor.So how much to fix a steel braided hose front and rear?estimated?

this kind of feeling is very common.so don feel bad about it.same for me,thats why always thinking how to make the bike more powerful.thats quite bad ya,cos pocket burn hole liao.kekeke

ya lor,rev till 14.5k scare engine chui also.rev till 10k try b4 liao.fly on the expressway at 180-200km/h.luckily not TP,if not sure die.remember i got one time chasing a ST11.very power also this bike although it is bulky with many stupid boxes,thought the fellow cannot run,but i was wrong.

[bikemania]

Thanks guys for yr concern!!! I am back at hm nw and TP had caught the taxi driver already. This time i going to sue him until he jialat jialat. he really make me n my dear bike suffer a lot. I can only use 1 hand to type nw and my whole mouth is full of ulcers. Even drinking of water is painful. Dun know when then can join u all for outing again??? Anyway wait for me to recover and i will be back. hehe!!!

ya man.

 

no crankin sound, cannot do the PUSHIE method liao lah. u dun even have the juice (battery power) anymore.

 

Ken is right..bo pian have to go mototrdaim lor.

 

if its rectifier problem..ask them change the new type with fins and heat sink.
