hi to all babybladers,

 

does anyone here haf prob in startin ur bike w/o pulling choke after off engine for quite some time? i seems to haf tis prob lately leh, even after work (8-10hrs) later, i'll haf to pull choke in order to maintain the rpm. after bike warm up le tan ok already.if i turn the rmp higher, bike's rpm will go above 15k when warmed up.is there any remedies to tis prob?

 

wat will be the price range to overhual the engine huh? start to gif off white smoke when i use 15-40 eo so nw using 20-50 to temp lessen the smoke. i tink its time i should go for a overhual le. n wat r the things tat will usually be replace n serviced in the event of overhual huh?

 

as for the re-wrap of exhaust i might be able to hlp find lobang cuz my pipe has been re-wraped wif stainless steel casing. i'll keep u guys updated when i find the lobang.

 

thanks n cheers

It will help a bit. Becos now piston ring wear and tear, so leak hole and engine oil flow up to burn at the spark plug. If thicker engine oil, at least not so easy to burn away. And hence less white smoke. Also less burn away means more oil left inside, so dont need to frequently check and top up those engine oil that are "eaten" away.

 

Actually piston ring can be a small problem and also can be a big problem. If u dont intend to ride long, u can ignore it unless super lots of smoke. If u want to ignore it, the only difference it has with normal bike is that it create white smokes when u high rev and it eat up engine oil, so have to have the good habit to check and top up frequently. It only become a big problem when the wear and tear is very serious and it result in your piston scratches and caused huge difference in combustion compression ratio. U can feel the drop in compression ratio by the lack of power when u rev it, especially when accelerating at high speed. MAybe from 120 to 150km/h. If the performance is ok, then u maybe try ignore it, unless u intend to ride long, then solve it once and for all. I will suggest if you open it up, once u change ring, change the pistons as well, since open up already. Or else next time open up again, siong. Since each piston maybe 20-30 dollar only. Want to do, change together, save the labour fee.

 

Also now u have this piston ring leak problem, use thicker oil, it protects better. ALthough performance may not be as smooth as those fully synthetic which is thinner. It burns slower and helps to protect engine more. BUy those cheap mineral oil, put in your storage compartment in a coke or small 500ml container. Start by checking before every trip, the bike should be straighten before you check. Top it to the top line. Then if it doesnt eat much, reduce to maybe every 2-3 days, still ok, then maybe every week check. If everyday u must top up, then I think better overhaul, 4T not cheap. Cheapest mineral oil is 1 liter $5+. People 2 stroke bike eat 2T, yours 4 stroke eat 4T. Haha...

I never use my choke before on my R model. I never need to trottle to start. Just press button can already even in the middle of the night.

 

But the strange thing is bike become more difficult to start when it is hot. For example ride to a place, then off engine. Then when u want to start again, u need to press the button longer. Sometimes have to trottle a bit and press button. Heard this is common becos the air inside the combustion chamber is warmer, so thinner, so less air for combustion. Hence more difficult to start when warm.

 

BUt the rpm shouldnt shoot so high. Check your choke whether it is working. I suspect the choke wire is problematic. Maybe after u close the choke, it is still on, so the rpm shoot all the way up.

 

Have you wash caburattor and tune your bike, synchronise the caburettor? Try maybe it helps. Also try to clean the air filter, can diy or u buy from LAB very cheap only. Just take out the tank, then unscrew 5-6 screws of the air box, then replace with new filter. If old filter, borrow air gun from bike shop and clean it blow it from the opposite direction.

 

Idling should be 1.3k plus minus 0.1k. In the morning when cold, after u start, it maybe drop to 0.7k but engine shouldnt die. After warm up, it should rise back to 1.3k. If it always want to die, dont rev it hard. Just rev until 1.3k can already. Or 1.5k. IMagine inside the engine oil all settle at the bottom, u rev, it is very dry at the pistons and u might damage the pistons. I always set mine to 1.1k, so that bike is cooler. PLus mine dont die so easily when cold, so can set lower.

i had this problem when i first got my cbr l model. after a few days of ride, the power suddenly drop so much that i barely feel that it's cbr... i went back to check but they told me one of the spark plug is faulty. So changed and everything went ok again. Den a week later, it came back again.... i went back and they change again saying spark plug can have the chance of being spoilt after a week. so i just let them change since it's under warranty. During the 3rd week, gear 2 broke off, and i think it's stuck at gear 6 cause when i engage gear 6, a sound can be heard. den wanted to go back and do, the spark plug like died again. got so fed up that i ask them to tow it back. they changed the gear for me and also the spark plug for me. but this time i got so fed up abt the spark plug thing so i decided to find out what's wrong with it. i went to AGL at malaysia and asked them to do tunning and servicing for me. in the end, white smoke appears when they rev my engine. The boss told me either the piston ring or the oil seal are faulty. need to do a overhaul to check and solve the problem. i went back that shop, tell the mechician abt it, change the piston ring and oil seal and problem solved.

NB: the whole process took me 1.5 mths to solve.

20-30 bucks only for piston? woa... and i thought piston are expensive all along... i didn't know that... should be same price for all shops right?

 

 

i never use my choke at all too. it's jammed. but since i dun have problem starting, so i didn't change... but yeah... idling rpm shouldn't go more than 1.5k... mine when warmed up is 1.3k only. but cold is 1k...

 

 

white smoke also appears when the weather is very cold right? that time went cameroon highlands, white smoke came out when i start the bike in the morning. all other bikes got white smoke too. also, cos for me, white smoke appears only after it rained heavily, or when a bit of water went into the end-can. thats when i have white smoke.... other than that, no white smoke at all.

 

 

overhaul engine.... woa... ex ah~~ depending on your wear and tear parts... can amount anything up to 1.3k or close to 1.8k..... but also depend on which shop u go to... but it's gd to do overhaul if u wanna ride for long. it's worth it. no need to worry abt other problems in the future.

[RollinMao]

that time i asked a piston price at AGL and he quoted me 135 ringgit just for the 150cc piston... anyway i'm not riding that cbr anymore. i sold it liao... those white smoke most likely are vapour ba. and also mine is during service den got white smoke de... engine should be clean from water already...

yeah loh... i also have the impression that pistons are expensive. since it's rm135 per piston for 150cc bike...can't imagine price for 400cc...

 

must ask xiaogary where he got that quote from... gary dude~ u reading this?

 

[RollinMao]

i guess the price should be around there de. 150cc oni 1 piston... cbr have 4 piston so each piston is 100cc...

RollinMao is rite, especially juz after service. other tan tat,cool weather tan can c smoke.

it was quite obvious after servicing, change eo etc tan c white smoke when start engine tan mech said piston rings wear out.

 

so anybody can hlp explain hw come there is white smoke after service?

if its normal, dun tink i'll need to overhual le. can go up to $1.3k omg, gov gif bonus also not enough.gotta top up by sellin my ass man.

 

nw gotta solve the choke prob 1st.

 

thanks guys, ride on.

:cheer:

[RollinMao]

i'm not sure why but my guess is the white smoke are the engine oil loh... piston ring is to seal the engine oil de mah.... if it can't seal den it will leak to combustion cylinder and will like 2t loh... it's my guess though...

[xiaogary]

I also tot piston rings are ex. But thats the price. The price is when u buy and diy. Of course when u buy from bike shop, they charge u each maybe 40-60 dollars. Depending on which shop lo. Then after all the money they earn from the parts, they charge u labour fee somemore.

 

I have a fren who diy his overhaul on his honda bike. He do valve clearence, and change piston and piston rings himself, after buying the gasket and stuffs. Its during one of those night chats at kopitiam that I learned from him.Those pistons are not ex, rings are not ex, gasket are not ex, engine oil not ex, but it is the labour and when all these parts add together plus their profit which caused a bomb.

 

Just imagine they charge u each piston $50, each ring $25, engine oil $65, tuning $60, gasket $100, total $525 already. These does not include labour and other small parts that need to change. Labour for overhaul already $300 at least liao. Then if they do valve clearence together and change the shim and timing chain together, add up...confirm over $1000 for full overhaul.

haha...400cc piston? In XR4 lo, single piston, one big 400cc piston.

 

In our bike, its 4 X 100cc piston in a straight line. Thats why its call inline 4.

ha~~

 

lucky overhaul was already done just before i bought my bike. so no problem at all.

 

 

now trying to sell my baby. kinda reluctant having spend so much time and money on it. haiz.... got feeling for it already. next owner won't even need to do anything else to it.

 

oh well, shucks.

You shouldn't be charged seperately for pistons and rings as replacement parts from Honda you get the piston and rings together.

 

Also for Hurricane owners changing piston and rings is much easier as the barrels are seperate from the crank cases so you take off the head, lift off the barrells and can change the piston and rings, put barrels back on, head back on and done.

 

For Fireblade have to split the crank cases to change which makes it a much bigger job with higher labour costs.

 

Gaskets can be quite expensive but it all depends how many you replace I guess.

 

Also you guys should note that fully synth and semi-synth engine oil if they are the same grade (eg 10w40) they are the same thinkness. semi-synth is not "thicker" than fully synth if they are the same grade of oil. If you want a thicker oil then you go up to 15w50 or 20w50 in either semi or fully synth.

 

Mixing different weights and compositions of engine oils is not a very good idea either, don't put in semi synth and then top up with mineral oil, good enough to get you home if running low but not to leave it like that long term.

so what is the diff between semi and fully syn oil of the same grade?

Correct...normlly u can ask for the part number which include full set of rings and pistons if you want to change all when buying parts, but the shop sometimes buy separately which have different part number. So when the shop prestock them, their cost price is higher then they might charge u separately instead of the whole set.

 

Anyone have the book which show hurricane's part number? I only can find fireblade NC29 parts manual. But cannot find hurricane NC23 parts manual.

[Artistic]

hi guys, what EO do u guys recommend and plugs? and after how long den u all service? 3k ? 5?(mileage)

and btw EO need 3 or 4 bottles? sry just got my bike few days ago only

One is a fully synthetic man made oil the other combines natural oil with synthetic man made oil, hence semi-synthetic.

 

Synthetic is considered to be more "pure" and lubricates slightly better for slightly longer, most benefit seen in high intensity application such as tuned engines and racing.

I have the service manual and I THINK I have the full parts book as well, I will check through my files on the weekend.

guys i got a question..

 

went to the mech cos every gear my rpm will get stuck at around 5 and after awhile of stuck-ing(no power) den my rpm goes up smoothly

 

mech got my carb out and there are 4 needles which he told m,e the previous owner has got it and it is not stock..

 

why does my rpm get stuck at 5?
