well done dude!!! n u actually scrape yer knee slider on yer 1st time on track ...frickking awesome!!!

and did u notice any wild boars or monkeys or cobras or monitor lizards??? hahaha

yesterday a black pig rammed into a Ducati 1098 and the black pig was left bleeding on the tarmac and i was on my Daytona exiting outta of T5 and saw a big black pig right on my exit line,i had to sit up my bike n swerve,couldnt do it in time my front grazed the black pig n i used my right feet to try kick her outta of the way, the black pig didnt bulge but my bike wobble, i manage to control n rode back to the pits.. discovered my boot had slime,bile and splatter of blood on it and the whole lower cowling of my bike were grazed, damn super scary moments...

 

also there was a Bel-Ray sponsored RS125 with practically nothing except engine n fairing on the bike,heard its 150 with race magnets and all...guess that will be 1 awesome competitor for my RS for the next SMSA race... pity i didnt have my RS125 with me or i could have tested against her.

 

haha i saw what u type yesterday at FB. today once we reach the guy working there told my fren what happen immediately. the wild boar was cleared as i did not see any body lying around during my warm-up lap. heard from the guy the wild boar suffered a terrible death and some parts went into the sprocket n chains. one thing sure is irritating the birds just know when to fly when i'm on the tarmat, twice i almost hit the birds crossing in front of me. scraping my knee slider was definitly a experience and satisfaction for me.

As you say bro, tracking will be tiring. I'd rather keep my energy for track work only. Plus it keeps needless kms off my odometer and saves me worrying about riding back home when I'm shattered after tracking.

 

haha agree... after my 2nd hour i pit back and was totally wear out. shag to the max just dun feel like doing anything but be restless n sleep.

[lacrimosae]

: What say you, lac? I read your post about the bike being under the weather. Does this change tracking plans?

 

Well, I am running in my bike and yes bike tuning is way off.

 

I'll be in Paris this Thursday shopping at Dainese. hahaha... In Europe the prices of Dainese products are much much more affordable than in Singapore.

 

$350 for a mesh jacket that normally costs $550 in SG.

 

Track will have to wait but I highly recommend towing there. I used to ride up to the track and I really hated it. Putting mileage on your bike unneccesarily and the frustrations of going through the checkpoints in a suit. Ugh.

 

I'm getting too old for this sh1t. Just wanna ride 2 hours on the circuit, bug out and head home, napping in an air-conditioned van with my bike strapped down in the back.

Couldn't agree more.

 

Anyone else? I'm open to doing Tues to Thurs next week as well.

Actually, depending on your 2T premix ratio, you can reduce your 2T consumption.

 

Because you are premixing 2T into your fuel, lubrication will be consistent and fail-safe, therefore allowing a lesser amount of 2T to be used, while keeping the combustion cleaner.

 

smth new i learnt, so do u mean tt u dun have to lean out ur mixture to reduce e amount of 2t u use?

[quikslvr]

Before premix,my 2t can last about 2 weeks.after premix,my 2t can last 1 month.im using ratio of 1L : 15ml..

[vteclee]

have been leading a fast life this week. how do i notice it cause i'm using my 2nd 2t bottle this month... damn 1 month 2 bt of 2t i'm gonna be broke in no time.

[lacrimosae]

The lowest I have gone is 1L petrol : 11ml of 2T before I got a seizure from lack of lubrication.

 

The less 2T you use, the richer your mixture becomes. The more 2T you use, the leaner your mixture.

 

So a 1L Petrol : 25ml 2T premix ratio actually requires you to up your jet sizes at least 3-4 sizes. If not you risk getting a seizure from a lean mixture.

[Feelicks]

yea, wif my currently ratio, its a bottle a month... but im wanting to reduce e amount of 2t i throw in everytime... i always tot tt u have to lean down ur air/fuel mixture in order to reduce ur 2t ratio... less fuel going in to e system = less 2t u need in there as well, no?

[lacrimosae]

Couldn't agree more.

I don't work well with days of the week. I usually go by the dates.

 

I'll be in sg on 26 Apr.

I don't quite follow....

 

I'm assuming that since the volume of air/fuel mix entering the cylinder is fixed per stroke, if you lessen your 2T, the volume taken up by fuel would be higher, assuming the jet size remains the same, since the bore, stroke and venturi size remains the same and air volume would be the same. Thus the volume of emulsified liquid in the mix would be the variable.

 

Based on my plug chop readings and Mr Gunson (the Colotune glass spark plug), it would seem that the lower the 2T content in my A/F mixture, the richer my carburetion.

 

But I've been unchallenged for so long this theory has more or less grown roots in my mind and it's hard for me to abandon it.

 

This calls for a late night supper session to debate this over! hhahahaha...

tks. i hoped it could have better fc coz my fc is still lower than 20 after downsize the jet 2 sizes. Maybe try to downsize the jet again.

[Feelicks]

bro, it depends on wat throttle opening ur at most of e time... no point downing ur main if ur below half throttle all e time... also its e way u ride too? if ur into short burst of speed dan ur definately gonna consume more fuel on e whole.

 

down sizing e wrong jet can potentially blow ur engine too so plz b careful =)

i second this. Its pure common sense really. And ur reason basically just explains it all. Also, ive read about this in a few carb tuning articles so i guess u and all those experienced tuners cant be wrong.

Tuning isnt just about playing with the main jet. U can have the perfect main jet but wrong needle/atomiser/pilot jet combo and ur bike will still run like s**t and have terrible fuel consumption. Imo and experience in city riding the selection of ur pilot jet and atomiser is the most important, coz u wont be at full throttle all the time. And actually just fyi, the pilot jet does not only affect below 1/4 throttle opening. Assuming ur using a dellorto carb(i only noe abt dellortos), the pilot jet regulates a progression port, which is basically a teeny hole just behind the main jet opening. It provides some extra fuel to help in the transistion from the idle circuit to the main circuit. Meaning that it actually can affect up to 3/4 throttle opening. Based on my experience, a wrong pilot jet can affect up to the 5-8krpm range. Meaning the 5-6krpm monster tat has been tormenting many rs125 riders can actaully be vanquished with proper pilot jet selection.

take my word with a pinch of salt, but i really think that our bikes are not as fragile as the majority of us think. Take this into consideration. I ran my bike on a 142 main jet with a totally open pod carb for a good 2 weeks. and my bike was fine. It took the bike a ride from pasir ris to woodlands or approx 30+km running on NO 2T at all for my bike to seize. And to be really honest, the seizure wasnt really bad. Just had to polish up my block a little and it was good to go.

[Feelicks]

haha ok, taken wif a pinch of salt n pepper! =) guess our engines r really road hardy beast capable of churning out their worth in e most harshest of conditions. well, i'll b out of action 4 a couple of days... turns out my oil leak really is from e gear box housing meaning i gotta drop my whole engine n replace e gasket, changing e bearings n wat knot at e same time... total damage 600 bucks... there goes e growth n share package... haizzz

[Mdsufie]

Hey guys, is it normal for the bike to produce alot of smoke early morning when i start the bike? Im guessing that the 2t was set very high due to running in of the engine right? And that also the bike easily power off because the engine still new right? My mileage only 200. haha.

Wow thats expensive. A full bottom end rebuild kit cost 110GBP only on pjme... DIY!

tks for the advice. I usually ride ard 90-120 at 4th or 5th gear with half or more throttle opened. rpm range is from 7.5-10k. flat spot can be easily passed if below 5th gear. I feel the bike is quite ok, but just the fc doesn't quite satisfy me. Is there any prob with my riding style? I hope someone can give some suggestion on the good riding style for rs125.

[Mdsufie]

i still don't know whats FC. lol

[priller07]

i still don't know whats FC. lol

 

FC = Fuel Consumption

 

I believe it's ur tuning as u just got ur bike right. So the settings on some new bikes are crappy like mine way back 3 years ago. Maybe u can approach the DIY masters (no offense anyone!) and ask them to help guide u tuning ur ride or something. I'm sure they'll be more than helpful dude.

[Mdsufie]

YES! I wish to meet up! Do contact me at 81576796. I staying at woodlands.

[mesab0ogie]

my advice. Just ditch the 28mm carb asap and get a 34mm. Theres more satisfaction in tuning the 34mm.

[Feelicks]

yea, DIY's always e cheaper option... but i juz dun have e time to spare nor e tools to boot. i'd rather pay someone to do it reliably n have my bike down 4 a short while dan have it in pieces across a whole month not knowing whether wat im doing is rite. =)

[mesab0ogie]

Just a shout out before i place an order later today. Anyone got any brand new pistons for sale, im looking for one. Wossner/Vertex/Wiseco/ProX/Asso Werke only. Size 53.98 or 53.97 for Wiseco. Gona be using it on a brand new cylinder.

[Sub Zero]

Excellent news bro. How many ppl were on the track with you? How long did you go for?

 

I'm thinking of going this Thursday. Finally received all the items I was waiting for and have no more excuses! Anyone keen on joining? I'd want to get me and the bike towed up.

 

 

@lacrimosae: What say you, lac? I read your post about the bike being under the weather. Does this change tracking plans?

 

I think you can forget about getting Lawrence to come. For the past few years, his bike isnt ready. Forks leaking, tyres need to change, blah, blah. The best he did was reach 2nd link and realise his radiator was leaking coolant. Right Lawrence?? I'm still waiting for you to join the SMSA sponsored race!

 

 

In any case, you should try the experience of riding up atleast once. It's not that far, about 30 KM tops from JB customs.

It's fun to ride up with friends, stop over for breakfast, then move on to track. You atleast warm up your body and ur tyres.
