KRS1

thai sites are reporting that it has been unveiled.

glad they finally changed the windshield.

wonder if its going to be 30 or 35 hp....waiting anxiously for pricing between YZF-R3 and CBR 300

just in time for you krs!

specs stated 32 hp before for cbr300 and i dont think so yzfr3 coming anytime soon.

its a nice coincidence, but im still trying to decide whether 287cc is going to be worth it....at the motor show the Yamaha R15 (150cc) was on display...its going to sell for 90,000 baht.

So i think that will put the R25- R3 at around 140-160k baht....i think yamaha will probably put pricing somewhere between honda and kawa.

The R15 looks awesome for a 150cc bike !

ok, now to find dual rocker arms...

coffman's exhaust dont sound too bad either and are also really small.

cb 500

I don't know much about bike upgrade stuff, but, can you source "roller tip" rockers for your application ?

i dont know...but...'roller tip' rockers just sounds badass !

was just looking at titanium valves and springs last night.

But is titanium meant to be for prolonged/daily use?

I think at a cost/benefit ratio for your intended use, Transam advice is good. SS plenty good, with Ti keepers and retainers.

Only benefit to Titanium valves for a street bike - or any other - is a reduction in weight, so a corresponding lighter valve spring can be used and still allow adequate valve return

By the by - what do they want for a titanium valve ??? I am sitting down !!

it was like $150 for a set of 6 on ebay... just skimming prices, those are for engines with 7mm stems. Although its a possibility they can be sourced for a cbr1000 to be used on the 250.

just let it go dude, people like this will always exist...

Should add that over revving to the point of valve bounce will be very detrimental to all your valve train, thats why you can buy stronger springs if you want to increase rpm.

Usually titanium locks and keepers are used. Stainless steel valves and descent springs do the job. Increased tension (poundage) springs can cause premature cam wear.

PS. Synthetic oil a must.

thanks.

i saw one of these on a cb500x and was expecting ear deafening volume....but when he drove away, it was not loud at all.

4500 thb is also a steal and i was so happy with my 5000 thb thai made bluekraft slip on on my cbr500r too. Money does not always brings happiness

Dont want to pay 40 k for a Moriwaki, Honda might release a more powerful bike maybe a 1000 cc bike next year so i might trade in again.

all my mods have been free so far, except for some work with a cutting torch, and 2 feet of copper cable.

You are very lucky the valve didnt drop and destroy the engine. Did you disable the rev limiter previously?

yeah thank got it didnt drop.

No mod on the rev limiter, its the stock ECU.

Fascinating posts ..... a blown motor is like a detective novel for petrol heads!

Hope you get the parts and are back on the road soon.

I have a theory that racers and tuners improve the breed by stressing components to breaking point and hopefully the info gets back to Honda - and so eventually the engines get stronger for us 'normal' users who keep things stock.

A bit OT - but in a standard state of tune is the 250 motor reasonably reliable?

I would say yes, for normal riding and long distance travel....and not redlining constantly its pretty bulletproof, except for the cam chain tensioner which is prone to a lousy ribbon spring inside, even then it wont break down, itll just be loud clacking (not ticking)...the plunger only travels one way, so the tension wont loosen.

The clutch has minor slipping issues every once in a while, but thats contributed to hard riding/choice of oil and isnt a serious issue, as all bikes at some time will slip...But after you push it hard, it hiccups.

The rear brake pads wear a little too fast though, im on my 2nd set within a year, but thats do to my riding style.

The gearbox is getting loud when shifting also. But this seems to be the case for all small displacement hondas with manual gears.

This bike is heavily detuned, once you remove the things honda did to detune it...its a totally different bike...and makes the need to upgrade to the cbr 500 pointless...unless of course you derestrict the 500 as well.

semicheap to repair if the dealer doesnt rape you. All the repairs in this post will cost 2300 baht, but they know im keeping an eye on them and what they change/charge. A normal person wouldve gotten charged for a sparkplug and air filter and CCT as well, bringing the bill up to 4000 baht or more.

another ticking honda lol...

check my thread for a clue.

i redline my bikes. In the city or not.

Looks like we've got a Biker Great and Hero amongst us.

Stand back in awe lads.

its a bit hard to believe as well since most of the <deleted> day bkk is a gridlocked traffic jam that someone can go around redlining a 650 in 1st 2nd and 3rd without gettin getting splattered like a tomato in the first half hour ................

life doesnt revolve around the sukhumvit area ...

1) kaset nawamin,

2) ratchprasong over pass,

3) ramintra,

4) ramkhamheang outbound, after outer ring road.

5) srinakarin.

6) king kaew,

7) outer ring road feeder road,

8) rama 4 (or was that 9),

9) chalerm prakiat (udomsuk after crossing srinakarin)

all these roads can be redlined, and thats just one side of town.

went to inspect the bike today, amazingly they were going to throw the old shim back in without reshimming all of them back to spec as requested...amazing (maybe they were trying to save me money, but they could have let me know)

failure was due to one missing side of the cotter valve, dont know how it went missing....side to side play and the shim slipped out...bike has been ridden hard for the past 25k kilos, and just now failed.

so it needs cotter valves and a new retainer and shims...gaskets etc....so i have to wait another week to reorder the shims fark !

#13 (cotter valves) & #11 (retainer) - see below

actual valve face and seats looked ok, cylinder barrel wasnt scarred...piston was extremely carbonized....theres a YZF-R3 in my future sooooo...left it as is. with the airflow modifications i performed i was curious how lean it was running, after seeing the piston - its not running too lean at all.

sliders should be made of delrin, most in thailand are made of abs...no metal on the edge please.

18 hours to go ...

Have you tried CREEMA COFFEE half way up Loykro road they are fantastic VERY busy but worth the wait try them you will not be dissapointed.

yep, the cappucinos will light you up quite nicely too

stay away from ST powder coating in cnx, going on a month now and buddies parts still arent finished.

> I believe it is not against Thai law to ride a motorcycle on the sidewalk.

The OP obviously has been long time in thailand

Eight years in Thailand, and the first time I was walking down the sidewalk with my girlfriend, her sister, and her sisters 7 year old daughter. A motorbike came down the sidewalk and I stopped him and tried to pull him off, and my girlfriend kept shouting at me "no, no, you go to jail" or words to that effect.

Most falungs and Thais ride their bikes on the sidewalk. It's an alternative to to sweating off your testicles in a traffic jam. You're lucky you listened to your girlfriend otherwise an m/c taxi gang would have kicked your a**. This is not Ireland it's Thailand and the sidewalks belong to bikes. Next thing you'll be complaining about the potholes!

You come down a sidewalk on a motorbike near me, and there are no witnesses, I will personally pull you off it. I am not just being a keyboard warrior here, I really mean it.

what happens when you pull the wrong person off their bike, and they stab you in the side of the head ?

i know a farang (Brit) that bought a drill to use once then returned it.

its not limited to thais

Thai bike forums are saying that the Tricity is definitely going to be sold in Thailand and will be priced at 100000 baht.

For tax purposes I wonder how it will be classified.

me too, ive been wanting to build something like the T-Rex for quite some time now.
