That's a sweeeeeet looking bike, I wish they were a bit bigger and i would buy one in an eye blink.

They sound fantastic too, i thought 'The girl with the dragon tattoo' was riding one,but that was a Honda CL350, great sound too, really makes the film.

I thought mine @ Bt.3800 to be a reasonable price.

Mine is the same, I paid 3100 baht. Catalogue special. Thai Watsadu do have specials. I bought a 7" Makita angle grind there the other week which was a thousand cheaper than anywhere else. They have 4" Hitachi angle grinders at the mo for 1100 baht. I paid 1990 baht for the same at Thai Watsadu in Phitsanulok 18 months ago. You win some and you loose some!

Hardware House house has 4" Hitachi grinders for Bt.919 at the moment.

Well, the guys who actually made the bike, say it is a CB350. Need more proof?

I'm out in the sticks (Isaan) and there's not a lot of choice up here.

Not sure if you're near Udon or not, but Tool Pro stock a number of compressors.

I'm over near Chaiyaphum, but I've a mate over by Nong Bua Lam Phu so I guess be a good excuse to nip over for a jolly...

Thai Watsadu aren't the cheapest place to buy air compressors. If your not in a desperate hurry check around. Sometimes you can find catalogue specials with good discounts.

I got the same one at HomePro for 3500 baht last year- it was a steal and a great thing to have in the house- I might upgrade to a larger-capacity compressor in the future as it's better for running air tools, but that little one is very handy for the reasons you already mentioned (and I'm anal about tire pressure and check and adjust it before every ride;)).

I'm not really in a tearing hurry - well not quite yet, I've got my sister coming over for a holiday when I get home from work so I guess the small lady will keep the shed locked til she's away, but I'm dying to get on and start hacking things up once I get time, so I'd like to get something organised. I prefer air tools to electric tools - a bit more of an outlay initially, but they last forever - so I'm after something with a decent output and good size receiver to run these. If I have to pay a little more to get something a bit more robust, I'm cool with that too - you get what you pay for with tools and buying crap is a false economy in my book. So cheers for your suggestions gents...I'll have a trawl around these and see what they have on offer thumbsup.gif

I was wrong! The little Hitachi was 890 at Thai Watsadu....so I bought one! It's almost identical to the one I bought at Phitsanulok for 1990! So what's the real price of these 4" angle grinders?

Regarding tool service. I have an digital arc welder one of my Chinese suppliers sent to me and the damn thing has a fault...I can't strike an arc. The local shops I go to for stuff won't repair anything they haven't sold.

So, where does one go to get a welder repaired in Pattaya?

Mine looks better but this one is legal!

265k air cooled fuel injected. That means its more powerful than the old mikuni carb?

Sent from my iPhone using Thaivisa Connect Thailand mobile app

I don't have the specs of the new SR at hand, but I would imagine that the power difference is minimal. Better fuel efficiency yes, but power....Nash

Give yourself a nice present and get a Keihin CR38, then you'll feel the difference. :-)

On a side note: on some SR groups people were saying there's a 50th anniversary SR for sale at 285k...100 bikes only.

Anyone knows what the story is? ...since it has been in production since 1978 (500 model), that would make it 36 years old this year...?!?

Yamaha had a 35th anniversary SR400 last year.

yamaha 50th anniversary not SRs anniversary ;)

black is the limited edition white is the normal version.

Omega whats the diffrence between 38 and 41 mm? why size diffrence?

I hear the power diffrence will be minim if only change carb, I would need to 'tam kruang' do the engine some how.

My garagist told me around 10k and he ll turn it up from 400 to 540cc something lol

The more power you want the bigger size (more fuel) but only to a certain extent, these things have to be done by somebody that knows.

If it was my bike, I would not remove the FI and fit a carburetor as the FI system will constantly monitor your engine load and and surrounding air pressure and adjust the fuel blend accordingly.

A cab is difficult to set up 100% and not many can do it. It will also burn more fuel and not all of it will turn into HP.

I bet the Japanese will make a lot of kits for them, so you can likely soon get a 500/550cc big bore kit and perhaps another cam.

I asked Yamaha Pattaya today about the horse power on the SR400 and he didn't know, I said 27? he said thereabouts.

So 35 HP should be within fairly easy reach which based on experiences on my own SR500 (many years ago in Denmark) should give you a top speed on about 150-160 km/h flat on the tank depending of the size of the rider off-course.

Shit man, now I am getting interested into getting one toobiggrin.png

Ohh, now I understand!

38 and 41mm are the diameter of the carb. Bigger diameter, more air/fuel for the engine.

If you change the carb it is advisable to change the exhaust too, so that the engine can breath better.

I would not do anything to the engine itself. The stock engine is bomb proof as it is. I know of several who changed to expensive Yoshimura pistons and cams, just to end up with a seized engine. In fact, just had one on the last ride this weekend.

You've been warned! whistling.gif

Well this has sat in moth balls due to a never ending fuel petcock leak problem, as well as a bad choice of tank with small capacity (bike only runs on 95 Benzine which means Iam heavily restricted to ride destinations of less than 60km of a handful of petrol stations on sukhumvit road).

Sooooo.

Engine is out for a capacity increase from 400cc to 540cc.... and the original tank is going back on.

The above is all true, however, if you whack a larger diameter carb on, what actually happens is that for a given volume of air passing through the venturi (ie cylinder capacity x rpm) the airspeed effectively drops, and when this happens, you lose the carbs ability to pull more fuel out of the floatbowl and mix it all up before firing it into the cylinders to be burnt - the effect of that to you is sluggish acceleration (compared to the smaller diameter carb) Where you will see the difference is at the top end - as long as the carb is jetted properly, you will see/feel more grunt at the top end...so a bigger carb is not always better - depends what you want from your bike...
