I am going to sleep now.....

Poppycock to say the least.

Common thing for Thailand. At a bus stop near Udon, I once stopped to eat at a small restaurant during a short layover. The chairs were the usual plastic with a back. As I was eating my meal, the chair broke from under me plumeting me to the floor. I was not hurt, nor did the restaurant owner ask. She immediately let me girlfriend know I would have to pay for the chair. I see the same chairs at Makro for around 90 Baht and she immediately argued for 100. At first I told her no way and she was lucky I wasn't injured by her defective chair. Soon a policeman showed up and the saga began to drag on and on until my bus was leaving. So, paid the gal her blood money and have refused to set in a plastic chair since. And no, I only weigh 95 kilos. Cheers....

The cable comes from the top, but I am unsure about the idle screw color. Will give a look when I get home tonight. Thanks for your help!

The biggest Honda carb is the one from the Honda Phantom,which is a constant velocity carb, i think its 33mm. If the carb has the cable coming out of the top, instead of the side its probably a 28mm NSR carb. If the idle screw is yellow than it is for sure. If its a flat slide carb, then you have struck gold.

Careful with the exhaust, bigger doesn't always mean better , nor does two pipes vs one...

The original carb has already been replaced by a larger Honda carb. Kawasaki keeps asking me if I want to change back to the stock carb, NOT. The bike starts and runs great and could use the exhaust as is....more in more out. Also, the stock exhaust has an unsightly dent and is deeply tarnished and discolored. Anyway, have seen several dual exhaust systems around on both the Phantom and the Boss. Sounded pretty good and looked great. Just need to find a vendor who can get it done. Will talk to more bike shops, maybe I will get lucky. Safe Riding!

I wouldn't mess with the exhaust without any prior modifications to increase power. Up in CNX jets are hard to find unless its something that also fits the Keihin PE28 carb...believe me ive been searching.

Thanks for the responses...the Boss currently has a noticeable piston slap and I have no idea about the mileage. The original speedo has been replaced and it currently says 9000 kilo. I plan on riding the Boss to and from work every day which is a ride of about 30 minutes at 90k plus on the Super Highway, as well as use it for trips around Thailand. I need the bike to be rock solid, which I don't feel is the case in its current condition. I bought it really cheap so I have some room to make improvements without getting too deep into my pockets. So, the complete build makes sense to meet my needs. I will stay with Kawasaki for a couple more weeks and see what happens. I would like to improve the exhaust with something custom though. I went to PK and they gave me a price but now are dragging their feet as well. Any suggestions on a good custom exhaust shop? See ya!

My "Boss" is pretty ancient but with the little bit of work its had it's giving 30K to the litre. They're pretty tough, shouldn't need a rebuild, perhaps as suggested, a little tune up and clutch adjust??:jap:

Hi All,

Recently bought an old Boss and want to go through the engine. Have been talking to the folks at the Kawasaki shop next to Siam TV in Chiang Mai, but they are dragging their feet. The bike has been there a couple of weeks untouched and they still haven't given me a start or finish date. Want to do complete engine rebuild including clutch. Know there are a lot of Boss riders around...what are your suggestions. Thanks!

What is your price and minimum order?

Hi, my new email address has been validated now, so personal messages will get through to me. Send me a PM if you are still looking for bulk virgin coconut oil.

Hey all,

Hope everyone had a good weekend of riding. I spent about four hours of mine in a shop getting a new electronic control module (ECM) installed. It was a much more involved project than anticipated by myself and the shop manager. Luckily, the person who did the work has a degree in electronics and was comfortable with tackling it. Body panels were removed, many wires were cut and re soldered, and conversations on the phone with the folks at JR Motors where I bought the unit. I was wondering if the bike would even run during the process. To the shops credit, the bike started first try and continues with no problems. The unit itself also performs as advertised. It really puts the throttle in your hand if you know what I mean. Before the install, the drive by wire always felt rather vague. Now it feels as if the engine is in the palm of your hand. Every subtle movement is met with an immediate engine response. It also seems to have taken some of the spooling time out of the JCosta making it's response to throttle increase more immediate. Cool.... The acceleration greatly increased especially from standstill through 90k. At that point it starts to struggle. This is much the same as before the install of the JCosta and ECM. I think this is just the reality of hauling my 200 pounds around on a 125cc. My oversize tires may also be at play. Top end is probably around 110 to 113. Hard to tell on the speedo and figure in the error due to the taller tires. Anyway, I am a happy camper with these changes. The PCX performs and rides much better and I can see riding it for a long time to come. At least until I "pop the top" at which time I will upgrade to the 150cc kit. Another 15,000 baht for a performance exhaust would probably be an improvement, but I don't think I will do that...at least not yet. Last word...if you do the ECM, make sure you are at a shop who really knows what they are doing...I was lucky!

mess 2 - said nothing !

tried top speed last night - got up to 115, still a bit more left, but had to brake for the t / lights..............

think might see 120 on the speedo.....

Wow...have you changed anything else? I have the JCosta as well and am very happy with it. But I also have upgraded the rubber to Pirelli 130/70/14. I was tired of the stock no-name tires sliding out from under me on aggressive curves and am very happy with the change. However, this is a lot bigger (taller/wider) tire than stock and I have seen no real improvement on the speedo. One thing to consider is my speed is probably a bit faster than the it says because of the taller tires. The JCosta and the tires have changed the bike in very considerable ways...no way would I ever change either back. The JCosta has given me a great improvement in performance between 40k and 80k which was what I really sought when I bought it. The tires have planted the bike in the curves (even two up) and given me the confidence to ride in ways the stock tires could not. I have also purchased the black box from JR Motors to improve acceleration and performance. To date, I have not had the chance to have it installed. Will post my experience with it soon. As for warranty, I had mine installed at Nat Honda in Chiang Mai. At no time did they mention warranty. Notably, my bike had over 10,000k on it at the time of installation and is now out of warranty anyway. If you have a torque wrench and are minimally mechanically inclined...do it yourself. I watched and it was very, very easy. No body panels removed, just open the case, take off the stock variator, install the new, put together and ride. Maybe some critical points to remember if you do it, I am told you should install a new drive belt, do not use any lubrication on the unit, keep things very clean, and torque the variator bolt down to 60psi. Disclaimer, I am not a mechanic but it did look very easy. If you are uncomfortable, pay the 200B and spend a half-hour with your local Honda dealer. Good luck...cheers!

If it is as fast as a Steed, I'd be interested.

Dealer in Chiang Mai tells me 120k cruise is very comfortable on the 250. Since they would not let ride one, take that comment for what it is worth. The 250 did look good and set well, just a bit too small for me I fear. I am asking the folks at JRD if they have any idea when/if the 400 will make the market. One thing, the staff at JRD did assure me that since the bikes are assembled in Thailand, parts would be readily available. I just wonder how many parts I would need!

Ouch! Price is a bit stiff for the product. The Lifan 250 V-Twin has been selling well here in Chiang Mai for the last couple of months. Have been considering a purchase but fear the 250 is too small for my size. However, the price for the 250 is only 78,000 B from JRD. Seems a bit much to double the price for another 150cc when the bike itself appears to be very similar. Am I rambling? Guess my answer would be yes if a test ride were available, or maybe a rental, that demonstrated the product stood up well under my butt. The price is another matter. I can buy a lot of bike for 150,000...and not an unproven (in Thailand) Chinese bike. Said that...

Hey,

Are you using the stock 6 roller set-up for your kit?

I'm back.

My appologies for not being around to answer peoples queries, emails etc.

I had to make a trip to Malaysia a while back and while there I suffered a serious illness and had to be repatriated back to the UK, where i had to endure some lengthy treatment and it has taken some time to recover. Anyway, everything is back to normal now.

Thank you to all those that expressed an interest in the variator mods. There are so many emails that it may take me some time to get through them all individually.

The mod for the Ruckus doesn't work for the PCX or the Scoopy, Click and Airblade for that matter. There isn't a lip on the variator face. Some other scooters from other manufacturers also don't have the lip, they have a washer that takes just a few minutes to remove to achieve the same result as the Rukus.

The kits are still available and if you're still interested send me a quick message and i'll reply quicker this time.

Best regards,

Scuddy
