  1. Happy Grumpy , i very nearly posted something similar yesterday. Same tenacity. LL2 posted some informative posts. RE , Duke overheating. It was caused by both a poor quality , under- powered electric fan , whose fan blades could detatch from the motor , and a very reistrictive shroud / deflector that encased the rear of the fan. This was an attempt to re-direct the hot , expeled radiator air , away from the rider , due to some riders complaining about hot legs , when in both trousers and shorts.The shroud design / outlet hole was too reistrictive , not allowing enough hot air out. So it ran hot. The cure is too ditch the shroud , and fit a better quality , higher powered electric fan. The process , and the fan details are on various KTM forums. In Thailand , if these mods are done , there wont be any problems. Some have gone the extra mile / kilometer , and added "Engine Ice" coolent , or similar.

  2. The steering dampers do help dampen out the shakes ( side to side ) at the bars. They wont help a wheel going down , in a pot hole , but do calm down the sharpness .Necessary ? . Well , thats for you to decide. But if it saves you from just one crash !. I have an Ohlins on my factory Aprilia and its a nice addition , but it was much needed on a 2004 Kawasaki ZXR 1000. Evil bike.

  3. Honda have thrown a huge amount of money at this engine , trying to sort out the reliability problems , so i cant see them releasing another model using the same engine.It has been changed so much , it became a "300". Point of intrest , the real capacity of this engine is closer to a 275 cc . Performance upgrades could be made , or simply buy a Kawasaki KLX , and go for a real 300 cc big bore kit.

  4. Two main reasons to use nitrogen . Nitrogen has larger gas molecules , so less seepage , and it is a more thermally stable gas , so pressure is more consistant regaurdless of tire temperatures. Everyday use - not really needed.

  5. Stevemercer , you are correct in saying the Ron and , to an extent , the Cetane rating can be raised by the addition of Ethanol / Methanol , however as Ethanol only provides about 70% of the energy that Gasoline provides , this shortcoming has to be propped up by blending it with the higher quality 95 Gasoline. It isnt totally sucsessfull though , as the lower specific energy released by E20 means you can use 10% more of it to go the same distance as Gasoline . This is why E20 91 is not recommended. And why many countries dont sell E20 , in either 91 or 95 grades. Ethanol causes many more problems than just perished seals and hotter running - as if we need the engines to run any hotter for christ sake. Wait a few years and the oil companies , and governments that forced this on them , will end up looking as foolish as they have over the diesel fuel fiasco.

  6. "Whats that all about" , you ask. Well , its marketing bull. As your page 93 clearly shows , E20 is of a standard so low as to require the 80% of petrol / gasoline to be the higher quality 95 octane fuel , where as E10 has enougth petrol/gasoline in it ( 90%) that you can "get away" with using it in some low powered /l ow compression engines in both 91 and 95 octane form. On any bike other than performance bikes , i would recommend Shell E10 91. Shell 95 " Nitro " is best for the higher compresion engines , and the expensive full fat " Benzine l" for the 2-strokes.

  7. The answer to this strange pricing system may be that 10 years ago there was very little choice in the bike ( and car ) market. Prices were high and choices were very limited , so you bought a Honda and keep it untill it died. The few people selling a second-hand bike asked a high price for it in order to recoup some of the money. Today thats not the case. Bikes are cheaper , in real terms , and choices are far better , with many bikes overtaking Honda on both quality and value , and many "new" makes such as Benelli , Stallion and Keeway coming to the market , offering great value alternative choices. With more dissposable income , people now decide they "want" another bike , rather than "need" another. So they sell their 1 or 2 year old model and purchase an upgrade. The resale price is no longer such an issue to many. Others , as you say , fall victim to reposession. Kf6vci , the Spark sounds great value. Did you buy it from Chiang Mai. If so , i saw the advert.

  8. I dont know who is designing all these generic bikes that are coming to the market recently ( such as the Stallions , the smaller Benellis and the Keeways ) , but they are doing a dam good job of making some very attractive , purposefull looking bikes , at amazing prices. Seems a very good alternative to a scooter , for a runaround bike. Stand by for some highly modified versions of these bikes hitting the streets soon.

  9. Benelli have shown their 250cc super-moto / super-motard at a bike show in India. Looking very sharp and Italian , and much like the model first shown in 2013 , the bike uses much of the mechanicals of the TNT 250 but with longer travel susspension. The Italian designed bike is expected to be priced around 120,000 Baht. I dont have any details as to when it will arrive in Thailand. Im unable to download a photo yet , but its on the net , so maybe someone can help.

  10. Thats the old air cooled "Long way round" bikes your talking about . Not exciting. The new 1000 RR,s are good. Im testing a modified one soon , for a company , so ill let you know. Hope my care home nurse looks like that.

  11. canthai55 , i replaced brake master cylinder piston and seals on my Platinum PX 250 ( not worn , just making a modification ) , Honda parts were a direct replacement. Seems both Honda and Platinum use the same supplier , many other engine / gearbox and electrical parts are interchangeable. Cant speak for Harleys , but the Itallian bikes ive owned , Aprillia , Benelli and Ducati , have never required me to use a bus or breakdwn truck. Need to add these to the Honda line. The KTM is spot-on HA HA.

  12. Opps. Yes , they ( MT 21 ) are more aggresive than i remember. facepalm.gif Honda went in 2009. My memory around the same time , it would appear. The AC 10,s are more suitable for the riding i do as i live very local to green lanes , and although road legal , they are not good on tarmac - dry or wet. Sometimes you have to use what you can get , at the right price.

  13. I dont consider the MT 21 to be much more off-road biased than the tires ( IRC ? ) that the KLX / CRF come with. I ran MT 21,s on my Honda XR 650R for green laning in England , but that consisted of tarmac / Roman road and general off-road riding. I used AC 10,s in the winter , that i now use on my Husaberg FE 450 green laner. 3000KM on the road / tarmac is good ( mine lasted 1600 - 2000KM on the 650 ) and points to them being a pretty good road tire , more so than 90/10. The problem is trying to get the tires you want in Thailand , without having to import them. You cant always get what you want. Hang on , theres a song there !.laugh.png

  14. For a number of years , Yamaha has had a far higher build quality than Hondas , and the re-sale values will soon start to reflect this. The Spark can achieve up to 94 KM / litre. The honda manages 64KM/L. Makes a small difference to ownership costs , but the Yamaha is just a better built , more stable bike. Great price on the shooter.
