  1. Thank you for your comments. The bike in now back form the dealer. The lubricated the rear suspension preloaded, what was blocked but did not do more. After discussing there with them their next trials to do/I should do to check the cooling process and quality I asked them: look, should I wait till next summer and try to overheat? When it is in red or boiling or the fan motor is damaged to to constant running in the summer, what should I do? Call some trailer or leave the bike on the road? Or just ride between my home and the dealer on this short highway? Who will repair the engine? I forced the service guy at least once to come down with me and look that radiator with his mobile light. I think it was the first time he really did it. I told him, I think I will have to do my own repair alone, however I got +1 year guarantee last month when I bought this bike here. The also sold it with Honda inspection. I read up the section from the repair manual, where Honda suggested if the radiator is 20% bad , replace it. Then he went to his boss and they said, yes we should go in the direction to replace a radiator. It did not mean, they will do it. I should order the radiator for online shop, what will be cheaper and come back when I have it. They could give me some support. About the thermostat, what they checked only via the OBD, they found ok. However I looked with thermometer the radiator gets also warm 55-60C° parallel to the hoses at the pump how they warm up. I read again the manual, the thermostat should start to open 80-84C°. At 95C°its lifting should be 8mm so to open good flow. Thy did not checked these parameters. They only looked, the OBD showed 98C°when the fan started and could cool back till 95C° idling the bike in the service, what they found ok. I told them, it is only part of the function if the fan runs well and it was only a idle RPM process when the engine generate low heat. On the other side it is normal to warm up the engine to fan operation in the garage. But when driving on the road in this early winter time the heat transfer should be more sufficient. If the radiator lamella is closed and can not transfer heat, or the coolant system is closed and works with high pressure drop, or a weak pump, or a not tight cap or finally a semi closed thermostat could weaken the cooling system. But unfortunately to check all these in today digital world is too much to ask. I hope if I buy a new cooler, it will solve this topic.
  2. Hi, Did you have these radiators to replace the old on in your bike? Did if work fine? If I am right the bike on the picture is DCT... Does it have beside the bigger radiator and its different inner plastic frame around also different coolant hoses and mounting parts? The fixation points I see on the top side are compatible between the manual and the DCT versions? Or should I consider also to replace some of them if upgrading to DCT radiator in my manual bike?
  3. Hi, The end of the story at the Honda dealer: their opinion is "this bike has so big motor it needs a bit higher RPM to run the coolant around. At 3000rpm when cruising in the village will be to low and not enough for the pump to circulate the hot fluid through the radiator. Therefore it is normal that the fans will run times to time even in 10 C° ambient when the speed is only 50km/h". Heavily damaged radiator lamellas in 20% and side bent or even closed lamellas in 50% are still ok in their check. Also how the radiator is warming together with the motor already from 55C° they defined as normal operation. They commented "my complain is not valid since the bike has two cycle cooling system so it is not a problem that the radiator gets warm before the thermostat should open at 80C°". I graduated at the technical university but it is a bit of high science for me. My opinion is that the engine should warm up alone till the thermostat opens at 80C° and this process can be monitored at the coolant pump hoses and on the radiator front surface with thermo camera, too. What I did myself. Earlier the radiator can get warm coolant only through the air bleeding hose, but it will only warm up the radiator cap region. This effect I could also see from lower temperature stages. But to get running the engine on 95C°cooling system in this early winter condition makes me worried about how it will operate in +35C° next summer? Or should not be a problem? I would not like to boil the engine or stop the bike there while ordering a spare part(radiator) and get an appointment at a private service (+2 months) who are willing to replace it. I also understand but cannot admit the opinion of the Honda dealer, who sold the bike with full maintained+1 year guarantee for me what was their marketing item but will not contain any high cost repair tasks. I took the bike there now 3th time for 2-2 weeks with service complains like cooling, rear suspension, breaks and bearings. But they made a small effort to repair any.
  4. Is here anybody who replaced the radiator in a manual bike for the DCT version? Would it fit if the plastic skirt is also replaced with it? Or are the other items to replace with it, too?
  5. Hi, Thanks for the hints. Could it be possible to install the DCT radiator on the manual bike? I saw the inner lower cowl should be also replaced for the DCT variant, which has bigger window and also a protection net.
  6. Thank you for your comment. My bike is manual. This morning I checked the warm up process from 8C again and scanned some point on the bike with thermometer. I found the the big black water hoses from the water pump are getting warm pretty parallel. Also the left upper corner of the radiator is warming too. Around 60C the thermostat seems to open and the radiator gets hot, as well. I read the thermostat should only open from 84C. The fan is on times to time when cruising on the streets today in the city in 10C, as well. I tried to straighten the lamelas, but cant work. 50% deformed. 20% destroyed.
  7. I checked the radiator is also warming up so early when the waterpump hoses are just 50C. When they get to 60C the radiator is full surface warm too. Its cap corner is warming from 30C. I read in the manual the thermostat should open from 80C, not earlier. When looking the radiator I was not happy. Is it a must to replace? Its middle and lower zones are the weakest.
  8. Is it worth to check if the radiator cap is full ? I have driven 250km after they changed the coolant. I checked the reverse tank yesterday and it was toped up to max. and clean inside with that green Honda coolant.
  9. Hi How does the normal cooling process work with this 1200F model2010? After having RC36 and RC46 for 10+ years my new bike starts the fan much earlier. Actually we have 15C outside and ridding alone on local roads and a bit highway (no city use or traffic jam) when driving for 3-10min in a village the fan would start, specially when I stop at a junction or at the gate when I got home. This behaviour is the same if riding with my friend (+90kg) My RC46 had side panels but could do more even in the summer. How will the big VFR12 works in hot days? I got the bike right now from the Honda dealer shop after oil, filter and coolant change. I have driven it just 300km, has not to much experience with it. The Tempr. bar display shows 2-3 marks bellow red when driving at least 80km/h. I shows 2 marks bellow when the fan starts. This morning I checked the temperature of the coolant pie on the left side connecting to the water pump and also the radiator with a laser termometer. I found in 2-3 minutes in warm up the pipe is already 60C and the right upper side of the radiator is also warming. Is it normal? I read in the service manual the thermostat should start to open to the radiator at 80C, not before. But I know, an early thermostat should only expand the warming time but not to generate more heat. Bit problem could be, the bike is stock but the radiator shows some wear/deformations on part of the lamella. Worth the open them a bit with a thiny flat screw driver? How to clean it in smooth way? (I asked the shop, but they couldn't do too much) How can I get access to check the coolant level in the reverse tank? Thank you for your advices! Peter
  10. How is the normal starting process of your bikes? Is it normal if after ignition on and the petrol pump has already finished its pumping up process in 3-5 sec but the exhaust valve servo motor and also some other electric device under the petrol tank, remain still loud like the music of some old PC games? The make this noise later when the engine is running, as well, how long I don't switch off the electricity. They have some wear for now or the new bike also preforms like this? 443282046_VID_20210930_1634161.mp4
  11. Thank you for your comments. Yes, the km stand I see only like a cosmetic feature when speaking about a 11years old bike with slight wear on the front disks and 2mm rear pads etc. I can imagine it has more run than my actual 800vtec-2006 with no wear on it. But I hope to go out with family it will fit better with the hard languages. I don't drive really sporty specially with my passenger, so its overweight won't be critical. Also I try to avoid the down-town and any offroads, but I was looking for a bike with massive power and vfr like technology. The CTX1300 was over my budget, why I could have changed my sport touring way of thinking, so not to buy a Kawasaki I just selected this Organic looking big Vfr12. I hope I will like it.
  12. Hi Guys, Could you give me some advices what should be important to check beside the normal signs of wears and damages, and of course the H factory call back before when looking for a used bike? Possible:18k km in a 11 years old bike??? Does it have any specially weak component? How can I recognise the valve clearance issues - if it was not real maintained? How often to maintain the front forks and sealings? Should it come with the replacement of the steering bearings (what is actual)? How is it charging the battery on idle and higher? What petrol does it like, 95 or only 98/100? How to open the 100ch engine setting to normal, how it came from abroad? Can a dealer really do it just setting its program, how they promise? Then is it like a 174Le model w/o handicaps ? The bike I found has a Givi high shield. I will check if it is ok. Except this, the bike is stock.
  13. Golden era:) The left one, should have been their patent for 25 years! Now I could buy a new one...
