  1. jaw also has those peg ext. an a lot more for the birds. https://www.jaws-motorcycles.co.uk/models/?model=69#tabs-72
  2. thinking about an extra fan. already go a new radiator. an fixing to order evans antifreeze.
  3. first one . i sent the second first sorry. eteta <eteta@evanscooling.com> 11:10 AM (9 hours ago) to me, tech@evanscooling.com Robert: Due to the nature of this application just changing to Evans Powersports Coolant (EPC) will not decrease the temperature range you are experiencing. EPC does have a broader safe temperature range than conventional 50/50 mix and will allow modifications to the system that might help the problem. First change that would be suggested is to remove the thermostat and plug the bypass port. Because the thermostat is a 2 stage bypassing design without plugging the bypass port the coolant will circulate back to the pump rather than to the radiator. The bypass foot on the thermostat could be some if not all of the issue. If the foot does not close off completely the bypassing hot coolant dilutes the cold incoming coolant to the pump resulting in higher operating temperatures. This problem is normally evident at idle and low speed when pump rpm is low. Second thought would be to improve the airside of the system (difficult with this application) with better fan, and or increased core capacity of the radiator. These changes should come after the thermostat mods to determine the real problem. Thank you Tech Support
  4. emailed the guys at evans antifreeze. here is there reply. had several from them... Robert: Without the thermostat housing in my hands I'm at a disadvantage. First thought would be to thread the bypass hose nipple for a plugg of some sort. It does not have to seal 100% and a tapered pipe plug might put tooo much pressure on the casting, be careful! Second would be a plug that fits in the hose ( did not see a good photo of the hose configuration) again it does not have to seal 100% but must stay put. I have had car guys that crafted a gutted thermostat with a spring that held the bypass foot closed all the time, depends how clever you are. WHatever you decide to do, make it reversible. Sometimes completely plugging it off does not solve the problem and causes the lower hose to suck shut. This means that a smaller orifice (restriction) in the plug would help keep the hose inflated with some bypassing coolant. This is definitely trial and error testing.

  5. just found this forum. seems to be about honda blackbirds. i bought one last july with 22k miles showing in stock form. i have yet to ride it cause of my legs will not lift up to the pegs. just as i purchased the bike started having leg problems . severe stiffness. been working on get feet on an off the pegs . made some progress but not enough to where its safe to ride. any one know how to cure the overheating these EFI models have? radiator on the bike is like new. fan works but never shuts off when sitting still. i guess it will when riding. any way would like to be able to start an run the bike with out worrying about over heating. would evans antifreeze do the trick?
