  1. Yep NGK BPR5ES is the correct plug Base gasket should be ok.
  2. I remember when I bought mine I rang Dave Cooper to ask exactly the same question. Its a great bit of kit, If you have roof rails on your FL then attach a strap from it to the handlebars and it really steadies it up.

    gasser heat issue

    Cleaned up well, it should run like a new bike. 43 degrees that's too hot to ride, Its 18 degrees today in UK. I've never felt that type of heat except when I worked in a power station it still wasn't as hot as 43 though but at least you could go outside to cool down. How far away is the forest fire from you? On a lighter note, Your work bench gives the impression you've been busy (just like mine) but I hope you have used correct the tools and not the hammer and grips to fix your Gasser🤣 Enjoy Canada day and be careful.

    gasser heat issue

    The piston and bore look ok. The inner O-ring looks very poor and I reckon it has leaked hot gas into the coolant. Its not so clear on the photo but the top surface of the cylinder looks burnt/pitted, I hope it will clean up well. It may be worth turning it upside down onto an sheet of Wet & Dry sandpaper on a flat surface and polish it. at worst it may need skimming. What is the condition of the cylinder head looking like?

    How many times have you changed the oil since the first contamination to flush the bad stuff out? I'm hoping you only had it happen once and it 's just some residual coolant still trapped in there. After a miss-hap my bike was fully submerged in a 3 foot deep stream everything was full of water (Tank, Carb, Exhaust and Engine) It took about 4 oil changes to to flush it out. It looked like somebody had dumped a shopping trolley.

    Excellent, Hope you get it sorted soon.

    gasser heat issue

    "Am I correct that the thermostat should read Open Line, no resistance at room temperature?" On my wiring diagram power from the generator to the fan is halted by the Thermostat which is open line or circuit not made. Open line is high resistance so no current can pass, When the thermostat gets to hot temp it should switch to closed line, circuit made and low resistance to allow current to the fan. Does this make sense?

    Any excessive pressure in the coolant should blow out of the rad breather hose under the tank. Check that the hose is clear and not kinked. The only other place it can go is via the pump seal. Excess pressure in the coolant can be caused by a leaking cylinder head O-ring, can possibly be a result of overheated engine. Test! Fill the radiator to the brim, Run the engine without the rad cap and look for bubbles coming up. If there is then you know the higher pressure of the cylinder is getting into the coolant and need to replace the O-ring seals. The high pressure is more than the Rad cap or the Pump seal can hold. 40 degrees 🥵 in that heat I would expect the fan to be running most of the time. the fan on mine comes on just after when the radiator gets is hot to hold your thumb on the top.
  9. If you don't have a spare wheel on the back then you need the "Van / Motor Home Rack" I have one one my Yeti. and plenty of clearance between handlebar and back window.👍
  10. I've used evo-stick and it worked well. It is petrol based so is can be removed easily with petrol. Also I've used double sided tape its easier to feed under the edge of a sticker and press down firmly, then trim off the excess with a knife.
  11. The bike was about two months old. They replaced the generator, pickup, wiring loom and CDI for free.
  12. I had a CDI issue with an Enduro bike I was told there was no warranty for competition bikes, but if it was road registered which it was then there is 12 months warranty.
  13. Quite certain there are only 2 available; genuine GasGas and RQF. Both are made from Aluminium. Re-assuringly expensive.
  14. When you say a spanner has no room to turn are you using open jaw spanners? If so then I think you need to use ring spanners. or Combination spanners which are ring at one end and open jaw at the other.
  15. Confirmed the seal is correct. Some checks you can do; Run the engine without the rad cap on and see if any bubbles appear, if they do then you will be getting extra pressure in the cooling system and the water gets forced passed the pump seal. The Cyl-Head O-rings will need replacing. Make sure the rad cap breather is clear and the pipe is not kinked, when the water heats up the extra pressure can't vent out so again the water gets forced passed the pump seal.
