no excuses for having any problems now. Hardest part will be if I have to adjust the mixture screw. Australian models have that stupid coolant line running directly below it. They don't plug the mixture screw off just put the coolant line in the way.
Even without the carb heater in place the standard fuel mixture screw is in-accessible without twisting the carb CCW for access. The starter motor is too close for any tool. That is why some owners install an extended mixture screw.
Many Australian owners apparently do eliminate the carb heater & plumbing at 1st opportunity I recon. But they don't realize that the basic plumbing can be put to Better Use!
And surely it is not too hard to drain & refill the cooling system. Skid plate removed. Drain on the Bottom of the water pump into a clean pan.
The coolant can be filtered thru a paper towel or coffee filter & re-used even.
But What do I mean by better use, you ask?
How about converting the basic plumbing into a radiator By-Pass system for quicker warm-ups from cold starts & more consistent running temps in the cooler mornings and winter months? With absolutely no detectable adverse effect on the upper temps.
All one needs to do is run the coolant hose from the cylinder head thermostat fitting down past the exhaust pipe to the water pump housing using the shortest route possible and secured away from the exhaust pipe. And eliminate all of the rest of the carb heater plumbing. Done. Sound simple enough?
This will help to bring the entire engine temp up to 160f/70c quicker & stabilize it there.
Now one could even improve upon that. If you have the tools to install larger hose barbs into the thermostat housing & water pump housing to allow the use of 1/4 inch or 5/16 inch hose.
OH, Oh, oh! Grant, does this bike still have an Un-Modified LAM throttle slide installed? Top speed of only about 100kph?
ps, This might be a good thread to duplicate over in the Australian sub-section.
