OK, that's good, but it begs the question does that mean that the plug needs to be removed immediately after coming to a fast stop, or is the fast stop itself enough and it's then OK for it to cool off?
@Gary_in_NJ, OK thanks for that, makes perfect sense. In other words I will be taking Rutty's advice and not bother about the plug till the end.
@Ruttly, at the moment I am jetting the carb but I'm not having any problems and I'm not going to get as intricately involved as IslandRoad has recently, the bike is running fine and I'm happy. Having said that though I want to take a step back and do my best to *slowly* do some jet tweaking over the next few months.
Maybe I can convince you to do a more detailed analysis of how you precisely determine the jetting. My experience so far is that having bought the bike in showroom condition having ridden only 500 miles in 11 months, when I got it, it was running very very hot, tiny shutdown poof, but annoying low speed surging, but it was the heat that bothered me. Did a pilot mix adjustment from what it was on 1 3/4 to 2 3/4 and that instantly solved the overheating and surging problem too. So all was good.
I decided to put in a 55 pilot from the standard 52.5 which took the pilot screw back to 1 3/4. However with my limited experience I didn't really notice any difference between the 52.5 adjusted correctly and the 55 adjusted correctly, while some people suggested that the 55 pilot (I'm at sea level btw) was too much I left it in as I was about to install a Dyna which would need more fuel anyway.
After putting on the Dyna and before riding the bike I installed a 150 main from the standard 145 because there seems to be a general consensus that 145 is definitely too small. I did a lot of the roll on WOT drop back an eighth of throttle looking for the telltale surge which was not there. Nevertheless I still went for a 150 main. I'm still wondering why the 145 did not give me the surge when backing off WOT an eighth. I marked the throttle position from slack removed to WOT and all the in-betweens. So that's a question for anyone, how come that 145 is considered definitely lean even at sea level but there is not indication of this for me at least.
I also did the spacer mod and as I am in Australia I have the notched needle. I was surprised to measure the nylon spacer at 2.5mm as I had been let to believe it was more like 4 or 5 metal washers or 4 or 5mm. It began on middle and as the notch difference is 1mm that means that just moving it to the bottom notch and leaving the spacer was almost the equivalent of thinning the spacer by 1/2, in fact the difference was only a 1/4mm and I'm pretty well certain that absolutely no one no matter how anal is ever going to do a 1/4mm needle position adjustment.
Now I don't know if the AUS needle is the same as the US needle (without notches) but it has notched machined into it, OR if's it's a different needle so I don't if the single clip position on the US needle is equivalent to the middle notch in Australia, or not. I don't suppose anyone can answer that without a side by side comparison. In the event as it is also general consensus that a bit more gas on the needle is definitely a good thing. Removing the spacer completely (for US) is bad for some but half a spacer is pretty well de rigueur.
If you want to illuminate me to your very specific needle fine tuning then I'd look forward to reading it.
OK so where I am at the moment is that I'm not unhappy with how it is there's no surging, no shutdown poof, no overheating, and there's a tiny bit of throttle shut down pops and crackles which I deem a good thing because I wasn't getting any of that before the dyna and that meant to me that it was not tuned to it's best because deceleration pop is normal.
Right now I'm wondering whether I should go back to the 52.5 pilot and put the clip back to the middle with the spacer removed completely meaning that I'm giving it a further 1.5mm from what it is now (bottom clip with spacer) or not.
But mostly I'm concerned with how to tell the difference, what to look for because as I said, I'm not even seeing a difference between the 55 pilot or the 52.5 pilot as long as they are both adjusted properly.
