Prior to the piston debacle, I had switched from the stock muffler to a Tecnigas Silent Sport, upjetted to an 88 main jet, and moved from the 8.5 gram stock roller weights to 8 gram.
Since breaking in the new piston set-up, my gas mileage was around 36mpg (having added in WOT with more regularity:). My mechanic had maxxed my oil pump output, but I have, since break-in period of 1000km, adjusted that to just above factory settings. (see other thread in the Like502t section).
A suggestion had been made to switch from the Kymco-recommended BR8HSA spark plug to a BR8HS (different electrode). With this switch, gas mileage dropped to around 32-33 mpg. (of note, I had also, earlier in the break-in process, tried out an irridium BR8HIX which didn't seem to affect gas mileage much at all). I am back on the BR8HSA.
A couple of days ago, I swapped to an 85 main jet with a fresh plug to check for the mix. I will report back with an update after running a full tank of gas. It is very likely that an 82 main jet may be that to which I return, but we shall see after making a few more changes.
I changed out the stock torque/contra spring to the Jasil 15% (comparable to a 1000rpm spring) and per a suggestion from Moped Hospital upped my roller weight to just above stock (9 gram).
I know, given the feel of the ride, that the 9g is too much weight and have on hand a set each of 8g as well as 7.7g weights that I will try out to find the right mix.
Here, then, is the question (and I will likely pose this question under general discussion):
While I have access to a Milwaukee cordless impact wrench, I do not have a torque stick to moderate fastening the bolt on reassembly.
I do have a variator/clutch tool on the way from Treatland and a proper torque wrench on hand.
How do I properly use the variator tool on the Kymco variator? There are no "holes" on the external face of the variator into which to affix the tool. Do I grasp the metal teeth with the tool to hold it in place?
Any thoughts will be greatly appreciated!
