It leaves from stop with authority- loke the 7.58s aren't an issue. Picks up speed to 45-50 very quick too, feels stronger than MHR with either pipe. Didn't dare more than 1-2 seconds wide open, but adding throttle at 45 doesn't add more acceleration. I think the main is still rich but will check plug manana.
Sorry I didn't port map it.

Greetings:

Couple pics. Tach installation looks a little Ghetto, and the tach itself is still reading 2/3 of actual. Hopefully Mr. Mouse can help sort that out.The TinyTach hour meter now shows an hour instead of minutes. I'll sort out the jetting and report soon.

The TTO sensor wire and the new +1500/2000 spring are still coming, but I had to get a Garage Fix. I decided to swap out the 7.58 gears for 8.44s. A Forum Cognisenti for whom I have great respect had told me that the 7.5s might actually be holding me back on top speed. For sure they don't help the zero-to-ten pickup, although I still believe their effect on midrange acceleration is minimal thanks to the variator CVT system. Building on what he's told me, I have concluded that excessively tall gearing prevents the variator from maxing out. Running at something less than maximum causes additional belt slip which actually cuts down on top speed, even if the system is adjusted to put the engine at or near its maximum horsepower. This is true on level, windless runs. The taller gears do give bragging rights if it's a windy day on a downwind or downhill course.

So here's Flash's current setup:The first step is draining as much oil as possible by parking over Ms. Wheelperson's priceless Persian Rug, and leaning the scooter over for like...an hour or so while the trickle drops into a handy Ming vase.For the record, on this occasion the garage floor Spottage was minimal. Kitty Litter, ground into the floor with a jackboot, then swept, produces pretty good results. Plan ahead and use a couple rolls of paper towels unless you're feeling lucky, Punk.This is how my gasket came off. You probably won't see this if it's the first time you open up the trans case. That's because foresightful Wheelman ALWAYS generously slathers every gasket he installs with Hi-Temp Harley-Davidson Multi-Purpose grease. Every gasket I've removed lately has come off like Buttah. No need even to wipe, really.

Take note that the 5 bolts that hold the trans case on are of at least 2 different sizes, and need to go back where they belong. If you insert them and one sticks out too far while another is almost flush on insertion, you've made an error.

The new gear set (Not quite visible in the pic) has a slightly smaller countershaft gear and larger Axle gear than the one in situ. By the way, I did remove the exhaust for this swap, but you don't even need to do that if you can get to the axle nut on the right. the wheel stays put on the brake shoes, and the axle slides out to the left.Another shortcut I use is clutch removal without taking off the kickstart case. If you can squeeze the rear pulleys and push the belt to center, it's possible to slide the clutch off its shaft without taking off the front pulley outer shift.

As it turned out, I decided to increase the vario load from 27 to 33, anticipating less gear "drag" from the 8.44s. It appears I was right. A test ride produced Stupid-fast acceleration despite still-untuned 28mm OKO. It four-strokes pretty badly as the throttle is cracked open. I'm still not for sure if it's rich or lean, but when the TTO wire arrives, I'll check the spark plug and decide to go up or down from the 150-ish in there now. But despite that, for 80ccs this thing is a head-snapping, easy-wheelie machine.

For the moment, Flash goes back to its corner.

How do you like the new metzler me1 tires? I like the look of them - what size did you get?

Greetings:

The 90/90 Metzlers are perfect in terms of holding air and preventing my shiny Met rims from getting scratched by pavement. They're black and uh... they have tread and writing and stuff on them.

Sinceriously, I'm not able to compare handling performance at the limits because I simply never approach the limits. I leave performance assessments for people who don't ride like arthritic grannies.

Had time check out my spark plug with the 155 main/50 Pilot (I think...).The wet, black insulator (and remarkably clean thread bucket!) confirmed my suspicion that the setup was WAYY too rich. Just about an hour and a half or about a full tank consumed. I installed the 150 main, as the low-end and idle tuning seemed pretty good.

Next I dug into the rear pulleys. A kind Forum member just supplied me with a pair of Taiwan's finest springs; Yellow +1500 and Red +2000. Pulled off and dismantled the Kymco ZX pulley and surmised that the Malossi blue +2K spring was just as thick as the Tai version, but considerably shorter.Note that for some reason, it's wound left-handed instead of right-handed. I'm not sure of the purpose or significance of this.

Baka-san correctly pointed out that the Wheelman method of assessing spring tension (Just squeezing the pulleys together using formidable Wheel-Thumbs...) was not accurate. So I set about determining a slightly more Scientific method. Enter the Counselor bathroom scale, and a pair of half-inch sockets:I just leaned on the bathroom scale until it just kissed the sockets, noting the numbers on the scale.

The result? The red Tai spring read 135, confirming its stiffness. The yellow read 110 pounds at the same compression distance. And my now-retired, short Malossi "+2000". Only 90 pounds. This would explain why the revs were still so low despite only 27 grams of variator load. If I could've found my stock Honda spring, I would have tested it just for comparison. I'm putting this in Tech Docs just for fun.

Just had time for a short ride, and confirmed the higher variated RPM set-point despite the increase to 33 grams in the variator. The softening power was due to 4-stroking and is gone, I suspect thanks to the 150.

Hello Mr Wheelman
Malossi doesnt make a blue spring for our bikes. That is a Malossi spring for different scooter.
Makes me wonder how long that has been haunting you. Especially with those tall gears you been running.

Remember your trans setup is going to be completely different with the 8.4.1s might want to start with the 1500 spring first.

red white and yellow isnt it ? i have had a red malossi give up its tenshion aswell .Now im running a koso 2000k spring

Greetings:

I did install the yeller one. I had swapped up to 33 grams anticipating the need for an earlier shift point with the 8.44s, and left them there - mostly too lazy to pull the front cover yet again. Seemed pretty close, but no opportunity to stretch its legs.

Verily, the short spring which WAS purportedly for the Dio might have been a Plague on The House of Wheel. It explains low RPM Premature Variation with less than even the +1500 Tai spring. Also, my particular Polini vario has a pretty flat and shallow ramp plate. Not sure if/how to get the steeper one to try.

have you seen the ramp plate on the malossi vari its almost flat aswell.I thought it was the wrong one when i got it but it works great just a little harder to tune than others .

Greetings:

What diameter are the Malossi and Naraku drive faces? Polini-for-Ruckus is 94mm.

My daytona measures 89mm and the Malossi 90mm

Greetings:

Thanks for the specs. That size won't work as well with a ZX back pulley. The longer belt needs a bigger diameter up front or it can't go as far into Overdrive. Do they both make a For-Ruckus version?

Ive run both with zx setups and have hit 69.9 with 8.44 gears .My belt rides high enough .

Greetings:

I also endorse the "One change at a time" Rule. Unfortunately I often fail to follow it.
What RPM were you turning to shadow 70? Maybe a few more points of gearing would've put you over?
