90 jet - doesn't want to rev up but eventually does and hits 49mph solid
85 jet - same thing but better
80 jet - more bearable bogging but still does it.
NOTE: all plugs so far have been black except #80 which was a dark chocolate brown.
Stopped there for today.
Only gained a few mph on the top end, but TONS of torque. This thing launches to 45 or so.
It starts shifting at 6.5k RPM at first slowly working up to maybe 8k and this is where it starts to get into it's power band. 49mph is at 9k RPM so it might be top speed limited by being in too big of a gear for the speed.

Just as I suspected. Took it out again today with the 80 jet- was pretty cold today so it ran leaner and as a result didn't bog hardly as much. Still only gets to 50MPH however I feel tons of torque and I don't think it's shifting at the right RPMs. With some CVT work I think it could lift the front wheel and possibly hit 55mph. Also don't remember if I posted this or not but I painted it black and removed the front fender. Also removed the mirrors as they were too shaky with the little bracket things I installed on them.   |

Good looking scooter wish mine were like that lol Sent from my SPH-L720 using proboards It's rear disc, air cooled. Not sure what you mean by support. There's a single shock on the back left if thats what you mean. Yeah looks good without that front fender and the handle bar guard gone,did u tuck all million wires coming up too handlebars away?? lol If you look closely you can see the wires are wrapped in electrical tape all bunched together so they look sort of like the handlebars. On an unrelated note, I used the brights the other day and the button to flip them on just cracked when I used it. strange, but I superglued it back together. Doesn't really bother me much as that whole left sided control unit is like $15 on ebay. |

I've been noticing lately that the scooter will sometimes not turn over when electric starting and will just spin when I hit it. Is this a sign of a battery needing replacement?

Battery could be getting dead or possibly the "bendix" needs some greasing so it flies out like it's supposed to? I had a couple scoots make awful sounds while trying to e-start and a new battery took care of it..

So got the battery fixed up, and I finally tuned the jets and got the air filter sorted out.
I'm looking to upgrade the variator in hopes of getting more of the range of speeds in the powerband, because as it sits now, I can get some great acceleration for like 0-30,40 but I lose acceleration on the top end, (and top speed as a result).
The other thing I was looking into doing were spring upgrades. I don't know what I've actually got though. The stats in my sig are just approximated based on what I saw. I saw yellow springs in the clutch and a red torque driver, although these are fading and most of the paint has come off.
So to start with, What would be a completely stock take-off clutch engagement RPM?

Stock is prob something like 3-4000RPM for clutch engagement. Depends on pulley diameters and if the belt makes use of them too.

hmmm mine seems to take off somewhere between 4000 and 4500 but the springs are yellow. I'll have to look into that. I'd love to be able to takeoff at like 5 or 6k.

Red springs, clutch lightening, and making sure the belt makes use of "1st gear" could do the trick.

Ordered red springs. Hoca Vari should help with 1st gear.
