whats the best Main Jet size for standard air box but for more speed ??
-
depends on altitude where you live or drive scoot most of the time.
82 is safe bet
-
will 85 be okay im in the south west ??
-
I'm in MI and upjetted to the 85 with stock setup and never noticed a difference. Maybe the different altitude will make a difference, but either way it would probably me marginal if any increase at all actually occurs.
-
Your in S.W England right? If so the 82 jet is as high as you need, any bigger and you will just run rich and end up with less performance than you have now.
-
Kenho hows the scoot start in this michigan weater when its below 30 does it start ok for ya.
-
..increasing jets size, alone, will not increase performance...
..not in my experience anyway....

VERY nice woodcutter

..very good post woodcutter!

we're learning while we're alive ;D
now I'm researching on how the bigger exhaust(I'm planning on installing leo vince) affects jetting and general performance

Keep me posted on that Woodcutter, im getting a Leo Vince next week so was wondering if i needed to upjet again with that?

@blue- I don't ride in the winter, but I did start it a few times this winter since I did the winterizing kinda late in the season. It started up just fine, probably a little tougher than normal, but that was expected with the cooler climate. Maybe 15-30 seconds at most of adjusting throttle while cranking it over. Although, this winter wasn't a very cold one as I'm sure you know, the brutal snowstorms and overbearing cold missed us somehow. If we had some of the -5 degree days like in previous winters I'm guessing cold starts would've been a different story. With all that said, I have been having a harder time starting it since the installation of my 72cc kit and several other mods, but I suspect that is just a carb tuning issue which I hope to have resolved shortly.
How were the cold starts for you this winter, in GR correct?

Any exhaust that breaths better than OEM will need bigger jets. Depending on the degree of improvement you may not need to increase the pilot jet. Some pipes work better than others. To be on the safe side I would get a few up jets with the pipe.

I got more jets than the Airforce in my garage. Checked on the LeoVince website for info and according to that they say i dont need to uojet ??? Says all LeoVince products are "plug and play" and will run on stock set-up and jets, no other mods are needed ???
I know on 2-strokes you need to upjet but is 4t the same? Why would LeoVince say you dont need to rejet?
May need to start a topic and ask what others did when they fitted a Leo to their A50.
-
it just said to replace clutch springs but I think it's only for 2stroke to make it resonant.
nothing about jetting, but it would be wise to re-jet after fitting L scoot on.
there's no cat in the exhaust and not much back pressure/silencing as oem so it could lean out mixture through exhaust valve
-
I plan on ordering a few new plugs to check it anyway. Should be fitting it wkend after next.

My ONLY assumption is they are more show than go on a 4t

Yeah i dont expect much or any extra performance from it, if i get any then its a bonus. I need a new zaust anyway cos my stock one is a rusty mess. Luckily The Rookie who's re-restricting is selling me his so its a little cheaper than me buying new. Im mainly buying it since its stainless and wont just rust up like my stock one, plus they do sound nicer too.
I'll let you know if i feel the performance improves or not once i try it out. Dont expect it will tho.
-
me too. mine is rusted, especialy pipe from cylinder head to muffler. but, I drive it almost all year so it's expected.
stainless leo vince could make a big difference concerning rusting issues

Yup im the same, the only time i dont ride it is if the roads are covered in snow. :D
I only put my current exaust on last yr, aboutv10,000km ago, its not blown yet but it ruins the whole look of my scoot. My stand is the same so i plan to clean that up and spray it soon.

NICE!
