Modern Vespa

I routinely have people in my shop and show them how to do that.

Isn't that what the NSM forum is used for generally? 8)

I think thats the intention but general questions are often hijacked for humorous or commented on by the one thing this forums not short of is opinions, and they range from the
"just bolt it on,or ride it like you stole it"..........to excellent "not anecdotal" brilliant knowledgeable advice,a technical section would contain factual not spurious opinion based on known information.

some things are personal choice
but we would all agree " fitting the cotter pin before riding"is sound
unequivocal advice,

I posted several questions with a completely bewildering
myriad of opinions and contradictions, so its impossible to make a valued judgment ,a tech section would remove the..........................

"i just put a tortelly 199 kit on with red stickers ,took me dremel to the ports ,pre mix pure goat oil ,added 75lbs of chrome bits ,up jetted with plumbing fittings ,put a ziminelly pipe on, its the loudest pipe in the world,set me squish with vintage 60s string ,cotter pins are for wimps , it did 95mph before the wheels fell off and it seized "why"

Welcome to MV George.

Tortellini anyone?

lol

On a serious note trying to not only pick the clever from the crass ,and then calculate the agenda of the person thats giving the advice, makes it doubly difficult ,perfect example my first xs650 was unfortunate to fall into the hands of an idiot that bolted on shiny crap, with no consideration for the impact to other systems ,cheap pods , jets,pipes etc this ain't pick and mix ,

piaggio v man in shed with adjustable ...........................on the xs Carb kits standard,standard airbox air filter,carb sync nothing clever the bike then ran like a dream!................................................

a real simple 2 stroke question premix v auto

1:always premix new a man that had a friend that overheard a man in the pub ,saying his bike seized with auto..

2:Never had or heard of an auto failing and at higher rev,s the pump increases the oil mix

3:premix always, i can get a more accurate measurement with my grannys milk jug than any oil pump can

4: Its not that simple, its dependant on altitude and orientation of the bike
viscosity ,shelf life and manufacturer ...................

george befuddled

Whats your port timings on your 2015 px george?

Sorry mate i honestly don't know ,not had the bike apart yet, still under warranty ..................but i know a chap that measured the inlet port size comparison for me on a early standard px 125 and a 2012 px125 , i will ask if he can measure both port timings and i will message you
george

your right mate

It's a bit of a pipe dream, unfortunately. We have a wiki for dry knowledge to just be typed out. I don't think NSMers use it much at all. But it's there. But this forum is 95% tech discussion. If you create another forum "dedicated to 'only REAL tech knowledge'" then most of the technical questions are going to move there, and with them most of the oddball answers we all have to give. It might start off as you intend, but someone is going to venture an opinion or hearsay at some point and then others are going to rebut their opinion and then... well, it's NSM 2.0.

We can start a new thread to discuss more, if you'd like - I think poor scooterrorist's thread has been hijacked enough (by my own - albeit well intentioned - posts, among others)

Hi mate ,don't know if one can workout duration of the transfer port using the dimensions of the inlet port?

this is off the uk forum i posted an inlet size question and these are the responses scroll down for pictures hope its useful

http://vespa.proboards.com/thread/5288/confirm-smaller-inlet-port-transfer

and as you seem to know all about this

Question:how does the size and duration of the inlet port /transfer port impact on the exhaust port, does more fuel mix mean longer exhaust(wave)
larger for the charge to come back

thanks for the help keen to learn

george

hijacked from the start

some people have understood the simple question I asked and given some great info,including linking there build thread for more of an understanding how they built there engine and why

would like to carry on the thread with these few people if i get chance to give them any time for a reply

Hi sorry was posting a link for scooterrorist, Sorry but i dont think thats what actually happens .The xs650 had such a place
http://www.xs650.com/tech.php
purely for technical mechanical stuff ,i understand the forums supposed to be fun and informative but the nature of vespa ,with stickers lights and mirrors bolt on chrome mod music etc is not just about the bikes there are various sub cultures all within the community,to be honest i,m not sure when i get a response if its from someone thats revving a bike to destruction or gleefully counting the times they've broken down ......or a technical genius from piaggio..............or someone just taking the piss.........

I have realised and i,m sure we all know a lot of the informed info is sent via private messages and a big thanks guys,just seems a shame that the whole forum cant benefit from unbiased factual correct information ,we have some really smart innovative people on the forum

George, for scooterrorist's sake, let's move this to this thread: Regardring idea of technical-only subforum

I think he's sufficiently clarified what information he wants to see in this thread. How much of it he will get, I can't say, but let's let it be and hope people can offer the numbers he is looking for
