Perpetual: Vino Washer Removal Thread [Archive] - Provoscooter.com

I have a 2002 Vino with no modifications (it's as it was when I got it from the factory).

It has VERY slow accelleration, and a top speed of just under 30MPH.

If I go through the steps to remove the exhaust-restricting washer, how much of an accelleration/top speed increase should I see?

How much more accelleration/power would I see if I spent the time/money to go 'stage 1'?

you know it doesn't say... I thought erich's (provo) derestriction instructions said but they only say for the "stage" installs...

If your pushing a big 30... restricted... I would imagine that "derestricted" you should be closer to the stock 42mph of a zuma as it comes derestricted...

It only makes since that would be the case... however I'm not sure of exact speeds...

It's can't hurt... it's free speed...

Thanks for the info.

Is the de-restriction pretty easy to do? To be honest, I've never done any work on a 2-wheeled vehicle, other than changing the oil.

wow... you'll be suprised with your 2 stroke... the only oil your gonna be "changing" is the gear oil...

Just fill and go! Got to love 2 strokes...

Basically the hardest part is drilling out the washer in the exhaust... I'd use a cutting tool on a dremmel...

Be careful and go slow... There are 3 tac welds on the washer in the exhaust that need to be "ground" off... This is right inside the exhaust where it connects to the cylinder.

as well the washer in the tranny, it's simple, just need the correct size tools... I think the vino bolts are the same, the tranny bolts are 5mm hex, 17mm on the variator bolt... then simply remove the washer and your good to go... there are better instructions

exhaust (http://www.provoscooter.com/shop/howtoex.php)

variator (http://www.provoscooter.com/shop/howtovar.php)

all in all I think your gonna be happy with it once you have done these 2 mods!

Will I get a noticeable difference without removing the variator? I may do that eventually, but I'm only interested in removing the exhaust restriction right now.

Thanks for the help! :)

Also, I've heard of problems after the variator mod, due to what it says at the bottom of this picture:

im not sure what you mean by the picture???? I would DEFINATLY remove the vari washer as well..... in that pic, it looks like the belt is half way down the rear pully?? that is why you see the sag in the belt..... Removing the washer in the vari will only allow the belt to ride higher on the front, not lower.....

XPS1210

02-04-2005, 03:31 PM

that is how the belt looks before the engine is "turned" tightening up the belt... Your not doing anything but allowing the variator to spin the belt ot the top of the variator now... Stock they limit it with a washer to keep it from riding the whole variator... causing the 30 mph limit.. take the washer out..... That's probably the biggest thing that causes your speed to improve... the exhaust helps with acceleration not over all speed... (well maybe a little but not as much as the washer)...

If you remember in one of the other pics.. it showed compressing the rear pulley to allow the belt to "get deep" into the pulley... this is to allow enough room to get the belt on the front shaft..

You can't possibly fit the belt on with it all the way up the rear pulley it's not long enough... that is why with the belt "into the rear" pulleys a little ways, and just sitting on the front shaft, it droops... once you install the rest of the variator, and spin the pulleys a few spins, it'll tightent he belt up and it will NOT hang....

that is a bad pic for someone who has never done the install before... It looks to make the belt longer... but it doesn't... that's not a completed pic...

DO THE VARIATOR MOD... it WILL NOT HURT THE BELT OR TRANNY.... just a bad pic... this is how a completed one looks... it will not hurt the belt like your thinking...http://www.provoscooter.com/vbull/article.php?do=viewattachment&attachmentid=30

I regretted when i only did the exhaust derestriction, in order to get the Vino to run worth a damn, you got to remove both the mulitvar washer and the exhaust washer. But you need to rejet regardless if you remove the exhaust washer.

I think it depends on the altitude where you live whether you need to re-jet or not. Here in Colorado there is no need to re-jet after de-restricting....I think it is about the same elevation as where Erich is in Utah, hence no instructions about re-jetting.

King Vino

02-04-2005, 05:52 PM

I've found regardless of altitude you need to rejet.

other than chocolate plug... if it's white or grey you'd need to upjet... black and you'd need to go smaller...

Hi Frag Monger,

Just jumping in with my 2 cents :)

I ride a Vino too and after derestriction mine did 43 mph on level ground. Understand that your Vino was actually designed to run without the exhaust and variator restrictors in place, and those restrictors were only added to meet "moped" restrictions in states that have them, so removing those restrictions will not hurt a thing.

I've since done the stage one upgrade and I love it. With my present tuning I can cruise with the speedometer needle in the middle of the turn signal indicator! ;)

I have a 2002 Vino with no modifications (it's as it was when I got it from the factory).

It has VERY slow accelleration, and a top speed of just under 30MPH.

If I go through the steps to remove the exhaust-restricting washer, how much of an accelleration/top speed increase should I see?

How much more accelleration/power would I see if I spent the time/money to go 'stage 1'?

Rejet? (Scuse a scooter noob)

XPS1210

02-05-2005, 04:14 PM

put a larger MAIN JET into the carb. when increasing fuel and air flow you need to increase the amount of fuel into the carb/engine...

upjetting or rejetting is litterally installing a larger main jet...

I ground out the restricter in the exhaust don't use the hammer and chisel method you will bend things. Have at least 3 grinding wheels to work with. My scooter as with every other would do 29 with a tail wind. After the exhaust mod I did an accidental wheelie right out of the garage scared the $&!! out of me. I did not re-jet and it ran fine in warm weather at about 41. I have noticed this winter a major hesitation stumble what ever on intial start and the speed down to about 34 max. Will re-jetting to 72.5 today and doing the washer removal we'll see what happens. o_o

I'd like to ask you other vino-wners, any recommendations as to whether or not to wait until after the break-in period of the engine to 'derestrict' the exhaust?

Those of you who did it before 500/600 miles, did it still run/start as smoothly?

any expert opinions would be appreciated.

sooznd

Hey there Spanky-
I de-restricted my Vino at around 300 miles when I changed my tranny oil & spark plug. The difference in pickup was amazing--it was so zippy--I almost ran into a tree in my yard because of the sudden peppiness.

I wouldn't wait until 500 miles and I think others have gotten theirs de-restricted by the dealer upon purchase, so there's no harm to the scooter, although you should probably not go full throttle the first 100 miles or whatever the manual tells you---although the temptation is almost too much :yippy:

The Vino was designed to run without restrictions--the exhaust & variator restrictions are for the US market to accomodate those states with moped laws

Enjoy

Spanky

02-09-2005, 05:01 PM

thanks, sooznd.

My dealership told me they could do it for me, but i decided to wait until i had it a little time behind the bars before i opened it up a little. 50 miles in one week...i'm getting closer, and so are the cars when I'm doing 30 in a 35. Just a little overly cautious with my new baby, you know. Thanks for the needed reinforcement of "GO GET IT DONE!!"

Spanky - if you are new to scootering like I was, it is nice to get a feel for the machine & how it handles, how to ride in traffic- plus you will really appreciate the power after the de-restriction. You can pull out from a line of cars like a bat outta hell :man:

I haven't done any of the performance upgrades to my scooter that many Vino owners on this forum have done & probably will not--she performs well enough for the riding I do plus I am not one who is enamored with tinkering --I want it to go right the first time. Adding accessories and customizing the look is my thing.

Spanky

02-10-2005, 12:01 AM

Sooznd, That's exactly how i felt. I'm feeling really solid on it now, cornering and overall handling very well, and navigating in the worst of the business district lunch-time traffic without a hitch. I'm not interested in muscling up my Vino, either, but since i am a bit (30lbs) over Yamaha's recommended weight limit of 165lbs, i think the delimiting should serve me quite well, indeed. and because of that weight deal, it might allow me to stay off the throttle a little during it's break in period.

On the subject of customizing, I'm having a bit of a time locating those Japanese style blinkers (i would LOVE those) and the cup holder. Any hints?

I just finished the free mods plus rejetting.

I weigh 257 and 20-25 before the mods.

Now took a short ride tonight 31 degrees got 37 out it before my eyes started watering.

Another testament to the derestricting! I'm anxious as hell to get it done now and i should have it over to the dealership on thursday (just might as well have THEM do it so I'm sure it's done right) but one thing is bothering me: When i asked them if their quoted price of 40 bucks included rejetting, they told me "rejetting, not necessary". I live in northern california, near berkeley & SF (though on the warmer side of the bay), so I'm not sure if my altitude makes a difference, but i guess i'll find out when i get it back from them if i do in fact need the rejetting.Any input?

Riding in the rain today was not much fun, and that 29mph i was hitting just not doing it for me (or the jerks on the 35mph speed limit road i was on).

Ride the scooter a while and shut it down, wait a few minutes, maybe upwards of ten to fifteen, and try to start it over, good chance that it will stall. Unrestricted Jp Vinos came stock from YMC-Nippon with a 67.5 jet. Sadly the 67.5 is not something you can find in the states anymore, so a 68 jet for a derestricted Vino will work fine. The 64 jet that comes on YMC-US Vinos is not to spec with the OEM build from Nihon. (Nippon, Nihon is the proper way of saying Japan)

The preceding jet info was courtesy of my friends who run Simon2001 of Osaka, Nippon. (Someday I hope we will be carrying their line of products here at Provoscooter.com)

ya same here on my vento rode with and aftermarket pipe for miles and even had a master mechanic check my plugs to be sure it was the same thought that i had my plugs were perfect always.

cant drive 55

02-15-2005, 05:06 PM

I live near shayandaman and smokin, they didn't have to rejet but when I installed my Stage 1 I had to rejet my carb up to a 76. I did a plug test just to make sure that it needed to be rejetted and it was running a little on the lean side. I guess in the end you just have to do a plug test to see if you need to rejet or not.

King Vino

02-15-2005, 06:09 PM

From what I have read on other boards, you do not need to re-jet if all you are doing are the de-restrictions. If you add a new pipe, you need to rejet, but not with de-restriction only. If the Vino was built to run without restrictions, wouldn't they have put a different jet on it to begin with? I have over 500 miles on mine since de-restricitn & no issues stalling or otherwise.

Yeah Matt told me that too, at the YMC, I worked at for a while last year, as did Steve at the Yamaha dealer near my house, as well as everyone on the Yahoo message group, but that was bullocks, I did need to rejet, I did have issues with the stalling, so I emailed Yamaha, and they were not sure, finally, I talked with Simon2001 which deals with factory Yamahas from Japan, and this preceding info I posted came straight fro mthem. I'm 303' ASL and despite so called pros telling me I don't need to rejet, I had to do it. THe factory specs for the Vino calls for a 67.5 (68) jet, and sicne I did it no more issues.

It's almost kind of funny coming from an ex-cop, that I'm an admin on a scooter performance board, yet I'm probably the only person on here that not only has nor set up my Vino for performance, but rather spent all my time, money and effort to de*******ize my Vino by restoring it to the OEM, Japanese stands, by de-North Americanizing it. (Almost sounds anarchistic!)

The field elevation here is 1,200' MSL. My scoot runs well, but I'm sure it needs rejetted with my Next R installed. I'm going to order 2 or 3 jets from Erich and get it set up right when the weather warms.

It was 52 degrees when I woke up this morning, but a cold front came though and it's snowing now.

I am soooo ready for winter to be over!
