main jet NOW #88 , but still slow ?

[Jasonic]

I have not been here in a while and not riding as much as I think I should, please forgive me.

Now , as you see in my pic I have the 2001 Elite SR, mainly stock still and finally I pulled up my old main jet #78 and replaced it with the #88 , something i been lazy about doing , but I finally did it. Stock Air BOX has those 2 air-slots right, cut the 2nd one open for added air, But I am only going 35-36mph, I stop and adjust the carb some , I drop to 31mph, then tune it back, ony 36mph. With my new #88 jet I thought I would be hitting 40mph? I took the AIR BOX cover off and can see the sticky stock foam filter, ran it like that - too much air only 26mph, put the cover back on - back at 36mph. Should I plug my 2nd air-slot hole again and see if i go faster(using 1 air-slot)? That was the only thing i didnt do. last year I cut that 2nd slot open without adding the bigger jet and had to plug it to get my normal speed(36mph).

Yeah I know spend $40 on the varitator with 9g rollers , I just haven't had time yet. I just want to know if i should be expecting more speed with main jet 88 + more air. Is that bigger jet mod needed only if i GOT the vari+rollers.

Someone let me know. Thanks.

Unless the motor fell flat on it's face, why would you think changing the main jet would change anything? I would suspect that you are too rich. Do a plug chop and see what the mixture actually is.

Greetings:

If your filter element is "sticky", start by replacing it. If as I suspect it's 11 years old, the next thing it'll do is begin to crumble and shower your reeds with debris..
Anyway, it should be "springy", not "sticky".

A compression check is the next quick and easy step. You can verify the plug color. My guess is that it'll be a lot darker than the ideal "cardboard" color.

If compression is good and it's still under 40 after that, consider that you may have "jumped over" the ideal jet size when you went from 78 to 88 - a hair lean to Too Rich. Perhaps an 85 or 82 will remedy this

My bone-srock '01 went 42 on GPS - AFTER -I replaced the filter element.
49 with variator, 90/90 tire and 9:1 gears.

[konaking]

Try a 82 jet or 84. What exaclty did you do to derestrict your bike? The variator isn't really gonna make a huge difference id say the best weights to run are the stock weights. I changed my pipe to a sym dd50 pipe that was derestricted, removed the restricor plate on the variator jetted to a 82 with modified airbox, removed the restrictor washer from the carb mani,and I hit 45 on it. That's when my bike was a 50cc. Oh and I ran stock gears. Changing the gears is kinda a waste if you plan on upgrading your engine size later on

[odinxxix]

the sr is not restricted. i have an #85 in mine. stock air box, 9:1 secondary gears, also opened the airbox. plus vari with 7.5 rollers and im close to the 49 mark

[Jasonic]

. Sorry I replied so late, I thought my email was going to notify Me.

CB900 is right, I have the SR model . So I don't have those restrictions. My friend has the 90 elite and we ran it with no filter at all max air and he was able to run 40mph, with his round after market red filter it was about same speed. He said because his jet is bigger. I read on this forum over time to use 85 or 88 main jet= better top speed, . I am replying from my phone but I like the 1st or 2nd post saying "what made Me think a bigger jet will give Me more speed". I only ran it 4 blocks with the 88jet stop and go to adjust to get a higher top speed. I am guessing I should put my old 78 jet back in. Then plug my air box so it has 1.3 holes, the 2nd hole shouldn't be fully blocked.

... Now my air filter- yes it is sticky, so sticky its drippy, crumbling apart? Hmm not really, I actually cleaned it last year to make it less sticky, but just yesterday I noticed its very sticky again. You are saying I need to get rid of stock air box and get one of those round ones?

Last week I got a 90\90 back tire since the old one looked stock from 2001 (ten years old) when I got the tire I asked for the jet88 .

Now I am wondering if I put a few bucks into the air filter will it go faster andwhat jet should I use?

I have the stock pipe l , but I don't think its restricted right, since I have the SR .

But 2005 I had an 87elite 50 , it went about 41 , I had no idea back then about modifications, I bought it for 80$ with 12pack of beer from a guy. Was lucky. But in 2005 my best friends took my intake off, ported and polished it, then got a long drill stuck it in the pipe to make it breath better , after that I was doing wheelies any time unlike before when the belt and motor had to be cold to do a wheelie.

But since 2010 with my 01 elite it slower then my elite I used to have but the power is there, and I can wheelie anytime, and with slight hills I can get 40 and hold but. So since I know I got the power I want to use it for a higher top speed. Since my SR is SR, I am not sure what to do, air filter 85 jet - And vari got someone 49mph? I will be happy with 46mph . Haha.

What should I do guys? Thanks. I will check faster online and post some pics even though it all looks stock and I raped my air box 2nd hole.

Jason

Ps-i rode from Los Angeles to san diego- by car 2hours , my 50cc 4hour 20mins . Average 36mph. .

[Jasonic]

.. This is for wheelman, you said you had 01 stock and changing filter\filament got you to 42mph? Did you use the stock air box and different spongy filament, or you got the aM round type? And was your 01 elite SR with main jet 78?

Haha I am writing so much and through my phone, my girlfriend thinks I am cheating on her, and she wants Me to sell my scooter, never, here in LA I found 2 Honda elite 86 spree? And 94 elite in some korean market, both at price of $150 ! Not working but what I am interested in is the 94 because the license plate is Hawaii !! So I am betting it has been modded before since its in californina now. Not sure if I am ready to handle 2 scoots now, I would need to buy a truck. 1 scoot at a time yeah.

Greetings:

My 2001 hadn't even had so much as fuel added. I brought it home and rode it one day without touching a thing. The air filter crumbled and a bit of the filter foam jammed in the reeds and stalled it. It self-cleared and re-started and I rode home to put it away until I could get the new foam element. Once replaced, I ran a GPS run or 2 for baseline speed and got 42 MPH. All stock.

[fastplastic]

i would be checking compression and for a small vac leak....

[Jasonic]

ok , I will check compression and look at the plug . But I am sure there is no hose leak or anything else looking bad . What my concern is HOW the stock FOAM/filament/filter thingy gets STICKY with greasy oil , when i first got it there was sandy dirt over half of it because the dude I got it from only used it on dirt off road because he had horses, anyways I cleaned it and it was still oil/sticky even after i added warm soapy dish soap water to clean it.

If Wheelman said he went from all stock to 42 by changing the foam filter , then i should also right? Not sure if i can get my money back on the #88 Jet but i will trade it for an 85, but use my 78.

I will buy an A.M. air filter , check for leaks, check compression , and check for girls at the beach (San Diego California) (right now I am in LA near Santa Monica but never any hot girls around) .

So by Saturday night I should check all those things and post here again. With a picture or two.

42 hmmm with the new filter you say, hmmm I want to try that. I kinda like the look of my stock air box because its black, i will try to find something black.

thanks everyone, its 11pm now, I will be up at 7am swapping my #78jet back in while checking for leaks. Ohh is it NORMAL for the 2stroke oil to leak down into the CARB ? its supposed to right? That is how it mixes in ? I think maybe too much 2strk oil is there? no no, but when i pull the carb/air box off there is lots of oil there. That is normal i thought yeah?

Thanks everyone.

Jasonic Axt-ed:

What my concern is HOW the stock FOAM/filament/filter thingy gets STICKY with greasy oil ,

It is in the nature of hydrocarbon polymers to break down over time. They are trying to revert to the primordial Ooze from whence they came. The foam might be 11 or 12 years old, exposed to solvent (gas and oil) Ozone and whatever and it just Does that. Same reason tires get cracks, and old polyethylene gets brittle. Replace with a new Honda element or try to re-jet with a UNI filter.

[Jasonic]

Broke my coil head above the spark plug! *! That's never happen before. Dang dang, can we curse here? Haha , I took pics, and filter stock if crumbling on top side but not back, but its all thick and sticky, went to check spark and the coil top broke. Grrr

[Jasonic]

Bad friday ... I just did this about 1pm .... and now adding the pics from my phone

my blackberry sucks with pictures , but i think you see my new main problem, broken coil to spark, ... I have a 2nd scooter('94 elite) sitting at home so i will swap it until i find something new.

Rain, broken coil to plug, and i cant return exchange my M.jet , also my gf is mad i ate her ice cream.

Give me a break!
