Title: engine shutting off!!!!!
Post by adrinachrome on 07/19/12 at 20:32:04

i have a problem that im not sure how to fix. before i start i will explain something. After having the bike for about 5 months now i was ready to make some noise. So, i purchased a jardine muffler. After installing it i was shocked at how loud it was but also didn't like all the back firing. so i took the carb out, cleaned it, and put everything back together. i also did the white spacer mod. as it is now it has the stock jets. now heres the problem. when the bike is at idle its fine but when i hit the throttle hard it acts like it wants to die when the rpm's come back down. it doesn't die but acts like it. every time i get above 70 mph and hit an exit ramp things start to happen. after going above 70 mph and then slowing down to lets say 30 the engine shuts off. after wondering what was wrong i gave the bike a good look over and found that the vacuum line hose had a crack in it. so i replaced it but i still have these problems. thanks for your time.

You need to go thru the jetting process... highly recommend serowbots.

Whenever you make a modification, and it results in something you don't like, go back and undo it. If that corrects the new problem, you know that modification didn't do what you wanted. That's the reason for doing one thing at a time, and keeping notes.

White spacer mod. Did you shave it, remove it? It's designed to keep a bit of gas saved so it won't die after coming off hard throttle. At least that's what I have come to understand from reading around here. I'd remove the spacer and add 3/4 of its original thickness back with washers. Maybe go tomthe marketplace and get one of lancers jet sets and go up a size in main and pilot jets. It also comes with the washers for the white spacer mod.there are also several jet tuning how to threads here.

Edit: lol looks like I was too slowin the reply lol

charon...... i tried that approach. after the shut off i put the stock muffler back on and the problem still occurred. as far as the white spacer mod i just shaved the spacer in half. do any of you think it has to do with the jets or the fuel mixture screw? i ordered a jet set and hoping to try out the 150 main and 155 pilot....... time will tell. thanks for the help.

O.K. 2 things here, 1 you said you took the carb apart to clean it, did you make absolutely sure the TEV was spotless not even a fingerprint on it? If you didn't get this that clean it can stick causing you a lot of headaches. 2nd with the Jardine slip-on I can pretty much guarantee you that your gonna need to re-jet as it's a flow through muffler with very little restriction. The white spacer mod is only needed if you are running lean on your mid range throttle positions, it does not cure backfire issues.

Id put the muffler back on & prove its just jetting, if it doesnt run like it did before the swap, you fixed it broke,.

The Jardine will make you lean... but, since the problem is still happening with the stock muffler back on,... you have boogered something in the carb...
Don't try to rejet to correct this... It'll only confuse the issue...
Undo, the carb mods, and make sure everything in the carb is clean and functional...
You need to do a Do-over... Once you have the bike running like it did before, by only correcting changes you made,... you can proceed...

Too often,.. people try to correct one problem by adjusting another... this gets you a one-way ticket into tuning hell...

hahahahaha......well i understand what people say about the headaches now. so, took the carb back out looked over everything. everything seems to be in order and recleaned it. checked all the hoses and they all seem good. it seems we have an update in more problems. after doing it all again, ive lost count now, the bike barely wants to start. before, it only wanted to die at idle when i hit the throttle hard now it wants to die when i give it about 1/8 throttle. the bike acts like its not getting fuel, it will run for about 10 or so seconds then slowing die. i dont understand this because i didnt do anything different then what ive done before. could it be a faulty petcock? SWEET MOTHER OF GOD( it slams its head against the wall)

..... and the dawn of comprehension begins to break at last, dispelling the swirling fogs and murky darkness where the evil plotting vac sucker prefers to lurk, slowly sucking the sanity out of the minds of its helpless victims.

The black mood of despair begins to lift as spirits are encouraged by the dawning of comprehension.
There is hope at last .....

SKREEEE !!!! SKREEEEE !!!! Hark! Up there, in the sky above us, lit by the first rays of the breaking dawn, it is the soaring form of the mighty Raptor !!!

The Raptor's marvelous bird of prey eyes penetrate the murky fog and he quickly spots the slinking form of the evil vac sucker as the vac sucker hurries to hide behind yet another murky misleading symptom.

It does no good, for the Raptor begins his never-failing stoop, dropping down from the heavens to snatch off the evil vac sucker and fling him onto the scrap heap.

;D ;D ;D

Since the jardine will make it run lean what kind of slip on muffler do you advise.

Put it on prime, let the bowl have time to fill up. Petcock to Run, drain bowl, was it full?
If so, Put it on Prime & start it up. If it wants to die when you give it gas, Id think th slide isnt Perfectly Clean & DRY.
If you fill the bowl up,but forget to put the gas line on the carb, itll run a block just on the bowl,, & OHH Please dont ask me how I know,,

It's already lean from the factory unless your in high altitude areas in stock form. On Carb'd motorcycles any change in allowing the engine to breath differently, you are going to have to do some carb tuning. The same applies to cars as well but they aren't as sensitive to the changes that small displacement engines are.

Make sure there are no fingerprints on the slide, take care with the diaphragm & align it correctly, check the jets for junk, paper towel the inside of the carb where the slide goes & make sure no paper stays in there, paper towel the slide, no fingers on it,
See how that goes,, if it still runs like crap, put the original exhaust back on. If it still runs like crap, walk away for a while. Think about what youve done in the carb, then, go back in,slowly, meticulously & scientifically, study everything in it, check float level if you messed with it,

Well the bike is running now. I noticed that the white spacer wasn't exactly flat. It had one side that was just a little higher than the other. I shaved it down a little more and made sure there were no finger prints on anything by using latex gloves. After all that it still wanted to die so out of curiousty I adjusted the rpm screw. After that it ran just fine however I haven't took it out on the interstate yet. I really appreciate all the help guys. Thank you all so much.
