- XS650 , wont start.kicks back, backfires, sometimes runs ups for two seconds but stops yimmediately .Rebuild Engine Top End (Checked Cam to Crankshat. It`s correct fitted). Carbs, cleaned and rebuild wirh new needles, jet`s and seal`s . Blue Boyer installed. Open Port`s.Timing set to the advance Mark.
I have an XS650 cafe, had several of them way back then, I believe 5 or 6 in total. This one is staying now :) Some of them wrecked my ankle and feet more than once. I´m 60 now and rather skinny, I don´t risk kicking no more, just scared XD. If the battery is dead, I get the booster. Riding it is still making me feel 20 again.
Don't throttle while ur kick starting....
Don’t give the throttle while kicking as it will kick back every time then.
My 1971 XS650 was starting hard. Still has the points and mechanical advance. Found the springs had weakened on the advance and not returning timing to start mode. Worth checking. Replacement springs readily available.
Good call
Yo tuve una xs 650 y nunca me costó trabajo encenderla con el encendido auxiliar y nunca me pateó el pedal. Muy buena motocicleta de lo mejor que Yamaha pudo inventar. Saludos desde cdmx
I definitely think your timing is too far advanced. If it's an older bike with points, start there and make sure it's not stuck at full mechanical advance. The electric start on mine doesn't work, and when I start it cold on a cold day, I first prime it by kicking it through a few times with the ignition off, turn the key, and then while straddling the bike, hop up and come down in one fluid motion. Never been bit by backfire while using this method. Edit: Just realized this video is two years old lol. Not sure why it got recommended to me now. Hope you got it to work!
my 650 got so bad with weak advance springs kicking it would result in the carbs getting blown off the engine the fix is relube the internal shaft an get new advance springs
Is there a decompressor in this bike ?
Bike Is running. Problem was the Boyer Ignition. The Timing Mark didnt fit for a working setting. I set the white dot on the Rotor with the stator hole aligned aprox. 15mm lefthand of the left marking on the crankshaft and it fired up(very early).
Congrats! Love the meaty exhaust note of this engine. I have a street tracker waiting for jetting of its aftermarket bigger Mikuni's.
bring it to TDC first before you kick it, if your carb has a throttle pump, pump it a couple of times to give it some petrol in the manifold, full choke and twist the throttle to 3/4th to Wide Open Throttle.
then kick it hard, it will start for sure.
Don't twist the throttle while you kick it, it will kickback for sure and it will never start on a cold engine.
once the engine ticks though keep your foot off the kickstart because when the engine dies it will kickback really hard, when your foot is on the kickstart when the engine dies.
How can you tell if it's at TDC?
Part of the problem is the way you're kicking it. You're immediately bringing your foot back up. You should kick and stay at the bottom of the stroke for a sec. When you bring your foot back up so quickly you're just asking for the kickback.
Right but if you hold it for too long you get kick back anyway I just kick it and Bring my leg back up quickly and don’t straight leg it either probably the best way.
Thank God for the push start
It makes me cringe when he locks out his knee at the bottom. If it kicksback now the leg will bend in the opposite direction 🤢
Thats true on my shovel head and then evo. And i got the scars from the kicker painfull
That's why I only kick a bike from sitting on it so I prevent my leg from locking out. But my bikes are generally around 350cc so they're easier to kick over. Although I will say. I had an xr80r in 2001 that kicked back and it hurt like a mofo
Sounds like timing 180 degrees out ... try swapping leads from left to right and give another go. Definitely do NOT straighten your knee or it may end up going backwards.
Best of luck
Is worst than having a fight with the wife lol
Either timing is off or you may have a bad points/condenser combo. I had to replace points and condenser on my 1979 XT500 because they were worn out. After replacing, it would backfire, run like crap and the kicker would take my foot off. I replaced again and it was fine then.
great bike
Why do all you people try to start these bikes by standing off to the side??? When I was 15 I had a 650 triumph a 1966 it was bored out to an 800 I would straddle the bike walk that Kickstart till I know I was in the compression stroke jump up bring all my weight down on my right foot and end up straddled on the bike ready to go. What's with all the standing off to the side to kick it and then you kick it with your left foot you're not going to have all your body weight on it. And if you're afraid of it kicking back then set the timing on it and adjust your carburetor. I was 16 when I rebuilt my triumph.
I find push starting a stubborn bike easier than kickstarting one.
F me dude, you haven't turned 50 yet huh? Someone should either teach him how to kick-start, or tell this guy there is wee button on the righthand side that activates the starter motor.
@@malcolmcarter2675 so kicking a bike repeatedly get's easier when you turn 50? good to know.
@@popcatzoo The opposite fknuts, y'all can't pushstart a bike after you turn 50, there's a fkin law against it. Get a hill and roll start maybe, but learning how kick properly or a starter motor is the only way to go. Unless, unfuckinless we're talking about your momma - the only person who can suck-start a Harley and blow-start a Kenworth. Tell her the entire footy team and I will be round for our Tuesday night post practice "dentures out special" at 50c per as usual.....
reversed coils signal?
When it kicks back the engine basically ignites the wrong direction. Check timing. Your combustion is way to advance.
Check for compression and spark
start to not be affraid of your bike...
If any engine backfires it's probably the timing more than likely is not correct cuz you have an explosion going on at the top of your piston where the valves are supposed to be closed not letting any of the explosion out and if it does it needs to let it out the exhaust that means the intake valve is still open when it's exploding so you get back fire coming out of the carburetor. Could be a few gears off on the timing chain if that timing chains not put in there correctly the cam does not rotate correctly
Mine did that very same thing. Put the timing a few degrees ahead and now she stats up first kick every time!
My routine;
Turn on petcock/fuel tap
Put on jacket( takes as long to do as it takes the carbs to fill up)
Kick her over about three times
Pull choke out fully
Turn on ignition
Kick
And a few blips of the throttle
Put on gloves helmet
Sit on bike
Kickstand up
See ya!
@@airwolfie100 don't forget the parfum 😂
Had a 78 XS650 for a couple years. It was not that hard to kick start. But I practiced on my buddies 1973 Norton.
Perfect way to learn. Pump it, tdc, straddle it, lever right in front of heel then full weight on it. 3 Commandos, 4 XS650's no issues......
Hope you can find a solution which helps. Little tip, you'll find it FAR easier to start if you straddle the bike and kick it. Take a jump and let your body weight do the job. Give it a try and please post a video how it works out for you.
My oath mate, the only way to do it, have a mofoing ceeegar mate.....
Ignition, maybe inverted cables.
My 1970 BSA 441Victor started with 2 kicks. Tickle the carb first
Loosen the plugs to fire it up. Let it warm up some then tight plugs….it’ll help save yourself some unnecessary pain.
Was my first thought: timing/position camshaft-crankshaft. But it's definitely an ignition-issue. Fires too early. Normaly adjustment is "F". 15○ BTDC/1200 rpm. If you reving, mark moves to "Advanced mark". Max rpm is 3500. At this point TDC (top dead center) of the piston is unneccessary to adjust the static or dynamic firing of your Yammie. Dynamic with strobo-light is better. Then you can see moving the mark from "F" to Advancend mark. Stupid question: wiring of coils: is "left coil" for left spark plug and "right coil" for right spark plug?
Thanks for your Tips. The Problem is that Iàm not able to use a Strope-Ligt, because the engine is not running longer than 2 seconds. I`ve the Blue Boyer installed, which ignites every 360 degrees(means both Spakrplugs getting firred up). Thats what I thought, but I Will try to switch the wiring from left to right to see if somethings changes.
' yes the Boyer should be wasted spark firing . is the blue box just an electronic ignition to use with the original mechanical advance ? if so I would recommend the fully electronic Boyer
I’m having the same issue with my 72 cl100. Good luck. Post what comes of it if you can.
Set the idle a little bit high...and don't give throttle....
Second....kick when the piston reaches the middle position
Set your timing and valves
How it feels to get kicked back, this is why I don't mess with my grandpa's bike.
Bro Hold the Kicker down when you kick it...
You're doing it wrong, you twist your throttle to full, it will richen the mixture and flooded the engine
If it kicks back so many times why do you keep doing? Something's fucked up
timing to advanced
How to solve kick back problem
Its All sparepart good condition
(Check Timing Ignition)
15 degrees before TDC
(top death center)
at low RPM and 25 degrees towards 4000 RPM and so on with an increase of 2 degrees for every 1000 RPM increase until the maximum key is at 35 degrees TDC when at limit RPM
how did you fixed it. plz same as mine
The marking for adjustment of my boyerI-Ignition-Plate wasnt coorect- Adjusted the Ignition to motr advanced and it runs.
@@alexisonwater3100 tried it today and it still kicking back,, but it runs. 😁
@@webtech4759 Thats sounds good. Use a strobelight for fine adjustment and everything will be fine.
you'll learn one day grasshopper
Your advance mechanism needs attention. Either weak springs o seized.
Have the same bike won't start what was the issue?
It was an Ignition Timingproblem with my digital blue Boyer Ignition. I will make an extra Video about this issue.
@@alexisonwater3100 thx Alex
Brooo,,, purrr teuing lewih saeutik eta stelan na
Never try it with your toe mate, straddle the pig, put the rubber in front of the heel an throw you entire weight into it. Built 4 XS's, never had one throw me off - even when I accidentally reversed the points hook up on one (kin beaut back fires on that beast using raw ether until I realised what was wrong).
Kickback 0:23
Spray some ether in it
Timing is off
Sounds like valves are out of adjustment.
It was the ignitiontiming. 😉
Yo dont need to put your whole wait then jump to turn it on when you need to start it get ready and immediately put your whole wight on it
Maybe your timing is out 180 degrees
Kolere ding
Timings out. It shouldn’t kick back every time it fires.
Time the damn thing
Coil
Wires must be switched then it will run
No, it was the timing of they boyer. The markings of the Statorplate is wrong.
check your timing
I can’t wait till someone invents some type of electrical starting thingy that could be used on Motobikes
Misststück von Motorrad
F**k the bike he says as he heads for the kettle!
screw that I would have taken a hammer to that motor a long time ago
Leave the throttle alone.
Не! Ну нафиг! Стартер наше всё!
god bless electronic ignition .....
Ok...Like an old Harley....it's a show bike.
It has big compresion becuz of too many power for 1 cylinder
Too advanced
you can't kick, no wonder it won't start
)))lol
😅
I can see that you're not very good a kicking a bike over 😆
The damn thing is illegal anyway. No silencer . These machines are a menace to society
Sorry, but its all legal. The Exhaust is Stock and the open pods are legal and written by german TÜV in the Bikepapers. So be angry on someone else and have fun while hating.
Use battery to start
I have one, they are little Bastads!
first you need to learn how to kick start a bike, you're doing it all wrong, then you should be looking at the ignition timing as it's all to fuckery
Pull It down into the bathroom 🤮🤮🤮
5 words .... Honda, Fuel Injection, Electric Start.
= Boring .
Death trap,i will never ride one of those
he is just terrible at kick starting a bike
Frig this was painful to watch. Buy a dirt bike and learn how to start it. By the way your kicking this thing make sure it’s a 50cc. Fml
U CANT EVEN START A DAMN BIKE. ! 🙄😑
