Kyle Potgieter: hey man you really seem to know whats going on, please send me a mail,
email@example.com i need some help on my bike.
jason ferguson: Hey mrmax, great vid. I have 1995 triumph speed triple 900 just fitted new
engine. Starting no probs, though 3rd header pipe staying cold on tickover
until you rev it a bit. Take it out on the road and is fine for 100 yrds or
so then starts cutting out suddenly then starts again after 30 seconds or
so and then keeps doing the same. Swapped coils over same symptoms, same
cylinder, changed plugs, any ideas dude? just gonna check yer diagnostics
kevin ouwersloot: the problem is that you wreck the plate
Goingin007: And turns off
Jonathan Canales: I was like, "It runs on smoke! What the freak!"
mrmaxstorey: Thats old for a scooter battery. Start there, replace it and charge up the
mrmaxstorey: This one was full of resin too, some guys will meticulously melt it off on
low heat to try to repair it if it goes south, but I didnt have the
patience. Apparently the resin is a good idea for use on a bike that
bounces up and down so much, but it does effectively make the CDI a
replacement unit only
mrmaxstorey: Nah I dont think its your CDI, if your bike runs then it is sparking and
your cdi is fine
Francis Collier: I just bought a 97 gsxr 750... Its been sitting for 2 years. Ive changed
the plugs, oil, fuel, cleaned fuel tank and lines, new battery, and cleaned
the heck outta the carburetors. The bike will run at idle but when I ride
about a mile down the road the bike just shuts off and then about 15 to 20
mins later ill be able to start it again. Some one please help?? Thanks
ninjawy kawa: kawasaki zx11 1992 timing is 18.104.22.168
mrmaxstorey: Clogged jets, vacuum leaks, bad air filter, or disconnected components of
the intake system are the most common causes
steven bloomfield: sooooo.... where can i find a smoke injector
iwicdieify: hey man, i got a question, when i check putting the negative onto the
ignition coil and the positive into the plug doesn't read anything but the
plug is new and the wire too, it could be the ignition coil?? and also mark
4.0 when i test the ignition coil i have to replace that?? thanks
mrmaxstorey: For a healthy spark it should be fat and blue
CheshireBiker92: As my bike will only rev to 6-7k revs and thats it theres a video on my
channel about it
mrmaxstorey: Nothing about clutch plates, but I do have several engine videos up, such
as how to replace the head gasket, and how to replace timing belt
mrmaxstorey: If you can find one. Pretty much all bikes use their own CDI's. What bike
are you working on?
MrGerryking21: So how wold I find that and what's the hot wire u talk about?
mrmaxstorey: Check out the motorcycle diagnostic website I made, it will cover all kinds
of problems better than I could in a video. TheMotorcycleMedic (dot) com
frethand101: Question,I got an 82 xs400j maxim that was trouble free for 5yrs..I did a
basic tear down to clean/paint the frame,etc..Now the bike runs bad,plugs
are black..Ive spent the last month X-ing out every possible cause & I'm
down to IgnSyst..Im leaning toward the PupCoils or my CDI but my test
result has got me on the fence..According to spec,my PupCoils should read
150-170ohm..While plugged into the CDI,w/key on,I get 123ohm..Can a bad CDI
alter my Pup result or does this mean Pups are bad?..
hoochipappie: maybe you should burn it???
jose cardinal: its better 2stroke are smoke..and are 4stroke are not better to smoke..
ninjawy kawa: thnx, i will.
ninjawy kawa: thnx for ur reply , the problem is that i can't find a replacement in my
country ,can i use another bike cdi that has the same ignition timing ?
mrmaxstorey: Then yeah go for it. Solder another wire onto it and youre good to go
gksypher: Your lucky you can actually get to the circuit board on that , my one is
full of plastic resin :( . I could repair it as it is prob only a
transistor that is faulty .. but nooo cover the whole board in plastic so
you cant get to any componants :( guuurrrrrr
uday bhaskar Medida: my yamaha bike is getting off while running, my battery is ok and
carburetor also cleaned what might be the problem.............please help
mrmaxstorey: Yeah. I think its french or something
henry martin: Help, i got no spark and got a new CDI box and no start, so, i got a new
ignition coil and still won't start, any advice to solve this problem, my
bike is a 50cc Scooter chinese 4 stroke 2009,thanks.
steven bloomfield: lol
mrmaxstorey: Probably not
giordanobill2012: I have a 84 GPS 900 ninja its getting intermittent spark every once in a
while should that be my CD box or my coils
mrmaxstorey: could be
Johnny Wieler: Ok i got a 2007 suzuki ltr wen its cold it starts good and runs for a
lil...wen its warmed up it don't wanna start jus turn over??
mrmaxstorey: They should be on different circuits. Maybe your cdi is on the way out, and
the rebuilt one is faulty?
spy111kill: Hey max! I have question. Is there any way to fix my CDI boxes connector
wires? Why I'm asking this is I have an ATV and the CDI boxes connector
wires are off. Is there any way to fix them?
Rawsome Wayne: Hi Max.i have a 1982 Suzuki GSX 400f ,it starts up fine runs well ,but as
soon as it gets hot it just cuts out,i have been told its probably the CDI
unit,,what do you think ???
dustin hepp: I have a yz 250,does it need to have a certain amount of spark cuz it only
has a lil spark.any suggestions..plz thank you
Repdan1: ok so the lights went on today for a few minutes so its not my cdi in
anyways thank god it was just a co-incidence my gasket moved outta place
when my lights went of thats fine now so what powers all the lights if not
the fuse battery or cdi?
mrmaxstorey: This could be a coil problem, or associated wiring. Its always best to
replace with OEM parts, I dont know enough about GSXRs to tell you whether
the 600 or 1100 or 1000 will mate up, or even the katanas, so go on ebay
and try to find some 750 coils if you suspect they are the source of the
henry martin: the battery is almost 4 years old, not charging, and no kill switch on the
bike and the side stand seems ok.
Roel Videler: So.... switch it, or smash with hammer and switch it..
mrmaxstorey: In my experience, CDI boxes will either completely fail suddenly, or just
get gradually worse. What does your spark look like?
mrmaxstorey: Ha yeah probably the CDI is ok. Check for vapor lock, float levels, and
vacuum leaks. Sometimes when your coil and spark wires get hot, if they
have a crack in the casing it will allow the spark to ground out on the
frame, causing the motor to stumble like it is running out of gas
onlyadrenaline: i have a motorcycle that uses 2 plugs per cylinder. it seems only 1 plug is
firing, other one, not at all. my coil resistance is 14kohm, book says
18-20kohm is acceptable. do you think the coils is causing poor spark?
Callahan Banbury: Thanks i'll Check
mrmaxstorey: you might be disappointed
