Did this leak down test on a Banshee i bought today. one cylinder was weak on compression and it was huffing some smoke out the right side pipe.

Hey Kevin, I bought one of your testers and have used it a couple times and it worked flawlessly! Thanks again.
chuck billy
Very nice ! Glad your happy, tell your friends!
hey kevin i live in jalisco mexico man i love your videos. i have a 2004 banshee limited edition. man bro sure wish you could put your hands on my bike. you are a banshee master. i salute you
I used one of your testers today and it held up to the hype... The Banshee god = South Texas Banshee Heaven.
Glad to hear it!
Great video! Thank you i just purchased a banshee after 2 years of saving for it. I also just purchased your leak down tester i am going to test it and then do a compression test before i take it out riding. I would rather find any issues in my garage then broken down on the side of the trail! I love your videos great job :)
Hands down best banshee tutorials thanks for great content
Your kit and video saved my motor.
I bought this kit off you last year sometime. works amazing, done 3 motors with it.
Appreciate what you do, my man.
Start uploading again dude ur amazing at this
just bought 1. cheers mate keep the good vids coming!
yes sir!!!
Hey Kevin, do you know if the collar of the gear that fits into the clutch side of the crank seal is supposed to be grooved?
Mine has a slight groove that I assume is from wear from the seal and could also be contributing to a leak.
Hello, I’ve recently discovered that my crank case spits out oil through my vent tube while running. I split the cases and noticed that my seals are not in bad shape. Is there any other reason why it would spit out oil through the vent tube if the seals are good? Case was never overflown with oil
Make a video on how to adjust the idle and air screw. Having some trouble getting it right.
plan to soon I'm building a bike for a customer n i was gonna do it on that one on fire up.
Where do I buy a leak down tester for my banshee..thx
I have a 98 Banshee which also blows smoke from the right side so I assume that it has the same problem. Thing is it has done this since new but not knowing much (at the time) about 2 strokes I could have had it fixed under warranty. Obviously it is no longer under warranty. Do you have to split the cases to replace the seal? I have replaced timing cover seals (on cars) by drilling, inserting screw, and using the screw to pull out the seal. Could you do this or am I destined to slit the cases. Being 72, I am not as fast as you and do not look forward to pulling the engine and splitting the cases!
You CAN do it without splitting the cases. Is it the right way? No.
The seals have a lip on the outer diameter that hold them in the case. if you cut that lip off and push them in,you risk blowing it out especially during a backfire.
Leak tester to verify Jeffie going through all the work. Good luck!!!
@@kevingalindo1 Thanks for the info. I did not know the seal had a lip on it. Rather than do it the quick way, I would rather do it right and not have to worry about the seal coming out or leaking. Thanks again.
What is that plug adapters part that you have undone that clips together up toward front left side if your sitting on bike at beginning of video? When mine is unplug it runs an idle then when I plug it in it doesn't idle but it's seems faster!!
Im very confused. I have a fresh engine build. I made a leak test and everything good holds the air for more tha 10 min. No leaks. But why it leaks tranny oil from the vent case valve on the rear ?? I noticed that it leaks after I turn it on an let it idle. Im very confused. Engine sounds good and good compresion. Like I said no air leaks. Also it doesnt hace extra oil. Can anybody helps.
Hi, I have a 94 stock banshee fmf pipes, compression is within range, no leaks, carbs synced and jetted, starts 3-4 kicks... but getting a idle sputter and backfire on left exhaust... any help?
Should the center crankshaft seal hold pressure between the cylinders? I am testing on a banshee without the balance tube on the intakes.
I picked up a Yamaha blaster for my daughter and it ran good and then wouldn’t start. I did a compression test it only had 100 psi so I ordered a new piston and rings and sent the jug to get bored out and honed by a machine shop. The whole top end is brand new including gaskets and it still won’t start and the compression is still at 100 psi which it very low. I’m stumped can someone please help?
Hey south Texas my banshee is losing tranny oil I believe it’s coming out my 2 front jugs would crank seal leak be my culprit ? My banshee runs. 100 no lean or rich feeling
Hey man so went to start the banshee and started and then let it die and tried again and it made a loud pop or backfire and I started looking at stator and the cool and all the things it may be and they seem fine and now I just kick and get no response from it
I just rebuilt my banshee engine. I took it out for about 2 hours of run time and the left cylinder leaned out and seized my engine. Any thoughts or ideas why it would lean out one side. I have a trinity single carb that I've been using for about 7 years. It has a stroker crank. FMF fatty pipes and a K&N air filter.
Mine im pretty sure has a bad cylinder gasket pretty sure it leaks and that why my compression seems low after I rebuilt it wouldnt start at all and hopefully i found out why
Where can I buy a kit need it really bad and awesome video thanks
What are some of the reasons why it's a good idea to do a leak down test? Is it a mandatory thing, or is it done if the bike or running poorly?
Should i expect my 87 banshee thats been sitting for a while to have this same issue (crank seal or case seal) im about to put new cylinders and a wiseco top end in it and im just trying to figure out what to expect
What's everything I have to get to do a leak down test I'm about to build my top end and was thinking if I had to do it when I rebuild the top ? Thanks..
Hi budy..do i leave oil in the engine?and coolant temp ?...to do a leak test
Tried to order one but says it’s no longer available
hey....I recently bought your kit....can I do the test w a 2 into 1 intake? great videos
I know this vid is old, but i tested my bike and my motor leaks between the cases near my exhaust ports. Any idea what i should do to get rid of that leak? I was just thinking of stripping the whole motor down since i have a 4 mil crank just sitting
Do it lol
What made you check for a leak? I have excessive fuel coming out left exhaust would this be a diagnostic test that I should perform? I have stock carbs with TORS. I don't see a fuel adjustment on the carbs.
Miguel Hernandez
every banshee I buy I do a compression test before I make the deal. It was uneven, so I got a better deal on it, so i brought it home. The first thing I do when I get them home is leak test them, then pull the carbs about and verify jetting is correct, all jets match and needle positions are set the same. you'd be surprised how many I find with mismatched jets and needles set uneven.
Miguel Hernandez
the only thing your carbs will have is a air screw, will be on the left side toward the back of thr carbs. it's a small flathead brass screw. to me it sounds like your floats are need to be adjusted.
South Texas Banshee , thanks for your insight. I saw your video on float adjustment. I will give a try.
Can you please help me understand what that connector is under the A M in Yamaha that plug thats unplug looks like a yellow and black wire going to that connector and what's the difference with it being plugged in an then not being plugged in thanks a lot..
Shawn M
Let me look in the video n see which one your taking about. At what time in the video?
Shawn M
Oh that Shawn, That's the TORS brain box. If you don't have TORS take the whole box off and trash it. Your bike shouldn't run at all with it hooked up if you have done TORS delete.
When I hook it up it runs but don't idle and stays running while I'm giving it gas then when its not plugged in it idles and runs.. Weird Right? and this is even more weirder it seems faster when plugged in ..
I have cheetah cub cylinder with 35mm carbs. Do u sell a kit to fit them?
I use my compressor, so you don’t have to hand pump. These often have reed gasket leak, some don’t have a gasket. If you test through the spark plug as well, you can check if the reeds are working. Should not let air out the intake when pressurized.
What type of issues will the crank seals leaking cause ?
sitnlow4life it will run lean , idle can run away and it can overheat and run like shit.
hey bud where can i go to buy your kit?
duane speck
Here ya go sir.

what if the bike smokes out the left pipe on a cold start, and also popping noise like maybe a misfire from left cylinder
mis tuned carbs, as in out of synch at idle, air mixture improperly set, leak on right side causing it to be leaner, thus less smoke. popping could be a bad plug, plug cap or reeds.
+South Texas Banshee new top end and reeds , hopefully its just unsynced carbs . just ordered tors delete
+South Texas Banshee just uploaded a cold start vid can u check it out
+dshamar14 kool
Are you still selling the testers??
I am sir sorry I just saw this
the back vent hose by the rear motor mount when i do wheelies oil comes out is that normal ?
i have the banshee front lights at 12oclock for a long time so its pretty straight up
i dont have the hose hooked up to it.
so its just that plastic elbow chilling there
idk if its oil or black spluge
and it only does it when its running
i can stand in up in storage and it wont leak out sorry i know this might be confusing but i aprchatie your help..
When I do a compression test the cylinder only have 90psi on the cylinder it has a 4mill crankshaft then when I put oil down the cylinder it goes up to 150psi everything is new on bottom and top what is wrong
Derrick Tassey
Oil raises the compression, so that will be a false test. Your rings aren’t seated for some reason. If the rings are new and the bore wasn’t honed that will cause it, also new rings in a out of round cylinder that needed to be bored. Can be a lot of things.
What’s the story on the top end, when you say all new, what exactly is done?
I had i honed before I put the new rings in
I have new crankshaft new seals have stock head that’s been bord for 4mill blaster pistons Wisco 66mm pistons ported cyclinder new gasket
Derrick Tassey
long rod crank?
Yes it a hot crankshaft 158 rods long rod
So I have a banshee with compression on right cylinder at 135psi and left cylinder at 145psi. I got a leak down tester and going to check for leaks but if it passes leak down does that mean I need to rebuild the top end? I noticed one pipe smokes more then the other one. It has a cool head and 22cc domes. Just trying to figure out what my next step should be. Thanks in advance
@southtexasbanshee I tried to add you as a friend on fb to see if you could give me some advice.
traphouserecords407
Your compression is still in spec, barely but it’s in spec. It’ll run fine. Your allowed 10psi difference between the 2. The compression difference could be caused by carb issues. If one side is loading up on oil because it’s not burning it like it should it will read higher on compression.
For the uneven smoke, try syncing the carbs again, and maybe have a look at the reeds. Make sure the petals are sealing tight too the cages.
traphouserecords407 what’s your name
Awesome man thanks I appreciate it! Going to give that a try
Derrick Scott
even if I blow with my mouth those lil vent hoses air come out from my banshee
My video isn't showing
Paul Steed

They work now, it's because the ads had ended and I relisted so it gave a new item number
if my banshee ever blows how much am i looking at spending on a quality rebuild? im not sure if the previous owner bored it over or not but one cylinder seems to be on its way out slowly
04tacomaguy1
figure on 900 crank and all with gaskets and seals and petty things.
04tacomaguy1
if you don't use a new crank subtract 400 bucks
