Dude, the content you guys are putting out is awesome! Y’all are helping this newbie out!
Watching this just may have saved my Ski 🤙🏾
never thought i would see 24 street seaside park boat launch on here. Nice Ski. Really enjoyed the content
Thanks for watching!
It was 14th street seaside park ramp but close enough!! Great eye!!
When do you torque head/cylinder bolts? After break in when it’s fully cool?
Love the vids man! Wondering when your gonna do the jet sizings and NS video.
I'm going to be building a thrust tank for tuning. And thats when ill to that video to be able to show back to back with thrust output #s and egts. Ect...
Mark, thanks for the videos. I recently purchased a 96 wave Venture 1100 for 260$. The carb rebuild video was very helpful. I studied it several times while doing the rebuild. Invested in non JIS metric screws for the carbs. It worked great. Merry Christmas, God Bless you and your family.
@@stuartbeasley7879 merry Christmas
Are you in LI by any chance? Looks super familiar.. Nice work man! Love watching your build and tip videos. You make some sick ski's!! Love the SuperJet & A/M content!!

Thanks for watching!
I want to work with ur waterski engene shop I'm very familiar since 2010/ i have 2 stroke engene 1994 model Yamaha fx1 luckily i restored everything so i work hard for this sir
Sounds sick 😎
Its an Erickson Machine and Performance waterbox. And a grumpy 1000cc engine!! This is the waterbox with a ported 701 One of our Grumy 701s!!

Pretty standard break in procedure I'd say, maybe even a bit conservative. After watching the big boys do their first starts on racing two strokes, or just running a low hour motor in general, what I really notice is the key is the consistent throttle blips. You already know this, but with every blip you are delivering a nice shot of oil to everything. For example the Japanese factories that run their old race bikes the mechanics that start and warm them up all seem to have a consistent throttle blip pattern amongst them. As long as you aren't low idling it right off the bat or holding massive throttle right off the bat, I would think the rings are going to seat real nice real fast.
The blips stop the cylinder from GLAZING on break-in. Just idling at low rpm without load can glaze the cylinder
This break-in procedure is just what I have come up with and used for MANY years. Some go shorter ( also not bad in some cases) others just go WAY TO LONG. I know some shops recommend 2 to 5 TANKS of gas for break-in which is silly in my opinion and a waste of fun time riding your new engine! Main thing is varying throttle and keeping an eye that everything is running how it should and nothing is overheating.
Could you make a video of wiring an MSD enhancer to Yamaha 701??
I would be happy to the next time 1 comes in BUT unfortunately now that I'm a Zeeltronic dealer I rarely sell them. If you need 1 done email me ericksonmap@gmail.com maybe we can work something out
I assembled a Yamaha 1200 following your methods. Used Mystic TCw3 for assembly. Do I need to premix anything for the first tank? I’m running Amsoil Intercepter for oil injection. System has been primed to carbs.
You can add alittle in the first tank. But either way your fine.
That’s an aftermarket hull right?
Mark, Do you use assemblee Goo as a gasket sealer on the block? Ex. Bottom intake gasket?
No I do not ( on engines) BUT sure builders use alittle grease to hold gaskets in place and make it easier to remove. But I do use a thin coat on carb gaskets
Hey man! How do you break in an engine that needs to be completely tuned. I have a completely new powervalve setup that has 0 hours on it. Carbs def need to be adjusted but I don’t want to be messing with it while it needs to break in.
The builder should be able to give you safe jetting and settings to get it broken in and then tuned afterwards
Hi what is the best premix ratio for break in and what are the standard carb settings for single carb 701 Many thanks
40-1 if fine as long as you used 2 stroke oil while assembling.
Just curious - approximate time you let engine cool down between sessions?
Depends on the weather. 10 min or so
What should oil mixture be for break in
If you assemble the engine like I do lubricating everything with 2 stroke oil while assembling, then just 40-1. All the assembly oil is basically the breaking oil
hi bro i am looking for kawazaki 2 stroke engine srx800 /2007 if you can help me?
yes email me ericksonmap@gmail.com
Whereabouts are you in Florida? I'm in the Treasure Coast going out today to break in my 701, thanks for the extra info
We are in New Jersey
Have fun breaking in your engine!
@@EricksonMachinePerformance thank you I appreciate it, I drove over to SBT in Tampa and bought a brand new one with my old core so hopefully it's good oh, it's in a 95 wave venture, thanks for the info.... also bought a brand new Mikuni carb
compression will read lower halfway through first tank of break in period in a ski?
It can be the same, or it coule be higher or lower. Many times it's higher from all the extra oil but every engine is different.
@@EricksonMachinePerformance I'm only half way through first tank, I have an exhaust leak and rave valve is stuck open. So running like shit, i just compression tested it when i brought it back in. compression is 20 lbs lower than when i first turned it on after rebuild
What engine?
@@EricksonMachinePerformance 787 seadoo
Hi, another stupid/ random question. I can’t decide on what 2 stroke oil to run. I need an oil that is used for both premix and oil injection. And would like to keep the same brand for my dirtbike. What do you think is a good oil?
Klutz skicraft, Amsoil Hp marine, are 2 good pwc oils
I have a gallon of the hp marine, I’ll try that. Would it be fine for a fully built js550 motor?
@@benselby6171 yes
Ok, I just looked and the flash point is only 187 (f) do you think it would be fine? Also can I use it for a oil pump?
@@benselby6171 yes both can be used with oil injection
What mix ratio do you run for break in? (Synthetic? )
32-1 or 40-1. I recommend NON synthetic for the first tank
Why non synthetic?
@@marcels.1225 on break-in you want wear. You want the rings to seat. After break-in Synthetic is optimal
Going to do a break in soon I picked up a cheapo west marine non synthetic 2 stock outboard oil. You guys think that good for a first tank break in?
Hi, random question. When adding compression to an engine do you need to decrease the spark plug gap? And if so how much? Like every 10 psi added you need the decrease the gap 0.01?
No
@@EricksonMachinePerformance do you need to increase jet size when adding compression thru a smaller cc head? or just run the appropriate fuel according to compression psi?
@@caribbeanpwc3550 depends on the setup. But normally there could be a small adjustment but not need to rejet unless on the borderline
@@EricksonMachinePerformance thanks
What do you use for fuel stabilizer? And what do you do for storage? Drain the tank or leave it full?
STA-BIL 360 MARINE TREAT GAS BEFORE LAST RUN OR LET RUN ON THE HOSE FOR 10 MIN AFTER MIX
@@EricksonMachinePerformance should I drain the tank then after running the stabil through?
@@benselby6171 nope it's good for about a year after. Just add it. Run it and leave it. We'll fog the engine and use antifreeze ect. But then just let it sit
@@EricksonMachinePerformance yeah I fog and pour pink antifreeze in the head and pipe. Now can I also use the marine stabil 360 in like lawn equipment and stuff? Main reason I’m asking is because ethanol free is hard to get here. And the octane is too low for my use
@@benselby6171 yup I use in everything
Where do you get your exhaust from
