Watched! Great video! Well explained and nicely edited! Flash torque wrench you've got there!
I totally forgot about this video, watching tonight!
Yeah I was waiting on some backorder parts so that delayed getting footage, already have filmed the next one so will be up this week for sure.
did you miss the o-rings that go on the 8 studs right before you put on the head gasket? great video BTW!
No, they are in there it just did not get shown well on the video. Great tip though for people watching! Thanks!
Great video! Informative, good quality. Bomb music. 10/10
Great video my friend, after you honed the ports, what was the nikasil treatment? Was it okey? I give u' a little advice put cloth covering the head of the crank, you'll avoid falling things in the sump. Don't take it to heart.
These engines have steel liners so no nikasil to worry about, most large two stroke still have steel liners for re boring purposes. You are completely right about covering the crank, normally i would but it was open for the camera. Thanks for the complement!
When you talk about the piston rings- what do you mean line the gap with the pins?? what pins? are there pins inside the gaps??
Yes, most two strokes have a locating pin in the piston ring grove. This prevents the ring from turning. In a 4 stroke it does not matter so they dont have them. But in a 2 stroke if the wrong turned the wrong edge could get caught in a port opening.
@@DeWoodysShop thank you sir!
I saw your pistons say 1.00 I guess they are 89mm pistons? Did you have to re-sleeve the jug or did you it bored out?
Just bored 1 over
Hi do u think 2001 seadoo rx,r, the same as this?and where can I order parts from?
They are similar yes. But probably the DI (direct injection) engine. I get most of my OEM parts from partzilla, and other parts like pistons, rebuild kits or crankshafts from WSM or SBT.
Do you have a part one to this?
Here is the playlist. czcams.com/play/PLDf4GdvRoWn39MhZTgxMXhDWw5hIrZ5bp.html
Can i do a top end rebuild without taking out the engine?
On a GTX you could. The hardest part will be taking the pipe off. I just took it out to make sure nothing went into the case since mine seized.
@@DeWoodysShop i succeed with taking apart the cylinders and exhaust without taking out the engine! Its not that hard ! In 2 hours it was in pieces 😁 remove cylinder head, exhaust pipe in 1 piece from manifold to water regulator, cylinders, voila 😎 ill make a video when i put it back together 😉
Great video are a mechanic or your are fixing your own?
@@mariusfauru all i can say,is very great job.i watched all your video,they are very useful and informative.thank you.👍
Is that the proper bolt order sequence to tighten?
Yes, but you are supposed to remove in the same order also but it does not matter that much removing them.
Boost ports? Trans-what ports? You mean intake and exhaust ports? 2:34
No, i mean boost and transfer ports. These are both types of intake ports. The boost ports are across from the exhaust port. The transfers are on the sides.
This picture might make more sense. images.app.goo.gl/U9uhdACmUUCVpM2C7
Necesito saber el apriete de culata cuantos nm y cuantos grados de vuelta. Si es posible mandarmelo y yo lo traduzco. Gracias.
also did you bore the cylinders if not what pistons and rings did you use
Yes it was bored 1mm to 89mm. Using WSM - 010-819-14P kit.
@@DeWoodysShop thank you one more question when i pulled the cylinder there was o rings on all of the studs just wondering what you did about those or if they even came out when you pulled of the cylinders
@@tannerorlowski1739 I have large oring sets so i just replaced them with the same size. I think the WSM rebuild kit comes with some also.
did you check the squish?
Yes, was a little down from stock at .060. But that's fine with our 93 octane here.
@@DeWoodysShop how do you check for that??
what gasket kit did you use
WSM - 010-819-14P same as the pistons and rings, comes as a kit for about 200 USD
Where can i buy top end sir do you have link thank you in advance
No link, but I just got a wsm-010-819-14P kit from ebay
Ok sir tnx a lot
