I wouldn't use Marinetex at all, you can repair it with thickened epoxy and add black colorant to it or use thickened black gelcoat , personally I use gelcoat.. If you are wanting to do it on the cheap, grind it back enough to get all the loose flaky stuff gone and you need good clean edges...

The rotary valve which looks like a pie plate with a section missing rotates and opens and closes the intake port positively , they produce the most HP per CC of any two stroke engine setup , in this case 717 CC's 80 HP..

The biggest issue with installing them backwards is the locating pins for the rings will be in the wrong place, they have to line up with solid areas in the cylinder walls to keep the rings from getting caught in the ports. A reed engine is just a piston port engine with reed blocks added to...

Bosst port pistons, the holes line up with boost ports in the cylinder , as I said piston port engines don't usually use them , the piston skirts determine the opening and closing of the ports.

Check the exhaust for obstructions before pulling anything apart

I replied to your PM but I decided to reply here as well , maybe it will help out someone in the future who reads this . About the only way that could happen is if the pistons were installed backwards although on a PP engine with no boost holes it shouldn't matter that much , on pistons with...

It would take just as much force to rebend it as it did to straighten it , we straightened motorcycle forks and ATV axles all the time, unless they were wrecked afterwards they never came back bent.

It's like motorcycles, everyone thinks theirs is faster , one time I challenged a guy to a race , I had a Honda VT500 Ascot , he had a Yamaha RD 350LC , I just knew mine was faster right up to the point where he blew right past me.

Looking good keep it up !

As I remember it these sucked out of the box, they needed a few mods to the steering and other things to be acceptable , at any rate there are several threads here you probably should read before plopping down a big ole wad of cash on one...

BTW there are a bunch of places that can repair Megasquirt controllers if that turns out to be the issue.

I have zero experience with these whatsoever but I do have experience with Seadoos , when the MPEM direct shorts to ground on those MPEM's it is because of an $8.00 diode, if you can locate the diode without destroying other components in the process you can fix those fairly easily , I have...

I sanded that down and there were a few spots I still didn't like so I did end up pulling some more filler , this time I mixed it up not quite as heavy as usual and used a business card as a spreader , you can pull it very smooth that way if you are careful , one more light sand and I should be...

Looks like he is trying to build post count up so he can message people here. I do know this though if this ski ain't Kawasaki I don't know what is lol.

Care to explain or do we all just have to guess what you are referring to ?

In todays class we are going to cover microballoons and epoxy application techniques . So I have already pulled this with thickened epoxy microballoons a couple of times and it's pretty close to where I want it , when it gets this close I really don't want to do another epoxy pull , so to...

I feel your pain , I am sorting out a 787 RFI out of a 3D that I put into a 2000 GTX RFI , the flywheels are different and the timing is off enough where it just tries to pop , thankfully it didn't backfire. Those flywheel cups are tricky , always mark the position with a sharpie , two punch...
