Yea It was dribbling a bit last season or at least it seemed like it would sometimes. I tore down the carbs and gave everything the once over and i didn't find any issues. I did find that one of the carbs had two check valves stacked while the other only had one.

Hey yaw, Does anyone know where I can order the extra thick Mikuni Check Valves?

Yea that was pretty much my plan. I did a dry fit yesterday and marked all of the bearings, so i know where they line up with the pins. I would still like to find some way to roll it on since that is the fastest way but when i did a trial run yesterday i still was running into issues where it...

Hey yaw, So what's everyone's opinion on Threebond 1184? I really want to use it over the 1211 since it is meant for case sealant and has better resistance to fuel than 1211, but when i tried it the other day, it seemed like it almost dried out faster than i could get everything assembled.

How many of yaw use Threebond 1184 over 1211? I tried using the 1184 yesterday and I was not happy with it at all. I tried putting it on with a rubber roller and it immediately started almost flaking off either the case or the roller. Then once I did manage to get a thin layer on the case halves...

Yea I watched a couple Youtube videos of guys doing this. Personally that's not how i would go about it but its interesting nonetheless. I do have a Vintage Ammco hone at work but it needs new stones and a repair to the U-Joint. I played around with the Lisle 15000 this weekend on a seadoo...

So that shiny spot one the left was just oil. I'm honestly not sure if its soot underneath or not. It didn't come off with brake cleaner and the other piston which I put in the ultrasonic cleaner looks about the same. It could have been running on the lean side though, especially if it was...

Well I can't say that I have ever bored and engine block before it can't be that much harder than machining a 1.625" bore all the way thru a 14" aluminum rod while holding a 0.0005" tolerance. lol To be fair that was on a lathe so not the same thing I know, but damn was it a pain in the ass...

I think your probably right! So when I first set up this motor I had 2 1/2" lines coming in. One going directly to the manifold and the second I split into 2 3/8 lines with one going to the 2nd fitting on the manifold and the other the pipe and then out a 3/8 pisser. Then I had 2 1/2" lines...

Per XScream the piston to wall clearance should be 0.005" - 0.007 and the rings should be gapped to 0.030" - 0.033". Not what i was expecting but i am certainly relieved to hear im still in spec. I was also told I should shoot for around 110deg F at the base of the cylinder front and back...

I have been looking for a used sunken hone as that would be ideal since I can get the double stone inserts. But I was also considering the Lisle 15000. What are our thoughts on that one?

They are forged Wiseco pistons. I have an email in to Xscream asking for more information as well as specs for piston clearance and ring gap.

So here are the measurements I got. Fwd Piston Skirt Diameter: 3.6392" Aft Piston Skirt Diameter: 3.6385" Here are the bore measurements. FYI: The. first # is line with the exhaust port (Port -Stbd) and the second # is 90 deg from there (Fwd - AFT) Fwd Bore: Top 3/8" below deck: 3.6448" and...

I had the same thought, it looked like the rings were catching just a little bit. The chamfers seem pretty small to me and I was considering touching them up just a bit to try and smooth out the transition. Granted I don't have a lot to compare them to. Mainly the giant ones that come from the...

Here ya go. The one of the right has spent some time in the ultrasonic cleaner also. Intake side: Exhaust side:

Here is a shot of the top of the piston. Looks pretty rich right?

Yea so the 130 was just with the little temperature stickers on the top of the head and on the side of the cylinder. Where I came up with that number I honestly don't remember exactly but I want to say that's where my SJ used to run and that's about the point when it becomes uncomfortable to...

First thanks for the legit reply, I really appreciate it! I'm gna start towards the end first. When I got the motor it was brand new and to my knowledge all the machine work was done by XScream. While I didn't buy it directly from XScream i did get it from a very reputable east coast hull...

What are your thoughts on freshening up the crosshatching?

I'm a big fan of the West Systems GFlex epoxy...
