Dah. Meant jet sizes.

Whats everyone using for jets in their gonna 1200? I have taper bored 44 carbs, engine bored 1 mill over, with Hot Products air filters. Thanks

I had the same but two 90' that I soldered shut to use external fuel pump but changed my mind so going back to the carb pumps. Thanks man!

Every oem pulse fitting on the intake manifold is straight, not a 90°. Like I said....

Hot Products and others. If you don't have the requested knowledge then don't reply. No one likes a smart @ss

Would it be okay if I would tig weld old pulse line holes closed to use straight fittings, I had 90° fittings and was told to use straight fittings. Worried heat may warp case. Thanks

I got over 8 years out of my 1100 till I messed with carbs and had a lean run away. Is that why the 1200 runs that partially restricted exhaust manifold gasket to keep the rear cylinder cooler? I read that about group k and rear cylinder problems. I'm just tore on if I should go back to fuel...

Okay, why did the 1200 go with 3 pulse with internal carb pumps and the 1100 went with external fuel pump and no pumps in carbs? That's what I'm wondering why yamaha didn't use external fuel pump on the 1200 but did on the 1100?

Why does the 1200 case have 2 pulse line fittings and the 1100 only One? Reason i ask is because I put a 1200 jug on a 1100 case. Thanks

That's what I thought. The external fuel pump saved my engine. If I had internal carb pumps than the engine wouldve keep running and smoked crank and major cylinder damage. Very little scuffs, just needs honed, rings and pistons.

Who would know what the squish cc is on a stock oem 1200 head? Machinist wants to know for decking.

He was laying next to you in bed when you woke up??? Sure your ski isn't a Butt Blaster??

Get back to work! That's stupid.

That's terrible man, carmpartment must of filled with fumes and then you tried starting it? What happened? Did you get hurt? What happened to ski?

Also i put external fuel pump on as i mentioned and i believe after rear seal blew out I wasn't getting much pulse to pump due to.pulse fitting being so close to rear seal that was blown out...thoughts?

Great idea with the gaskets as a template. No, I had a lean run away when my engine was a 1100 and I was adjusting the carbs due to it was running rich. I fired it up on my jet ski dock and it went wot for a long time, which I can't believe it didn't seize up. Anyhow it never ran right so I tore...

Does anyone sell block off plates for 1200?

Tore engine down due to me messing with the carbs in the Fall because it was running rich and had a lean run away. That engine was 8 years old and had cross hatch markes still in cylinder s when I took out engine to install a torrent 155 with Carter b tunnel. Anyhow after the run away I decided...
