The knocking is not causing it to nearly quit but a result of it. When you get that carb holding pop off pressure (and this is a MUST before your ride or you go BOOM! potentially) again you can adjust your low speed mixture and mechanical idle screw to get it smoothed out. It the vibration of...
When you take the accel pump off you can put a short hose on the end that draws fuel from the body of the carb and dip it into a spray paint can lid filled with fuel. You can squeeze the spring loaded lever with your fingers and after the 3rd or 4th time it should start squirting fuel out of the...
That sucks but it's good that you caught that. As long as you get some oil in there I think it will be fine. Maybe try thinning the mess with WD40. It would help displace the water and make it easier to draw out. Any left behind would help lube and prevent rust.
I would do a compression test to see if that setup has been wearing away at things over the years. If premium fuel was used and the head dome cc size is not too small then the head should be fine.
The OP FA's are OK too if the pop off pressure was lowered or the low speed jet size increased...
There is good reason behind the 97.5 jetting being lean and then never being used again. Once they got it registered with the EPA they could concentrate on what is best for performance and the engine.
Those original 97.5 needle and seats are like 1.8's I think. Weird stuff that was quickly...
I like these better. I see others cheaper but they do not look as clean. There are a lot of sets listed but not many selling. I'd send him a offer of 125 shipped. Seadoo 951RX Dual Twin Carb Carbs Carburetors 99 | eBay

I have first over bore OEM 787 pistons for $75 each shipped and I can program a new OEM DESS key to your grey box for $75(the key itself is $55) plus shipping if it helps.
Red Dragon that is some good ole all American stuff right there! Thanks for sharing.
Dadasaurus that is a very impressive feat! Teach me the retire early trick before the rock step skills though lol.
The WSM problem was with a bad run of cb's. With only 10 hrs on it I bet they will at least sell you some better parts at cost or something, it's worth a try.
I have seen a lot of negative write ups about those aftermarket MPEM's. It could be a faulty part so don't rule that out. Yes I would advance the timing just to see how it runs but I always get high test fuel and don't run around with the throttle pinned all the time.
The ignition timing being...
That's great that he was able to work it into a good spot. That's a great RPM for a stock pipe.
The stinger location is at the small end of the pipe cone just before the coupler that goes to the waterbox. There is no fitting there but they do cast in a place for to be drilled.
Normally the...
140-150 in the waterbox where the water regulator was.
I would not go less then 100 in the mid pipe unless you put a fitting in the stinger. If you do you can run a little smaller in the mid without getting the coupler and rear riser hose too hot.
