Good info. Thanks

Gotcha. I dont pay for sparkplugs and I used to use the iridium's in my race bikes so I'd thought id give em a try in the ski. Good to know they work tho. Thanks

Anybody used these in thier SJ? The thread reach is longer than the B8HS but my wamiltons girdled head has plenty of thread left over.....I guess I could always messure and make sure it doesnt go passed the threads but has anybody tried this yet? Thanks

Installed it last night. Everything went smooth. Thanks guys.

So I guess that sensor on top is a temp sensor not a knock sensor.....Does the ecu pull ignition timing when it senses too high of a motor temp?

I just picked up a wamiltons girdled head that was originally on a 62t motor and the guy told me it would fit a 61x aswell but my question is regarding the different length cylinder bolts it comes with....There is a step up in the bottom of my cylinder on the exhaust side and I would imagine...

Was out at lake shasta over the weekend and I think I found my problem....Guy who had the ski before me stripped the exhaust manifold threads out and all 3 bolts where loosening over time. HUGE exhaust leak. Hopefully I can make some jetting progress now....

Ok. So I just shove a 60 main jet into the return fuel line right out of the carb? Seems easy enough..... I'll give that a shot and see what happens.

Ok. I'll check that asap. Which line is the return line? Im assuming the restricter creates more fuel pressure?? Im running a 2.5 needle and seat and it is holding pressure. Biggest thing that is bugging me right now is the delay between when I give it gas and when it actually picks up and gets...

Im not sure... How would I tell? Im still new to this jetski stuff. Thanks

Ok. Best combo for tonight was a 155 main and a 120 pilot. Responce is still pretty bad but once your in the sweet spot it pulls good. Still doesnt like to run at wide open throttle for too long though.... I'll have to figure out why its got a delay then it should be better aswell.

Im gonna try a 127.5 main and a 115 pilot with a 95g spring tonight after work. I'll let you know if thats any good.

I bought a bunch of jets and springs today that I will try out this weekend. I'll let you know what works best for me.

Ski Set-up: Stock 61x Wet-jet intake/Ported with cages and boysen reeds B-pipe Single RIVA POWERBOMB Carb Im riding the ski at 4000ft. It currently has a 130 main, 117.5 pilot, 115g spring. Doesnt have the response I was looking for and dies off a lot up top. It also doesnt like to run at...

Anybody know if the Super BN44 is a direct swap onto a Kawi 550? It had a standard 44 on there and we found a huge crack down the whole carb. I got him the Super BN44 and he says he having trouble installing it. Something about it hitting the head and not seating all the way.....? Maybe its user...
