Do this to the poor jetski and get a new one.298459

Nope...don't ride the 300's but I do ride these occasionally, pretty much same thing:298390

Just try it like it is, first. Keep an eye on head temps with temp strips if you can get them. Find the ideal temp at wot and see how far off you are. The rear cylinder is your most critical piece to...

I know what you're talking about...but when you start drilling holes, you can screw up the gasket. Make sure they are balanced in the number of holes on each cylinder dome. They would put larger...

Learn to ride one? One what? A 300? Why would I do that? Or are talking about learning to ride a ski? I raced for 9 years and the majority of that was in the Ocean..I raced a Kawi XIR, Yammy...

Nope...didn't agree with you just tried to be nice. I've ridden the 300 and it's bulldozer on water that feels like a boat when riding, nothing great about it to me personally unless it was the only...

Wow...brand loyalty much?:roll:

Be true and go BLUE!! Get the Yamaha FZ and you will never look back..if you stay on this forum you will learn how to make it a better ski. This forum isn't usually...

If that is the small black box with modular plug inside of the electrical box then I did swap that also along with the voltage regulator on the outside of the box. I have another box, complete...

The reason OEM says that is because they know the normal buyer of a jetski has no idea about breaking it in and will crank the ski from the dock and go bat-outta-hell the first ride. The extra oil...

Nope...your cylinder walls will just break-in with more oil differently than it would running say 40 to1 and it doesn't help. Break it in with the same amount oil you would normally run...the...

It's running too lean..make sure the carb on #3 has one jet size higher than the other 2. There's a guy that posted this years ago about NOVI's and their peculiarity...

Sent you a pm back...I'll get them out to you ASAP.8-)

It ran 85.8 @7750..but it ran 83mph on video and only 74mph at Mudbug (powervalve cable was bent). It was a good ski. It had everything on it.

Yes indeed...WFO is correct, the white flex too much and will either break or deform. What we did was added an extra bolt towards the front of the sponson (drill new hole through hull and add a...

He was truly a great man and will be sorely missed for years to come.

Good question...I only used them for a few hours and went back to OEM on the NOVI's. I bought them from a race team and have no idea about hours but they have been sitting in a box since 2005. They...

Fix it now...do NOT take that ski back out. If the piston goes kablooey, then you will have more trouble than just low compression. Take the pipes off and get that cylinder off..order new...

heck no and its starting to really get on my nerves. i can find everything BUT bcg's. dont understand that one.....well i have my theories[/QUOTE]

I got my tinfoil on...so do tell of your...

Big John sent the seat and did it fast! Good man....would buy from him again!8-) It wasn't an easy task finding a box and getting 2 seats in it! Thanks again John!

Yup...just as I suspected, small gains for a lot of work and you need to uncork the exhaust to see huge gains in the entire powerband. I do believe in making things smoother for transition of air to...

You're gonna have to get a proper tachometer first and foremost. This will be key for you now and in the future, it is a worthy investment. Now about your problem, how many hours on the engine? Have...

That was colored paint night at the place she works...well, she is actually leaving there and going to work for me. I am thinking about her wearing a bathing suit since it's so hot in our office.:D...

Great work Jim and Nater!!! I await to see your creation in the future! I can see these flying off the shelves like hot cakes if the Farthing thread is any indication of interest of a new plate. For...
