Timing won't affect compression. You grind a metal tab off the flywheel to remove the spark timing difference.

Anyone now that its summer?

Summer time. Perhaps there is some interest now.

Yes, but you've modified it. Im not an expert. Lots of guys on here are, so I'd ask a professional. I also run like 220psi on 94 octane so short burst are the only thing keeping my engine alive lol

If the engine bay fills up with exhuast, it won't run. Beyond that, full throttle for 5 minutes? Sounds like detonation city to me.

A few things to consider: -They are a powered vehicle. They rip up trails the same as a gas dirtbike so no you cannot ride them anywhere. -They have absurdly low range and take forever to recharge. Overnight trips are not an option. - Dirtbikes hurt people. You are less at risk dragging an...

I've towed lots of broken down ski's without shut off valves without issues, how fast do you plan on towing this thing?

It makes more sense you when put the different types in the intake manifold then it becomes obvious. As for the ridge, port match it with a dremel.

96-07 superjets for the win

Sure why not? Especially with a electronic bilge to remove whatever drains in there.

Ill be damed if I ever give some random app access to my bank accounts. Freaking kids.

So then just leave the spark plugs out so the cylinders don't contain the moisture? FYI I live in AZ, we don't have moisture or winter around here so I'm just taking guesses lol

You sir are a gentlemen and a scholar.

I have to put a steering cable into this RN I aquired. I have the parts on the pic, just not sure how to mount them. The plastic collar won't close around any of the reduced diameter metal spots as far as I can tell. Which spot does it go? Does the washer go before or after the plastic ring? Am...

Sure does. I remember what I was missing now. Thanks!

I installed one of these things in my last ski but it was years ago. Got a new to me ski and am putting one in it as well. Thing is, the instructions are not what I remember. They show the wire from the start/stop switch going to two spots on the solenoid. I only remember it going to the small...

When you port them you cut a lot of that off so I'd say no it won't hurt anything.

All stock with an engine swap? lol

So I'm putting together a RN. It came as a hull with all the parts in boxes. My buddy had pulled everything for his rickter build, then bought and stripped a cheap VXR for its drivetrain and put it in this RN for his lady to ride. Fast forward to now, everything was pulled except the pump. He...

I was replacing the orings on my buddies square nose last night. The domes were marked YA7631L. I'm guessing this means yamaha 760 cylinder at 31cc? According to ada thats about 230lbs of compression?!?!? This thing has ran 91 octane for the last 5 years. It has some porting, but I've only seen...
