So here is my dilemma, I'm noticing my speed drop when it's raining. I live in south Florida and I can't get away from the rain. It's not allot of rain but I think it's effecting my cvt . I took off the snorkel from the cover to give better ventilation but I am seriously thinking of putting back on. Could water even if it's a small amount effect the belt.

Water in the cvt can cause belt slip but removing the snorkel in the air box won't let water in the cvt. Unless your cover is vented water shouldn't be able to get in. Where in south Fl? We've had a crap load of rain lately. What kind of scooter? With the humidity and heat as of late it's no surprise that scoots aren't running as strong. I dropped a main jet size last night but it started pouring before I could do a test ride.

I agree with dave. I have two scooters with big vent holes on the cvt. Never had a problem with the rain getting in there. Did you check the filter element to see if it was wet after your ride in the rain? You can usually feel belt slip. Take the cvt cover off after a wet ride and then you'll know.

Thanks for the advise, I went for a ride in the rain and sure enough when I took off the cover it was dry.
Yeah the rain has been pretty bad this year. I live just outside of Fort Myers on the east coast.
Funny that you mentioned changing your jets because I was planning on getting into the carb to do the same. With a BBK. Should I go lower or higher? I am running a 95 main on a 50mm BBK.

Heat and humidity make the scoots run richer so you drop jet size. Be careful though. Your better to be rich than lean. We've got a few members in your area.

Another vote for humidity. It's prob slightly rich in dry weather and the water vapor throws it off enough that it runs poorly in wet weather. Try a 92-93 main jet and see if that's enough to cure it.
CVTs run hot and deal with water better than you'd think in small amounts. The main times I've had mine slip bad is running through standing water and getting large amounts in the CVT.

Thanks for the advice, I'm going to jet down and see the performance. I am getting a bit of sputter when I first twist the throttle. Hopefully that will cure it.

Mine looses speed when it's rainy, hot, or humid. It's not the cvt water can't get in there just from rain. 2t Dave explained the reasoning behind that. The air is thinner when it's hot or humid causing there to be less air in the fuel air mixture, causing the engine to run rich.
