Been working with my son on a snorkel for his 01 600 Grizz. As you can guess space was a major issue but I think I came up with something that might just kill a couple of birds with one shot. I decided to use 1 3/4 steel exhaust pipe to plumb everything to the 2 in PVC tubes that come up through the front rack. I have a new Miller MIG and he is getting better and better with it the more he does. I wanted to go with just two stacks so here is what we came up with. Left tube is just for the CVT intake and routes just under the shifter and above the(useless) pull starter. On the right of the bike I ran the carb tube down along the head to where the CVT exhaust is and put a big rubber tee that connects the exhaust from the CVT to the carb intake tube and then out to the front of the bike for the second tube. The 1 3/4 exhaust pipe is smaller in OD than PVC or anything else I found but still has a good inside diameter for flow. I read some of the posts up here about running the CVT to the carb and the issues it posed but this one is in a tee not closed one to another. My thinking is it just adds a little available flow to the carb intake and not the only supply. Also, the 1 3/4 exhaust pipe is small enough to route into the stock airbox using the original rubber airbox snorkel. Or half of it any way. We got it all put together and are working on the vent lines now. I think it looks great and it runs fine in the shop but we have not had it on a test drive yet. He says he is going to drive it in the river for a test. Guys at the boat ramp are going to think we are nuts. They are probably right. Main reason for the post is to find out what you guys think of adding the air from the CVT to the carb. Around here it is real sandy and dusty so we have to keep our filters cleaned out about every trip any-way so a little dust from the belt,I hope, shouldn’t be a issue. Seems like if the belt was going to put off that much debris it wouldn’t last as long as it does. I will post some pics as soon as he gets it finished up and put back together. One more thing I wanted to ask. I ride a Polaris and my CVT really puts out a lot of air when I rev it in neutral. You can hear it and it sounds like a turbine. My sons Grizzly doesn’t put out hardly any air in neutral. I don’t know if it does when it is in gear or not. Maybe it isn’t turning the fan till it is in gear? Just thought I would ask. I have a new belt to put on it but was going to wait till after he tests the bike in the water to put it on. I will look at how the fan works then but figured you all could tell me to ease my mind.
