From lack of anything better to do I though I would re-visit the CVT intake system as I had some new thoughts on where to install the box. Pulled it all back apart, took some test measurements and as it showed it might work, started to make adjustments to the box to fit the new area which was straight above the intake pipe as it comes around the frame. Had to make some angle changes to the box and plastic-weld it back together:
Then it was time to get serious and cut the intake tube and the hole in the back plastic. Before I did that I needed to see what a new intake tube was going to cost me. 48 bucks plus shipping so...about 60 bucks. Hmmm...Then I had to ask myself three questions
1. Is this going to help or hurt the value of this UTV. The answer was "hurt the value".
2. Can I rest assured the connection between the box and the CVT intake will never have a problem even on the roughest of trails. And the answer was "NO".
3. Do I really need this? Are my clutches being damaged as it is now? And the answer was NO, the filters I use work pretty well.
So, with those answers I talked myself out of doing this and put it all back together with the surface filter. So it wasn't a total loss I decided to put the spring from the Unifilter I got for the CVT into my TwinAir which is what I run in the airbox. Always thought it should have one anyway. It's been about 300 miles sense I opened up the airbox anyway and wanted to see how it was doing with the second filter on top...which I have cleaned several times over that 300 miles. I was delighted to see it was as clean in there as it was when I closed it up some 300 miles ago. Not even dust on the box interior surface and the filter as clean as it could be.
And I not sure if its because I opened up the intake tube end from 1.9" to 3" for the mushroom filter making less vacuum on the box, but I am not even getting oil vapor from the engine down the vent tube where I was before:
So the TwinAir got a full cleaning and servicing anyway and now has a Uni spring inside to keep it from being sucked-shut when it gets really caked-up....yeah, like that's going to happen....lol. I don't think I'll be checking the TwinAir for a while.
