Cheetah intake?


Recommended Posts

Where can I find intakes for my cheetah cylinders? I running 39mm carbs. I believe they are cr250 intakes or something like that. If you know of anywhere could you also please post a link. Thanks

Use the UPP intakes.

I run the upp intakes. I see no reason I need a bunch of billet aluminum in there to cause leaks. They also clear the clutch arm nicely.

 

I've used UPP and it seemed like the carbs bounced around a lot and were more prone to cracking.  The chariot/billet intakes seemed more sturdy.  Also makes it nice that they use genuine mikuni boots so they are some what interchangeable to use with different size carbs. To ea. their own. I prefer billet intakes.

UPP intakes are made of high grade polyurethane, not rubber. They are NOT more prone to cracking.  (I don't have an Opinion on the matter....I'm just stating facts.)

 

The "Genuine Mikuni" boots however ARE made of rubber and are prone to dry rot and cracking. Billet intakes have a seam where the rubber meets the aluminum. This is double the number of seams you get with the UPP intakes. Since the UPP's are one piece and have no seams.)

So expect to eventually see cracks form either at the junction on the intake or at the carb connection. 

 

 

But billet has bling tho......

 

I run UPP's and I agree.....To each there own.

I'd like to add that plasticizers are used to soften the polyurethane.   fuel/oil will eventually break down and harden these plasticizers.  it has the same effect on rubber.  Which is what happened to my UPP intakes (they were older).  We have similar problems with lane oil getting onto our distributor belts. bushings, lift wheels and other components both polyurethane and rubber based in the bowling industry.  they eventually will harden, curl and crack. which is why we have to clean machines often with a cleaner that is not aggressive (I use windex)    If there is constant stressing/moving with hardened plasticizers it will crack.

 

Not saying one is better then other..  They both have the same demons.  I just like the stability of the billet pieces.

You managed to reference "The bowling industry" without ever mentioning Balls.

 

Well played.  :jesterlaugh:

Hey now, I dont just work with balls... lol  I'm versatile

 

I'll save the affects of oils with high solids on bowling bowls of different materials for another day.  :rotflmao:

Please feel free to hold off on that indefinitely.

I really don't want to hear you describe what kind of oils and  :unsure: solids  :huh:  you spend your days cleaning off of your balls. 

Don't want to hear about finger placement, the fun you have playing on oily lanes, hard wood, or how hard your balls get from all the oil either.

 

Now before we overwhelm ourselves with bowling metaphors........I'm going to just split.  :bolt:
