Per the tech pages you connect nothing to the end with the adjustment screw in place? Then to adjust pull the foam off everytime? Just wanting to make sure they are so different between the SRX and viper. Thanks
 
I think you need to reread the insructions, that doesn't sound right at all. the screw end is the end that connects to the carbs. Maxdlx
 
the adjusting screw end is the end that connects to the carb top. Yes you pull it off to adjust. the foam filter goes on the other end. Make sure you keep the hose to the carb top at 26 inches, it it affects the tempa flow. Maxdlx
 
5. Outlet: Install the reducer fitting into the 1/2” i.d. tubing on the outlet end of the compensator placing it at least 3/8” from the end of the plastic screw head. Remove it to adjust the screw. Connect the reducer fitting to the vacuum source using 22-26” of 1/4” i.d. tubing (outlet tube length affects operation).
 
yes the carb hose goes to the screw adjustter end! have to remove hose to adjust!
I was thinking Barry told me to install a 90' elbow and vent the other end under the shelf?
 
Thanks guys I was confused on this part in the tech section from Holtman:

"Normally, the adjustment screw end of the body projects outside the air box and faces the engine, and is held in place by a tube with a clamp. This provides access to the adjustment screw without opening the box. Since Yamaha’s have under-hood venting (the factory vent tubes hang down and are vented below the carbs), you do not want to vent the TEMPA FLOW in the air box. The vent end is connected with tubing to a fitting which places the vent outside the air box, normally behind the box (between the box and the fuel tank). "

He just worded it funny.
 
Tempaflow

SNAKEBIT is correct - A Tempflow installed on a Viper needs to be vented inside the airbox. The instructions quoted a couple posts up would be applicable to an SRX, but not a Viper.
 
Kinger, This is a quick, simple reply. TECH PAGES. Look for Rules Tempaflow install and follow it. Took me about 30 minutes and have had ZERO issues since install. Ask Maxdlx. I changed my plugs at the Ty ride with over 2 seasons of running, and they were a beautiful cardboard brown. SRXRules install has very clear pictures that need no words to follow. Hardest part was getting that little aluminum adapter flattened in the carb top. Hope you haven't run your Viper with the setup you are describing here,because it won' trun properly without additional jet changes. Best of luck.

Dave ;)! ;)!
 
Yeah it looks like with the viper venting to the air box that the install is too simple! Just one line to the top of the carb hat and the other to the vent tubes on the carbs. That's it.

I haven't installed it yet, just prepping ;) Thanks again
 
Got my tempaflow coming and wondering what the concensus is on using a 90 degree elbow to the non screw end and venting it underneath the shelf. The pictures in the tech pages show it left blank. Do I need to add this elbow? Thanks

for it to meter accuratly it needs to be vented under the shelf. i did mine like you are doing with the 90* elbow.
 
i vented my viper under the shelf with the 90* fitting. barry has changed his description of the venting procedures stating, make sure to vent the tempaflow where the original vents are on the carbs. on the viper it is below the shelf in the box. rules burnt his down a few times and didnt like the tempaflow as much on the vipers as he did on his previous sleds. i ran my srx similar to rules' install with eric's help and it ran flawless. so the theory is sound. some sleds are more picky than others. i have tempa flows on every carbed sled i own, i trust em, and support their use. and i thank rules for teaching me about them. ski
 
Would it achieve the same thing if you connected a tube to that end and ran it under the shelf through the rectangular holes? Just thinking of ways to keep the air box as unmolested as possible. Thanks
 
It also states in the instructions to keep the small flare fitting pointing straight down as much as possible. I drilled a small hole and stuck the fitting through the shelf. I am also going to put the elbo on the vent end and runn it under the shelf as well. 10 degrees difference can really affect the jetting. Maxdlx
