o.k., maybe i have been lost for the last couple of years but i
have been hearing about these tempa-flow's and how they are
the only way to go. i understand that they somehow adjust your
jetting from a base[low]temp and up. is this the way to go with
jetting now a days?? i have just jetted by plug color in the past
so i quess i'm out of the loop. i have thoughts about possibly buying
a set for my xc while down at the novi snow show this year but
would like to know more.............anybody??

Go to the www.holtzmaneng.com website and read all about the Tempa-flow. They work great! Spot on jetting through all weather changes.

We have the same sled and I put one on this year so ill let you know the results. (i know itll be a lil late!)

Nick its easy to install, took me about 1.5 hour to do . Just dont start drinking while your working on it! the directions can be a little confuseing but even a dumb as* like me can do it!!! I have high hopes that this is going to cure any jetting needs for the whole season! I still think any one putting parts like this in there sled should have good tuneing skills and know whats right and whats wrong..... EGT is a great tool to get a baseline set up fine tuned!

don't start drinking during the install???? man, i'll never get it done :smilielol:
i think that if i jet down to a 410 main and put these on, i should be o.k. or
won't i? haven't made up my mind yet. hard to beat a good all around old
school jetting set-up. besides, i hear you'll simply scare the shit out of
yourself by putting egt gauges on any poo domestic twin. i hear they run
hot as hell with factory jetting

My understanding of tempra-flow is you jet to be safe for the coldest weather you will face. 410 may be a bit low, 420 might be safer, and then let the tempra-flow cut the gas flow down from there. Depends on what you plan to drive in.

I have run 410's in an 01 XC 6 down to about -23 C a couple of times. Ran 50 - 70 mph trails in the cold, and, knock on wood, have not had any piston issues. I would be a bit worried on long lake runs at this temp, with 410s, but I have yet to hear of someone burn down a XC 6 because of jetting, or any other reason for that matter.

That is a good question... has anyone burnt a piston on an XC 6? I have yet to read about one. There are 6360 miles on mine now. I know Rob put ~ 10000 miles on his XC 600 back in 01, and I am pretty sure he was trouble free. I believe Rob had 410s as well, and played with the needles/pilot or air jets.

And the drinking comment, insane.... you can't hang around a garage without a pint!

EGT hot..... Na y my 01 xc-8 runs 1180*f midrange and 1100 WOT. THats not hot, you want Hot look at the EGT on a hoped up deisel..... Not uncommen to see 1500*f on a hill for over a 5 mins! try that once with a 2 stroke and about 10 seconds into it your sidelined! I nver run my xc over 1220*f , polaris H/P book says 1200 det starts and 1250 bad things can happen (poof,rattle,rattle,bang) bog!

You're better off running with stock jetting or maybe 1 size down on the mains, then running the tempa-flow. I'm running mine with stock jetting just to be on the safe side. Yeah, I might be going as lean as I could, but I like having that little bit of a buffer, especially if I run into gas that's a little suspect.

i believe my sled has 420's in it now...........i'll have to check.
i might just stay stock with tempa-flows to be safe too.
i thought i read something about you have to give them some
time to adjust after you fire the sled after sitting awhile or else
they go way lean, true??

oh and mark, give me a week or two and i'll show you some pics
of the diesel "project" i have in the works........

I am a member over on the diesel page...... Jon K. a well know member has posted he ahas seen over 1700*f for over 2 miles up hill with a gross weight of over 18K

i'm pretty sure this thing won't ever be used for nothing but street
driving and sand dunes cruising..........but it is going to be NICE!

stay tuned...........

I wouldn't say way lean, if you are really concerned just pop your hood open for a few minutes,

i've had one on my 700 for 2 seasons, lots of trail side stops, hammered after 5-10 minutes of stopping with engine off and hood closed, no problems

If you can put the tempa-flow body somewhere where it doesn't pick up underhood heat while it's sitting, then that is not an issue. Typical Poo installs are inside the airbox, and I don't know how much if any they get warmed up in there. I did one mounted in the handlbar pad because my vents were up there anyway. Needless to say it did not pick up any heat there and I could fire up and go.

It ran great from -30F to +30F, by the way. Never gained MPG though, which was a surprise.

Use stock jetting, or whatever is safe at -30F.

snowman9000 you will pick up MPG days when its warmer.... if you look at your piston wash you may find its still to rich.... tempaflow will not correct a poorly jeted carb but it will keep a properly jetted carb that way in any temp! EGT readings , piston wash and a tempaflow are a tuners guidelines to haveing a FAST sled that doesnt burn down!

hey guys just got my sled back from getting tha tempa flow installed..they jetted it for 0 degree's ..now if i run it when its like -20 out...all i have to do is turn the tempa flow counter clockwise to richen it up alittle bit for the cold air correct?

if your sleds jetted spot on at 0 *f then your going to have a problem with useing a tempaflow...... set it up spot on at -20 and it will work perfect the whole season.....

k if main jets are at 320 's right now for 0 degree's what should they be for -20?

330's.

if you turn it counter clockwise you will lean the mixture ,should have it jetted for -20 to start with and tempaflow will lean mixture as outside temp. rises.

i installed my tempa flow last week,jett your sled for -20f.i put in 420's put clip in #3 and turned clockwise 1/8 turn, adjust from there.....cant wait :beer2:
