...Today I have 15g sliders, opposed to tuesday when I ran 18g sliders. 15g are great for climbing and acceleration, but it became quite evident my engine temp was way up. I never noticed because I usually run 15g but during my usually experimentaion I forgot to put my 15's back in and rode with the 18's, virtually no egine temp issues...
Are you sure you are not running too lean in the higher RPMs? It really sounds like the engine is starving for fuel at higher revolutions and causing your heat problems.
No Pete I'm not sure. Sounds like you guys believe that fuel is the most likely culprit. I'll get some plugs and see what I find out. I tell you when it comes to carburetors I'd rather not touch them. The chances of me getting them dialed in are slim to none and slim just walked out the door.

I will definitely keep ya all posted on the results. The big test will be the race. Our next race is at Firebird Raceway, a short track race. I’m told they are setting it up like a CORR track. Straight a-ways with 30 degrees of banking and turns with 30 & 40 degrees of banking. We will be running on the same course as the Trophy Trucks and Class 1 buggies. So my upgrades will be put to the test.
Glade stated he was going to send some extra jets so if I have the 145 I will try that one first.
Until then………..I have a lot of work to do. I'll post pics when completed and of the race.
Thanks again everyone for all your advice and impute. I’d been lost without it!

AZ some people use part of the original airbox and attach their filter pretty close to the same location as the stock filter. I originally use that set up and was using a mid to hi 130's jet. This current set up facilitated the larger 145. These are abs elbows and 22 degree bends, found at your local hardware/lowes/home depot stores.

Geek, I believe the concept with the rejetting and air fliter allows engine to breath/combust better. The result is reaching your max rpms quicker in return you reach max torque quicker and max hp quicker. So without rejetting/air your hindering how fast this happens. Pete if your out there chime in.

let me know on your progress and i am wondering how that 39 tooth sprocket will fit on there cause glade told me that he didn't think a 39 would fit ?
I don't think the 43 will fit. That is what comes on the new Sand vipers. The 39 should.
Glade
oh ok then i misunderstood ive done that b4 lol
greg i was just agreeing with you that i really dont want to try to dial in a carb _________________ 06 joyner 250 sand viper,red metallic..blue clutch spring 17 gram sliders
For all of you looking for shocks that fit the 250 Sand Viper I found that the stock Polaris RZR shocks are pretty much a perfect match. They are also adjustable front and rear which is nice. The only mod I had to make was on the front. They didn't fit in the allot eye hole. Lots of travel and nice and soft. I picked up a set for $100 bucks brand new take offs. Also seen several on ebay. I found mine on craigslist.org
oh cool i was thinking about new shocks for mine what did you have to do on the front ? _________________ 06 joyner 250 sand viper,red metallic..blue clutch spring 17 gram sliders
gman you have to remember that our buggy's are a little bit different then yours they are 06's so the shock lengths may not quiet be the same _________________ 06 joyner 250 sand viper,red metallic..blue clutch spring 17 gram sliders
