check to see if the pipe is pluged up or the exhaust port is pluged.

the pipe is not pluged or the port the pipe has been off when checking
Did you burn down six times? Did you have some other type of problem? With the descriptions you are recently giving, I wonder if your crank seal is (really) bad? If I remember you were down on compression just a little so that should rule out the piston. Obviously you checked the reeds while you check the reed gaskets. Aside of a gaping hole in the crankcase or.....did you check the pulse line to the fuel pump? I don't know which side it comes from?? Wow kind of a stumper????????

make sure you dont have a broken reed pedel too.

Put the factory pipe back on and check the temps, twins are very tough to get even. Have you tried staggering the jets yet?
R
i am going to put the stock reeds back in and see if it still will not pull air through the clutch side carb.
so i put the egts on to watch the temps and now the one carb is like it is not working.
i will stager the jets if i have to but i need to now why it is not pulling air through the carb.
does anybody now any thing about timing on the sled and if that can do this
yes i burnt this thing down 6 times sence 07 i bought two of the exact same sleds in 06 and i modded out one and left the outher one stock for my freinds to ride well my my sled i got running perfect and then it hit a rock and got totaled and my second sled never ran right so i tore it down and modded it to the exact same as my 1st sled and sence 07 i have road a total of 14 miles and i have went up 6 jet sizes i did not even put it together last year just discuraged so i am know and it is not leiving my house tell it will run more then 3 milles.

what compression head are you running that you had 147psi. I had a o6 m7, carb, with twins and 15.6/1 rkt head, reeds and i was only around 125psi cold. Do you have any deto on the side that is running hotter?
R
got it i think
i am runing the highest one you can get from rktec it was special made for the old cat dealer her and when they went under i bought it they said it was a demo head i think it is 16-1 but i dont now i am at 3000 ft but you got to rember that every compresion gage reads diffrent and i run ave gas stright so i dont have any deto.
i had a freind come over on sunday that builds hill climb bikes for a living and he got my carbs dilled in. it was all in my carbs he said that the cabbs are a little off and it makes a world of diffrence it will make one carb pull more air and one pull none at idel and it shoes how much of a pain it is it took 4 hr but it sounds better then it ever has and has more responce.
on my egt i am runing 5 to 10 degres different at idel and 100 at wide open on a hard pull he said it is close enough to take to the mountain and run and tune. he said that by moving the nidle one clip it should run the same but the piston wash and plugs looked good so he said to leave it and head up and just spend a day tuneing it in.
so the sled is put up tell next year and i hope it is a good one just one day of tuning.
thank you all for the help much appriciated thanks and have a good summer.
