I have a big bore srx top end on my 04 viper with srx pipes and once i hit about half throttle it seems like it loads up and will not climb anymore. Sometimes if i mess around with the throttle it will clear out but still doesn't pull how it should. I was told to run an srx cdi box, but i haven't gotten one yet, will the viper cdi make it do this? I changed jetting and still no help. Any help would be appreciated...Thanks
maybe you run to mutch weight ?? what is your rpm clutch setting ect

everything is the same in the clutches as it was when i had my origional motor with pipes, hauck helix and springs. It seems more to be something electrical.

I don't know,but it seems my SRX was doing the same,it would hang up once I launched to about 7000-8000 rpm.It wouldn't pull anymore,backed off throttle and pinned it and it clears.Anyways for me,all I did was switch clutches from my other sled because it was more updated with bushings and sliders,Now the SRX pulls like it should and gets there fast.Pulls ski's up a good foot at launch and carries them ski's until I let off the throttle.Didn't do that with the original clutch I had in there most of the sesason.And here I thought it was my pilot jets or something doing it.

I don't think it's clutching because it was running good before i put this big bored top end from an srx on there. Once i get above a quarter throttle it starts spitting and sputtering and won't clear out, that's why i'm thinking it's something electrical. I already tried different jets and that didn't make a difference. I don't know what else it could be?

isn't it fun to try to find a solution to a problem on one's sled.Do the obvious,start with wiring harness,cdi,stator,plug wires,plugs.Got to eliminate one thing at a time.If it is electrical,could be something simple or something that will drive you crazy to solve.Went thru that when my Tach wasn"t working.Traced all wires and found nothing.Spent a lot of hours hunting around under the hood.I had a dead wire somewhere,but couldn't find it.I had power from the CDI,checked with meter.I decided to run a whole new wire from the box to the last connection before the tach and it now works.Coughing and spitting..something is cutting out on you or a bare wire somewhere.GOOD LUCK.
