Super Jet Superjet acting weird ....

[Nixon]

tuning question ......
hi guys,


I did some change to my superjet over the winter, add it : riva girdle head 35cc dome, riva intake, and sbn 46 with main 105 and pilot 130 . My superjet already had a bpipe . My ski run nice and strong but after about 10-15 minute running its start having problem taking fuel ,its like if suddenly he had too much fuel.... if I stop he is going to be ok for 30 sec-1 minute then back to problem .


would love to have your input and if not enough detail let me know ,


any help will be very appreciate !


thanks

Did you adjust your carbs after doing all that work?

Yes of course

Did you check tank vent?

Did you check tank vent?

this would be my guess... removing fuel and not getting air to fill the space creating negative pressure in the tank... quick simple test to check this would be ride until it acts up, then pop the gas cap, if it pulls a bunch of air and then runs better, your vet isn't doing its job....

it may take a few days has the weather is very poor these days ,
