1988 DT75 suzuki help

[kc1973]

I've got an 88 model DT75. I read the other post and and think that it is either clogged jets in the carb or the fuel pump gasket. It will start up great, but as soon as I try to take off it bogs down and dies. It cranks right back up and will rev up but will not go. When you rev it pretty high it will bog down too.The oil injection has also been disconected and the line going to the oil pump is pluged off. Could this have anything to do with it? I run 50:1 premix and the plugs dont look fouled. Any help would be great.
Thanks

Nope your oil pump being disconnected won't cause this, 50:1 premix is perfect, yes you are correct, it can either be your high speed jets, or your fuel pump diaphram, I will suggest rebuilding your carbs properly (soaking it in carb cleaner for 24 hours and cleaning it out with compressed air) and replacing your fuel pump diaphram .... good luck ...
