2007 zx6r engine in 1998 zx7
New member and first time poster, looking to get your thoughts on:
I had a 1998 ZX7 in which I had someone put a 2007 ZX6r engine. It's all up and running after lots of mods. 98 was completely gutted and we put in everything from 2007 like full engine n all electronics. We kept the gas tank from the 98 to match the fairings n all but put in an external fuel pump. The bike fires up and runs fine but the computer has a FUEL code on the dash. It's all good until this. Now gas flows out of the gas tank near the fuel cap. I think this is cuz of the overpressurization. For sme reason, the pressure release system doesn't work anymore and the gas flows out. This happens regardless if the bike is running or not or is cold ot hot. If I open the fuel cap, gas doesn't flow out. So, got a couple of Qs for ya:
1) will I need to use the new gas tank from the '07 with internal fuel pump n all? Would that fix the problem?
2) or can I just change the misfiring pressure release system on the '98 tank? Do you think that would fix the problem or would the problem come back again due to the high pressure from the fuel injection?
The guy who helped me do the swap and mods doesn't wanna help anymore, so any help is greatly appreciated!
Thanks fr your help!!
