morgan carbtunepron on ''PRE'' gsx750f

[gypsypunk]

hi just wondering has anybody used a morgan carbtune on a ''pre'' gsx 750f
on other threads no one has mentioned the vacuum hose

it is correct to suck the air out of the vacuum hose yes the one that goes to the back of the fuel cock on the petrol tank and then plug the hose so no air can get in/out right....

am i right or wrong i have seen posts on katriders saying just fit the morgan carbtune pro hoses into the vacuum inlet cap s and away you go

then people saying the morgan is not calibrated

Say what?

Connect to the 4 ports on the top of the carbs.
Block the tube that works the petcock.

Some people claim they require calibration occasionally but I've never experienced any issues with mine.

I was one that had issues with the Carbtune Pro not reading the same on all rods, Take all four hoses and hook them up to a single vacuum source and they should all read the same as it is one single vacuum source. I contacted Morgan and he had me send mine back and sent a new one and no issues.

Yes, easy as pie to hook up and run with.

As others have said, just make sure to plug the line from carb #4 to the petcock.
