Something tells me you are going to have difficulty getting a VE pump to work right on either of them......
I'm not afraid of a little jetting, I have done it before with single cylinder bikes.and while I know that a four will be more difficult to jet properly than a single, I think I am up to the task.and I believe the XJ yamaha bikes have shim-over-bucket lifters, so short of a special tool(much like the special VW tool) setting the valves should not be too bad.-Owen
This is the best for the best price.http://beemerboneyard.com/carbtune4col.htmlBike shops charge more for a one-time job. I will need one of these soon as well.I think you can sell them used for pretty close to this price. If you get good at it, you can use it to work on other people's bikes.Oh, yea...I use diesel fuel to wash bike parts off. NOW, this post can't be removed by Vince !
