Next question. I have seen and read about the importance of having the cases tuned and made to fit the 7t. Do any of you US residents recommend anybody here in the states to do such work.

Thanks,
Darrell

you can do it yourself
Its quite easy
you need to use jb weld on the cases

You don't need JB weld. Malossi explains in their manual, which you can find on the malossi site.

You dont have to go that far on the cases thats true
However i think you will find all the fast stuff will break through on there case porting

Nah, it just depends on how you tune it.
It's just what you prefere

If you go to the Malossi website and search for there 7T cylinders, you can download the manual and there's a explaination on how you have to tune your engine case.
