I am installing a 151 track on my friends 04 Viper Mtn. The hartman kit is a little more money. Is the quality worth the extra $$? Or is either one more complete , better instructions, easier install? Thanks!

Go Hartman. I have done both kits but the Hartman kit has a easy template and the instruction are excellent too. He's a good dude to help you with the gearing and clutching after seems to know his stuff.
 
from experience, hartman has a better fit and finish, better customer support, easier read directions. tom will help you over the phone, mp is a little weak on technical support. hartman works a little harder at customer satisfaction. just my opinion.
 
Hartman all the way!!!!!

Have used both MPI and Hartman , Hartman all the way ya it costs a little more but it is worth every penny. MPI is discontinuing alot off all their 2 stroke stuff and I've found them not to be very helpful. Tom has been more than helpful when I order parts or call him with a question.Just finished a 1999 MM tunnel extension and suspension relocate from Hartman .Did my 2001 MM last year from 141 to a 159. Hartman all the way.

Okay, Hartman it is! Thanks for the advice. When I tried to buy other things from MPI I remember a lot of it was discontinued or out of stock. At least the 2 stroke stuff was.
