Hi All, Has anyone fitted the 351cc big bore kit to either their KLX or D-Tracker. Im currently following up on previous intentions to research and possibly c/o the upgrade to my KLX. Have been in contact with Bill Blue in the states and he tells me that he has supplied x3 kits to Thailand, see below feedback from him: Hey Johnny, I have sent 3 351 kits to Thailand last year some of the people are using the Two Brothers Juice box to modify the injection system some have used other systems. No one has let me know how the 351 kit works with the EFI. You will need to send me your cylinder I dont have any cylinders to build the kits with it takes me 2 days to build the 351 kit from start to shipping. 351 kit is $527.45 + shipping & insurance. Im very interested to know the outcome, if its reliable or not. Have read some positive feedback on Thumpertalk, also some negative. If anyone has any info I would really appreciate some feedback/details.
