thanks everyone, i think that i am going to get that new oil cap and go get a timing belt kit. any suggestions on where to get a good kit form?

 

and another thing i forgot, i want to get an apr chip is it worth the money??

 

I believe any type of chipping for the TT is worth the money. Just flashed my TT with REVO last Friday and I really like the power gain.

Make sure you get new stretch bolts, Pentosin G12 coolant, a block of wood (what Matt used), and an extra set of hands are helpful.

Check the FAQ at the top for more info on different chips and diode.
