Just finished an onyx cruiser with a grubee gt5 kit and it came out great! Shes already takin me to work twice with no problems, well four stroking at top end but i think that might work its self out after break in when the fuel mix leans out. Found out all the info i needed for the build here "and some that i didnt" and i got her togeather in less than a day with minimal throwing of tools. Will post pics soon, thanks guys.
