Polini is my favorite kit. hands down.
Lot of people fuck theirs up. that is for sure.
Do your homework on this, and then retune your bike correctly.
You will then have a ripper that is built like a tank.
Lots of people shred theirs soo hard everyday and don't think twice about seizing or anything going wrong (I am one of them).
If Wayne told you to look at something, treat it like gold.
Also learn how to tune your carb and do plug checks for all throttle ranges while tuning.
like previously said, good premix oil 60:1 or less (depending on which oil)
just build yourself a check list and go through it.
