Hi All,
I will be running in my 1988 kx500 next week as soon as i receive my head back in the post (its off getting a de-comp mod at present).
I have fitted a new wiseco piston kit, standard bore etc.
I need to know what the best oil is to use to run the bike in? Ive heard different stories in favor of both; semi-synthetic and fully-synthetic.
Some say that semi is better as it helps the piston seat better with the barrel?
Any info or advise welcome.
Thanks.
