DO NOT use preventative puncture repair solutions (like slime etc etc) as you might not notice you have a puncture then go blatting down the road after your mates then have a catastrophic tyre failure (one came into the bike shop last week - wasnt pretty)

just carry a rep&air kit- http://www.infinitymotorcycles.com/p...?ProductID=182

i have had to use these kits before and have now issued these kits to all my instructors.
