Looks good, has a few interesting mods.

If I were to guess I would say that the seat unit is a k-conversions single seater.

That bike on ebay has my old fairings on it!!
They are doing the rounds abit!!!!
It was an RS250 seat unit I bought from race products a fair ol' while ago.
It fits ok but you have to cut a pretty huge section out on the left hand side so that it fits with the reg/reg in its original place.
I thought it was ideal for the track as it was alot cheaper than the NC30 one at the time.

looks a little like an sp1/sp2 seat unit. nice.

update.... sold this back in 2009 ish with some regret
came across it on ebay in august 2012 and got it back :-)
since i last owned it it has had lights indicators etc fitted which involved butchering the body work!!!!
it was used a couple times on track and road but is now in the process of being restored ? back to a track bike.
front forks have been uprated with ktech springs etc ,carbs sonically cleaned ,in process of completing other jobs on list..
service rear shock
