Firstly let me give you back ground then you can maybe advise better..
Done 3 years of supermoto, wasnt particularly fast, mainly i feel due to me being scared to death on the dirt on slicks. So now fancy F400.
Im looking at f400 for cost, chance to ride practically every weekend and that it seems a good place to start for a new to proper circuit racing rider. I'm fed up with the kart tracks lack of facilities and the airfields we ride at.
Been looking at getting an L model kwak zxr400 preferably race prepped. Whats the minimum i want engine wise?
I've ridden 65+hp 120kg supermotos so i'm ok with decent power. Second reason for that bike is i understand Roger Middleton is pretty handy with the zxr and is only in York, relatively close as i'm in Pontefract. Is he a good choice for engine refresh etc?
If i can split the 5k i have i'd like a wet and a dry bike. Sensible option?
I think i've read about f400 folk using the michelin cut sm slick? Is it a legal tyre?
I'm ok with working on bikes, got a decent garage and kit and a pikey caravan and van to get my bikes to circuits etc so i guess not a complete newb, happy to run at back till i find my feet.
Final question is i had novice acu licence last year, i've missed this year due to injury, will i need to through the acu course thingy?
To those that are looking to sell a bike, sorry my supermoto is up for sale so i dont have cash yet plus i've smashed up my wrist and foot on the last track day so i'm out of action for 4 months too. rolleyes.gif Ah well gives me time to learn about my new method of spending every penny i have

Cheers for any advice folks, the cards behind the bar, although this might be a one off as my insurance has just paid out.
