would a dynojet kit be a good upgrade for a 2001 R1 BEC? if so how expensive are they and would it be likely to inrease BHP?
They're used more specifically in BECs to sort out the fuelling problem that's associated with using a different exhaust and airbox/filter
than comes with the standard bike. So if you have any flat spots or misfires then yes it would probably give you more BHP but otherwise I
wouldn't bother, they take a lot of fettling to get right unless you go to a proper rolling road.
Cost incidentally is around £70-£90 if I remember.
Whether a dynojet kit will improve you car depends very much on what set-up you're running at the moment. Especially if you're running a
homebrew inlet manifold / plenum you may have happened upon the perfect set-up as it is. Certainly when I took my homebrew carbon fibre inleted car
along to TTS they said it was almost spot on!!
IE bung a lamda sensor in and see what's actually happening and then see if you need to make changes....
Given how susceptible high revving bke engines are to changes in pipe and induction and bearing in mind most of these are changed in a BEC install I
would always recommend a jet kit and dyno session to sort fuelling. Our experience here is that most bike engines run lean until jetted when installed
in cars even though they make reasonable horsepower. A session on the rollers will normally result in better BHP, more torque and peace of mind that
the factory cast pistons are not slowly being spark eroded.

Andy do you have a rolling road?
As above ^^ I completely agree with Andy, IMO a dynojet kit is essential for a carbed BEC with a sausage filter & straight through exhaust can.
Get a BEC specific one from TTS, to get the correct size main jets (the ones supplied in a normal R1 bike dynojet kit are too small for your setup)
Afraid we dont have dyno here yet although one is planned. At the moment we use pdq
