When the chap down the road looked into a disc valve arrow project he worked out that some of the casting could altered but 75% was to be thrown out. Fahron has the patterns for alloy cylinders but I understand none have been done for a while. Could you be the one to rekindle rons interest.

Ron always had plenty of blank castings on the shelf, be surprised if they've all gone.

Pay Nova to make 10 sets and try and sell the rest (I know there's a few people hoping they'll make some more)....
Speak nicely to Pete Coogan to see if he has any spare boxes he'd part with.....
Cut the back off and fit a different box altogether (possible because it's in a different frame)....

Saw the project when it was on a certain site, It sounds good to resurrect a period racer. I think it mentioned a magazine article on the bike too?

Nova currently advertise a 6 speed box for the Arrow but god knows how much it will cost. Good luck with the project Nige, a mate of mine raced an Arrow in the 70's.
I'm only old on the outside.

never going to be cheap Tony but ime not in to deep with the project cash wise & it came with a few spare engines, believe it or not one arrow 125 single motor with side induction reed valve & a 500 V4 with two motors doubled up! more of a curiosity than anything usefull lol

That reed valve 125 sounds interesting. Not the one Ron did as a magazine competition to create a complete 125 in a time constraint. The 500 would just be one of those projects that never get reliable. I remember Will loader mention a reed valve 250 done in the day. That would make an easier ride with the possibility of equivalent power at lower revs.
