Except that 'the BSPA' doesn't have any money ... the rev limiter should be brought in asap, though. The main trouble is that speedway engines are unique to this sport, are made in very small quantities which means that prices are very high (we have just spent £290 on a piston!). Using a new engine would simply mean that all riders, even non-paid and amateurs, would have to fork out around £2,000 for a new engine. Very nice for Jawa but not for someone trying to establish himself, paying for his racing on a low wage.
