Vince 9,458 Posted May 13, 2006 Scroll down this page and you can see that at least one tuner has already started working on them. Pretty good power for a 250 four stroke that has some torque as well. Share this post Link to post Share on other sites

Vince 9,458 Posted May 13, 2006 Be interesting to see how they enforce that, a lighter rod is going to require a strip down to check. Or how about honing and polishing standard items? Always very difficult to enforce such rules although the idea is good. Share this post Link to post Share on other sites
morganbike 10 Posted May 14, 2006 (edited) Have e mailed Mr Oakes for 250 homologation and rules as per advert speedway star and have asked for an entry. Will post reply. Vince , PJR 250 power is at the fly wheel but does not state which carb is being used?.Whilst you say that the CRF has no comparison it will give more than this.If tuned it will give aroung 44 bhp at the crank.Once wound up the jawa does go but lack the gating ability.When the 250 JAWA rules are enforced then yes we will run them, but as with the UK Bantam grasstrack series (which run standard honda 125 4 strokes ) if a rider has extra power it is plain to see.The exhaust note and power delivery will give the PJR motor away.In grasstrack it is up to the host club to pay for the engine to be measured after a £50 protest fee has been loged by the complaining team and If the motor is not of spec then the rider faces the fine and costs of measurement.Will the SCB follow these rules?The PJR motor will never be allowed in the Uk/world Jawa 250 speedway championship and yes they will tell a tuned motor from a standard one.Listen to the exhaust note.Lee Richardson was quoted at the Gp whilst watching the practise as saying 'I am listening to the exhaust note and can almost tell each tuner apart and who's bike it is without looking.'

highside 118 Posted July 31, 2006 good news ? but for the 250 rounds engines must std, bellam said they will be in in the next 10 days <{POST_SNAPBACK}> I think ALL engines must be standard be it 250 or 500 have them sealed so you cant tamper then its down to the riders abillity not how fast the bike is .
