2 Valve or 4 Valve ?
THE DEAN MACHINE replied to Youhave2minutes's topic in Speedway News and Discussions
It’s the basic principle of the more they rev the louder they are and the original silencers were straight through ones till about 10 years ago, then they put a metal block half way along the silencer which caused extra back pressure and heat so engines had to be altered to suit the back pressure and heat shields were introduced because the silencers were getting so hot, this was the cause of the cheating when riders were drilling holes in the block and then the current silencers have the same hole in them that the cheaters were doing, it’s writing stuff like this and reading it back you realise how stupid speedway really is -

The limiter was introduced and the limit is set higher than the actual revs achieved during a race, I brought a new anlas tyre last year for the upright championship on the Isle of Wight and used it again this year, so it can do 10 races when the limit is lowered to around 10,000, as bad as the tyre is it is being expected to do a burn out for 5 mins at 11,000+revs, that’s asking a lot of any tyre -

The 2valve/4 valve argument is largely redundant, it’s has no real bearing on the current state of the sport, bikes are no faster now in real time speed than they were 40 years ago, what has changed dramatically is the speed of the back wheel, engine revs now are ridiculously and unnecessarily high, japs revved up to around 6000, 2valve Jawa revved up 7500 revs, 4 valve weslake were up to around 9500 and upright GMs to around 11500, the modern GM can max out at around 13500 revs although during a race you would be lucky to hit 12,000 revs but as I said earlier overall times over 4 laps haven’t really changed, the increase in revs is causing the tyres to disintegrate and it’s causing the tracks to disintegrate and it’s also made the bikes flat out power rather than throttle control, the modern silencer has reduced the usual power down to about 2000 revs, anything out side that usable rev range and you will not go anywhere, imo the introduction of a 10,500 rev limit via the rev limiter, a better tyre and a better silencer would make the bikes easier to control, you could also do things like smaller cam lift or heavier flywheels or softer compression to reduce the overall revs of the engine, it’s not too hard to implement these measures but unfortunately the sport is run by the riders for the riders via the tuners so don’t expect anything to change anytime soon -
It might, if he can get over his confidence issue then you could have a match winner, Anyone can practice and be good at any track, racing with 3 others is another matter all together, kings Lynn is a good track with good home track advantage because of its clay base it’s 100% grip all the time and it can be an intimidating place if you’re not fully on it and as it’s clear to see boughen isn’t that guy at the moment

I’m not questioning him if he wants to ride,he should be asking himself these questions, what I’m seeing and I know other in the sport are see it too isn’t a rider who lacks ability or speed, it’s a rider who clearly has some sort of mental block in certain races and it seems to be when he hasn’t got fresh air infront of him, because of the shortness of a speedway race and most of it happens in the first 15 seconds speedway is a massive mental sport and it is bloody hard to commit to a first corner but not only is he not committing in some races he is visibly shutting off, maybe he can sort this problem in time but anyone will tell you in any motorsport, when you ride not committed is when it comes to bite you and you get hurt, I don’t know if he has had any big crashes so far and he is carrying an injury but strangely when I carried an injury I seem to ride better but I also know a big crash can take a while to get over, I had a big one at Sheffield in 96 and that stayed with me for the next 16 years, I was always weary when I went back there but I had my biggest crash at Newport and it never bothered me going back there
-
You need balls ride a bike you need confidence to race it, crashes do make you weary and the longer your career the more that weariness grows but pretty much you are over it when you get your next race win, nobody wants to crash but if this is in your mind especially in your early years of your career then you need to ask yourself should I be doing this ?

Vinnie Foord - is he too dangerous?
THE DEAN MACHINE replied to BackInTheDHSS's topic in SGB Championship League Speedway
That is correct he can and he doesn’t do anything wrong but the fact remains he was the one who turned into foord -
Definitely faking his EFs, wouldn’t really talk to anyone, kept himself to himself, not what you would call one of the lads ,after a EF when I asked what was the problem was he would just say sorted it but he never did anything to the bike, you couldn’t depend on him to win a meeting for you as you never knew when his EFs would strike but when he was good he was really good, I often thought why is he doing it but as I’ve learnt the mind is a strange thing and maybe he didn’t know he was doing it
-
But the difference is Hagon isn’t shutting off, as I posted elsewhere there is a difference between losing and shutting off, every rider sufferers a confidence loss at some point in their career but this usually results in trying harder, getting frustrated, trying different things and blaming everyone else but yourself but never shutting off
-
Don’t think you understand the mental aspect of speedway, young or old he has the ability and the speed but shutting off is different to coming last, he doesn’t like riders around him and it’s clear to see, will he get over that ?Well it’s retired many top riders in the past when they don’t want to mix it, I’m not criticising the guy, I’m just pointing out he has an issue it’s up to him how he remedies it
-
And in that race he looking across as soon as he left the start seeing where the others are, Thompsen left a bit of room not a lot but some but boughen had already decided not to go for it, he does look a natural on a bike when in infront but it’s clear for everyone to see he is shutting off going into first bends even at Oxford and he has got to get over that
