    Yeah it would make the racing crap if all the experienced guys wernt aloud in and had ammatures cause the racing weould be good but as I learnt in my early bucket days Racing against top level riders like Fishy and Bayden and Hamish and Dave you learn alot from them and it makes you ride faster to be able to compete with there wealth of knowledge

    Sorry to sound like a shitty prick but I predicted this.
    The real difference between a well set up pro twins bike and a F3 bike cost/performance wise is?
    Being totally honest with ourselves here the difference is about 5 hp and as some have said 10k

    They are too much alike plain n simple --FFS they dont look or even SOUND different from a F3 bike
    Break it down and the costs of running/building a pro twin is the same as a midfeild/top endish F3 --so whats the point?
    I figure EITHER A) go for the doctor and let pro twins be full open slather 650 twins or air cooled 750 twins. -theres enough bikes which are close now to being up there -
    but then restrict f3 to 400cc multi's and 500cc liquid cooled and 600cc air cooled twins. -let that class go back to the cheaper class it used to be
    Or B) tighten up the regulations HEAPS
    1) factory looking bodywork (glass replicas are fine)--so the bike looks like what it is
    2) NO engine mods at all including PC's
    3) restrict front fork mods to a max $ value so its basicly springs/oil/emulators
    4)Rear shocks factory
    5) muffler replacement ONLY allowed -so its not performance enhancing just louder and cheaper in a crash
    6)bike weight must be within 5% of factory spec.
    7)Replacement consumables-levers/bars/gearshifts allowed provided they perform the IDENTICAL function to the factory part
    This precludes rearsets and lower bars but does allow for cheaper (crash cheaper) alternatives.
    8) gearing to be factory gearing available for that bike.
    This is a possible area FOR CONFUSION- sv650 nakeds have different gearing to the faired model but still cuts changes down to 2 possible rear sprockets.
    9) crash protective equipment allowed -again to reduce cost

    Reeling out my old barrow--theres an easier way--75HP cap --random test of top 5 finishers.-over 75---bye bye series points.
    To see a life newly created.To watch it grow and prosper. Isn't that the greatest gift a human being can be given?

    I really respect your point of view Frosty from your experience. I too agree that power commanders, full exhaust sysyems and full f/g fairings were the wrong alley to go up and unneccessarily increases the cost of building a p/twin by a couple of grand BUT we have to look forward and not back.

    Having built an SV pro-twin on a tighter budget than a nuns date I can now look forward to cheap racing. It was a brand new bike to begin with so now I dont have to worry about any major work being needed to be done anytime soon and the tyre rule of 1 set per round of racing reduces the cost of tyres (the major cost of racing) for racing. The major challenge now is to keep the bike upright long enough to learn from the quick guys racing at club level at the moment!! Hopefully will be running the nats next year when I get my speed up and I can gaurantee full grids at the nats next year. The amount of p/twins being built up at the moment is massive and as they say, good things take time.

    I simpathise with ya-BUT RIGHT NOW with only 6 or 7 pro twins actively being ridden it would be easy to change things.
    Mate again I feel for ya-but 2k is an understatement surely
    rear shock -If you're out to win I think RT charges 2k ish
    plastics-no change from 1k painted
    performance enhancing exhaust--why not its allowed $1500
    Front end--shit skys the limit really
    PC--$450
    The tyre thing--yea good idea but then honestly ya should get a meeting a set from a pro twin anyhoo
    By meeting of course you take the OFFICIAL time on track --2 timed practices and 3 10 lap races -maybee a 15 if ya lucky
    Run last meetings tyres

    As said earlier,

    When changing the end can you need to adjust the ECU to compensate for the difference you have made on the engine and a power commander is the easiest option.

    Rear shock as I have heard is dangerous so changing to a better one should be aloud and makes the racing alot safer

    From what Ive seen its a cheap way of racing. And it allows some mods to make it a bit more interesting

    some guys get carried away with building their bikes and lose the plot really and spend a crap load. Ive taken a bog standard naked SV650K7 ($9,995 suzuki fest price) to a faired racer for $1400. Thats including front and rear suspention, slip on pipe, clip ons and raising the OEM foot pegs and braided lines, OEM "S" fairing. anyone would think Im dutch but I want max bang for buck. now time to race...

    actually dude, dont bother about the power commander, doesnt do jack all on SV's, seriously! trust me on this!

    Im not fast but I did manage 1.10 at pukie with the factory rear shock on a carbied SV (lower power)

    if h\you have a HP cap you MUST have a minimum weight. because otherwise it gets eve more expensive when everyone runs BST wheels and titanium subframes and fairings made of crepe paper (Oh, I crash damaged the last lot...)

    but you do talk a lot of sense.

    Yes please, a set of those gas pressurized Ohlins superbike forks. Oh, and I'll need some Marchesini forged wheels, and Brembo monoblocs.

    good effort. I sold my SV after pricing that stuff and thinking I didnt want to spend that much money (on a streetbike).

    My real issue is that with the rules as they stand cheating is waay to easy to do.AND to be up on the cutting edge you are gonna need the top ho suspension kit
    its not really hard to boost compression and still have the bike look factory
    Its not hard to have factory cams reground to a different profile
    The protest system we have means that if someone has cheated then you have to be specific in naming what about the bike is cheat.

    Not allowing an aftermarket rear shock would raise the tyre bill significantly, FACT. Its not only that, the rear has to be raised to load the front and afford some ground clearance and steering precision. If we went back to the stone age and didnt allow aftermarket rear shocks I can assure you I personally would be doing some very sneaky mods inside the standard gap fillers that would be very very hard to detect without a suspension dyno. Also consider that heavyweight riders require firmer springing and aftermarket springs are either not available or very difficult to source for shocks on budget entry level bikes such as the SV650 never inteded for racing ( sorry thats exactly what they are ) So its unfair to penalise lightweight and heavyweight riders if they are only allowed to use the factory shock, given also that a reasonable spring rate change needs a complimentary valving change.

    Most of the Ohlins shocks that I have sold for these are a lot closer to 1k than 2k, the over 2k ones are special handbuilt TTX36 by request and predominantly for the 2 points leaders in F3. These guys should not be victimised if they want to spend more money! They are not getting any younger and have to compensate in other areas. Bear in mind also that we provide a level of service that other players in the market just cannot hope to match.

    Moreover if you oversimplify by having suspension with either very rudimentary or no adjustments the riders and their mechanics are all at sea when they move onto more elite classes where suspension setup skills are very essential. this is not only a class to further hone your riding skills, but also your setup skills.

    If you want any experience with heavily regulated classes go to a kart meeting, the creative cheating and protest committes is an epidemic that breeds a lot of ill will......some of these guys are now in the Toyota racing series which have control shocks built by yours truly. I pulled a set apart just the other day to find that the internal valving had been illegally changed.

    they do if you fit say a M4 race system with the titaneum rear can.$1500 thank you ta -
    Sorry to be a SA but full system is worth 3hp set up right
    They breath so much better than the factory system that you need to be able to adjust the injection end
