    So far so good Menace, try thicker O’rings in the exhaust flange, or a half reasonable engineering joint should be able to fill and clean, I’d even wager liquid metal would go the distance.

    On the subject of spooge, I would be very surprised to see spooge in the header section of any modern 2t, do you realise how fat it would have to be jetted, fat enough to never open the thermostat, cause the flame would be quenched!!!, Beside young Padawan how many times i gotta tell ya, spooge= jetting, not oil.
    Burn pattern is Ok but still not optimum especially if that’s the “Class leading” engine. Burn pattern is showing wash on the exhaust side, did you have the ign retarded for most rides?, sorta looks like it was igniting a bit latish, try a more agressive setting combined with the hardist spring will give you better snap off the bottom. Also something never discussed on these boards, but has been with pete maddo on DBW is that rediculous 36mm PWK that’s on the post 04 models, it gets the airspeed up too early, giving a hugely enhanced vacuum signal, which is why you have such small jets and thick needle on those models and not flowing air enough to realise the top end potential of the mighty 300, some blokes are boring them out (same body as mine=38mm) and getting great results with a topend surge like the pre ‘o4s had. Same as the old 500 lads used to go, slower airspeed and more volume.

    But it’s looking good bud, do a comp test 5 minutes after geting it hot first time and that’ll give you a baseline to work with.

    Clean the exhaust port a little, chamfer/take the square edge off the transfer port edges on the base of the barrel, a “B” piston and mate you won’t be unhappy one little bit

    No it’s all good, however line selection is a personal thing, the american lad riding project2twofifty reckons the opposite, as does a few of the local lads whu race both 4T & 2T.

    I personally reckon line selectio is less critical if you can “burst” out of a tight insight square off, or rail the berm, and roost is a racing tactic

    Interesting use of the word “Choose” Rocket, as afar as I am aware, only the enduro guns and FMX lads get to choose wether they want a 2T or 4T for competition. Oh Mr Honda can i ride a 2T in the SX series?…. whaddya mean my contract need reviewing.

    Besides we are speaking of taking te choice away from 4T lovers, would just like to have ours back again…

    plenty of in-depth and insightful discussions on TT about this with some good answers from some people with relevant experience in the race scene.

    A big day for us around ere on the ST will be between 80-100 klicks, whereas riding on firetrails is pisseasy to average 70 kph for a bit.

    so I concur that most people would be surprised that the average speed on a tarilbike is much lower than assumed

    Both you smart arses better “duck” when I see you next :laugh:

    Actually it is quite a good barter because everytime I see an XR650 there’s a dead wood duck somewhere in it’s tracks……

    Ducks are in short supply because they are not good at ducking traffic…….

    Xr650s aren’t in short supply, cause who’s gunna argue with one?

    Seriously thogu Mick why are wauchopians divesting themselves of their XRs…..?

    Yep Roy but not as many as a too tight one, the loose chain causes what we used to call the “Dolphin” effect the chain arcs up and down like a dolphin surfacing and diving, this causes chain and sprocket wear and slider/guide wear, but usually that’s as bad as it gets.

    Don’t advertise them we dont need every tom, dick and harry in on our best kept secret mate ;)

    It just so happens I have a spare pair of cows, some chickens a duck or two and garlic I’m trying to move at the moment, but I think the price is a bit unrealistic, given that Ducks are in short supply.

    might be able to swing a pidgeon and a canary instead.

    It does seem to happen on KTMs (PDS models- no it’s not a PDS fault) more often than others, and in their defence I reckon it’s as TB suggested, the KTMs have a very high swingarm pivot point, and slightly more overall rear wheel travel than claimed as well, which means the wheel centre travels a bigger arc than some others, there is several valid reasons for this(but i won’t go into that this time).

    Now even though the owners manual may suggest 45-55mm (or similar from memory) of freeplay find out for yourself what is needed by getting a tiedown or something squatting the suspension down so the axle is at it’s furthest point from the countershaft (direct line or straight) and see how tight the chain is and make your own assessment of how much freeplay is needed.
    A mate of mine bought a new KTM a few yrs back, he smashed the hub, ripped the swingarm and smashed botth cases and had a massive accident to boot, a $12k bike was reduced to a $800 wreck in seconds.

    I suspect the chain was too tight in that case as well.

    Check out DBW there was a wheelset for a kato on there a few days ago for sale.

    The nambotin 300 they had on display was definitely appealing to manly Blokes & non-so manly Guys, even gay bats would go and stare at it’s beauty in the evening glow of the flro lights it powered with it’s very prescence.

    There was apparently a untaken one in Vicco, but by the time I found out about it and tracked it down it was snapped up a few hours before.

    $16k on the road…..

    but still the MOST sensual dirtbike I have ever laid eyes on.

    and I still am unhappy about PDS, people who are wrong, cause they don’t agree with me, rev happy 4Ts and people who still don’t agree with me, and suzukis, and harley riders, and women, children and definitely small Doggies too.

    Umm just a point to clarify for a few, I owned a 300exc PDS for over 2 years, had Terry Hay hamburger with the lot suspension.

    I may buy one again if they get their act together on a few issues, not bashing orange, bashing poor engineering practices.

    And 4T and people who don’t agree with me, and suzukis, and harley riders, and women, small children and probably Doggies too.

    BTW I DON’T like PDS, but I do like Bikes even KTM bikes, but I’m a bit suss on those poofy GasGas now you mention it….. ;)

    they are all fun, but for ME and many others 2T is funner, I hate engine braking it takes the control away from me therider, even my last big roadies had slipper clutches fitted, I like brakes (fairly obvious eh TB?) and I brake how and when I wish to, and if I want to sail into a corner freewheeling I damn well will.

    Anyway it’s all good, keeps us intersting and relevant, cause exactly what we are discussing here is what the yanks are talking about on TT as well (I’ve missed seppomenace tho”) so it must be on everyones minds. And Barker of course that’s all I’m saying, big lazy torquey 2T in light chassis will kick ass so why wasn’t it allowed?

    Now you’ve got me going on something I’m really passionate about rocket…. :P

    equal capacity classes, 500 2t with a mild torquey power delivery in a modern chassis will eat the equivalent 4T alive in MX & SX, why do you think Honda lobbied so hard to get unequalt displacement. A 2T 250 against a 450 yep that’s making it fair. Have a look on TT for the volumes and volumes of info on this that has been discussed, including project two2fiftys’ tilt at trying to get a poor old 2502T into a national round.

    there is so much technology just waiting to be introduced into 2t dirtbikes that is tried and proven in other recreational arenas. Not that it concerns me greatly at the moment for I am a patient person, circles have a way of going around and around, see my sig for clarity….

    Menace you may ride a PDS my friend, but that is easily outweighed by the fact you are a 2T brother….. :P to quote one of my riding mates halfway up a narrow tight s/T as we stopped for a photo-op with the stupid crin on hs face “4T riders just don’t get it do they”, his rides?

    Kids have bought heaps of things out of china, had no problems at all, which is more than I can say about domestic and the USA sellers not honoring their terms.
