    Only the Mercans can write that style of marketing blumph.

    Of the product itself, the very real benefit is the humble but bloody useable PWK wears its needle jet and its non replaceable. A replacement block with new jet is a way to fix an ailing carb.

    As far as being an improvement over stock I have no idea, but there's a few people raving about them on the dirt forums having done multiple bikes. Maybe there's something in it.

    But I won't be trying one out of interest as damn they are expensive.
    Don't you look at my accountant.
    He's the only one I've got.

    The H2 may be experiencing the age old issue of overscavenging.
    The pointers are the resleeve - were the A port front walls exactly the same backsweep angle before and after ?
    And second - the low egt , a real big givaway you are dragging A/F mixture straight out the Ex duct from the front transfers.
    These old engines for sure need more rearward angle on the A port as soon as you start using an efficient ( fat ) diffuser , and the
    flat/non staggered timing edges are crap as Frits said.
    Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

    Thanks Wobbly
    So you mean it is not a problem with 204* ex duration?
    The exhaust side wall of the a-port is way more rearward aimed now then before resleeve. Before it was more aimed against center of bore now it is against boost ports (it is reed)
    The transfers are 22/10/50 but not staggered, before resleeve they were more "old school" 10/5/50
    The pipe is not fat diffuser pipes, they are typical old slim design. The previous owner of the bike use to have fat pipes but never got them to work.
    The egt was actually not any hotter before the resleeve

    How about some pictures?

    Cheers, Daryl.
    That is the most interesting part of the new TM 300 : till 2018 they had a servo + cable operated power valve and now a custom made system without cables, which should be more reliable. And now that KTM has a balance shaft, they have it too. Good thing !
    Unfortunately, it still is a copy of the honda CR250 2002-2007. It still has the typical honda exhaust...

    The problem with the H2 is probably quite complex in that you are dealing with a mix of old and new ideas, along with increased blowdown
    capability gained by lifting the main Ex port.
    The problem with the high Ex duration is that this increases the time available ( and the efficiency due to higher opening pressure ratio )
    for the diffuser to overscavenge the A port.
    You then combine this with " modern " duct exit angles , but these new angles are derived from ports that always have alot of stagger.
    Be it normal or reversed.
    Thus we have an orphan scavenging system that has no history of long development by many tuners finding out , most importantly, what
    not to do.
    Sorry but I really cant logic my way thru the changes and recommend what to actually do to fix it - as its a real left field tangent.

    George Boswell is the man behind this, I can not (yet) confirm this does or doesn?t work, but many seasoned users have given it very good reviews. I have seen his original design back about 1995 & it was very impressive the way the bikes ran and sounded.

    Here is a picture of his original design that I found on the web.

    Yep, the quantum physics wormholes are clearly visible. This must be the best thing since sliced bread. Maybe even better

    Oh gawd, that looks silly.

    The current product looks like the Keihin metering block and simply replaces that. Typically running larger jets I think the emulsion tube feed is altered.
    Don't you look at my accountant.
    He's the only one I've got.

    Dyno

    Not endorsing the product, but IF this is a true example, then gain in HP per dollar spent is a bargain.
