    In mean time brought a honda ns 250 r 2 stroke in bad way .

    Oh silly me i hit kill switch on vfr 750 flicked back on backfire blew two brothers muffler of.

    Notiched was slighty wiggly where riveted to the metal sealing clamp any ideas can re revit it

    back on .
    ya i got her going today runs smooth i made mistake loosing little part out the electronic

    device that hooks on to the end of the crabs and goes to the cdi and ignigtion

    so i took it of for konw i assuming i need replace the unit with new one cant see that part being sold.

    is it going be problem to run it without it .

    So far i think got 10 % more grey hair and only rode it around the block twice. scary

    Makes the vfr 750 seem like a bloody vespa am not confident i get used to it either

    Was shaking a bit gezz i never had bike do that to me not sure even why.

    That's the throttle position sensor.

    Without it I imagine the bike will be running with the timing not adjusting to rev/throttle correction.

    It should go better with the TPS on there. What bit did you lose? They are normally a sealed unit that just goes onto the end of the butterfly pivot of the end carb.

    Hi drew its tiny black plastic piece round with two slots both ends like flat head screw driver blade

    it hooks into the carb side on the end of the carb that truns then it turns the bit in the tps

    Bike works well for 79,000 km makes my vfr 750 feel slow . dam but feels like going slide of the

    Back the bike when twist the grip damm . lots torque seems just blib the trottle

    And its away i see after all these years bigger engines are cool

    Got to sort the front brakes probley new piston seals cleaning them at the moment

    (new front pads there destoryed . oh well i not going rev it to much only done 9km on it.

    I get back on the vfr and think shit this is slow hehe well just doesint just goes better with

    3000 on the dial , but surprising thing this cbr feels like revs more easily than the v4 nice.

    I had cb 750 intergra new back in day i thought was boring felt like car motoe vfr and cbr

    Are light years better .

    Should imagine i chould get engineering firm to make piece to sit inbetween move the tps

    I slid the forks back down so there flush with the tripple clamps alot better feel.

    gee going be tough choice which one to sell might need money soon pay for my mums

    Funneral .

    Post a picture mate. Sounds like you damaged the emultion (sp) tube. If it's just the jet they're easy to get.

    Yip, that's a fucked emultion tube right there.

    I'm not familiar with the CBR carbs in any detail, but they are often replaced on other bikes. You'll need to find out what way they come out from someone who has done them, or a manual.
