Now then,

Sorry to bump up an old thread, but new member and on the hunt for Innova support.

I've fitted a similar exhaust system (also from Greece) to my carby, but it's running ever so slightly lean, going off the plug. I dare say it's lost a touch of top end pace, which might also be to do with it, more airflow, less bang.

I'm aware of Allens Performance for jets, but can anyone tell me which apply to the Innova? The APBF4A-B code doesn't give me much to work from. I'm just after a handful of the usual sizes, assuming 80 and 85 will be somewhere close.

Look forward to the replies. :D

Thanks,
Keith

Hi Keith they are the same as a Cub, 4mm thread and 7mm in legnth, standard is #75 so try an #80 or #85, i also removed the PIAR valve which makes the Carb easier to tune.

Hi Terry,

Perfect! Thanks for pointing me in the right direction. I've gone for 78, 80, 82, 85. Assuming it'll be somewhere around 80 so it'll give me something to tinker with later.

I've no intention of modifying it any further as far as the engine is concerned. I'd go as far to say it's lost top end since fitting this pipe, so no guarantee it'll stay on and it'll be back to stock main jet.

Didn't actually realise it had a PAIR valve fitted. Will look into that.

Ta,
Keith
