    As an alternative upgrade, Peter what are your thoughts on fitting a throttle body from a 2.8 V6 as per this article?

    Would this comprimise low speed tractability too much?

    what about throttle bodies? or is better to leave alone?
    could do with a bit more bottom end power......

    I did this exact modification in 2001 to my Mi16.

    I noticed no difference in power, but the throttle became much less progressive, and had more of an 'on/off' feel. I wouldn't do it again. Uncomfortable to drive sedately.

    Does the MI16x4 have the 1.9 that was detuned for Aussie fuel. If so, would the logical start point be PeterT's suggested mods to raise compression and maybe a mild cam?

    Thanks Scotty, don't want to compromise roadability, good advice.

    Yes. Fitting throttle bodies is more the way to go. Carbs are a step backwards.

    To do it properly will cost the best part of 2000 Pounds. Otherwise, get a set of PeterTs stage 1 inlet cams and play with that. Will liven it up nicely.

    Rick. Being a european car, the MI16 will have the higher compression already.

    Haha! Yea. And I called you Rick!

    CHeers for the Bumper Rich, got it yesterday. Will go nicely on the current car. The garage is a disaster. After getting rid of the Xsara its loaded with parts of all sorts! Ill be working on it most of the week if you fancy popping over for a proper look.

    You thinking of going on the Drive to the Hunter?

    Carbs on an Mi16x4? Even on an Mi16 it's sort of pointless. For example, what will you do for ignition? You either have to fit a distributor or aftermarket mapped ignition. In which case, you may as well spend a little more and fit a full fuel/ignition ecu.

    My advice is to check out www.boggbros.co.uk

    If you've decided against carbs go on ebay and search 'yamaha r1 throttle bodies'.

    Convert the carbs to throttle bodies. Lots about it on the net.
    ....now watch a Peugeot turn into a corner!

    Why Have Webers when you have a choice of either throttle bodies or Mikuni carbs?

    thanks for advice, guess webers not the way to go....
    so regards throttle bodies/ bike carbs, do they bolt straight on ?

    You'd need an inlet manifod made up for bike throttle bodies/carbs. Bogg Bros make these for a very reasonable price, just email them for a quote. They're very helpful.

    For carbs you'd need a fuel pressure regulator.
