What's the logic there? Pump stops pumping? OR that it pumps at low pressure and the motor runs lean? (I run a wideband and have the knock reading on the SAFC as the main reading when driving.

I'd of thought that if a drop in fuel pressure was going to blow my motor up it would have happened already with the few times I've had fuel surge issues and misfired because of it.

In which case I'd do the same thing as I did then, stop driving.

Not disagreeing, just opening up for discussion.

Just thinking, should I also be considering an adjustable regulator or do I just assume the stock one is fine?

I'm also on the fence about whether this Bosch pump will flow enough fuel, I realise the kpa ratings are within the limits I need (supposedly 300kpa base fuel pressure plus another 120 or so to account for boost) but the LPH just looks so low.

Stock reg is fine. Why dont you just buy 044 there cheap enough?

Any issues with mounting the surge tank in this location?

Hole in the spare wheel well for hoses.

The surge tank plate prohibits me putting it in the wheel well without decent modification and new fittings between the pump and surge tank.

Here's my surge tank located in a wagon - so I have had to make a steel cover for it.

Do you guys know what the rules are on sealing the boot in? I'm planning on using just an aluminium sheet over the rear firewall, do I need to cover the parcel shelf also as it has those speaker holes. I assume so?

    • Oh bugger ! Your right ! Good old hydrogen sulfide. Takes me back to the good old school days ! 
    • I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless   
    • Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.
    • You need to know I am sorry for this.  
    • As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1
