Great , thanks for the info guys . i will try this over the next few days and post back with a new video to compare the two and hopfully see the diffrence :)
one last question , i have searched and read a few threads but its all talk of this protek r 2 stroke. is regualr 2 stroke (high quality one) ok to use

High quality 2-stroke is fine.

YES...Use the 10 OZ (4-500 mil) INITIALLY on a full tank of Petrol..

See how that goes then perhaps scale it back...and report back here.

Yes, a Good Quality 2 Stroke for Bikes is excellent, try and avoid TCW III for marine use.

I use Amsoil Saber Pro (Expensive) so is Motul 800...you get the drift..

You won't hurt anything (including Injectors..that is rubbish), your engine will thank you for regular Pre-Mixing of around 6-8 Oz, you WILL notice better performance and smoothness.

It gives you better compressions.

seth151, could you add you location to your profile? I don't want anyone trying to give you advice that fits for North America, that would not fit for your location in the UK.

I think he is UK???...but that does not change Pre-Mix application or recommendations.

Plus he has the Union Jack on original #1 post :)

I put that there after I traced his IP to the UK. Maidstone actually, S.E. of London.
That doesn't change any of your recommendations. Someone that doesn't know any better may start spouting warranty information or something of the sort not realizing that it doesn't fit for his location. It's happened many times.

not to sound alarmist but i still think a compression check is warranted . It kinda sounds like blowby possibly from a side seal seeing as it seems to run pretty good otherwise .

I hope you get it all sorted out you must have spend a fortune on all the parts. I just have a my CAT replaced in Florida all emissions related parts are covered be a 7 year manufactures warranty not sure about back home in the UK

Hi guys thanks for all the advice and help :)
Started my premix today at first im sure i noticed a change in the sound but might have been in my head lol,ive done 100 miles so far on the premix.
The car defo feels a lot smoother when driving,now im premixing should i do the disconnect battery trick and brake pumping to reset every thing or would this be pointless?
I will up date my profile straight after i type this :)
And yeh thats the dishearting thing when i bought the car i thoguht i had a bargain and then used all the spare cash i had doing what i have done so far which has fetched around £2000.
a really silly question but do u think it would be worth me taking it to another exhaust garage to double check no exhaust leaks from the manifold area (maybe a lose bolt)
And brettus if the problem gets any worse wat so ever then a compression test is my next move i think , thanks for the advice , much <3
My tranny fluid hasnt turned up yet :*( im dying to change this to see how it feels :(

P.S LOLOL i was with my bro and good friend earlier when adding the 2 stroke to my tank and you should have seen there faces and the other peoples in the garage LOL
they was like "WTF! why are u doing that!" .... premixing here in uk isnt a regualr thing i dont think :P

When you seafoamed, did you notice white smoke coming out of anywhere but the tailpipes?
If yes, that's your leak if there is one.

For whatever reason, catless rotary exhaust stinks! One of many reasons I will not run without one.

At some point have a Mazda dealer check to see that the engine control unit (PCM) has been given the MSP-16 reflash which came out in ~2007 for the USA. I don't know if it applies to UK, but it does address a number of driveability issues, including flooding. At least here, the Mazda dealer will flash it for free.

Have not had an engine with a side seal failure myself so can't say how it would sound . Have had a blown apex and the sound is similar but way more intense . With an apex the engine runs very poorly which is not the case for you . Hence the sideseal comment .

I would imagine a sideseal failure would allow a lot of blowby into the crankcase which would lead to a lot of oily gunk in the intake and diluted oil - might be worth checking both .....

Vibrates at idle. Check the passenger side "motor mount". There is a TSB, but Mazda is not replacing them. The new one is improved. It is fairly easy DIY. You can try filling the old one with polyurathane or similar. Search RX8club for DIY.
