Bargain - £4300 (pick up only- Reading) 50 Gallon Stanley tool box (worth £80) included

Oh, and to answer your question. It might not idle without a prop on.. Belt driven, clutchless jobs ie: Moster do use the prop as a flywheel, so it might idle like a bag of spanners.. (if at all)

Totally agree with Stu. Same Thor 200. Run it at idle (1200rpm max) without the prop on to get some warmth into it and bubbles out of the system. Much safer There is a chance you could do some damage if you revved the nutz off it, but summat would have had to have fallen off for it to do that, then i'd be double glad I haven't got the prop on it! Some engines (Flymec for example) need to be idled for at least 10mins to get their water cooling circulating... (they don't have a pump) I'd love to know how you would invalidate a warranty?? Unless someone grassed you up of course!

... and a Nuc WRC

Never flown a Fusion but I have always thought that the GTX was more of a toned down GTR, with lower roll rate and less tendency to dive in turns (locked in spiral stylee) I'd definitely advise you to test fly a GTX first as they are different to more conventional wings, but a lot of fun though!

Still no GTX or GTR manuals yet... I think we are supposed to be experienced enough, so as not to need one A rigging table would be nice tho'...

No they are not the same castings, but the designs are very similar... Polini's new Thor 190 is a step back imho.... Single cylinder lightweight with belt drive. Light powerful and simple design, but with enough vibes to keep my dentist happy into his retirement. The Thor200 is a lovely engine, smooth and powerful, but has a nasty tendency to go bang without without warning plus its a bit heavy. The customer service from Polini is also woeful (see Thor200 FB group!). Paul's Hornet looks great on paper, and the early reports are looking good. It ticks all the right boxes for me

Looks like he's gone full circle to me Bailey fitted with a French JPX320 or 330 boxer from 6-7 yrs ago (?). Loads of power but VERY heavy. The new Hornet looks light AND hopefully with power to match All good and is a welcome step away from the Moster / Thor / Minari clones.

Is it wedged? If not then pull the clylinder back up very carefully. You should be able to compress the rings carefully with your fingers and slide the cylinder down over the piston and rings.. If it keeps getting stuck then some neat 2-stroke oil on the rings and bore will help let it slide When you tighten the cylinder head bolts up you must torque them to the new nM settings in the latest manual Its available on the Polini site as the Polini 130 / 200 manual. If you havent got a mini torque wrench the beg/borrow/steal one If you can, get the motor pressure tested for leaks. If you have used the 'official' metal base gasket it can be a weak area for air leaks and this could cause a lean run and a holed piston. HTH! Rich P.S Or send it back to Parajet!!

After reading this I wouldnt go anywhere near one TBH http://www.paraglidingforum.com/viewtopic.php?t=57506 Ah. but our dutch friend has gone to play with his motorcycle before we could warn him... Oh well..

Those craaazy Dutch/Belwegians never do have a sense of humour...

Tell me about it m8... They say its custom and confidential, so will not give it out to anyone (even to PJ!) I've got a guy in Nottingham who could measure the needle for us as he is setting up his own needle manufacturing jig for racing, but I haven't sent it yet as the HKK works so well as a direct replacement.

I run a Keihin HKK needle, cos Polini in 'their' wisdom will not give out the needle dims.. Gives us a starting point to start playing with different needle sizes. Only problem is trying to find the more obscure needle sizes from the tuning vendors without having to pay a fortune. Friend of mine with a Supa-Tuna fitted has also re-profiled his needle after some experimentation and got his running great

Cheers Pete I'm guessing thats the MGL Velocity E1. How deep is it and where do you mount it? Nice bit of kit tho I'm with you on the metal on metal.. I was one of the first uptakers of the squish mod when it was first advised by Stef... I've had the 'official' gasket and reed mod sent, but haven't bothered to fit them, as so far my motor seems fine (fingers crossed) Rich

Thanks Peteb! Forever on the ball!

Great post Pete! Can I ask what make of EGT sender and guage you are using? We've been dabbling with these 200's for a while and every now and again one goes pop! for no reason... EGT readings make sense, but we have also been checking for airleaks. A pressure test on a freshly blown motor can reveal a crankcase seal leak which obviously causes a lean burn. I love these engines but god they have their problems... Rich

I witnessed another one of these last week. The zip had blown in exactly the same place that you describe. What has Parajet said? If its a design flaw with the Apco/PJ harness then they should be offering to fix it.

I've experienced the same problem. You can buy anti-fog sheets as an official Sony accessory but apparantly the Go-Pro ones are cheaper

Also get someone to simulate what the hang angle looks like when under power by getting them to push against the prop hub.. Some designs are more extreme than others depending on the geometry of harness/frame which can make the hang feel ok when static, but can pin you against the risers on a full power take off

Also (to answer your question) The mods are not hard to do.. Polini now supply a gasket kit to achieve the squish mod. Only special tool you need is a decent torque wrench which can accurately torque up the head bolts Takes about 20-30 mins from start to end. So far its cost me £2 for gasket paper £6 for HKK needle and the Reed stoppers are supposed to be £5

This is possibly the best worldwide group on the net for discussion anout the Polini Thor 200 https://www.facebook.com/#!/groups/174049336076750/ From personal experience I have done the gasket mod and changed to a Keihin HKK needle I am currently on the 52 slow and 144 high jets, but am probably going to change to a 50 low jet I get 188 degrees cruise and 230 max on sustained climb using those settings. Bottom end is still rich so thats why i'm changing to the 50 (not the 48 supplied with the motor) I am not sure about the new reed stoppers as I have heard (but not witnessed it yet) they only improve the mid range on the Walbro carb (I have the PWK which is easier to adjust) There's quite a few of us flying Thor 200's now and a Temp guage is a must. plus we're using a Supa Tuna and hope to fit it to my motor soon. IMPORTANT Do not be tempted to drop the needle a notch as it leans out the whole mid range and will probably hole your piston!

Its a bit late now, but both Aerofix and The Loft have a pick up and drop off service.. Should have been cheaper than using Parcelfarce

Hi, I would like to get one, but not sure if it will fit the zenith frame. Parajet told me it will, but I don't see where it will attach without the spars. High Dive Clive was flying a Polini200 Zenith when he went in, so the Agama deff fits and works! Worryingly, the Zenith's high tank design held Clive's head underwater for 10 secs until the Agama inflated. I think i'll deff fit one if I go anywhere near water from now on... Any tank mounted below the engine will do this, its nothing to do with the "high"tank design!! Yeah, semantics Pete.. i was comparing the zenith to most modern paramotors, which have the tank down by your arse.. The zenith tank is more on your lower back... prob the worst place that you want it if you end up in the drink without a floatation device... I know cos i own one

The Loft quoted me £45 for a reserve re-pack on 8th Jan 2013. I went for a full wing service (£90inc VAT) plus £12 carriage each way. Turnaround was very quick (1 week) Prices quoted were within pounds of Aerofix, so nothing in it really..
