Hi does anyone know where I can buy the easy start kit from for the ossa in the uk I have been out on the bike again today sometimes it starts first or second kick then sometimes in takes forever to start, apart from that the bike is awesome??thanks in advance

how can a modern bike need an "easy start kit".

My '10 evo lay in the shed since last March and started after 3 kicks!

Correct me if I'm wrong eddie the evo has a carb the ossa has fuel injection and that's the difference they are terrible sometimes to start but fantastic when running far far better than any machine on the market

Nigel Birkett is the Official Importer and will have the kits. Dealer Wise Colin Appleyard and Pennine Trialsport would be the nearest to me but if you look here http://www.ossauk.co.uk/?UK_Dealers then you should be able to find one.

Here are a few tips for the OSSA including how to fit the kit.

I have not seen the actual kit for sale yet as the are all being used on new bikes so there are none spare, or so I was told.

If you don,t have the 9 v battery assist fitted you should definitely put one on, it is the same principal as the new easy start kit on the 2014 models and works a treat

Mines been a pain to start last week and this week when cold, not sure I'm kicking it correctly

How's everyone else doing it ?

Try cambridge trials centre Paul knows these bikes inside out and really helpful

Mine starts 2/3 kick every time hold or cold however don't care as it's brilliant trials bike would'nt change to another manufacture technically miles ahead of the rest.

Use a high power 9v battery such as an energizer lithium, costs more but works better

It's so annoying when I was riding a section today it stalled twice or should I say I stalled it twice but couldn't re start it and carry on I had to push it away prop it against a tree and kick it over it took 4 or 5 attempts sometimes more not good really,I think I,ll speak to birketts and see if they can help or supply the kit . Apart from that the bike is superb nags of power but very smooth ??

I must admit I've been hacked off today with the starting, but once it's running it's a fantastic bike.

They are cracking bikes and look awesome but they need to start the starting issue, it's really not good when you have old bikes starting first kick when warm, sometimes embarrassing and very frustrating

Sorry sort the starting issue

The kit is really simple.If you can get a 9v battery connector and a spare kill button (not a switch!),you can make it yourself.Here's the diagram.

The difficult starting of some Ossas when others start more readily is difficult to explain.

The fundamental issue is that EFI (Electronic Fuel Injection) components (transistors, MAP sensors, TPS sensors etc) typically need a constant 5 volts to function correctly. A fuel pump could be made to operate on AC or 5 V DC but more typically they need 12V DC.

I have not been into the generating system on an Ossa butt it is probably 4 to 6 coils which produce AC peaking at over 80 volts. This will be rectified to convert it to pulsed DC then capacitors and other electrical components will be used to try to give a near steady voltage and current suitable to drive the EFI components. Capacitors and voltage regulating components store and consume energy and this has to be built up before there is sufficient power available to drive the EFI, this is why the addition of a battery helps - it pre energises these components.

The variability between bikes may be due to varying quality of diodes (which always leak electric to some extent) or other minute causes of electric power loss such as resistance in joints or surface conductivity electron leakage.

To build an EFI system without a traditional battery and charging system is quite a feat, Honda managed it but it is likely such systems will always be quirky.
