I installed the Worx steering kit just this week.
Called them up in Brisbane and spoke to Matt. Top technical bloke and he shipped a set off to me immediately. Got them 8:30am next day and installed them same day. Took me about 1.5 hours.
Nothing to it really just that you need the correct tools and you should proceed with caution during the removal of the OEM steering column. There are a few parts that need to be removed and added to the Worx steering kit.
I went with the suggested Protaper handlebars - Raptor - ATV bend. These work for me but I suppose it will be best to look at all options.
The only snag I experienced was that the ODI watercraft grips did not fit on the clutch side, which is roughed up and slightly larger in diameter to accommodate the snug fitting of the standard grips. Problem easily resolved with 10 minutes of filing with a good steel file.
Going for my first ride tomorrow morning.
Next I will be fitting the sponsons, ride plate and intake grate (including the pump seal kit).
I have some pics but they are too large. I will work on getting something smaller / lower res etc. I have tried attaching a screen snip.
The Matt I spoke to is from Worx.
All in with the steering column, handlebars, grips and shipping it cost me $ 750.
