Sorry to make too much questions:hae18::hae18:

I am only off in a few hours time.

Yes if you get the Stage 1 Hot cam & the extra Raptor bits it fits staight in. Shop around for the bits otherwise cost a bit from the dealer. It was US$66 from the breakers in the USA or US$320.00 from a dealer here in Australia for the extra bits. The cam it's self is cheap as chips.

I would only recommend that you fit this cam if you have a power commander both filters & cans otherwise the gains will be small.

You need to get a 6mm X 1.0mm threaded bar to pull out the rocker shafts so the cam comes in & out. Or a slide hammer with that thread size. You can see how I did it on the very first lot of photos on the first page of this thread, I used two sockets & a long threaded bolt. The threaded bolt or bar needs to be 80mm long.

We will see what the gains are when I come back from Sydney in a few days time & can get it on the Dyno.

If you buy the stage 1 or 2 cam from Hotcams and the other rap cam bits Kev indicated, then it is a pure drop in job.

To do this, you need to remove the two bolts and side cover on the head. Then , the cam sprocket and the plate that holds the cam in place. You will also need a tool or puller to help you pull out the two rocker arms inside the head. Once they are you, you slide the Xt cam out, slide the raptor cam in, bolt it up, adjust the valve gaps and it�s ready to be closed up.

I would strongly suggest that you also remap the fuel injection as this cam will cause the motor to breath better.

The cam conversion when done right should be just as reliable as the stock cam. The stage 1 and 2 cam from Hotcam use the stock valve springs so it is not as wild as some people might think it is.

I have installed stacks of stage 2 cams on Raptor 700R and not a single one of them has had a breakdown and trust me, these bikes are hammered each time they are out there. A lot of them are used for drag racing and track racing and no mechanical problems even with the raptor revving out to 9000 RPM.

None of us have tested the gains the cam alone will give you, but if the 700 raptor is anything to go by, the cam alone will easily add 2 to 4 HP at the top end and around 4 to 8 HP at around 7000 RPM.

On the raptor, the cam alone makes a massive difference in the power output.

Ohhhhh guys thanks a million, that�s why I love this forum, here we have tech wizards that make everything easier for us and our bikes running faster.:smilies0346::smilies0346::smilies0346::smi lies0346::applause::applause::applause::applause:: applause::slywink::slywink::slywink:.

The final touch.

Kev2 dropped off my cover tonight, a job well done he machined all the letters into the cover. I will fit it tomorrow. I might change the coloured letters to orange the same as the bike.

Fantastic job, the raptor cover has an agressive racing style and a better looking.But is not necessary to change the cover when installing the raptor cam.Is it?:incon_aargh[1]::incon_aargh[1]::incon_aargh[1]:

Very nice Kev, I'd be interested to hear how liberal your police forces are there in sunny Brisbane, here in UK having a bike that is registered as 659cc and having a plate on it that says 700 would raise enough suspicions leading to your bike being given a field day by the 5-0. and a heap of trouble.

Good point there Capt, will you have to change your "log book" Kev to state the increase??? and maybe insurance??? mainly for your own benefit if anything should happen

Also you could do with new "XT700X" stickers now????????????

CaptMoto 03-04-08 15:18

Ian if you wanted to do that legally, you would have to obtain a re-matricullation of the bike by DVLA with severe inspection in regards to roadwothiness and compliance with all emission rules etc etc... I vey much doubt it you will get a "green card" if you really are keen on doing that (and you haven't heard this from me) then you are much better doing it on the quiet without having a sign sayng XT700X or something. Most coppers couldn't tell the difference at first look unless your bike is confiscated for inspection.
