Here's how to replace the throttle cam with a G2 (or other). A very basic description.....

Dismantling
Remove the bar end weight.
Remove the rubber grip – I used 3 long thin screwdrivers to break the seal with the plastic holder. It wasn’t glued but needs help to get it off.
Loosen the throttle cable as far as it’ll go.
Remove the Allen screws and take the throttle top clamp off.
Lift the ‘close’ cable and pop the nipple out (you'll need to open the throttle to do this).
Drop the bottom throttle clamp and remove the ‘open’ cable nipple.

Reassembly
Take the G2 and fit the appropriate cam (I used 300 – I find the 200 too harsh and the 400 too soft).
As you will now be running metal on metal, lightly smear some grease inside the G2 grip holder and on the bar.
Put a small blob of grease in the nipple holders and cable guides on the cam.
Slide the G2 assembly onto the bar.
Attach the ‘open’ cable nipple.
Lift the bottom clamp into place.
Fit the ‘close' cable nipple.
Replace the top clamp making sure the G2 is level with the end of the bar and the cables run freely.
Refit the grip so that it’s level with the end of the G2. This is a bit of a pig but goes on OK – easier to push than pull.
Refit the bar end weight making sure it does not foul the throttle at all (a 1mm gap seems to be OK).
Adjust the throttle cable play (I leave about 1mm of play – stock was about 4mm) and pop the cable adjuster cover back on.
Check everything is tight and that the bike goes from lock to lock without the revs rising.

How to use
Go for a blast and enjoy

Pix...

Mine was silver and came with 100/200/400, no 300. But not red, either.

So what is this?



Same thing but one cam option?

Which cam is it? Why do they have no information!!!!!

You can just read 400 on the cam.

IMO 300 is best

Yep 300 cam. I would say it made the snatchiness 50% or so better.

not an answer to Mike's question but just a note to say that I modified the original throttle to represent the cam shape of the G2. I purchased a G2 throttle and decided which cam I liked best. Then I carefully traced the shape I required and took a Dremmel to the throttle. Seems to work very well.

Just fitted my G2 with 300 cam, and it makes the bike a little more bearable, but the snatch is still definitely there, and is only mildly masked by the profile of the 300 cam.

I might even try the 400, I wasn't overly impressed....!

Just fitted the 300 cam & yes makes the bike more friendly at lower revs - subtle but effective. Holding a constant throttle - even over bumps is easier. Things are definately calmer, so I'd say this is a mod worth having if you find the buckin bronco fun but impractical like me.

I might go back to 16/38 gearing now.


Thanks to Plipton for the info.
