ok thanks for that, does the spacer actually soften the power, or smooth it out? because didn't a spacer come fitted to the 05 bikes as standard, i.e. should I keep it?cheers
Unless a spacer has been added by a previous owner then your bike being an 04 will not have one. The factory started fitting them in 05 and I think they changed the exhaust front pipe as well.
Are you trying to soften the power even further or merely curious to see what the standard power should be?
Might it be that the problem is your kickstarter and cogs and that the kickback is only a symptom of this. I know that if I was not getting a full swing on my bike then it would definetly kickback on me every time without question. Try to get the kickstarter and cogs sorted out first, then if you still have a problem maybe look at woodruff key or even a faulty stator plate.
If you are a bit limp on the boot, you may expect it!
Don't think he's Gay Copemech, but I do agree with your comments though as I hate starting mine when wearing normal shoes as it always kicks back when cold. For some reason when I wear my riding boots then kickback is vastly reduced.
I also run mine 5mm retarded as well and it has reduced the kickback, softened the power and illiminated the pinking that I was experiencing.
Only downside is that the first few inches of the exhaust chrome pipe is looking like a bit gold in colour now.
Morning Vasey15, I've got the 07 290 and had it from new. Think some of the early 06 bikes had frames that cracked across the brace under the headstock. If you keep to an 07 then they had been modded so should be ok. The 07 had a better rear shock as well which can be adjusted for damping/rebound.
Make sure the rear suspension has no freeplay or clunking when you lift up the rear of the bike. If it has then it is it will need new bearings and the shock bushes replacing. Total cost about
A magician worked on a cruise ship. The audience was different each week so the magician did the same tricks over and over again. There was only one problem:
The captain's parrot saw the shows each week and began to understand how the magician did every trick.
Once he understood, he started shouting in the middle of the show,
"Look, It's not the same hat!" or, "Look, he's hiding the flowers under the table!" or "Hey, why are all the cards the ace of spades?"
The magician was furious but couldn't do anything. It was, after all, the Captain's' parrot.
Then one stormy night on the Pacific, the ship unfortunately sank, drowning almost all who were on board. The magician luckily found himself on a piece of wood floating in the middle of the sea, as fate would have it ... with the parrot.
They stared at each other with hatred, but did not utter a word.
This went on for a day... and then 2 days ... and then 3 days. Finally on the 4th day, the parrot could not hold back any longer and said...
I did manage on my own but it was a case of wishing I had another pair of hands helping at the time. I seem to recall having one hand holding the engine stopping it from moving, another hand holding and moving the frame and then wondering when everything was lined up perfectly, how the heck do I now get the engine bolts in? If you can chock the engine at the right angle it does make life a lot easier, leaving you with both hands free to manipulate the frame and once lined up, put in the bolts. Good luck
Have a look.

Have you put an uprated rear shock/spring on your bike as the springs are normally yellow?

The adjuster screw on the 07's is at the bottom of the shock as is the spring, the shock will only fit one way.
Impossible to fit it upside down anyway!
