compression

Can anyone explain how the compression release operates on the 09 570. My starting motor is unable to rotate mine over the top and I have ruled out the battery and conecttions.. It could be the starting motor but I am thinking the compression release is not working.

has anyone found a tool for adjusting the high speed compression on the rear shock of the 09 husabergs preferably it'll fit in the tool kit ......well hopefully anyway and be very lightweight

Hi I am going to to a compression test on my 05 550 berg what sort of figures should i be hoping for ( Say from max to min before rebuild ) . Dave

what do you all make to be the ultimate compression given your CC of engine and the type of fuel used? even the grade of spark plug would be important! i have run 13.5:1 measured on a 90mm bore. this was my old WR400. i had no problems at all. i could feel more resistance on starting...

It's been said that the 450 piston will give you an upped compression on the 550 and 650 how do I know what I have, the piston crown in mine is perfectly flat, is the 450 slightly raised. I was looking at the workshop manual nothing in particular and just happened to see on the page where they...

Is this adjustment only velocity sensitive? Is it functional everywhere in the stroke or just during the final travel? Is there a limit to it's adjustment, i.e. stops moving at 4 turns out?

just recently i had a call about the complete loss of compression feedback when kicking over. aaaah! i said, i know that feeling as well but i've never actually KNOWN what it was? it seems to happen when people have kicked for ages and all of a sudden when feeling for the engine lock -...

Well this is just a question to see if I got things right. Is the adjusters called compressiondamping and rebounddamping? If they are... that would mean that adding (+) on the compression would give you a harder suspension as you add damping to the way it compresses ... and adding (+)...

Hi! Where can i buy high compression piston to Husaberg 501 -02? :?: Greetings Roger

Ok, I think I will have to reopen the rocker cover and redo the job, I must have missed something, because after reassembling the bike, and trying to kick it, I don't have any compression. It's as if I was kicking it with the decomp lever pulled. I hear a breathing noise from the air intake, and...

My FC501 has very few miles, and ran fine before if stored it away for about two years. I am now getting ready to sell, and went through everything, new gas, cleaned our carb, adjusted valves, etc, etc. All the pre-ride stuff. Just before working on it, I just kick it through a few times and...

Hi All, I am toying with the idea of destroking my 650 back to a 550 but need to know if this is viable. I need to obtain the rod lengths, piston compression heights and case heights of the new generation vertically split engines in all their variants to ascertain if I can...

Hello all, Trying to find info on cold compression test readings? Also average variations between hot and cold readings. Engine in question is 2003 400cc semi auto (kick start) decompresor disabled. Engine still runs fine, just currious for monitoring purposes...

I want to have a bigger compression in my husaberg 650 2004.To increase the performance. What are my options??? Wossner or 100mm from husaberg 470,550.... thanks in advance Mathieu

I have a 2001 FS650e which destroyed the roller bearing on the exhaust rocker arm so I'm currently having head work done while it's apart. Has anyone milled the head to increase compression and if so, by what amount, and any negative side effects. Thanks in advance.
