compression

I have messed up the compression on my bike. Did take away the compression wire and i kickt it. Now i have the compression wire on again and i feel its to easy to kick it. How do i do.

So I was out for my first ride on my new to me 2009 FE570 on Saturday. 20 minutes into the ride the bike just dies and has no compression. I figured out today that the intake valve rocker seized onto the shaft, I’m guessing from lack of oil. Apparently this is a fairly common issue unfortunately.

The bike has always been a bit temperamental, today I kicked it over to get it started and found there was no compression. Tried to adjust the valves, both exhaust valves spot on and one intake valve good but the other side adjustment screw will go through the locknut and keep going. Any ideas...

Ok need your help! fell over in water for a short time, started bike, ran for a bit and stalled!! won't start... got fuel, fire, air.... no compression ..... whats could of happen.... FE 350 Webfoot

I just tried to start my FS650e '08 and while trying to find TDC I heard a "plingy" sound coming from somewhere inside the engine. Normally I cannot push it through TDC once it's up there and I need to use the valve lift lever, but since the sound I can just push it through TDC. Please help...

Compression release lever: On my 08' FE 450 the lever is not on the bike to compression release. Is this a big deal or not ? I bought it this way, but do have the set up from another bike to put on. Should I install it ? I know there is one on the cam so ? Thanks in advance---Proflow

Hi folks :) Im looking to purchase a still in bike 06' FE650 engine & want to know the compression. The owner did it & got 60lbs & is thinking its due to the auto compression release. How can this be done so I can get a real reading ? Also if this is a tight engine does 2k US sound fair ? Is...

Hi My bike doesn't start. I suspect the compression is to low. Does anybody know what the compression values are? My plan is to measure trough the sparkplug hole. Do i have to disconnect the decompression device? If so, is it straight forward or any problems doing that? Mvh hauge

Hi there, I just joined the forum with hopes of purchasing a 570, I have a friend who is looking to sell his and I did a compression check tonight and it had about 80 PSI. The bike was cold when I tested it. I am wondering what the suggested pressure is? I have searched the inter web, and...

Hello does anyone know the compresion pressure of fs450 2008. Am doing a compression test and i cant find any info how much it should be. Thanks

Boys I need some suggestions for the good of society. '06 FE 550, Lt fork compression holder is not budging. I've tried hand ratchet, hand impact driver, pneumatic impact gun, aero kroil, mapp gas torch. I'm out of ideas. The right one came off fairly easily so at least I think I know...

Hi Everyone, My 2007 FE550 had a leaking intake boot and a leaking water pump seal... I have fixed the water pump seal and thought I had fixed the intake boot, But I have experienced a slight drop in compression I never used to be able to kick over the bike this easily, and the electric...

I have a 1994 husaberg fe 501 enduro Does anyone know what manual decompression leaver and cable would fit and were to get it from as they don't make them to fit this bike anymore Thanks

Just looking for a baseline reading of compression for a FX650 with cam decompressor. Yes - I am aware of the theoretical AND that a leak down test percentage loss is by far a better way to check - however I am currious to know what other people are getting. Now that our R6 starter mod is...

Hi All, New here, tried the search function didnt really find what i was looking for. Just bought a fe550e '05, just wondering what good compression should be? I think i'm a little low, added a bit of oil and compression didnt change much, not sure if it is good compression or the top end...

Hy Guys, I want to soften my high speed compression dampening and I believe the way to do this is to remove shims from the compression valve assembly, can I remove the compression valve from the bottom of the fork or do I need to dissassemble the forks or...... ?? Dale I would get you to do...

Hi, i own a 650 '04 and i was wondering what to do to increase the compression, after a few mails i found out that there isn't anything on the market, the only thing to do is to replace the oem head gasket with a thicker one...from 1,4mm to 0,6mm-0,8mm but i don't know the benefit of doing this...

While riding over memorial day my 2002 FE 501 was making a louder than normal clanking valve sound, so I adjusted the valve clearances and it still made the sound. I rode it a bit more and all of a sudden the bike just died, no loud sounds just stopped running. I went to kick the bike over but...

Would it be worth checking the compression every few hundred miles to see when to change the piston and rings. The manual says it should be every 90 hours (FS450e) but I think it may have had another in the past. On 2 strokes I would check the compression to see if it needed a new top end. What...
