spring

i've been looking for a part number for the OEM dual valve springs that are fitted to the FS-C450 and thee the FC450. does anyone have a part number from their parts book? has anyone seen these valves and noted any coloured stripes on them? the stripes are the coding for the valves...

anyone else find this? the decomp is really slow to flop back home and sometimes needs to be prompted almost? i have fitted a few now and one is truly spring loaded and the next is like half stuck and needs prompting! regards Taffy

i haven't been happy with the shape of the decomp spring to go with the latest decomp lobe. on one end you have a straight arm but the action is at the other. tha manufacturer has made the spring turn back across the end of the coils. but it is infact nowhere near the shape of the 'D'...

Last weekend my Husa died on me, and after opening it i found out there was a valve spring broken. Now i'm not that technical, but it seems to be quit a job to replace it, as i need to take the camchain off and on again. From what i read on this forum, there are a lot of other things i need to...

now here is a subject that we may not have touched on before! just how much pressure is being put on the back of the tensioner blade? sparks has chopped some off and feels sure that this is part of the problem in chain wear! so sparks and i talked of how it could be measured remove...

I'm all set to install the camshaft and timing chain, but I'm concerned about the decomp weight. While viewing the sprocket end of the camshaft, cam lobes at 7 and 11 o'clock so that the weight is rotating upward against gravity, the action is nice. It feels just right. Turn the camshaft...

since i have had the 501(got it about 2 months ago) the auto decomp hasn't worked. i pulled it out and built it up with weld and re machined it to see if that was the problem.... anyway when i put it back on the spring seems to slip off the flat section on the shaft so i bent the spring to make...

Read some stuff on KTMTalk about heavy guys and the rate of the springs they use, which made me thinking about changing my reaar spring. I'm about 240lbs and on my 2004 FE 550 is the default 71-90/260 spring. If i look at the owners manual, there is an other option for a stiffer 81-99/260...

Could anyone tell me the nm's i should be tightening my clutch spring allen head bolts up to on my 650 e as the manual i downloaded says 120 nm's ? i can get them to about 40 nm's before they would start to round off. Alino :?:

In the workshop manual, it tells you to use a valve spring compressor to allow the valves to be removed and re-fitted. Can the job be done without this tool? Any home-made or improvisation ideas? Cheers

Just throwing this out there. So far we have half a dozen going. It'll be April4,5&6. I'd like to set up base camp at the old AT&T radio site at Turquoise Mtn. 12 miles n/e of Baker California. This will be a DRY camp. I'll haul 110 gallons in for the cause. One day will be riding East...

Gent's As the subject suggests. My cam operated autodecomp device flopps loosely when turned upside down. I don't recall it doing that when i first put it in. Is it a fault with the spring or do they all do that ? Will a new spring help or can i wind up the existing one, which currently...

having noticed in the doc and on the bike, an '06 450 that the spring is straight rate. would fitting my progressive rate spring have any serious downsides. really i mean will it cause anything to break. shock working poorly i can sort out, shock broken not so easy or cheap. and to...

Hi - can anyone tell me what the standard shock spring rate was for the 2001 FE 400 E ? Cheers.

I have just received my 2nd Lineaweaver racing Dual Spring Valve Spring Kit. The kit consists of inner and outer springs, bottom spring shim, and titanium spring retainers for 4 valves. Dale claims the seat pressure is the same and the peak pressure is 1/3 of OEM if I recall correctly. This...

Hi All, Does any body know the free length of the cam chain tensioner spring. I could have the right one but it seems rather long and when you eventually get it all in the tensioner housing there seem to be rather a lot of tension pushing against the tensioner blade. Just thinking that in...

02 FX 650 Ok admitedly a bone head move, but I am putting the bike back together in anticipation of Sparks stator getting here, and I cannot remember how the spring goes on the rear brake lever. Could someone explain or post or point me to some detailed photos. I know....I should have taken...

Was this thing changed between 2001 and now? The new auto decomp device does not have the groove to keep the spring in place. It used to have two, now one. Does the spring need to be changed too? Not that I cannot fix it with the Dremel, mind you. Hah there is always something (It's ok...

I have 33mm static sag with 5.5mm of preload ,and 114mm rider sag on my FC 550 05. Do you guys think I need a stiffer spring to get the 105-110 numbers to work out,or is this close enough? Thanks for opinions! I have an 8.8 and 4.8 set up for Moto,and go 212lbs no gear? :?:

I just got a new to me 02 fe501 and being as I am a big guy ( 6'3" and apprx. 320 lbs) I need to change out the rear spring. I was wondering if anyone knows what spring rate or spring # would work best. I am also a little confused about setting preload. I read the wp manual and when they talk...
