decomp

Hey all, New to the Berg bikes and have worked on alot of KTM units and am in need of some advise on this issue. Can the Decomp on the kicker assy inside the transmission cover be removed completely and only use the auto on the cam and the manual on the lever? I totally understand the need for...

Hi Guys, I'm going to set the valves on my new-to-me 2008 FE 450. I've done BMW adjustor type valves but never a dirt bike with a decompression lever. Do I disconnect the spring or lever prior to checking and adjusting exhaust valves? Then when valves set ok reconnect and adjust cable free...

I just got a new autodecomp, and i wonder if it´s the right part. It looks exactly like the old part, and the only difference i can measure is on the end on where it lifts the valves. The new one is about 0.2 mm thicker than the old one...? So i wonder - how can i check if i have the "new"...

The decomp return spring on my 1997 600 is now F.U.B.A.R.ed as I have tried to bend it to make it work. The pranged part would not grip the flat part of the decomp very well and slips barely staying in place neting little to no spring tension. If I order another stock decomp spring which was...

Hi Guys, Just had a mate around who's bought an 02 FE 400...absolute prick of a thing to start....my 550 starts a heap easier...so I loked over it and observed the following. On the decomp cable when you operat it manually: 1. It feels like the decomp lever is gonna snap...

Okay, I installed the auto decomp (dutch clog)upgrade on my 98 600 last nite. I put it all back together, installed the starter and tried to spin the motor on the work bench. The starter spun till tdc and couldnt push it through a cycle. Experimenting I snugged up the exhaust valves and the...

Hi everyone. There is a little wear on my auto decomp tip. I doubt putting a small weld and reprofiling a suitable way to remedy a worn auto decomp tip since welding may ruin toughness of steel. then would it not be more vulnerable to wear? It make sense for a temporal cure. Any comment from...

i was doing a '04 650 yesterday and the camchain tension is completely used up! it's fully open. the chain, an IWIS is like new still. i suspect the chain has been rattling around. what i could do with is an old style tensioner with the blob on the end right now..... i also checked and...

in 6 months i've had three decomnp stop bolts snap. two have smacked the engine about and the third one didn't. pure and utter luck! this i believe is an age and fatigue related problem so it moves "up the charts". every chance you get, change the bolt sat in the camwheel and i'll...

I'm refurbing my '95 FE 350 and replaced the manual and auto decomp cables with new ones and need some adjustment info. What's in the manual isn't very descriptive. Anyone have some good advice. I'm bound to have more questions as I get the beast running again. Thanks!

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

just done three bikes with the later decomp that looks end on like a dutch clog. all three bikes kick over like a 2-stroke. truly a break through. at just £14 or so in the UK i think that virtually no top end work should be done without fitting it. anyone else besides ned felt the...

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'...

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...

i have the two here so i may as well let you know the difference between them to look at? the OLD one i have has the end profile of an iron for ironing clothes, it is symmetrical. has a flat face in profile at the end and a 'D' profile where the spring will slip onto. the NEW one has...

can we clarify this? i believe that the '000' came with a bobweight to suit this cam or was it a new weight that should be fitted to all bikes if possible? in which year did this happen? change in material finish? regards Taffy

Thinking about changing my auto decompression device on my cam.I read some articles on here about an upgrade on the device. It looked to be for 03 and 04.Would these upgraded parts work on my 98 600 or do I stick with the stock items? Thanks!

just a quick question on the fitting of manual decomppresor lever and cable.Onthe engine side I take it that the cable fits into the lever so it pulls in the same direction as the cable from the kick start.Is the threaded hole on the cylinder head close to the exhaust header for the bracket for...

I have a 9th month 1998 FE 501e That I think has been converted to a auto decomp system. I removed the rocker cover to repair an oil leak and noticed the manual decomp arm and cable missing and the hole plugged in the rocker cover. On further investigation I noticed that the cam shaft sprocket...
