2007 Ohlins fork EC250 valving
Hi!
I just broke in my new 07 EC250 with Ohlins front and back after my previous 07 was stolen. Has anybody tried to revalve the Ohlins fork (48 EXF) to work better in the tight woods and rocks? Right now (only 4 hours on it) it is punishing me on the rocks. Soon I will change the oil and at the same time I will try the first revalving. I had good results revalving myself (with great help from KTM-Lew) an Ohlins 46. I just wanted to ask first here if somebody has experience with this newer fork so I could save time from testing. Thank you! Leon |

I'd send it to Les if you want a revalve. Personally, I added stiffer fork springs (I think they're .43s, shock spring is a 5.6), left the valving stock and am extremely happy with the suspension.

I agree. LTR is the solution. Send him the forks, riding terrain and your weight (don't lie) and he'll send back forks made in heaven.

Thank you for the replies! Actualy I live in Finland so Les is a bit faraway. I'll give it a try myself as it is very easy to check the valves. I just hoped if somebody has a baseline with it.
Should I go with bleed shims as per Marzocchi which is magic for the woods and rocks I am driving in, or with smaller pivot shim and larger taper stack (1 stage) as per KTM-Lew for the 46 which worked great as well? The shock is nice and soft (I am trying to follow the recomendations from the other post about preload... Thanks!) and I haven't noticed any disadvantage compared to the Sachs even though it's missing the high speed adjustability. I haven't touched it yet and it seems ok for my weight and ability. Best Regards, Leon |

I bet if you called or e-mailed Les, he'd give up a secret or two.

Leon I'd check things like fork oil level in both legs and that the shims match on each side. More than one has come from the factory that weren't assemble properly.
would you mind posting or pm'ing me on how you shimmed your 46's. I have a set that are good in the slow stuff but tend to be a little too soft at race pace. I'm not sure if I should change the mid valve or put more high speed dampening in the base valve. Thanks

Thank you for your replies!
From your answer and Les (through pm) it seems that the oil height might be incorrect. Actually the fork behaves like my old 46 when by mistake I put too much oil in it (something like 5 cm air gap in one and 7 in the other). I will try the minimum (130mm) air gap and let you know. The 46 had at the beggining: 3 * 20mm - 0.1 14 - 0.1 18 - 0.1 16 14 12 - 0.2 and finally I was very happy with: 3 * 20 - 0.1 18 - 0.1 16 - 0.1 13 - 0.1 10 - 0.2. air gap 110mm. I didn't touch anything else. Only the base valve. Leon |

Thanks, if it feels to harsh at 130mm raise it 5mm at a time until it feels better. If that doen't work then valving will be in order.
