Harsh Cer Forks.

3C still has its Ceriani's no issues here  :o

The original Cerianis were great shocks in their day, as were the Konis. Times have moved on. Hmmm, just thought about that, Laverda's were leading edge in their day as well...
 
I've bitten the bullet and gone a pair of top-line Nitrons from DAM Laverda. Like Ohlins, they are far from cheap, but are the bees knees. I figured i won't be doing any more custom builds on this bike, so I finally want to finish what i started two or three decades ago right.

Very much looking fwd to reporting back on them ...
 
Me too, how far off are you. I would love a topend pair of shocks, they if tuned right they just perform but most are at least $1500 and more.
 
When I put a pair of YSS shocks (replacing the Marzocchi Stradas) on the back of my MHR a few years ago, they made a big difference. The bike was a lot more comfortable to ride and the rear wheel actually stayed in contact with the road over bumps. I could get off the bike after an hour of riding without feeling like I'd been kicked in the arse a thousand times.
 
My 35mm Cerianis were a brilliant road fork for the era. Definitely not harsh if set up well and I think they even had bushes of some sort so stiction was not bad.
My build is a combo of waiting game getting work done externally and lack of time doing stuff myself. Been waiting nearly 4 weeks for a fairly simple machining job. Thought I?d go local rather than travel far for trusted sources. Should have known better!
Unfortunately Vince any good stuff costs a lot, eg Carillos, but you get what you pay for. The only thing I can save on is labour.

Marzocchi Stradas. May as well put in a piece of solid steel. Had them on the Le Mans, even the Ikon replacements feel better.

Don't think I've ever heard a good word said about them either. The SF1 I worked on had them and they were shocking  :D

When they're not leaking they're rupturing your spleen!

The concept of changing the spring rate hadn't made it to your part of the world?

I did exactly that. Threw the fuckers in the bin and put on Ikons. They were going in the bin anyway as it was found that the mounting ring on the left hand shock had around 1/3 of its circumference missing when the rear end was pulled off the bike so that the leaking rear crankshaft seal could be replaced. Just one of the many unpleasant surprises that came with the bike, now all fixed. All combined turned a reasonably priced purchase into an expensive exercise in repairing a death trap on wheels.
 
Had a shocker of a ride on Sunday, we went up The Bells Line of Road and even the new 2 lane bits were unpleasant, cer forks on the 3c kicking off bumps and it one point shimmying across the road on multiple bumps. So today I went back to 15wt fork oil at 140mm.
My experiment at using 180mm didnt appear to work, dampers were covered with oil but not compliant at all at the higher level. With the new oil, it feels very compliant bouncing the bike. We will see next ride.
 
Awwww I missed this thread...😗

The new tubes on my Ceriani have improved life.

Have been playing around with Sportsvalve rebound and I can dial out all the bounce but it's a bit harsh whichever way I go.

So as the springs seem short (theres a six inch spacer pipe to get to the top of the tube) and only two washers as preload adjustment (plus the bottom of the caps), I've added another couple just to see if it takes the spring into a working range that is better.


 
Mine is the same except its got 5 washers to get to a good sag distance of 35ish mm. That's with a 9.5 spring. Me at 125kg as well. We can not compare valve adjustments obviously, mines a Race Tech and yours in that NZ one.
 
BTW it was bloody windy in places where you suddenly appear on an open ridgeline, maybe that was some of the instability.
 
After servicing the Marzos on the Motodd and drilling an extra hole in the Racetech valves, set the original silver spring at 3 turns, 150mm air gap and took out a 15mm preload spacer and using 15wt oil the front end has been transformed. Think I might even play with the WP rear shock now, probably room for improvement after using the same setting for 34 years!!!
I don't really fuck with settings, I just ride the fuckers 8)

When I get things right the bike is like it's on rails. I was a little short on sag for road at 25mm at front, back same 25mm and isn't using more than 70% of spring travel.

The beauty with the Motodd frame, it doesn't matter what the settings are they always ride like on rails :D
If your ever in my neck of the woods you can try it out on my test track

Have you had a chance to try them out yet? My first impressions were very good, although I feel that they may be a tiny bit under-sprung for me but time will tell.
