Another, hopefully short, delay. I sent some 33 lbs/inch springs off to be tested by a Comet owner and he found the front end stiff. Yesterday I tested two of the new batch of these springs and found spring rates of 36 and 37 lbs/inch. I have been back to the manufacturers and they have checked their calculations and the spec of the springs is what they intended. So today they will make a pair of 30 lbs/inch springs and send them directly to the Comet owner for testing. A pain in the posterior as several packs had been made up but better to find out too soon rather than after people have them and are struggling to get the best out of them. More news in a few days.

I expect Norman that lbs/in for springs are a bit like quoted torque figures and letters to foreign girlfriends - something is lost in translation dont worry I would rather wait than fafff about when the sun is shining

Any Idea when you can send some of the kits my way, I'm getting a few constant calls from customers chomping at the bit............Cheers...........Greg.

It is the GCM on Sunday in Coventry and, if the 'Beast from the East' does not cause too much trouble when interacting with 'Emma, the Sexy Beast from the South' I will try to attend and bring various steering stem parts with me. I still do not have the modified dampers. A call to AVO two days ago told me that 'at least another week'. On another thread Hadronuk tells us that the delay is due to illness with some of the staff. So if you are going to be there, and if the weather conditions allow, I can let a few of you have what you have ordered, less the dampers. Contact me on enw07@btinternet .com or by PM here on the forum to let me know if you would like to pick some of your parts up. Please note that at this stage I cannot guarantee to be there due to weather conditions.

I might be able to get someone to collect my bits on Sunday.
did you manage to sort out the issues with the spring rates? and if so would you be able to take the springs as well as the steering stem/link assembly?

I think my Series C with a 19" front was approx. 10 mph fast at a true 70 mph. My 21" is spot on, based on a bicycle speedo I jury-rigged.

If the bicycle unit was right, a 19" reads 77 and an 18" reads 81 at a true 70, assuming similar tire aspect ratios, using circumference ratios.

The upside for me is bragging rights to fast riding speeds without the risk. :cool:
My experience is Running a19 front wheel gives optimistic speedo data. Re 18 inch wheels low profile tires are a must. example 110/80/18 on the rear.
