As a follow up to my ohlins Problems ,i decided to pop it into Steve Jordan to get it serviced and a new body fitted.
Well after a slow start due to the fact that the damper rod had a pit in it, it transpired thet ohlins changed the internal spec at some point.

So loads of other parts were required.
The end result was a bill of £303.23.
So if you have an Ohlins model DU3420. be warned that it COULD end up costing a fair bit more than expected. I'm sure Steve has done a great job and i'm not digging at him.
Will put it on the bike during the week.
