i think I confused both your topics
That's OK, I got the gist :)
I run at the track. Replaced front and rear springs. Put Ohlins 30 cartridges in the front and Elka shock in the back. Huge different from stock. Have no clue to help stock set up as I got rid of it as soon as I could. Fast and stable in A and B group and I'm 71 years old.
Wow ! I have more respect for you than to any rider I have ever known. Riding a sport bike at 71 years of age is amazing.
I know a good suspension can make all the different, I hope I'll manage to do it someday soon...
Keep riding man, I think you'll inspire everyone who reads your post.
Anyway, thanks for all the help guys !
I actually managed to fix the problem buy servicing the front suspensions.
After it was done I managed to cut 3 second (!!) from my previous best lap time.
A month later I installed a rear Ohlins and 0.2 seconds were cut off again (and than a pretty fast low side).
Bottom line, the bike works OK now.
I had to fly 3 times to Europe in a 3 months period just to get it done but it is done.
I still have to put the correct spring on the Ohlins. I bought it from a friend with a 120 spring, my weight is 75kg so I think 90 or 105 spring will work better. not sure yet.
