Some of the post below may not compute, since I was responding to Jerry's PM. Point is, the CB is much more compliant over semi bad roads now that lighter springs and different fork oil level have been done. I may still contact Ikon to determine if they can supply rear shock springs that are a notch or two lighter weight. I think a lot of my problem may be that I spent so much time on older BMWs over the past 30 years, that anything other than a lounge chair ride feels harsh to me. Anyway, the following is the latest update on my suspension issues.
-------------------------------------------------------------------------------------------
You're getting old?! WTH, Jerry, I'll hit 75 this coming January. I know the feeling. Although I still ride my 2008 Moto Guzzi 1200 Sport (love that bike!) she's a bit too top heavy and overall heavy for me, so it isn't my jump on for a 5 minute ride to the grocery store.
Well, the CB front end is much better after following your directions.
- we pulled the 1.00 spring, spacer, and RaceTech valve.
- I very carefully set the RaceTech valve preload to 3 turns in from zero preload.
- replaced the 20w fork oil with 10w Honda fork oil.
- after inserting RTV, set fork oil level 175mm below top of fork tubes.
- installed the .90 springs and spacers from Traxxion Dynamics.
Even with the Ikons on the rear, and the improvements to the forks, the CB isn't an R100R, but she is finally rideable (for me.) Before making any more changes, I think I'll try to get in some riding as we rapidly drift toward cold weather. The poor little Honda has only had 2200 miles put on the odometer since April of this year. Not fair to such a nice bike! I will admit, I'm having a somewhat difficult time adapting to the smoothness of the 4 cylinder DOHC engine, after so much saddle time on twins, whether Kaw W650, Triumph T100, or my long time ride, the BMW R100GS. I do like twins!
Jerry, once again, thanks for all your advice.
