This is a copy of a reply to another post .......I brought over to this thread just incase someone reads this thread and did not see the other post.
Background: A Path To An Early Model Not Wobbling On Straights or in any turns/sweepers
Below is the chronological progression and results to finally making the Ole Dawgie handle with econo changes and finally.... no wobbles on straights or any turns. Keep in mind back then there was no internet proven turn key solutions to make a CBX handle ...not wobble...just an ole guy and ole bike trying to work all this out without spending alot of money and still ending up with a bike that looked like a CBX.
Dawige Handling History.....Timeframe: 1980 to 1990 or so
1. Adjusted air in forks at 1lb pressure increments. Still wobbled
2. Different weight fork oil starting at 5wt....in 2.5wt increments ....to 15wt. Still wobbled and brutal ride with heavier weight fork oil combinations.
3. Installed a steering damper. Still wobbled
4. Installed a fork brace. Still wobbled
5. Replace rear shocks with Koni adjustables. 15% better handling...still wobbled.
6. Watermellon on the gas tank at speed. No wobbles
7. Oversized front tire. Less wobbling......but it chewed 3" or so off the front fender tip at speed
8. Latest sport tires (12 sets or prior to item 10). Still wobbled
9. Gusset steering head, reinforced frame backbone, braced stock swing arm. Still wobbled
10. Complete 1100f 39mm front and 1100f back. No wobbles.
Note: Long ago an article in the Xpress stated that 35mm CBX tubes flexed 55% more than 39mm. Massive clue in my view.
Long trip....trial and error over ten plus years, but I finally got to the promised land an no weaving or wobbles at any speed or in the twisties.
For early models my recommendation now is to replace the current 35mm early model fork tubes with a late model forks and Race Tech Gold Valves....go from there. Use everything else you have on the front now.
I used to recommend 1100f full front because they were 39mm with all the adjustablity and they had anti-dive that really worked and had great success with this myself for 15 years or so. Howver a 39mm fork late forks with the Race Tech Gold Valve on the Dawgie installed this year is far superior to the 1100f front and is more compliant, less nose dive, less expensive, no technical or fitment issues and finally weighs less........plus the Gold Valve is adjustable.
Now you do just this you still end up with your single piston early model calipers and stock rotors, but getting better calipers on the front is a future step....and doing the 39mm and Gold Valve fix now will ensure you live long enough to actually start being worried about better front calipers to be added to this truly superior front fork setup.
Item 10 above was the only thing that resulted no wobbles, but this plus items 8 & 9....and finally the all important Race Tech Gold Valves yielded absolutely the best handling the Dawgie has ever had. 30 years of experimentation and econo parts....but I think it is done now....and the bike still looks like a CBX....and yes...it was well worth the wait.
At your option, you can proceed right to "Go" if you want ...come on out and ride the Ole Dawgie or ride it at a rally and see if this is what you are looking for in handling and absolutely no wobbles.
