#209160 FL_rider (User) Junior Boarder Posts: 166 Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   I just put Cobra Speedster Slashdown on my 07 RS just over a week ago. I love the look and the sound. Saturday, I was our riding 2 up and twice I scraped the tip of the lower pipe. Each time it was an unusual dip in the road while in a right turn. I am thinking if I adjust the pre-load on the rear suspension that it might help. My question is this. I want to harden the suspension correct? Which is, according to the owner's manual requires increasing distance "A" to 2.03. Is there anything I need to know before doing this? Should I try this first or go the route of buying Baron's 930 lbs. spring?   Logged     Last Edit: 2009/07/06 10:44 By FL_rider.     The administrator has disabled public write access. #209165 RoadieFF (Moderator) Moderator Posts: 2591 Re:Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   With the pre load at it's max you may find you still scrape, the Roadies suspension isn't the most stout. A sure cure would be a heavier spring, wouldn't hurt to try adjusting first though.   Logged       The administrator has disabled public write access. #209168 FL_rider (User) Junior Boarder Posts: 166 Re:Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   Thanks for the input RoadieFF... I see that you are near my old stomping grounds... I lived in Richmond until 1994...   Logged     Last Edit: 2009/07/06 11:09 By FL_rider.     The administrator has disabled public write access. #209172 RoadieFF (Moderator) Moderator Posts: 2591 Re:Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   Just an hour or so down 64, several hours during the summer with the beach traffic.   Logged       The administrator has disabled public write access. #209180 Mr Cancilla (User) Are ya kidd'in me! Gold Boarder Posts: 764 Re:Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   What you need to do is what I did and you won't scrape any more! First, I would still go with a new spring, but I'd go with the progressive. Second, I slotted the holes in the mounting bracket for the pipes so I could cheat a little on the positioning. If you push them all the way up (stock bracket) they are approximately level, but when you sit on the bike they lower and give you less clearance. With the slotted bracket holes, you can push the pipes up a little, so when you sit on the bike they are now level. Haven't scraped since!   Logged     My Album   The administrator has disabled public write access. #209193 FL_rider (User) Junior Boarder Posts: 166 Re:Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   Mr Cancilla wrote: What you need to do is what I did and you won't scrape any more!

And as for the slotting of the mounting bracket, are you referring the point where the muffler attaches to the bracket supplied by Cobra? I would prefer not to have to take off the pipes. I spent 3 hours putting these on at a friends house, who for all purposes, has an automotive workshop in the backyard. Although the second time around should take less time. Could it be that changing the spring would be enough? There is one other option ... tell my wife she can't ride anymore but that would be dangerous   Logged       The administrator has disabled public write access. #209220 Mr Cancilla (User) Are ya kidd'in me!

The one I have is approx. 800-1200lbs. Its wound tighter at one end than the other. Basically it is self adjusting to the load. Spring For the exhaust, you can remove that black bracket WITHOUT removing the pipes. Just loosen the 4 head bolts at the motor so the pipes can pivot. The top hole on the front of the bracket is left alone. That will be your pivot point. The other 3 holes will have to be slotted at the bottom right. Actually, the bottom (front) at 3 o'clock, bottom (rear)at 4 o'clock and top (rear) at 5 o'clock. Take your time. Just look at the bracket and visualize how it's pivoting and you'll understand what I'm talking about.   Logged     Last Edit: 2009/07/06 14:10 By Mr Cancilla.   My Album   The administrator has disabled public write access. #209246 Crusierbob (User) Platinum Boarder Posts: 1234 Re:Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   I have the same pipes and found that when I took my girlfriend out for a ride the first time the pipes scraped. I cranked up the pre load to near max and the issue is 99% gone. We can still scrape, but I can only remember once since I hardened the suspension.   Logged       The administrator has disabled public write access. #209334 rivergod (User) Senior Boarder Posts: 258 Re:Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   yeah mine scrape also if i'm in a lean and hit a dip they will scrap especially when 2 up   Logged       The administrator has disabled public write access. #209376 FL_rider (User) Junior Boarder Posts: 166 Re:Cobra Speedster Slashdowns scraping 2 Years, 7 Months ago   rivergod wrote: yeah mine scrape also if i'm in a lean and hit a dip they will scrap especially when 2 up RG, I am going to try stiffening the rear suspension as many have suggested. Hopefully that will do the trick. If not I may try to adjust the bracket or replace the spring. Decisions...decisions. How do you like the Cobras? Anything negative, other than scraping (which I believe Cobra could solve by moving the pipes a little closer to the frame)?   Logged       The administrator has disabled public write access.
