I think maybe I spoke too soon about having 90 percent of the vibration out of my trike. Oh it's much better but still get some shakes around 60+. I took the front tires off the rims and scooped all that nasty pudding-like Ride-On tire sealer/balancer stuff out of the tires and then spin-balanced them. Both were out of balance. (I found out that I had put too much Ride-On in them and that too much can cause balance problems too). Rode her tonight and she's great up to almost 60 mph then still has some shakes in the front end. I am gonna put the recommended dose of 5 oz of Ride-On in each front tire in the hope it will smooth things out above 60. Just read the new comments from justincrediblem... you're lucky you spotted that rear tire wear before it blew out on you mid-ride--I'm sure that would ruin your day! You definitely shouldn't ride it until you get the new rear tire on. That rear tire must have really been out of balance to wear that badly on one side. And about the front end alignment... you definitely can't go just by the number of threads on the linkage. You need to take careful measurements (I used a straight edge along the outside edge of each front tire-once straight up and down and another front to back) from the top of each tire, as close as you can get to the bottom of each tire, and then again half way up front and back. All of these measurements should be dead on for best ride. I couldn't believe that mine was set right from the factory! Hope this helps ya get that thing back to smooth cruisin'.
Oh yeah, remember I mentioned how I lost power and had to pull to the side of the road? Well it has happened several more times and I now know that she's gettin' starved for fuel. It only happens on prolonged near full throttle. I put a new fuel filter in and filled the tank and on the first ride after it didn't happen. But it happened again tonight(not as bad though) and she's down to half a tank. So I'm thinking it's either an improperly set carburetor float and she's literally runnin' dry, or possibly a problem with the pick up in the fuel tank.(I'd love to see inside that tank to see just how and where the pick up is. It's strange to have the fuel line connection to the tank at the tallest highest point instead of the lowest point so there's got to be some kind of line or tube inside leading to the lowest point.) As I get less fuel in tank I'm hoping to be able to figure out which is the problem.(sure don't feel like removing the fuel tank OR the carb if I don't have to.) And speaking of fuel, now my fuel gauge is reading empty most of the time so I followed Alleyoops suggestions and checked the float but it wasn't filling with gas and sinking. I checked for voltage and resistance and both seemed good. So I banged on the dash near the fuel gauge and shook the trike side to side and low and behold the gauge started to work again. I tried wiggling wires and playing with connections but I couldn't get it NOT to work after that-figures! Oh well, a headache for another day!

Hey justincrediblem, just posted some info you might be interested in on general discussion/daddue11's cure for the blues thread. Made some tweaks and had a great ride with hardly any vibration. Hope it helps.

Taking the rear wheel off is not too bad if you have the needed metric tools. First you need to remove the muffler. The muffler is surprisingly heavy so remove the two long cap nuts securing the pipe to the engine first.



Now remove the three bolts holding the muffler to the swing arm saving the top one for last so the muffler is supported.



Remove the muffler then you can remove the two bolts holding the swing arm and the one bolt securing the brake line.



Now you can remove the shock absorber bolt and secure the shock up and out of the way. The fun part now is to remove the axle nut.



It's pretty tight so it helps to leave the tire on the ground with the weight of the trike on it or it's gonna want to spin as you try to remove the nut. Once you get the nut loose, put her back on the center stand and spin the nut off and remove the swing arm. Now the wheel will slide right off the axle shaft. Make sure to take note of the placement of all washers on the bolts you remove(caliper bolts have them and axle nut has one if I am remembering right). I took mine to a local cycle/scooter repair shop and had them spin balance it(dynamic balancing). I just added Ride On tire sealant(which is supposed to balance the wheels too) to the front tires. I rode her after and almost no vibration at 55 to 65 mph but kind of a shudder at 48. I might try adding a little more to each tire or I'll pull them off too and get them spin balanced. Oh yeah, and I think you'll like this...
here's MY Sunny Roadrunner 300 and HER big brother(LOL!!)



Hey, it's not a Raptor but it is a Ford! 2005 Ranger. She ain't no show truck but I'll bet she passes a lot more gas stations than that Raptor!

I've been enjoying riding the trike to work the last couple of days and now have about 120 miles on her. Coming home from work today though she gave me a scare... I had just gotten up to speed(55 mph) and suddenly she lost power(like my motorcycle does when the gas is low and you need to switch to reserve). I just filled her up the evening before so I knew the tank was full. Well I just pulled her to the side of the road and started thinking about what story I was gonna tell my wife to get her to come pick my Chinese reverse trike scooter obsessed arse up and after a bit of prolonged cranking she started up and ran normally. No other incident the rest of the way home. Water in the gas? Crap in the carb? Who knows, but I had some Seafoam that I have been meaning to add to the fuel in the truck so I put some in her tank and took her out for an evening ride and she ran great.
Well hope everyone is enjoying their trikes-I've got to get some shut eye.

Thanks Alleyoop

Thanks Alleyoop. Sorry about the pictures Daddue11. After I posted them I decided I didn't like the album they were in on Photobucket so I moved them and voila, they all went away. Finally figured out how to get them back so they are all there again. I kinda like her rugged naked look... And I agree, it's great that at least we three(with Sunny 300's) can share our findings and bounce ideas off each other. Hopefully others will join soon too.
And to Justincrediblem... taking her body off was no picnic but wasn't too bad. Took pictures as I went and followed the Big Guy's recommendation and as each new body panel came off, all of the seemingly 1000's of screws went into their own little ziplock bag taped to the panel. So of course I have these panels carefully placed all over downstairs in the house and the wife... well I digress. I think I might eventually post these pics with little arrows showing where the hardware is and where the hardware you don't need to bother with is. That issue you mentioned about your body lock(I am assuming you mean the "tilt lock" so she'll stand on her own without using the center stand) doesn't surprise me. My cable pulled out of the actuator lever on the handlebar while I was "showin' her off" to an admirer so I had to quickly go to the center stand. When everything is working right you need to "feel" for this lock by starting to pull on the lever while slowly rocking the trike back and forth until the pin seats into the hole in the frame bracket-then you can pull the lever the rest of the way to fully engage the lock. If you start yankin' on the lever without the pin being lined up you"re asking for trouble and something's gonna have to give... in my case the cable pulled out of the retainer at the handlebar(I would say this is probably the weakest link). Luckily my cable didn't break(still had the crimp ball at the end) and I was able to fix it by using two small washers(cutting one side to spread and slip them around the cable) then seating them in the handlebar retainer. The adjustment of the cable is down by the pin and if the body is on you will have to remove the windshield and front panel underneath(which gives you access to other goodies as well-lights, electrical connections, the radiator cap(of all places to hide the radiator cap!). While you're in there check to make sure that none of the wiring is dangling in or near the tilt lock pin or switches(like it was on mine)-that's an electrical nightmare waiting to happen. Well I'm getting long winded here and I'll be posting more later about all the "challenges" I've faced so far. I will mention one more thing, and something all Roadrunner 300 owners should check. My trike leaked gasoline from two places-a pinhole in the fitting for the fuel line(leaked like a flippin' geyser when I first started crankin' her over). The second leak was real subtle-a very slight odor of gas in the garage that I just figured was from my gas can that I usually keep in the shed. Well I stumbled on a couple of wet spots on the black plastic undercover on the bottom of the trike and sure enough-gas. Then I looked up to see where it was coming from and couldn't believe that there is a drain bolt on the bottom of the fuel tank and it wasn't tight enough. If her body had been on I never would have seen this but you can access it without removing any panels.
Guess that's enough for now-off to get rear wheel balanced tomorrow(hopefully the tire is not out of round!).

Nice rides! Hey, is that your trike on the Extreme Scooters site? Just got one myself and still gettin' her prepped. Did you stick with stock tires and do you have any vibration? I am sure glad that I pulled the body off and went over everything closely cause I found quite a few issues that would have turned bad if overlooked. Curious to know how your're making out with yours. Have fun with your toys!

Well I got my Sunny Roadrunner 300 and disrobed her of her body to do my Big Guy PDI. Still have some more work to do. Rode her once for about 5 minutes in the dark with no lights(not smart). I'll be posting pictures as soon as I figure that out and find some time. I'll share my experience and findings-good and bad(more good so far) soon too. Thanks to everyone on this forum for their information which has been invaluable so far(owner's manual is so bad it's funny). ;D
