I can't stand the fact that I've missed so many beautiful fall days of riding but I am a little closer. The liquid polyurethane and the tube for the bolt sleeves finally arrived and I had a little spare time and motivation this weekend so this motor mount project is finally nearing completion.
I am really happy with the steel tube I ordered to replace all the old bushing sleeves. The originals had way too much slop but much tighter tolerance now. And on the long bolt side of the motor mount, instead of two short sleeves(one at both ends) and hollow between, the new sleeve runs from one end to the other surrounded by urethane the full length. The liquid urethane was easy to work with and hopefully will be durable(I'm still waiting for it to fully cure-directions say 70-90% cure in 2 days and 7 days for full cure). Here's some pics: just gotta press in the two top bushing sleeves and wait for cure... ;D





By the way I sent you a PM Daddue a while back-ya still out there?

I just had to share a pic of my new car... She's a 2014 Buick Lacrosse and my wife and I both fell in love with her on the test drive. Traded in the 2005 Nissan Murano we've been thinking about getting rid of and all I can say is "WOW!!! I LOVE THIS CAR!!!

Hey Alley, thanks for the input. No it's not only that one bumper, it's all three. They are all distorted and binding. I'm thinking of replacing them with some high temp o-rings. Oh, and of course I made more work for myself by overstretching that one spring I removed so now I have to replace them. I can't believe how hard it is to find replacement clutch springs for this thing! I don't want to order them from Sunny/Scooter Depot/whatever they're callin' themselves today, and almost all that I am finding are for 50cc to 150cc machines. Any suggestions for a source for clutch springs for a 300cc Yamaha clone engine?

So I took the variator and clutch off. Naturally I wasn't carefull to hold the variator together as I slid it off and the pulley's separated and all the rollers came out of their tracks... (LOL!) Ah, but I wanted to take it apart anyway to check the rollers. So far I haven't found any problem with the clutch. Was expecting to find a broken or weak pad spring but all appear ok. I haven't been able to crack it completely open yet 'cause I haven't been able to find a 46mm or 1 and 13/16 socket. Local auto parts stores top out at 1 and 3/4(a 16th too small!). I am thinking maybe a piece of brake pad got stuck somewhere and wasn't allowing one or more of the pad arms to retract. I say this because a couple of the pads had a bunch of extra pad material kinda squished out where they are bonded to the arm but I wasn't payin' attention when I first took the clutch bell off to see if any crap fell out. Arms don't seem to be binding either but once I get the thing apart I will know for sure. If you read this Alley, do you think that since I'm in there already I should just replace the clutch arm springs? I plan to replace the Contra spring with a stiffer one just to experiment(I know the possible downside) so I wouldn't want to go with stiffer arm spings. Everything worked great at first until approx 600 to 700 miles, then clutch started grabbing(rear wheel would spin and had a lot of resistance when on center stand no matter how low I brought the idle down). I'll post a picture once I take one of the clutch arm pads--it looks to me like one of the three is worn down lower but the tension of that arm spring feels the same as the others and it doesn't seem to be binding...

ENJOY!! That sounds like a great trip. That "case" you're securing, is that a case of beer?(LOL!). Be safe... ;D

Well he said it before and he was right. The root of almost all evils on the Sunny Roadrunner 300 MCD300-TKB reverse trike is the flipping motor mount. I've got just over 800 miles on mine now and these "death shakes" on deceleration have been getting progressively worse recently. So I plunged into denial and figured it must be "the alignment", or "the front suspension's loose again", or "the tire pressure's off". Denial. Pure and simple. I finally had the presence of mind to check for rear wheel "wag" while she was up on the center stand the other day and sure enough, she's waggin' like hell. 800 miles. And to add another kick in my but('cause I'm usually good at keepin' an eye on these things) the rear tire is just about bald only in the center tread. Oh sure, you can call it cheap Chinese tires, but if the tail's a waggin' it's gonna tear up tires. And someone correct me if I'm wrong but I got to thinkin' about that wag and why it only happens at lower speeds and then it dawned on me...the faster you go, the faster that rear wheel spins. And what happens when a wheel spins fast? It becomes a gyroscope and resists "the wag". Then as soon as you slow down to a certain speed(just under 25 mph) no more gyro and all bets are off. Daddue found this out the hard way months ago and is still trying to get his trike back on the road. Wish there was a way to make Sunny accountable for this obvious blunder of engineering. Oh yeah, I thought I came up with a great idea to fix this. Since this trike is obviously cloned from the Yamaha Morphous/Majesty I looked into buying a motor mount for one of those scooters(you never hear anyone with one of those scooters having these issues. Well, as you might have guessed, the mount is totally different on them . So now I'm looking for urethane press in bushings to hopefully fix this thing once and for all.(You think new bushings will bring my fuel gauge back to life? Or fix the sticking clutch? LOL! It'll never end!)

I enjoy my Roadrunner 300 RT but as you can see by my many posts I have had many issues to overcome and still have a few and she's a year old now! So the only way I can recommend this trike is if you're crazy like me, very mechanically inclined, like fixin' stuff, or have a very deep wallet!!! ;D
