I'm not sure if anyone still has one of these reverse trikes, or if anybody cares, but for the last 4 years this 300cc hunk of junk has been a never ending source of frustration. One of the biggest sources of this frustration has been trying to get the "death shakes" out of this thing. At first they would only come in at low speeds(about 25 mph or less) and mostly when braking. Many wheel alignments later and no more low speed shakes but holy crap, if you ever needed to stop on a dime from highway speeds the whole front end wanted to jump in the next lane. The way the front end is designed, with the tie rods at a pretty steep angle instead of flat, when you get on the brakes hard and the front end squats, it actually toes in the front wheels a little and starts them shaking. The fix? A relatively cheap steering damper. Ok, there's actually quite a bit more to it than that, but the steering damper is what eliminates the shakes altogether. The whole fix? 1)Good quality tires properly balanced(I swear by Ride-On tire balancer and sealant). 2)Make sure the rear wheel doesn't have any side to side movement(the motor mount on these things sucks! I've had to have mine welded after it broke, and replaced all bushings with urethane). 3)Make sure everything in the front and rear suspension is tight. 4)Alignment, alignment, alignment! Getting this right is critical. The front wheels have to be parallel to each other and the rear wheel must be centered between the fronts. Also, to get it right it needs to be loaded with the same weight as when you're ridin'. I use two six foot I-beam style levels that I got cheap at Harbor Freight. Strap em to the outside of both front wheels then take measurments between them just behind the wheels and then at the very back. Levels are long enough that you can also measure the distance to the rear wheel. Once you've got the same measurements in front and rear and have the rear wheel centered between the two, your done. 5)Install an adjustable steering damper. I decided to go with a single damper centrally mounted to the bracket the tie rods are attached to. Definitely some red-neck engineering on my part with clamps and home-made brackets, but was able to get it mounted so that it has clearance even when she's leaned over. Dial in the amount of damping you need(just enough to control the shakes-too much makes the steering squirrelly), and then just sit back and wait for the next thing to break on this fine slice of scooterdom!

So I got the motor mount welded back together and reinforced by a friend from work(same guy that welded my steering shaft). I told him it didnt have to look pretty just make it solid. He got a length of square tubing and cut it in half, then welded it onto the motor mount. Thing is like a tank now. Only one problem. The urethane bushings took some heat and the upper ones started to melt a little and the lower long one turned to mush. Soooo, I'm waitin' for some more liquid urethane to arrive to redo the bottom one and I'll press out and replace the top one's too. Figures it's prime ridin' weather here in Pa...
Here's some pics of the Franken-mount.

So I'm ridin' the trike the other day and I kept gettin' a wiggle in the front end if I let off the gas quick. So I checked for "wag" from the rear wheel when I got home and sure enough lots of it. Figured it was just gonne be some loose motor mount nuts again but nooooo. The flippin' motor mount broke apart! What a piece of crap! Has anyone else had something like this happen? Here's a pic of the quality POS--

Anybody got an extra 20 grand they can lend me?

If plan comes together will have her back together this weekend. Got a new high quality u-joint on line and a guy at work is gonna cut the shaft off the old joint and weld it onto the new one. Then I've just gotta get the alignment right and she'll be trouble free... (did you actually buy that?)

Well I think I've found my problem. And thanks Cyborg for makin' me check the steering shaft and joints for play 'cause once I get goin' into something(and especially if I start gettin' frustrated), I sometimes can't see the forest for the trees. So sure, I've gotta redo the wheel alignment but before anything else I locked the handlebars straight and checked for play in the steering...





No, I wasn't workin' on the ceiling, stupid video is upside down and couldn't figure out how to flip it on photobucket. But as you can see I'v got a lot of play in the steering. Turns out it's the lower steering shaft u-joint where all the slop is.





Sooooo, I guess I'm gonna have to get another one from Sunny unless someone knows of an aftermarket source for a higher quality one.
Figures something would go wrong after I finally got the fuel gauge workin' and she was near trouble free.
