After having to rebuild my scoot I have had many different issues, but this is the worst.
The tripletree and shocks are not bent, there is no mechanical issue. The frame has the tripletree angled inwards at the bottom, the frame i took for parts had 16.5 inch long shocks, I am using 16 inch shocks on it now. When I stop or go fast my front wheel rubs against the frame. I had to cut the fairing behind the wheel because it was constantly rubbing the wheel.
I need to figure out what to do about this. I have been doing research and figure there are a few possible solutions, but I have little faith in all of them. I need about an inch or more of clearance when I am sitting on the scoot, especially with my girlfriend.
I've thought of putting pvc pipe in my shocks to compress the springs and possibly limit travel up the shocks.
I've thought of getting longer shocks but don't see any longer than 16.5 inches...
The last resort I could think of is to take a mallet or something to the frame to bend it to aim further outwards, but I highly doubt that would work and feel it would just cause issues too...
Nothing is bent or damaged with the frame I'm using, the old wheels that were on it looked slightly smaller, my current wheels are taller, the wheels that came with the frame are slightly shorter but also have wear marks as if they too may have been rubbing the fairing.
Has anyone tried rebuilding the front shocks with pit bike shocks and adding a bracket and support rod to the longer shocks to support them?

The forks should not move at all . my front tire is about 1/2 inch or less from the bottom of the front fairing. Its more like 1/4 inch from it. When I stop my tire doesn't hit the fairing at all . I weigh about 215 lbs , so you think with my weight and stopping all of a sudden , the front tire would hit the fairing, but it doesn't. Did you make sure everything was tight and no play anywhere ?

Yes, there's no play, but possibly a broken oil seal now on the left shock. Saw oil on it today. Going to dissasemble and inspect the inner workings of the shocks later when it dries up outside, add some CPVC spacers to the springs to make them stiffer to react to bumps and weight changes faster. When I put the old front shocks on the tree with the old front wheel it does not touch the fairing or frame at all, but the old shocks are rusted on the inside and filled with mud and well over a decade and some old. I would obviously use that if I felt it was safe, but it only has a drum brake and I do not trust drum front brakes, and I like my antilocking front disc brake. Everything is straight, nothing bent, nothing has any play, all SEEMS good till I stop hard or have a passenger and stop regularly. I have enough fork oil to do a few more changes so I may try and see how it is with new oil, and replace the seal I think may be bad with one from the old shocks, you can remove them without rendering them useless right? |

Front shocks can be disassembled , but he rear shocks are a little more difficult. Not sure if they can be completely disassembled like the front ? |

Rear isn't a problem with my yellow spring rear shock. Plenty of clearance in the back with or without passenger. Only the front is problematic. |

So I took apart the shocks, inspected all pieces, everything looks good except the oils seals are a little messed up and seem to be letting dirt in. I cleaned everything out put it all together, seemed good, no oil coming out at least. I plan to replace the oil seals asap or get new shocks. I then added half inch spacers I made out of CPVC pipe to the tops of the springs and put it all together and went for a ride.
It was like riding on air. There was so little vibration out of the front end and it responded very fast, it seemed to only bounce once before returning to riding height when hitting bumps. Much better than new!
I learned about the CPVC spacers from some old harley dude who used to work on shocks for bikes. He said do not use PVC because PVC will become soft from heat, CPVC withstands the heat and high pressure, as well as oil.
