| UUnlike the honda elite the honda vision does not have a washer welded into the exhaust pie, although there are restrictors in the muffler, they are impossible to get to, as they are right up in the pipe. The stock muffler on the honda vision is not aimed to produce performance, it is designed to displace the heat, clean the emmisions a bit and keep it quiet. To give the engine the power boost that it needs a leovinci muffler is best, they can ad 9 to 10 mph on your scooter. A lot of modern honda scooters come restricted via the cdi unit, to combat this you need to buy a new cdi unit, ( for most of the aftermarket parts described on this page visit this site ). |
| The honda vision scooter however is not restricted by the cdi unit. The only restrictor that you can modify is the one in the transmission, it is located behind the vario mechanism, iI believe it is marked with an R, fiddling with this is tricky, a very complicated transmission system to work on, and i dont think that it makes an amazing difference to the scooter, providng you follow some of the other instructions I list. To make the scooter accelerate faster heavier roller wieghts could be used in the transmission, again this is tricky, see taffspeed, or ve uk for details. |
| One of the easiest adjustments to make is the airfilter adjustment and carb adjustment. This adjustment will work on most non cdi restricted scooters. Remember everything that I list here is done at your own risk!! The air filter on the vision has been well designed to keep dirt and water out, one of the flaws is that it slows down air intake, which slows acceleration. To increase your acceleration and keep the air filter doing its job, you need to make a direct air flow to the element. If you look at the air filter underneath it, towards the back there is a rectangular hole, (this is where the air is sucked in), next take the cover off the air filter, you will see that the air has quite a journey to go on before it reachs the element, this would have been a good design, maybe it is, but i think that it does decrease speed, maybe if they had the different tunnels in it bigger it wouldnt slow it down as much. To combat the slow air intake process drill a small hole up from the rectangular hole in to the chamber where the element is, (I would take the element out first, just in case). Make sure that the hole is created by a drill bit about 2-3mm wide, no more, although this sounds small, you may cause the bike other damage if it is any bigger. After doing this put the element back in and put the cover back on. Now the fuel air mixture will be running lean so you will need to adjust the carb, I will finish this bit in a ew days time, come back soon. |
