my scooter weighs just under 43kgs with a full load of fuel (1L) & coolant, assuming that i was making 20hp with my set-up we divide that with 43kgs then we get a 0,465hp/1kg power to weight ratio, now we compare this with a scooter having 24hp & weighs around 75kgs which i think is the lightest you can do on a Zip or Aerox scoot with stock frame we get 0,32hp/1kg power to weight ratio, a big difference you see?
now assuming you have NOS on your Zip & say it makes 30hp & it weighs 80kgs then you only have 0,375hp/1kg power to weight ratio, now assuming that i got lucky on my tuning & hit a 22hp output on my dragscooter which is very possible right now even with 28mm carb my power to weight will shoot up to 0,511hp which is near the CBR600RR with a 0,548hp/1kg power to weight ratio.
i have said this long ago "light makes might", while you guys concentrated on getting the most hp out of a small motor we have been doing the opposite by figuring out how to reduce weight of the whole scooter & when we have done it we then concentrated on getting the hp up on a decent level in order to be competitive against 95cc dragscooters, i have learned a lot from you guys when it comes to parts selection especially the pipe,you have absolutely helped me reduce my engine development time considerably & that i am very grateful, as for the frame we have learned a lot from the japanese where all out acceleration in 50m is the utmost importance.
we copied from their designs & changed some things b'coz we race 400m but we do know the importance of lightning quick acceleration as we have devoted most of time trying to get to the same times as those of the japanese dragscooters only without wheelie bars. now we can practically takeoff on our scooter under 100% throttle opening without fear of lifting the front wheel, the quicker you give the engine full throttle the lower the times you'll going to get, the more time you spend on feathering the throttle to prevent lifting the front wheel the more time it takes you to finish the same distance.
the scooter is so well set up that it spins the rear tire (TT91GP) with impunity, asphalt or concrete, it needs a good burnout just get more traction but we only do that when it's necessary, my rider has excellent throttle control that he can control tirespin by varying the rpm during takeoff, since we have been only testing the carb & rollers in the movie there never was a need to burnout the tires but if watch it again you can see a slight delay before the scooter shoots off & that's b'coz of tirespin, acceleration would have been quicker if the tire was hot & sticky.
i have been searching for a softer compound tire to replace the Dunlops that i use & sadly only Sava has those but i can get them when i really need them.
you can say that this scooter represents what it can do when you combine Dutch, Japanese & Filipino scootertuning techniques, sometimes you need to think outside the box to come up with something that works.
btw coming soon will be a 2F4R/C30 version of this scooter, it will be built on a similar platform to my dragscooter to take on the 95cc/125cc dragscooters, & yes i will post movies of it as well.
i remember what you guys said years ago if we had the same parts you have, well this is one of them.
