I want a spree

want to buy an aluminum kit.

thanks,

I should have read through the entire thread (zx trans) before asking.

did anyone have "success" with using the bigger rukus front variator to get the top end back after putting on the bigger belt. I have read that people tried it but results were a little unclear.

dropped weights from 8.5grams to 8 grams all around. got my 52mph back ant at least its not reving out at the top anymore. I was reading the ZX trans mod earlier and it was saying something about getting a bigger belt so that it rides/sits HIGHER on the rear pulley (from a stop) restoring some low e...

does anyone know if the stock SYM DD50 boost ports are smaller or bigger than the AF16??

thanks for the input guys. I will try lighter weights, but i think its the small size of my engine thats limiting my top speed.

time to upgrade.....

thanks again.

So i was running stock gearing in my SYM dd50 (11 to 1) and I was topping out at around 52mph (reving out a little at the top end but getting there fairly quick). i have heard people getting to 60mph with the 9 to 1.

would the SYM DD50 block be closer to the AF16 or the AF18. i have read that the AF18 has bigger stock boost ports than the 16 among other slight differences.

thanks again for all the input.

thanks guys. yes its a new bore (about 600 miles on it) and yes i want to keep my stock airbox. I took out the plastic tab form the inside of the airbox but i havent drilled any holes or anything. I was running the stock pilot (38 I think) and i was running too lean. am i correct on assuming 12mm fo...

I have heard/read 12mm. can anyone confirm. also if it is 12mm what would be the largest main and pilot jet that i could run with t...
