550 seca sprocket sizes

i have a 81 seca 550 that i have been trying to find something to do with since i have no paperwork on it and i decided to make it a drag bike to go out and have some fun, i have done some major engine mods and this little bike can hold its own pretty well, but at the end of the 1/4 mile im only at the tom of third gear, and i was wondering if anybody would know what size sprockets i would have to use to make the gears short enough to at least be in 5th maybe 6th at the 1/4, i am posting this for insight only, if your going to talk CR@P about how slow it is compared to newer bikes i don't care, i do it for the fun!!!!

 

what mods have you done so far i also have a seca 550 pm me or just wright i here

 

molded seat, lowered suspension, wider rear tire&rim 130-90-16, port and polish head, custom welded and ground camshafts, happily revs to 14k+,custom bars, rear fender choped, tail brake and turn signals of a 02 R6, custom made exhaust( straight pipe) carbs have been redone and rejetted pilots are 4 sizes bigger and mains are 3, right now i am waiting on the new carb boots and throttle cable to get here

 

how much did you port out the intake or exhaust or both what did you do to the cams whats the top speed and how much did you spend and do you got pics

 

i will have pics soon as the project is nearing an end, i took it out the other day but the spedo only goes 85 by adding rpm's tp where the spedo stoped i would guess somewhere around 120ish at the top of fifth, i didn't want to shift into sixth cause the bike was "poping" due to the cracked carb boots, i have a buddy who owns brc off road, its a shop in yuba city where he does abunch of engine work to 4x4 vehicles and i don't know how much he ported them out i just know that when i stick my finger in either one intake or exhause it is smooth as silk, and he told me that he took the camshafts and welded some sort of hardended steel on the lobes then ground them down to shape with a micrometer, the thing will lope at idle like a hot rod and take off at 3k like a rocket

 

oh i forgot to tell youh ow much i spent, right now i am sitting at about 400, i got the bike for free so i lucked out there but most of the work i had done to it was him ust messin around cause he was bored at his shop

 

"if your going to talk CR@P about how slow it is compared to newer bikes i don't care, i do it for the fun!!!!!"
I think you're confusing us with "YouTube" and the like, dominated by 14 year olds that know even less than nothing about what they speak.
Most of the members here know that you cant compare our almost 30 year old bikes to modern technology. That being said, I have a fairly modded Gixxer at my disposal, yet 80-90% of the time when I want to ride, I grab the keys for the XJ!

 

yea i had another forum on here (xj550r seca crotch rocket project), and it got butchered by idiots talking down to my bike because i called it a "crotch rocket"
