i apreciate the information, i just was thinking if it was as easy as reaching down inside there and moving something to get more hp why not. i get excited and dont think things threw . you hear horsepower and then the mind goes blank and the drool starts to pour. i was watching espns show super bikes and the k14 suposedly outran the busa. powerhouse motorsports said that they were gonna give the busa more cc next years model. thanks again

 

Yea, the new ZX14 is a bad mother. I REALLY don't like it's looks but the power is supposed to be sick. As sick as it is, it's only fractionally faster than the busa. I think I'll take a busa just for it's strange looks. I'll take strange over plain any day.

 

the dealer said that they were gonna up the ccs next year, i cant imagine how it fast its gonna be then. 10,900 momma just wont say yes to that one, its to dangerous

 

Big D, I'll be there, Crackerjack will be there with his gixxer and hopefully Bud will be there with his gixxer- should be fun!!!

 

The busa will be a 1400 next year and they are upping the HP about 20 . just enough to stay on top and outrun the 1400 kawasaki again.

 

Hope you guys don't mind if a one builder pics the brain of another builder. Obviously the info/experience is critical.

I've also taken about 40 pics of Cardiac's Son's BusaDS. Now I just need to find a liter motor. Been looking, but have some in's that should pay off in the end.

One of the good questions would be.... if you think that a turbo MIGHT be in the future, do you have to build that into the design, or will it fit nicely under the cylinder/head shelf that is created by the angle? In other words, if I build it without the turbo... can it be added easily afterward?

Also, most look like they are moving the upper rear shock mount further back. Is this necessary to clear the motor for some reason? I would think that the stock placement would be fine as long as you had enough spring to combat the new/longer swing arm geometry.

 

This driving me crazy... I may have to sell the monster earlier than expected. I got a real bad case of the wants.

Major and Sonic, how long of a swinger did you guys go with?

 

I personally always mount the motor as far back in the frame as I can . the ideal place for the sprocket to be is on the swing arm pivot point but this obviously can't happen. mounting the motor further back will leave much needed room for the future turbo and help keep the chain from contacting the swing arm when the suspension is bottomed or topped out. it also looks cleaner when there is not a "large open area" behind the motor. I had a guy here this morning with a DS busa that he bought on ebay from someone back east. he told me he paid 10k for the bike and had to drive I believe 1500 miles each way to pick it up. I was SHOCKED when I saw it . really feel sorry for the guy. I had to bite my tongue and tried to be helpful but the bike is a total hack job. looks like they used fence pipe on one of the motor mounts. everything that could be done wrong was. the engine was placed in the frame wrong. the wirring was a nighmare , there were wide open vaccuum ports , the guy had made a weird fuel tank that only allowed room for air filters that were about the size you would run on a z50 honda. it had no instruments and even no temp gauge and the guy had reused the stock ds fan which is WAY to small for this application and WITHOUT a thermal switch so it overheated badly and boiled all the "water" out the first time the new owner test rode it. it was a mess. even had the complete stock giant street bike exhaust installed and the frame was routed way out around the stock header pipes. the builder didnt even bother to use all the motor mounts! I feel for the poor guy who bought it. he had no idea what he was doing when he bought this thing. it needs to be totally disassembled and completely redone. I strongly suggest that anyone who is considering a project like this do his research and inspect in person several other finished machines taking lots of pictures from all angles before attempting the conversion. I would also take my time and consider all possible errors that can occur before you mount each part. its not just simply placing a new engine in your frame and sprinkling it with pixie dust and then ride away. its a big complicated project . you will need to be a decent welder, have all the tools and equipment, have a good understanding of motorcyle electronics and above average motorcycle mechanical know how. I have seen some really poor conversion jobs that not only look like crap but are Dangerous and a mechanical nightmare plagued with constant break downs frame breaks and chain derailments. I guess what it all boils down to is , you may end up with a bunch of parts, a chopped up unuseable frame and nothing to ride.

I run a +10 ace fab arm

 

amen to what supersonic says- it really is a labor of love to build OR a big pain in the A$$$$$$$
+6 on mine and +8 on crackerjacks- at sea level(Dumont) mine is too short and wheelies like crazy at 5000 feet with 20 less HP it is more controllable and I like it.
Both swingers are ace Fab but he builds them weird and they really jack the tail end of the bike up unless you modify the shock frame mounts or the swinger shock mount- you'll see all the options at DS days.
