Just curious, I weighed mine and it came in pretty light. Even with the total loss ignition AND stock tank. Thats gotta be 15lbs. right there. Anyway, just something to compare it to. I weighed it on a massive scale next door at the funiture warehouse. Who knows, damn scale could be off.

The first person to build a 300 lb FCB is going to kick some butt.
My 175 weighs 200- 205 lbs....surely a 350 can be built at 300 lbs. Seems like they would go pretty good at that weight.

I'd say you are reading a bit light.
Most of the guys I know that have weighed their SV350 bikes are in around 350-375 lbs.
What's the bike stock? Around 400?
Takes some doing to drop 100 lbs. You usually have to go the whole way, glass tank, fenders, seat, alloy wheels, no battery, lightweight exhaust, alloy rear sets, absolutely all unnecessary brackets etc removed, alloy clip on's, electronic tach, even the lightest tires you can find of suitable size. You have to get down right anal, you can say to yourself...oh this only saves 2 oz, it doesn't matter. Do that a few times and you are giving up a pound.
I've made chain adjusters for my bike, brake shoe cams are drilled hollow, I've made alloy brake rod adjusters...stuff you don't think matters but it adds up.
With FCB where you don't have to spend a ton on the engine, spend it on the chassis and get it as light as possible. Can get expensive though.
Build a FCB chassis within the rules but as light, and with as much attention as if you were building a MotoGP bike...and I think someone could end up with a quick, very good handling, fun to ride bike.

Since my bike weighs about 200 lbs. I'd give a 350 40 lbs extra for the engine, and 40 lbs extra for the chassis....that should make a 280-300 lb bike possible. Put on a rider under 200 lbs and you'd have a package that could run up front.

About 380 stock... Joe, put your parts in a box and weigh it. Tanner? Whats the lwsv weigh? TT? Beuller? Beuller?

I went back to the furniture spot to ask how acurate the scale is.... within 5 lbs or so they say. I weighed a 350 rolling chassis on my own bathroom style scale: stock frame, fork, shocks and wheels w/ headlight ears and bars at 105. Nothing chopped off...

Not to sound anerexic or anything. Just wanted to see what the range was. I know J'not that'D flys around the track with at least 2 batteries AND a PVL!

rosko-

i haven't had mine on a scale yet, nor have i really worked on weight yet. hell, i still have the alternator. after this winter, i should have the bike to it's proper starting point (after two seasons) and then can start getting fancy.

i pretty much finished assembling the bottom end last night. ive been doing all the rubber bits new. some of those "full rebuild" gasket kits suck. none of them have all of the gaskets. stupid. got the pistons in, clutch basket, oil pump and slinger and next week should be able to get the top end done. if were not doing chris' xr100 motor. so at that point i can toss everything i have so far on a scale. i have no wheels or shocks yet. so i probably wont bother til i have all that.

Looks like it could be 280...you have it pared down pretty good. Small pipes, alloy rims...looks like the tank is the only big savings left.
Have you ever run it like that? Should go pretty good with a healthy engine. You have a PVL on it....I don't see a battery.

Thanks, I just wanted to see what the range was. Seems to be hovering around 300. I have not seen anyones 350 set-up as light as it could be, could probably go as low as 260 +/- w/ stock frame, motor & carb. We'll never know for sure unless Johnny decides to take up FCB...
