Launching Tips?
I tried to search for this and came up empty handed – maybe I should be too embarrassed to ask. LOL
I just can’t seem to launch my Street Bob worth a damn. I don’t go around trying to do this all the time, but I can’t really seem to spin the tire on launch just for kicks either. Is this bike too heavy to be attempted to do that? I’m sure it’s not good for it to be stressing it like that.
As for a good launch as if say I were to race somebody. I launched it last weekend while out by myself and almost got flung off the back of the bike. Is there a trick to staying on the bike? Should I be clamping my knees tighter or what? Maybe that Street Bob seat just isn’t too hot for drag racing?

You can definitely smoke the tire or pull a wheely if you choose. Rev it to about 2 grand and just pop the clutch. If your tire is sticky hot, you'll raise the fromt end. Better be damn careful though. Also, if your motor is stock, I wouldn't recommend this at all. It's a great way to clock or scissor your flywheels...Not to mention what can happen to the rest of your motor, but the flywheel set-up is definitely a weak link. Better off slipping the clutch some and rolling on the throttle.

Yeah, I’m not trying to break anything…. Much less have it get away from me and drop it. I was just on some of what looked like really slick pavement last weekend and thought for sure I could peel out a little and I don’t think it peeled out much at all. I rocketed off fairly well though.
I was more interested in technique for a successful racing launch. I see people on here posting their quarter mile times a lot. I just don’t seem to have much luck with launching without being nearly thrown off the bike. Maybe that’s my inexperience? It’s just such a big bike. It’s probably best that I don’t experiment anymore with launching it. I think it’s probably the seat not being very well suited for quick launches.

If u watch some crotch rocket videos or even other drag race videos when u first launch they have it rev'd up a little bit for the launch after the have the tire nice and sticky, they then lean a bit forward to help not wheelie and leave their feet and legs out to the side *For some reason* then after however many feet they put them back on the pegs to be more arrow dynamic..but i wouldnt recommend doing that unless u wanna update ur clutch a little bit

I guess I haven't been on a stock Dyna for too long : ) You hang your legs out just in case the rear tires gets loose and squirrely...

rev engine up at its peak torque or just below and ride clutch as not to wheelie or spin too much. my streetbob when it a had a 103 would flip you off the back if you just dump the clutch with the revs up. the se 180 is a sticky tire, much better traction than the stocker. perfect lauch imo is the front wheel just skimming off the road or track. se spring on the stock clutch can handle over 100/100 easy.
