Question about shifting into 1st gear.......
#141
I have several issues with this. No one uses techinque with any success in automotive drag racing, and the same principals apply. It also is only good for the start, everything else is equal from 2nd gear onward.
I'd like to see a comparison of 60fts with this technique. You'll end up in a taller gear earlier on the track too. The rate of acceleration will fall off more severely.
This technique entirely depends on clutch slippage to enable the bike to match the speed that the which means it's either not repeatable AND causes major reliability concerns. Basically like a higher stall torque converter.
A properly ridden bike starting in 1st gear will be in the powerband sooner, clutch fully engaged and accelerating at a higher rate than a massive clutch slip at 5500+ rpm.
It's a great way to either blow your clutch or wear it out immediately.

I admit I have never raced my harley. That would be like racing a ride on tractor, what would be the point. They're heavy and gutless, you'd be laughed at by the spectators. I have a stock harley, nothing impressive in any way power wise.
However, I'm standing by the technique. Maybe I shouldn't have mentioned the drag strip because it's not a repeatable method. Starting in first and rolling the throttle and running the gears would give you a more consistent ET. But if you're racing head to head, do a second gear start, rev the **** out of the engine, and ride the clutch to accelerate. Of course it will put strain and excessive wear on the clutch, but that's the price you'd pay to smoke your buddy in a race.

Well. What if ya do not want to or need to come to a full stop. Just a rolling stop. It is hard on the engine and transmission to pull in second gear from a almost stop. I guess what I am saying is it takes common sense and experience to know how to ride and how to shift. No knock on you. You will get the hang of it.

ok, first of all this is a tried and true method to get the holeshot everytime on a dirt bike.

Performing that technique on a street bike or car, let alone a Harley is asking for trouble and problems.
I see no issue with drag racing a Harley. Although slow for a bike, anything that runs 13s stock is respectable. There are far too many 15+ second FWD Hondas at the dragstrip with lousy drivers. Now they do get laughed at.

Btw, just for the hell of it, my buddy and I put smooth tires on our mx bikes and took them to the track one sunday. Back in those days our race track got chopped in half due to a new highway they were building. So we only had an 1/8 mile strip. We were running mid 8's in the eighth. Very respectable, we were eliminating a lot of really expensive very powerful cars. A dirt bike is light and hits top end about 3/4 down the eighth, which is about 85mph. They actually made a new rule as a result of me and my buddy. The car drivers had a protest after the event with the organizers and bitched that they were getting smoked by dirt bikes, so the made a new rule from that day forward. Bikes will be in a class of their own, never to race cars again. Then the next time we went we were racing the drag bikes, well, you can imagine how that went. They killed us.

I didn't know a stock harley would run in the 13s. Probably high 13s eh? I would have guessed low 15's. At any rate, a stock harley at the drags would be a groaner. Personally I think a bike should be in the 11's for some interest.

Do you remember your 60fts? I would be very curious.

This was a long time ago, I'm in my 50's now, this was back in my 20's. Back when I was young and crazy.
On one of those days when me and my buddy were there, we'd do our pass, eliminate a bike then loop around to the stands where our friends were sitting, with the cooler, have a beer. Well my buddy got to the semi's that day (he eliminated me, the bugger). He was half cut to say the least, the lights came down and he corked it a bit too much and his front wheel came up. And as I said earlier in this thread, you can't win a race by shutting off the throttle so he just went with it. Ran through all the gears with the front wheel in the air. Wheelied all the way down the eighth. Then, while he was going in 5th gear, right near the finish line he loops the bike. Talk about a major case of road rash. They hauled him away in the meat wagon. I ran down there and picked up his bike and loaded it on the tow truck, when we drove back past the fans there was a standing O, cheering and clapping, they thought it was me, I guess we were dressed similar. So I waved and bowed, my moment of fame. haha. Back in the good ol days.
