Mostly they want to, I'd say, sometimes they have to. Sometimes they are not revving that much really, it could sound like it to the unfamiliar because of the open design of the bike, & the way noise carries from an unclad design, or the fitted exhaust, that may no longer be regulation compliant or original spec.I have not had this revving a lot whilst stationary as a habit during my years of riding various machines, 50cc to 400cc, since 1977.I always wanted to be sympathetic to my ride, sometimes blipping the throttle, but alert and watchful of revs, never sustaining an extreme, so that my machine may serve me well, as long as I needed it.I have never had money to throw away as a result of stupidity in conduct, like may be seen at bravado gatherings & the like.High revs at standstill was discouraged as a practice in tutorial literature I was exposed to: noise, nuisance, heat build-up, wear & tear…mechanical or electrical problems were possible potential problems.I would say, however: It depends what the motorcyclist is on / operating. I'm sure we've all seen Motocross starts, where they rev up and dump the clutch on the green light, but even there, if you are out in your input to throttle and clutch, & you are not strongly in control, you may just have a bad, non competitive start, or find yourself on the ground, having flipped your bike, about to be run over…If they have / one has a good condition, more ordinary machine, the various settings of throttle, carb, EFI, brain boxes, as the case may be, should be such that it can idle sweetly for long periods, rain or shine, all seasons, such as might occur in tightly bunched city traffic, without need for additional rider/ mechanic, whoever's input like opening the throttle.I.t.o. the engine stresses point of view, standing in neutral and revving high, like 50% redline even very high, like almost redline revs, is more stress on crankshaft, other bits, than during a ride. On a cold engine start, it would accelerate the wear, even more. Some machines have a way of somehow limiting the revs to try contain the stresses.What I do is start up, push in choke almost straight away, let idle untouched about half a minute while I don my gloves, check my helmet and jacket, then mount, do a brief, like 10 second, slight opening of my throttle, to get extra warm-up before I engage 1st to go up our steep, curved driveway.Sometimes, during a ride, I may not have engaged my gear properly, like on a JAWA 638 350 twin 2-stroke I had for 14 years, with the resultant revs shooting up because there was no transmission engaged, but if all is well with everything, the engine can handle it fine.

Assuming you have a good example of such a vehicle, since a worn, out of tune version, perhaps running rich or lean, carboned up, or oily deposits in the exhaust et al, won’t run according to its full potential, & may even cease to run if pushed too hard.Hence I shall elaborate somewhat, just bear with me, there may be useful stuff I’m gonna tell you ahead…If you have a fair example to use of such a vehicle, you can, in the absence of proper data, get the necessary experience that tells you what you’re dealing with engine wise as you use it, like feel the character of the engine: does it pull happily at low revs? What happens when you wait longer before you change up? Does it increase in strength such that you would feel confident you could achieve the needed/desired pulling power and accelleration? Maybe it has quite an intense burst of speed as revs climb that you have to be prepared for in posture, & you might run out of terrain before it all peaks…? Or does it dislike high revs?What happens when the engine speeds up/slows down a lot? What does that mean for the ride/drive you want to take?A 2-stroke 3-wheeler has a different set up to a scooter or motorbike.The 3-wheeler is a luggage carrier, & the motorbike may be a commuter or motocross/sport type built to be competitive in a race, or a fun/thrilling ride.Look up the engine specs of the vehicles engine, especially peak torque at what rpm, & /or what km/h in the individual gears, & peak power at what rpm and km/h in the gears, and take into account any modifications like inlet system and/or exhaust upgrades that change the torque & power development for better, or worse.A slogger of an engine peak torques far earlier in the rev range, and often peak powers far earlier too. It also has far less KW than a sport engine.A sport engine may have less torque than the equivalent capacity slogger engine, but may have lots more KW. Compare a 3-wheeler 2-stroke of around 200cc with a motocross engine!Use the best 2-stroke oil you can get, make sure the premix is fresh and right (‘cause it changes if it’s been standing: the fuel evaporates, but the oil doesn’t, so old premixes, especially where the bike/cannister/fuel can was in the sun, may run rich and smokey), or that the autolube/2-stroke oil injection system is working well, & use the best gearbox oil, chainlube/other lubes as applicable to the vehicle.I had a JAWA 638 350cc twin. It was geared at 25km/h per 1000rpm in top. Thus at 100km/h around 4000rpm showed, which was around where it pulled well, and I had about 2000 revs before redline.Below around 3000 rpm there was less power. Top speed given was 120km/h, which was almost at 5000rpm.The emphasis with this engine was good low to medium rev power, with some comparitively mild excitement higher up, unlike many other 2-strokes that rev far higher to pull sufficiently well, or have a strong speedy performance state of tune.With just a change of cogs for the chain drive, a sidecar could be attached to the JAWA and the std single carb engine could manage a loaded all up weight of 500kg, & which would not have suited a high performance sport engine from another brand so well at all.As I had it, it had peak torque of about 33 N.m. at 4750r.p.m., & peak power of 17KW@5750 in it’s std road legal state of tune.(There was a derestricted version with altered intake and exhaust system that revved higher and topped out at around 135km/h, & there may have been race tuned versions for track use that did even better.Different designs, different states of tune may have different characteristics, one needs to find specific info, & think seriously before changing something just to get some extra thrills, or economy perhaps, since it may not run properly on the mod.To accelerate best, first warm up everything with a few km of use, then, if circumstances allow, keep the engine close to or between peak torque and peak power revs or speed. There you should notice most responsive, intense performance.One may, like with my JAWA premix design, also have to ride several km at a good pace to clear the bikes exhaust system of most of the residual oil which then allows proper through flow such that best performance, & little exhaust smoking is possible.Other bikes may have drain screws at the right point of the exhaust to allow occasional residual oil drainage, especially when still warm, after a ride, & then replace them again, which I think I remember seeing on my Yamaha MR50 years ago.Below peak torque their is less & less torque to accelerate away, & above peak power acceleration drops off too.It may be possible to keep the engine going reliably continuously up to about 75% of peak power revs, one would have to check with someone that knows that particular machine.It would also help to keep revs down to a safer say continuous 60% or 50% of peak power in very hot weather, or with a heavy load/up hills due to increased heat build up.I wish you enjoyment in finding out what you need to do, & safe thrills, no spills!

The “Rapture” doctrine has no basis in Scripture. It is totally made-up. Christians should all be aware: we will be here during the tribulation; anti-Christ will arise; and who the anti-Christ will be, as the Bible gives very clear clues. Only one power has always been against (anti)-God’s “Chosen”?God’s first Chosen was Abraham’s son through Sarah, Isaac, “Grandfather” of all Jews. Unfortunately, an interloper came along, Abraham’s illegitimate son, “Ishmael”, grandfather of all Arabs. Arabs have been “anti” Jew from the day Abraham’s true heir, Isaac, was born. The offspring of the one line will in the end, still be anti- the offspring of Messiah of the other line. To put it plainly, the anti-Christ will be whoever is ultimately chosen to hold the Caliphate, or be supreme ruler, uniting all Muslims, and he will rule from the Dome of the Rock; the mosque that now sits on top of the Temple Mount in Jerusalem, in what was once the Holy Place of Herod’s Temple, which Jesus referred to as “The Holy Place” in Matt. 24: 15.Daniel prophesied the scenario first, then Jesus did:“…they shall profane the sanctuary, even the fortress, and shall take away the continual burnt-offering, and they shall set up the abomination that maketh desolate.” ( Dan. 11: 31)“…from the time that the continual burnt-offering shall be taken away, and the abomination that maketh desolate set up, there shall be a thousand and two hundred and ninety days.” (Dan. 12:11) This was the interval between the destruction of the Temple by the Romans and the usurpation of the Temple Mount by Muslims.“…when you see the abomination of desolation spoken of by the prophet Daniel, standing in the holy place (let the reader understand), then let those who are in Judea flee to the mountains. (Matt. 24: 15, 16)The beginning of the fulfillment of this prophecy of Daniel, confirmed by Jesus, occurred in 638 C.E., when the Muslim Caliph Omar, entered Jerusalem with the Islamic Army dedicated to replacing worship of the God of Jacob and Israel, with the worship of Allah. The “Office” of the “Abomination that makes desolation” was set up as the Caliphate in Jerusalem at that time. Omar was the first Caliph, and the Muslim occupation of Jerusalem was a set-up for the beginning of the Tribulation.Twenty-six centuries later, now, there is no Caliph, but the Jihadists fervently proclaim they will continue to strive to compel all the world to worship Allah, and they WILL, establish a new Caliphate. The Caliph will be seated in Jesus’ Holy Place, on the Temple Mount, in the Mosque. That man will be Anti-Christ, a Muslim, hailed as a man of peace, a peace-maker, but instead a suppressor/oppressor.(2 Thess 2: 1, 3, 4) “Concerning the coming of the Lord… that day will not come until the man of lawlessness be revealed … and he sets himself up in God’s Temple proclaiming himself to be God.”After the Anti-Christ/Caliph has set himself up on the Temple Mount, after The Tribulation, Jesus will come and cast him into the lake of fire, together with his spokesman.2 Thess. 2: 8) “…then the lawless one will be revealed whom the Lord will destroy with the breath of His coming….” (Rev. 19: 11–20) “…. I saw a white horse, whose rider is named … the Word of God… King of Kings and Lord of Lords… then I saw the beast… and the false prophet thrown into the lake of fire….”
