Don't let the similar look of a Classic and Super Streak fool you. The Classic is not at all related to a Super Streak. Classic is a BAM B18/19 variant which has also been marketed as Quest/Phantom/Venom/Vantage/Optimus/Summit/Trail to name a few. Losttourist hasn't been on the forum since Jan 28 2016 so he is unlikely to answer... but he does have a good post on the subject.

Super Streak is a magnum springer. It is a massive brute with power like a RWS460 or BAM B28; heck it may be a BAM B28.

:drinkers:

LOL! If it's a fastest wins, do your mods, and on the day of the shoot get the lightest pellet you can (usually the lead-free), and smear it with oil or vaseline. Both will give you an instant kick in FPS. The oil trick will stink up your barrel, but if it's only a few shots it's worth a try to get that edge.

Full power piston is 5.91" long. Reduced power is longer by at least 1/2". Don't. Remember exact length. Full power spring has 36 coils. Wire is .121" in diameter. Believe Quest 1000 piston will fit, if you have long piston. Quest piston # is B18-04-100A.

but how a longer piston is reducing the power? i mean the riffle wong crank the springer further unless the cocking is done at a closer point to the front aint it?

A longer piston gives a shorter stroke and less spring compression. So less air is compressed to lower pressure. So lower velocity.

The cocking slot is longer on longer piston so when you break the barrel it moves down further before it engages back of slot. When you finish cocking stroke barrel is in same position as a short piston stroke but the front of th piston is closer to the transfer port.

Sorry. Been a while since I worked on this so bad memory. Cocking slot is not longer. Longer piston latches in trigger sooner and the barrel stops a a different angle. You can actually cut a long piston down to short piston length. You then have to make a new hole for trigger to catch in.

Sell it. A piston and spring kit your looking at like 57 + taxes and shipping. For 109 you can get a Vantage 1000 fps.

Did you even check if its got a long or short piston in it? Because if its a short piston, its only a 18$ spring to upgrade.

The Super Streak is a different gun, a B22, so only the trigger assy is interchangeable. The Classic is a generic Crosman B18 coil spring with what appears to be a Trail Hardwood stock. So you can use whatever other B18 Crosman parts for it.
So being a .22 you no doubt have the 170/175mm piston, the full power is 150mm which is ~$35CA from Gravel Agency.
The full power spring is ~35-36 coils and ~.122" wire. The next size down is .118 wire, so check yours. A new spring is ~$13CA.
You can cut you piston down to 150 if you want to save the $, which is what I'd do. I posted the details on the site here somewhere, but if you can't find it I'll post again or send it to you.
Someone mentioned the nitro conversion which is pretty easy to do (posted that too). And the poster is not crazy, it is in fact harder to shoot than the coil despite what the mfg claims. It can be calmed down with mods and if he/anyone wants I can go into more detail.
Poor accuracy is usually the barrels fault, but could also be the scope, the shooter, other parts of the gun or all the above. Have details on that too, which I can send to whomever wants it, just write me at chevota at hotmail, say what gun you have, what your goal is and I'll send info along with lots of other useful performance info.
