The cyclone feed increases the rate of fire on the 98 by using excess co2 to spin more balls into the chamber than is possible with a gravity hopper.
No, only a Tippmann A-5 comes with a cyclone feed standard. However a Cyclone can be purchased that will fit the 98 Custom.
No, the mounting screws are different, it will not fit the 98. There is a 98/USarmy cyclone feed made that will fit.
No, the screw set is off and there is holes for the cyclone feed.
No. the cyclone feed should tap into the gas line already built in for a response trigger. you should be fine.
No. Hoppers meant for the cyclone feed will only fit the cyclone feed.
Yes, as long as it has two holes for the banjo hoses.
It is cheaper to get the A5 then the 98 with Cyclone. They will be identical otherwise, except for looks.
If your 98 has a Cyclone Feed System, then it should work just fine. If you don't have one, you can buy the feed system and upgrade your marker. Relate link:
About an 1/8th of an inch.
No, cyclone feeds are only for Tippman markers, because they have a small port on the side that allows excess Co2 to flow from the valve, to power the cyclone feed.
The a5 is a better starter gun because for the price, you get a better gun and in truth, the 98 is a little out-dated these days. The a-5 does use up a lot of co2 due to the cyclone feed system.
The Tippmann A5 is internally identical to a 98, but comes with a cyclone feed which helps it feed balls faster. It also has a nicer looking body with a front cocking knob, removable fore-grip, and a tombstone air hose instead of threaded hose. The 98 (and A5 attachments) is a solid starter marker, used as the rental gun at most fields because of its incredible durability. It is also a staple beginner system, because of it easy upgrade-ability (especially the A5) and low maintenance requirements. It is cheaper to buy an A5 than a 98 with a cyclone feed (which would literally be the same thing)
