Exhaust Gas Analyser

this is the one I have always wanted... although its $1000 for the kit

 

Hmmm $1,000....
that's almost another bike!

 

Then you're paying too much. I got two for that money!

 

Hi guys..not had any experience of the NGK one but looks like a good bit of kit..a lot better than some I've used over the years and paid more for lol..i might ask my own misses for a prezzy or two this christmas!! I shall start research now if its got datalogging 'under load' then i'm onboard..that's not far off having your own dyno!!! A few mates have these and think there good..Gunson G4125..bit primative and basic as there 'co' only....accuracy's not fantastic but its accurate to within half to one percent..not bad considering they retail here at about £100 new..not sure what that is in aus..but it should see the a/f ratio set pretty much bang on at whatever revs (jetting range or pilot circuit)..personally I use a crypton tuner (crypton 440 'cruise mate') hooked up to each exhaust downpipe so you can monitor and adjust each carb individually..the Suzuki's (GJ73a) i'm more often than not working on have the ports already designed into the standard downpipes for exactly this purpose ..its likely that all the 250 four cylinder bikes have them as without they cant be 'tuned' properly cylinder by cylinder and carb by carb..you guys will know more than me!!! My fireblade 919 with pretty much a straight through exhaust came without when I got it..so I drilled 4 holes in the downpipes, 'tapped' them and cut down four bolts to suit..instant success to the fueling issues it had!! Frankster, it needent cost a fortune m8, the crypton set me back £40 from a garage going into receivership..got it calibrated (gut wrenching £100 on top) and its pretty much bang on..so hunt around and it'll be the best investment you ever make!!!! Measures co,hc,co2, noX and o2, cylinder by cylinder set up at idle,1/4 half 3/4 and full throttle..then balance the carbs after completion and its pretty much job done..it comes into its own when experimenting with hotter/colder plugs, airbox alterations, porting, basically any modifications and helps pinpoint ring/sealing issues, vacuum problems and the like..with a bit of use it'll also help if you decide to start tampering with timing and 'slotting' the cams in search of 'a bit more' lol..every little helps ..think boydie on here will second me with your gsxr..its a different bike when set up properly..that'll go for pretty much all of the 250 4cyl's as there quite highly tuned as standard, you might get 5bhp from an exhaust/filter/jetting changes but you'll probably get 10bhp more just by setting up what you've got properly boss
