FZS600 1998 BOGS/CUTS OUT FOR SPLIT SEC AT HIGH RPM

[sl2018]

hi all,


my fazer has started to bog or cut ( like flicking the energency switch quickly) but only at high rpms...11000/12000  (3rd gear +).... or say at 112+mph in 6th


i have slight blow on no3( manifold gasket) ..i have 4 on order......


my m8 tried to install a cheap alarm, turned out was fir a 2stroke,ncs v1( and blew ignition fuse, several times)
Could this of caused the rectifier or coil to have probs...(rectifier now letting too much voltage through to the ignition?).....it now has the correct alarm fitted  (one of thise  ncs v2 things)


other than that..... it only started at around  time of that install?


any ideas....i havent checked anything yet really..


thank you


before thjs bike ran sweet?

Could be many things:


Air leak
Old plugs, or not tightened correctly
Plug caps not screwed in tightly to HT Leads
Blocked air filter
TPS breaking down (do a quick check to see if it's in the correct position)
Dirt in carbs
Unbalanced carbs

I had similar a few months ago.. the bike would bog down when I tried to accelerate to overtake a car for example.


I traced it back to loose HT leads as darrsi has already suggested below.
