Bike idles fine with same temp exhaust and same amount of fumes/ colour smoke- settles down to a good idle once warm and I shut the choke off-
Put in 1st gear and off I go -pulls fine, shut off throttle to change into 2nd looses power and I roll to a stop - very hard to start if at all then if it does start top cylinder is not firing?

Bike-
std- no wire splice or GPS splice
No holes in air box or mods
exhaust STD and still runs oil pump.
I have just changed from Denso W27EMR-C plugs to NGK BR9ECM and a fresh lot of 98 octane fuel ssoooo it should run sweet right?
Try to give it some gas at idle some times and it is slow to return to idle, prefering to take it own sweet time to come from 3000? rpm down to 1250 (something that it also never did before)


Changed battery to a new one too- this makes it start 1st kick when cold but once it dies there is no coming back
pushing it home is not fun anymore (luck it stalls after 1st gear and not 3rd etc I would be alot further from home by then )

Anyone have a starting place?
I am just going to go and remove tank/ fairing to have a closer look at what is going on -check back with you soon



Cheers!
