GSXR400 Problems 1991 GK76A

[xXxKillDogxXx]

okay so i had a random misfire on number 4 not really that bothered probally just plugs so gonna get a new set and chuck them in and see what happens.

However on saturday i got it in the garage and did all the pilot screw seals and found carb one had a broken needle... and carb 4 didnt have a seal so that would explain the crappy idle, although it still wont idle brilliant but i think thats cause i need to put the mixture to 1.8 cause of my straight through can so ill be doing that asap.

Once thats completed the bike should be fine and then i can finally complete my last touches:

Red or maybe black screen (Double bubble)
Full red bolt kit (probolt)
K7 shock conversion ( really had the saggy rear end atm)
Stiffen up the front end its just to soft
remove the splitter from the front brake and run straight braided lines
braided rear brake line
Fit rgv vj21 wheels
fit a new set of tread possible diablo's or qualifiers

shouldnt take to long all depends on what i feel like really

Okay aparently theres blue smoke coming from the bike, however its only when i hit 6-8k on the revs or accerlerate really hard, i think its over fueling and they dont know wtf there talking about personally cause my breather isnt blocked it wouldnt be valve stem seals cause thats vacumme when you slow down and its no piston rings cause its not all the time or on idle. so what could it be?

Btw fitted the new tread got Dunlop Sportmax qualifiers for £180 fitted and balanced, didnt bother with the rgv rims just gonna polish mine soon instead.

Did you ever find out why number 3 cylinder wasn't firing mate? I've got a GSXR250 GJ73A with the EXACT same problem and I'm absolutely stumped??!!!

Cancel that.

Figured out one of my coils was poked.

Problem sorted.
