Going to NH you'll have to take a stop here in RI!

 

looks like weneed to set up an east coast run

 

 

Aye aye Cap'n - an East Coast run would be a good idea - maybe be make a thread
in road trips for it P.

Anyway back to the carb thing and diff gen's ......imo

each consecutive gen of carbs breathe slightly better and so by default
are progressively smoother running

The gen2 carbs I put on my 87 make the bike run a whole lot smoother
than the original carbs. I 'm sure I could mod either a gen1 or 2 bike
to take gen 3 carbs if I too, intake tubes and airbox being the only real
mods to be made for the latter

 

Can fuel injection be modded in at a reasonable cost?

 

hi, man ive had this1990cbr1000 for six weeks and have fixed so much its not even funny but thanks to everyone here ive done it myself ,except she runs so rich i cant take her out of the neighborhood,cleaned carbs,did a benchtop sync,changed plugs ,set mix.screws to 2 turns no dif.it tdles fine when you start off its ok then you accelerate bogs and wants to die forget about 4/5/6 gear pulled plugs ...black sooty looking ,cleaned them turned mix screws another 1/2 turn in noticed small diff.now at 1 it doesnt have an air filter i got one comin would that mess it up oh and checked the plugs n coil leads got good spark could it have wrong jets

 

he air filter will change the flow for sure 1 turn out seems really tight. Is there a chance you widened the jets when you cleaned them its easy to do accidentally. I would also try to do a real carb sync the bench sync is just to get it started so you can really dial them in.

 

Ha Ha . Seems I have the same problem after the bike has stood since last summer!

So , do you recommend checking the air/pilot screw?

Last year I fitted a Kn air filter (Ebay item no. 290745906884 )




and cleaned all the jets ( 120 and 38 ) and the float valve filter etc . The Bike ran and idled ok then , but not today .
Starts on choke and dies as soon as I open the throtle. I'm in the midle of cleaning the jets again as I found petrol (gas) deposits on the needles. They aint that bad but next time I'm going to drain the carbs before storing the CBR away for winter.

One thing, when the bike ran she didn't seem to want cruise well . Just felt something was holding it back. Unless it was pulling hard , like a quick overtake up a steephill. So I wondering if I need to rejet ?

Cheers
