40:1 is a leaner mix and i have tried 32:1 both act about the same.mas2de said:Are you sure its supposed to run 40:1 and not something a little leaner like 32:1?
julien_d said:If the bog is worse with the choke on, that would indicate a lean bog? No idle... clogged up pilot jet, and questionable main jet? However, you said you tried different jets. Were they new? Does it smoke a lot? White smoke? Any way it's dumping water in the cylinder through the head or base gasket?
200PSI? Seriously?

if you close the petcock gas and wait some time while the engine is running it will be better and the just run out of gas right?
no, no, no. if i am understanding correctly, you take the floats from the metal arm? that arm is hold by a simple axle to let the float go up and down while closing or open the valve...Badbowtie73 said:It has 2 floats and they are mounted on rods to where you have to remove some kind of epoxy on the ends to get them off.
whenfoxforks-ruled said:The black plug could be water from a leak in the cooling system into the combustion chamber. A leak down tester can help, and it will check the crank seal condition. The right side is good for spooge. You can not look at a float valve and assume its fine. You do not even have a guarantee by leaving the bowl off and pushing the floats up, that it will work correctly. Just replace it yearly, or when you are having screwy problems. And stay with oem parts, keep it simple, you do not need more variables like crappier parts. An 89, does it have a power jet also? And for pete's sake, dropping the oil ratio to 40 is effectively increased the amount of gas! You made it richer yet? Premium fuel, factory oil ratio, factory jetting, replace the float valve, have a leak down test done.
I guess this thing is gonna have to go to the shop. We went to a local shop today to get a float valve so i took ours in to match it up and they said there was no way that thats our problem and the valve we had was fine. I put it all back together and set the float again and its doing the same crap its been doing. I dont know what else to try other than split the case, do a complete rebuild and buy a carb for it. It would be my luck that wouldnt even take care of it :bang:
I just did my brass on my 89 cr-fiddy, I leaned em out 1 step, it seem to run a little crisper. I have a kehin on it so it was easy to change them out. Pull your plug, if it looks like a charcoal biquet its too rich, if it is white and blistered its too lean, if the center electrode is carmel then its jetted perfect!Hi did you solve the bogging down problem. Having identical problems with same outcomes ... the bike runs strong when partial turn off of fuel .. float valve etc all been done still no clean run.
Air cleaner element to replace next see if that alters anything
Thanks.
