1990 FZR 600 starting problem in cold/wet
I bought a 1990 FZR 600 from a friend last March. He warned me that it had a history of starting problems on cold mornings or if it had been out in a cold rain. So a few times in the early spring it took a little effort to start it, then once it got warm i didnt have a single problem wit hthe bike over the summer.
Now I'm back in Rochester New York and the bike has still been great until last week. It rained for 2 days last week and after the first night of rain I went out to see if the bike would have any problem starting in the morning. Started right up without a problem, I let it warm up and then turned it off. It sat for another 20 hours through some rain and the next day it would start at all.
Let it sit all day in the sun and tried to start it in the afternoon, it backfired a couple times. I tried with the choke and without. I tried with the throttle wide open to clear it when it flooded. Now Ive tried using starting fluid. Ive check spark at cyl 1 & 4, both fine. I heard maybe it would be because water got into the tank so I tried some dry gas, did nothing.
Basically, my friend tried spraying the coils with sealant, he even replaced one and tried it on both sides and it changed nothing. He said every fall it would just stop working and then in the spring when it got wamr it would be ok.
I know that was a long explanation, I just want to be complete. Any help would be greatly appreciated.
At this point my only ideas are check spark on 2 & 3, but i dont hear any cylinders firing. And to drain the tank and try with new gas.
