Hey guys, so I've checked as many post I can stomach & haven't found a definitive solution, so I'm reaching out to the community for help. I have a 1990 cbr600f that I got a few years back as a track bike project. It was last on the road in 2004. Everything seems to be in working order as I've gone over it a number of times. The issue that I've discovered is that it doesn't appear to have any upper head gasket or lower cylinder gasket. I haven't been able to find a kit or set for this old bike. Do any of you have or know where I can get one? I've check ebay, cosmetic, even a few local shops but to no avail. Can I make a head gasket & lower gasket? If so, what should I use? I've seen in the forum some warn against using RTV or some type of gasket in a tube as it won't work, seal, distribute heat...many reasons. Is that valid, can I use an RTV like substance, if so which one? Maybe a gasket material that I can cut out by hand? Any ideas otherwise this bike is getting parked again. Your help and wisdom is desperately in need. HELP, I so want to ride this bike this year

I am pretty sure the 87-90 CBR600f1 all used the same engine, i think 88-90 had internal engine work done to them to produce more hp but I don't think the engine it's self had changed, not 100 percent certaint tho, you can find 87 gasket kits on ebay. would confirm with other members first before buying gaskets

 

They're the same part numbers, Part #:12251-MN4-003 for the head gasket and Part #:12191-MN4-004 for the cylinder gasket.
