Is this silicone-based

Yes...if you look for Threebond products you'll find similar sealers and better information (Synthetic rubber/RTV/Silicone based) , Threebond 1104 is grey in color Like Yamabond 3 and has a 150deg. Celsius max temp, Threebond 1215 is also grey in color and has 250deg Celcius max temp...I believe Threebond makes the Yamabond 3 , it just gets private labeled...I use Yamabond 3/Threebond 1215 on all my engine cases since the 70s, works great...the Threebond brand may have a cost savings when compared to yamabond 3...both are kinda gooey to work, a Popsicle stick may help you spread it on mating surfaces prior to assembly...a little goes a long way...hth

Can I use on crank case on dirt bike.

I used the product on my Yamaha golf cart engine. It is for sealing a split case engine. Have not had any leakage. thx, John

Will this seal a split case of a 2000 Yamaha Roadstar 1600cc engine? full of power and heat.

Yes and I think it's the best sealant there is! I use it on air cooled split case vw's and it works awesome!

Can this be used on valve cover gaskets to help seal ?

yamabond is normally used in a metal to metal sealing application....like between sealing two engine cases together ( typical in motorsport applications)...for valve covers on American cars...I suggest Permatex "The Right Stuff" P/N 85224 ( about $22)...Amazon has it listed...most factory OEMs use this Permatex product for their valve cover sealing on V-8 and V-6 engines...hth
