Old school big power V2.0 "Black Cat"

[meathooker]

Got it on the snow finally. It wasn't perfect but for being a completely 1 off engine and not having a baseline for clutching and jetting it wasnt bad! There's still a lot left in it and so far so good! I have more work to do but at this point I'm really happy so far with the way it's working! This was a quick hit at the parking lot turning only 7900 rpm with my buddy who donated some of the parts for this build.

Yes it's loud and sounds absolutely awesome!

That sounds beautiful!!

Great write up and build thanks for sharing

Picked up a nice diamond S mesh hood, it clears the pipes perfectly almost like it was made for this setup, I really like the way it fits and functions.

Just a few tweaks over the summer and it's ready for next winter.

sweet build, question for you. Where do you source your headgaskets from. I have an old PSI 800 triple that i want to put back together and need headgaskets. Is Cometic the only guys or is there someone else that you use

Head gasket or base gasket?

Base gaskets in my case are based on the OEM 900 twin but made by cometic with different thicknesses and cut/matched to fit the porting of the case.

the head uses orings to seal in my setup. Depending on what exactly your engine is or what PSI used it could have a gasket or it could have orings.

If you need specific orings you can source the oring material from a place like mcmaster-carr in straight lengths cut to size and glue the ends together with a special adheasive.

Yeah its ready! Just a few clutching and jetting changes was all (leaner and more helix). I still need to figure out a headlight for it just in case.

Just waiting on snow for this build.

I have another PRO RMK im doing a ported 900 cat in and another watercraft 1200 swap so thats been taking up most of my time.

sometime in the future ill do another set of M1000 cylinders and put them on the 900 twin im doing now in the pro.

So did you end up putting these M1000 cylinders on a cut and welded case or one of D&D's custom cases?

This setup is on a cpc/dd cast case
