Newbie ( lots of questions)

Howdy all,
I've been running a Rotax kart the last couple of years in Spokane, but my dad and I do have a older Swiss hutless with a KT-100S on it. I've noticed that in the tricities you guys have managed to create quite a large Yamaha class again, and I'm wondering what I need to do to make this thing legal to run with y'all. So far this is what I've come up with that it needs, please let me know your thoughts.
Air box (currently only has K&N filter on it)

Different Pipe ( has a C2 welded on it??)

Engine has 787 stamped on the side of it. (What does that mean? I do know it is a legal engine tho, as it was built by PITTS, and was legal when my dad got it originally.)

So guys am i missing anything obvious that it could possibly need to be legal?? Thanks for your time.

The pipe you have would have to be changed to a 4 hole can or the RLV 7403 or the HPV 3 pipe. As for the engine, the 787 is a legal barrel. If you run the can, you can run 6.00 rear tires and if you run the pipe, you can run the 7.10 rears. Class weight is 350.

Hope this helps
Corey

Corey,

I appreciate your response, thats the kind of information i was looking for! Also one last question, running a Wet clutch (horstman DXL) is legal correct?? Thanks

Reny.

You can run wet or dry clutch. No direct drive with the RLV 3 or the HPV 3 pipe.
