19 years it says!! I was on rec.sport.jetski in 90’s

WTB: looking for a 90-95 Yamaha Superjet Hull or 90-95 complete ski to build an other race boat with my son. I already have one just need one more. Midwest area preferred Message

Wanted To Buy: superjet hull. Bottom only can be a basket case. Any year 90-20. completely stripped is fine and preferred. broken, defoamed, soaked, doesn’t matter. this is not for a build. please Pm

Do you know if they are 135mm GPR or 133mm Kaw versions? Many cranks were made with either. Most over 77mm stroke got the GPR rods but can’t tell from your picture

Are those 135mm GPR size hot rods?

Thank you! Lots of fun! Bring on the outdoors

Wow what an end in 250! I forgot to put in my picks and boy did I get lucky. Everyone got close! Fun this year again

Difficult question. Depends on your detonation level and somewhat rpm. Personally I ran all oem bearings, ran 62t pins in the RD flat top pistons (Kawasakis forgings). I know some people were changing 20 hr mark but thats a little crazy if your still hold compression and no deto issues...

CPI has been making watercraft stuff forever. Lots of cast pipes came from CPI. All private label

That’s true. I was working with Calvin in 2011/12 (maybe late 2010 we started work) to create a triple cast Kawasaki 1200 for racing. He was taking the doo sledshop cylinder and machining the sides for 120mm centers, then we welded the castings together and the added the holes for the zxi cases...

lol. Possible Almost more than my checking too.

thats a BIG prop.....

Thanks for reminder! - need to spend my cash

Yes wow!

I have that catalogs. Carbon print on the outside Only seen one of those flex nozzles once ever
