 |
|
Hey all! I bought like I said, a 2001 SKM shifter kart by sguerzoni, not sure what model it is so I'll provide a few pictures so many I can get it identified. I found out that it's a cadet kart, but I'll be able to fit in it with a few adjustments, hope $370 was a good deal.
I also bought a 1990 CR80 motor for $20 so that was probably a good deal.
I live in the Willamette valley and I don't know of any races I can enter with an 80 since I am pretty "green".
I've been in contact with Phil Pfau and he has been a big help so far, any comments are welcomed!

It your in Oregon (according to my google search), your best bet is to find a local kart shop to work with. I would go to Pat's Acres to get started on what you need to get your kart running.

I could be incorrect, but it looks to me like this is a full size chassis, not a cadet. Although the picture from the rear, the right side seat mount tube is pretty far over to the left for a smaller seat.
Check out the Portland Karting Association website, they are probably your best bet for local karting info to get you going: http://portlandkarting.com/
Did you get a shift arm with the kart? It goes behind the steering wheel, on the right side of the steering column. Kinda of hard to tell but it looks like the mounting lugs are there.
And the left side pod appears to have been cut for a radiator. |

The left pod was in fact cut for a larger radiator, I have the stock CR80 radiator as of now, our temperature here is pretty mild would this be sufficient cooling?
I have lined up a shifter arm, the tabs are there and ready to be bolted up.
Phil Pfau is a long time racer and the owner of "world of karts" which is a karting shop here in Salem.
The right side seat mount is indeed to narrow to fit the seat I have currently so hopefully I can solve that with a few relief cuts and a bend and reweld.
Thanks for the comment! |

Also, I ordered a 26 tooth 50mm axle sprocket and a new brake rotor as the old one had a large chunk taken out.
All that is left is a motor mount, shifter arm, rear wheels, brake piston rebuild with new seals and a CDI for the motor.
The CR80 is all stock, would it behoove me to use aviation fuel? There is an airport fueling station four miles from my house so I could easily access fuel. I have been reading that premium pump gas may be OK but I'd prefer to run some thing that may be considered "safer" for detonation and so on. |

the smaller radiator should be fine. I have a 125 with a bigger radiator in the tri cities and it gets 90-100 and I still have tape on mine.

Cool thank you for the response, I figured maybe it would since a dirt bike utilized it, just had to make sure because karting and MX are two different animals.

Just run 93 |
Thank you, that makes it a little cheaper.. 
How about castor oil for the fuel mix? or will any name brand 2 stroke mix work? |

Do the brakes work? It looks like it has been sitting for some time, so it is best to go through the brakes completely. New seals at a minimum. Check carefully for any corrosion/pitting in the bores.

I am replacing the pistons seal, I bought a brand new rotor and I lightly sanded the piston bores. They look really good and the master cylinder pumps fluid well. |

The one big difference running a bike motor on a kart is the fuel tank is lower than the carburator. Hence the gravity feed a bike uses won't work to deliver fuel to the carb. You're going to have to put a pulse fitting in the cylinder and hook up a fuel pump. My suggestion is remove the cylinder and d/t the side of reed housing 1/8 npt and fit an 1/8" brass barbed fitting. The fuel pump will need a return line to the tank as the pump will flow more fuel than the carb can handle, and w/o a return the fuel pressure will blow fuel past the needle valve flooding the engine.
The other big difference between karts and bikes is you put alot more stress on the clutch and gearbox as on a bike you're powering a single ~4" wide tire on dirt vs. a kart with two 7" wide tires on pavement. It's worth pulling the side cover off the engine to inspect the clutch and put in stiffer clutch springs.
You'll only need avgas or race gas if you increase the compression ratio of the engine, pump gas and good oil and you'll be fine. |

Thank you Paul for the response!
I plan on using a Dellorto pump, just going to play around with the mounting to see what I like, and I'll have another look at the teeth on the gears and take a look at the clutch plates when I put a new gasket on the right side cover. |
