Well These engines can rev up to 7000 RPM EASY!! with the Carb they have, it is an evil one too! But under a load im guessing they could push 5500 to 6000 without a problem. My honest opinion is to just keep the governor on it and adjust it for 4000 RPM, You will be plenty fast and have plenty of torque.

I am in need of a clutch for the 5hp, 1'' crank,but the only ones that I have found to fit it are only rated for 7hp,and I may build up my engine sometime.The cvts are nice but I would have to mod my frame to fit one.We had a 5hp kart in Pa that had a centrifugal clutch and that was kinda what I was trying to replicate here,but may need to go with a cvt.The kart will be used in flat areas,like gravel,pavement,and around the field and yard.What do you guys think I should do?

 

[solomon]

CVT is best, but a "Max Torque" Clutch wold be fine too

 

[kingquad2009]

How much hp can a max torque clutch andle compared to the cvt?Do you know offhand where I can get one for a 1'' crank?

 

[solomon]

yea, you can get one for a 1" crank, the cvt will hold up a lot longer and overall give you more power and torque. this is a great buy! HERE but if you have a 40/41 chain this is what you need HERE, idk where you would get a cvt though. CLUTCH RATED TO 8hp, but will work fine on at least 13hp IMO

 

[kingquad2009]

Sorry for dragging this post on,but how many cc's is the 8hp?I have heard 319cc and 400cc.Thanks

 

[solomon]

somewhere along that. The 8hp will eat alot of gas and have alot of low end torque. I think i have a 5hp crank lying around here that has a 3/4" pto on it. If you want to trade the carb on your 8hp, i will give u a 5hp 3/4" crankshaft.

 

[kingquad2009]

I need my carb on my 8hp,otherwise I would.

 

[solomon]

=P okay thanks anyhow, if your interested in the crank i did find it, its in good condition just make me an offer =)

 

[kingquad2009]

What do you want for it? What would it be to ship it to northern Arkansas,zip 72642?

 

[solomon]

Id flat rate it probably so no more than $11 to ship it. So hows $20 Total? i dont need the crank anymore. I think i have a cam, some lifters and the matching connecting rod to this crank. For $5 more you can have all that included.

 

[kingquad2009]

I will take them,but if I go this route I am going to buy a billet con rod and remove the governor.Would that work?I get paid next week,so pm me your address and I will let you know when I send out the money.

 

[solomon]

Of course a billet rod will work! If you buy a connecting rod also buy some valve springs! Then you can rev that motor good.

 

[kingquad2009]

Where can I get those?comp cams seemed t have a good deal on them.Whats the best way th remove the starter cluch and flywheel?My small engine book shows a special tool similar to a 4x4 hub socket but thi tool is hard to find.

 

[solomon]

I would get the Dual Springs Kit from Comp cams its like $40 out the door. Also the starter clutch tool is like $20, i just use a piece of wood and a hammer and tap it off. The crank i have doest use the starter clutch btw, it uses a nut and starter cup.

 

[kingquad2009]

If I take a pic of my crankshaft end can you tell me if it will work?

 

[solomon]

eaither you use a starter clutch (like you said you have) or you use a starter cup and nut, you can get the cup and the recoil for it online for under $45
