Guest stimbert Posted October 25, 2010 Report Share Posted October 25, 2010 Is there any real way to determine if a cyl is a cub or super cub from the outside (sealed motor)... usually they put the big billet heads on them, and bigger head studs.. thats pretty much the only way you could tell mine apart.. once you get inside its a diff story. you could also tell by looking at the bottom of the cases, my 10 cub is still the cast. my 10 supercub was epoxy-to get that big ass crank in there.. but again, in my opinion there isnt a way to be 100% sure from the outside Quote Link to comment Share on other sites More sharing options...
shanYE west Posted October 25, 2010 Report Share Posted October 25, 2010 was the crank in the supercub a big pin? usually they only use epoxy for the big pin/120 rod cranks. Quote Link to comment Share on other sites More sharing options...
Guest stimbert Posted October 25, 2010 Report Share Posted October 25, 2010 (edited) was the crank in the supercub a big pin? usually they only use epoxy for the big pin/120 rod cranks. yes, it was dan hulls old turbo motor, it was as built as they get for a 10 lol.... i was just trying to give him ideas of what he could check.. but like i said it would be pretty difficult to guarantee anything from the outside Edited October 25, 2010 by stimbert Quote Link to comment Share on other sites More sharing options...

dajogejr Posted October 26, 2010 Report Share Posted October 26, 2010 Possibly remove a spark plug and look down the hole to see if you can see numbers on the pistons... You'd have to have a keen eye or a micrometer to measure the head stud locations otherwise... Quote Link to comment Share on other sites More sharing options...

shanYE west Posted October 26, 2010 Report Share Posted October 26, 2010 super cub and big cheetah have 6 bolts holding the reeds in small cubs have 4 thats incorrect... super cubs use standard banshee reed cages.. (4 bolt) Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted October 26, 2010 Report Share Posted October 26, 2010 what head is on it? a cool head and or a noss head on a super cub are easy to tell apart.... the two studs in the middle of the cylinders (the two closest studs) will share the same counter bore on the head... where as a standerd cub head all of the studs will have there own counter bores in the head..... i can take a pic of my super cub head when i get home.... its kinda hard to expain with no pic... this is a stock head/ cub head this is a super cub head.... see the difference?

stroking Posted October 27, 2010 Report Share Posted October 27, 2010 thats incorrect... super cubs use standard banshee reed cages.. (4 bolt) super cubs start at 72mm right well all the ones ive seen have 6 bolts holding the reeds 65-68mm cubs have 4 Quote Link to comment Share on other sites More sharing options...
shanYE west Posted October 27, 2010 Report Share Posted October 27, 2010 super cubs start at 72mm right well all the ones ive seen have 6 bolts holding the reeds 65-68mm cubs have 4 all super cubs (72 and 73mm) use standard banshee cages. (4 bolt) If you see 6 bolts.. its a cheetah or its been modified. Even after its been modded..its usually a CR125 reed.. which is still a 4 bolt design if i'm not mistaken http://cgi.ebay.com/ebaymotors/Banshee-472cc-72mm-Cheetah-Super-Cub-Cylinder-4mm-_W0QQcmdZViewItemQQhashZitem5192c371f9QQitemZ350354633209QQptZMotorsQ5fATVQ5fPartsQ5fAccessories Quote Link to comment Share on other sites More sharing options...
drap660 Posted October 27, 2010 Author Report Share Posted October 27, 2010 (edited) Thanks badass. That is a good way to tell the diff. I always carry a micrometer so I guess even if they have a customized head, I can measure the distance between those to head studs. And yes a supercub is 4 bolt intake generally 72mm. Chettah's (non cub) 73mm are 6 bolt intake Edited October 27, 2010 by drap660 Quote Link to comment Share on other sites More sharing options...

camatv Posted November 2, 2010 Report Share Posted November 2, 2010 cheetas use 250r reeds and started at 68mm originally and can go up to 75mm if i'm right. most are at the 73mm bore.. the cheeta's also use its own head that uses a std even spread stud spacing and is much better at holding the head on. they are also the only CP cylinders to use powervalves.. i also believe they were from 4 mill up to 16 or 18 mill crank and in triple form also... they were the first cylinder designed by CP industies and are a very cool top end.
