65983cobra Posted November 6, 2006 Report Posted November 6, 2006 Ok, now i want cheetas or cubs. But i can not find any info witch would be better. I dont race or anything just want more power for trails and just have the cool factor so i will not be going really extrem. the only differances i know of that the cheetahs have a power valve. What does that do and what are the benafits of having the power valve. Quote
badassbanshee479 Posted November 6, 2006 Report Posted November 6, 2006 the pwer valves on the big cheeta engines give the bike more low end. it is a valve that goes down into the exhaust port and it makes the exhaust port timing lower till you rev the bike up then the valve pulls back out of the port causeing the port timeing to raise and become a drag port in a way. the big cheeta would be better for trails but they are alot more expensive to build cause they use custom domes, reeds, intakes, and you have t have them ported, cases trenched pending on what stroke you go, and you have to cut the top case half cause most of the cheetas are big bores like 71-74mm cubs are nice because they use all the stock bashee stuff. If you are not building a drag bike why dont you just have a good builder port your stock jugs to fit your riding style. FAST charges 350.00 for a dune port. you will have about 1500-2000 in a cub, and I am gonna guess at about 2000-3000 in building a big cheeta Quote
decon Posted November 6, 2006 Report Posted November 6, 2006 (edited) ^he beat me to it, but ya... The powervalves give you low end while still keeping your mid-top. That why I say for the trails I would get the cheetahs over the cubs. A cheaper route would be a set of Rz350 Cylinders. Edited November 6, 2006 by dEcon Quote

What does that do and what are the benafits of having the power valve. theres plenty of info here on the site,about cubs,and cheetha cil,those 2 are drag motors,for top end.do you know what that means?and thay are in my opinion extreme.also be ready to spend at least 3 to 6 grand or even more.my 2 cents :beer: Quote

And why is it 3 to 6 grand? the cubs sell for $875.00 Quote
dajogejr Posted November 7, 2006 Report Posted November 7, 2006 So your are telling me these are only good for drag racing or dunes nothing else. And why is it 3 to 6 grand? the cubs sell for $875.00 That's cylinders them selves. Next is a head....cut domes. New pistons. Longer swingarm. Better clutch, longer chain, better tires..... true and welded crank if you don't buy a whole new crank all together. Although they'll run ok on regular pipes (a la T5's, FMF, etc.) they really are a top end cylinder, so....CPI pipes, Shearer Pipes.... Bigger carbs to compliment them...new intakes.... Bottom line is this, and it's been said a million times. A cheetah cub is not a trail worthy cylinder, all kinds of the wrong kind of power type for trails.... Yes, you can TRY and choke a cub down to do more, but ...in reality, it's a dune/drag style cylinder. And...yes, this is coming from experience.... :beer: Quote

Are there dunes in Detriot? I like to go fast too. If i wanted a all out trail bike i would have got a 4 stroke. Just wanted to know how it would run. And if it could be trail riden . How much power does you bike put down. I dont plan on leaving the fattys on there for good or the stock carbs . Just want to know if it will run and give me more power than i have know.Cant have it all at once, but Wish i could. Edited November 7, 2006 by 65983cobra Quote
dajogejr Posted November 7, 2006 Report Posted November 7, 2006 No....but there is a 300ft sand drag track 2 hours away, and Silver Lake sand dunes are about 4 to 4.5 hours away....and, yes, since I went cub....it's dune/drag only. I tried to keep mine tame, T5 pipes and stock carbs. yeah, it ran....and it put down 85 HP on a dyno....but, I didn't like it. Since then, I've gone RDZ/Shearer inframe pipes, had 35PWK carbs, and an all new ignition. If I had to guess...it was about 95HP, give or take. However, now I'm going closer to drag as well. Dunable override tranny, lockup clutch and putting it on alcohol.... I'm hoping to be around 105HP or so when done..... If you're going to put a cub motor together, you absolutely must have an override tranny, and it's a good idea to get a lockup clutch too. Stock Tranny and no lockup clutch, that bike won't shift. Trust me on that.... If you wanna be fast in trails, get a 4 stroke with a pipe, cam...air filter, jet it....and have fun all day long. If you wanna drag race and have fun in the dunes, stick to the banshee and some cubs. Trust me when I say this, once you go cub, forget about the trails. You'll need to set the bike up to get that power to the ground. Which means more tire and a longer swingarm...or you'll spend all day doing one of two things, frying tires or pointing skyward. In my opinion...it sounds like you need a good dune/play port on your stock cylinders....you're thinking about a cub....but it won't be happy with what you're trying to do!! Quote
locogato11283 Posted November 7, 2006 Report Posted November 7, 2006 i say NEITHER..have your stock cylinders woods or dune ported, buy some bigger carbs, new pipes, intakes and a head and bam, perfect trail bike...i wouldnt fuck with cubs or cheetahs for your application.. Quote

I aggree with these guys when it cones to the cub, not a trail bike. The Cheetah pv does really well on the trail. But it is overcall. And in the sand or drags it makes great power. In my oppinion it is a motor that you can use aywhere. It is expensive though. Your looking at the 4 grand range to do it right. Then of course you will never be done. Quote
r/atvshee Posted November 7, 2006 Report Posted November 7, 2006 like daj. said cubs are mainly set up for drags and dunes. Its not very fun riding tight trails with a swingarm longer than +6 from experience. I would probably get a dune port and maybe get a 2-1 carb setup, they help out alot on bottom end. I also think that adding stroke brings out more torque, if its true then probably a +4 stroker would help :shrug: Quote
Animalman294 Posted November 7, 2006 Report Posted November 7, 2006 Listen to what these guys are sayin', most of them have been doin' this for a while. You really need to decide what you are going to be doing with the bike, before you start putting money into it. And as stated above one thing leads to another and that leads to another and before you know it (if you plan on doing it right) you will have between $2000 and $4000 into either set-up..........Call Jeff @ FAST and he'll fill you in............ :beer: Quote

yamahaD4L Posted November 9, 2006 Report Posted November 9, 2006 id go with the T-5s forsure. i also thought about the cheeta but not in my price range. ill stick with the stock cylinders for now. Quote
