Best upgrades

Cuban1280 · 08-17-2017, 11:02 AM

I own 3 Tao Tao atvs. My personal one is the rhino 250. I ride it when time allows but have noticed it revs kinda high (even after adjusting). My goal is to get the most out of the bike. What is the best performance upgrades and websites to get them from? Any and all help is appreciated. Don't care about top end mph. I'm interested in climbing better and off the line. it seems to choke out almost on to steep of a climb but goes balls out on top end.

Thanks for any help.

Regearing is about the best thing you can do for low end. These things come "freeway ready", it seems. The links are posted here in the ATV forum somewhere. The rear sprocket is not cheap...but really makes the Rhino useable.

I also upgraded to the Mikuni VM26 with a 110 main and I think a 25 pilot jet. I'm at 3000'. I've since changed the air filter in the pic to an Uni.

Finally, I dumped the stock bazooka and put on an FMF Turbine Core 2.

Runs great and has functional gearing.

I saw some gears on a few sites but didn't know if they were really worth it. Thought about the exhaust but it looked pretty straight through. I'll def get some gears. As long as I don't go broke buying things the wife doesn't mind.

I second everything 2LZ said .. I have pretty much the same mods with the exception of the exhaust. Still have the stock one on. I use the same air filter as 2LZ but relocated to under the seat because I spend a lot of time in the water.

I hear you on the hill climbing issue with the Rhino in stock form. The Mikuni VM26 and sprockets mods will really make a huge difference.

Just ordered a new muffler and sprocket. They should be in by this weekend or beginning of next week. Thanks for the help. I'll also order a air filter. I might look into relocating the air filter but I don't submerge it much, unless I have to.

The carburetor will make the big difference. You should consider it.

Cuban1280 · 08-17-2017, 09:26 PM

Just added the carb to my wishlist. I was thinking of buying new smaller tires for more acceleration. The stock tires have decent bite but I want more for climbing.

Darth Racer · 08-17-2017, 10:20 PM

Stick to the sprockets for torque.. smaller tires equals less ground clearance which make get you stuck more.

The sprockets should do what you need... I go up a very steep grade with a heavy trailer in tow and have no issues with the sprocket and carb upgrade.

Cuban1280 · 08-18-2017, 06:25 AM

Wasn't even thinking of clearance being a issue with tires. I know when the gears come in I'm gonna put them on right away. I think my muffler comes in before the gears. ill post pics once its in.

Darth Racer · 08-18-2017, 08:08 AM

On the rear side a small amount clearance can mess with your brake disk and sprocket when going over rocks, ruts, and other debris.

Smaller tires are a last resort for torque I feel. I'm a little over 200 lbs and the trailer I tow is around 300+ lbs I'm doing steep hill climbs just fine with the mods I did.

Cuban1280 · 08-18-2017, 12:30 PM

I like the setup. Yeah I'll definetly be ordering the rear sprocket next week. the carb also. is the stock clutch decent compared to aftermarket? or should I get that replaced as well? I noticed after one hard day on trails it was screaming. idk if it getting wet was part of it.

Darth Racer · 08-18-2017, 02:36 PM

I haven't had any issue with the clutch but you might want to check you have it set to engage right on the handlebar. Make sure it has the full throw when you let the hand lever go. You don't want it partially grabbing that would give you some slipping.

Also make sure to use a good engine oil because you are dealing with a wet clutch. I use Rotella 15w/30 which was recommended here. The clutch should not have gotten wet with water. Only oil around it.

Cuban1280 · 08-18-2017, 02:49 PM

it's a softer clutch than what I'm used to. maybe it's me and not the bike. I did notice tho on whygostock.com that they in their disclosure mentioned I might have to modify my small sprocket due to the wholes being to small. I was wondering if it is a easy remedy?

Darth Racer · 08-18-2017, 02:57 PM

Yeah easy enough... I used a grinder wheel but a metal file will work too. If I remember right I had to use the file for final fitment. You only have to file away enough from the metal keeper to give enough clearance for the chain to go around.

You may have to get some Allen style socket cap bolts to at the hardware store if the heads/flats of your screws are too large of a diameter.

That's the reason why you cant go any smaller on the front sprocket.

Cuban1280 · 08-18-2017, 03:27 PM

Ok. I had an idea that's what I had to do but wasn't 100% sure. Easy enough. I've been reading a lot of the other post from previous yrs. a lot of useful information. Glad I found this forum. Def going to steal some of the ideas that I've read for my own.
