Need more UMPH! for my 185

[ULLOSE2]

I need a little info from you guys. I need a little more low end torque from my honda 185. I have been told I can just change the sprockets. :headbang:
I am not sure though which sprocket (front or rear or both) and with more teeth or less teeth on the sprockets.:shrug:
I have the stock size tires but I just bought 2 new dirt devils and they have a lot more grip and it tends to bog the 185 down. I am not concerned with top speed, I just mainly trail ride and hit any mud hole I can find.
Any information is appreciated.:thumbsup:

Make a small airbox mod (see the other post thats abotu a 200s in this section) and add a smaller rear sprocket. By adding a smaller rear, youll get better acceleration and lowend torque but your topend wont improve (but liek thats a big thing on a bike like this one-its not made for speed)

Good Luck!

ok 200x, i believe you have your sprockets backwards, if you add teeth to the rear, you will gain torque, and lower teeth will add speed, its the exact opposite for the front, the reason for this, is becuase the front sprocket turns faster than the rear, and with more teeth on the rear, it makes the front have to go around more times to equal the same amount of distance moved, increasing torque, but lowering speed, and the exact opposite if you add teeth.:doh: :doh:

[ATCRYDER]

hmmm, I did word that a little wrong:doh:

Smaller Rear sprocket=Less Topened & better acceleration
Larger Rearend= Better Topspeed and worse acceleration

I think you worded it backwards again. :D

if you add teeth to the REAR sprocket you will help your acceleration & torque at the expense of your top speed.

the airbox mod will make power but if you get in the mud it won't do you any good.

lol, Im off my game again today:doh: :bash: :bash: :fire: :fire: :lmao: :bs: :demon: :cool: :(

[ULLOSE2]

:headbang: Thanks for the information. I will start looking for a rear sprocket with at least 1 or 2 more teeth on it.:thumbsup:

from my experience, adding 2 teeth to the rear, is like subtracting one from the front, and just the opposite the other way. you will be able to tell a difference with adding 2, but i dont know how much torque you need, so you will have to play around with different sprokets till its right.

In some instances (185s may be one of them) where the ATV is actually geared to high from the factory. Lowering the final gear ratio may actually gain a little top end speed by allowing the ATV to build more revs and put it more into the powerband thus higher top speed. I am talking a very small increase.
What I am saying is don't be afraid to play with the gearing. Changing the front will make a difference quicker than changing the rear but you also have a whole lot less choices in size and may jump right past the ideal ratio. Changing the rear size can be done more incrementally but you run into a cost factor too.
Either way you will need to adjust your chain tension and may need to add or remove links in your chain to compensate.

Where would I start? I would start by pricing out everything and see which is the most economical and bump up the rear a couple teeth or down the front a tooth and try it. Make sure you ride it BEFORE you change and then directly after you change. Follow the same trail and the same hills and turns to verify gains and losses.

p.s. Maybe check your Dennis Kirk catalog in the chain and sprockets section. It usually tells you how many links your chain needs for a particular combination of front and rear sprockets.

Thanks for the input Ed, I am going to check out my catalog and see what my choices are.:lmao:

[200x_Basket]

why not try to find a complete 200x top end to put on it?

[200x_Basket]

i just tore down that 185s engine that i had on ebay that you emailed me about. it had beed bored out to a 200 and had a 200x piston in it. it also had the 200x cam and head. the previous owner said it was fast.

[ULLOSE2]

Man i hate it when money just does not grow on trees!:doh:
I am currently building a stroker motor for my 1970 C10 truck. All of my extra cash is going towards that right now.
And my 185 is still running right now. If you decide to hold onto it I will check back in a month or so to see if you still have it.:yup:

[200x_Basket]

well i used the top end, sorry.

[200x_Basket]

i dome so,e research today and i discovered that that was a 200s engine with a 200x top. it was a 185s cylinder bored to a 200.

[ChrisPerkins250r]

ive actually heard that a regular 200 or 185 engine with a 200x top end(like mine) has more power then a stock 200x motor... i raced a stock 200x, beat him, i rode his and mine felt like it has more power... his was all stock though and mine is bored out and has a filter and pipe.....

[Fuzzy]

Its not that the 200s/x setup has more power. It is beacuse the gears in the tranny are taller on the 185s/200s then a 200x is. So if you are racing a 83-85 200x you are going to beat them in a top speed race every time. If you are running a stock 200x 12/40 gear setup. But i dont think it could take a 86/87 200x with the six speed tranny. But i bet they are aweful close. I droped mine down to a 11/40 gear setup. To give it more low end power and make it feel more like a stock 200x. And it was just to fast with the 12/40 gears.

[200x_Basket]

well i have a spare 200s bottom and a spare 200x frame. maybe i will build it just to see.

[ULLOSE2]

Is there anything different from the 185 frame and the 200x frame? (that might be better)

[200x_Basket]

suspension!! i would put both engines in the same frame and run them at a 1/8th mile drag strip!!! i could swap the engines between rounds!!! :booty:

[ChrisPerkins250r]

most of the 185/200' have no suspension, a few te later ones have suspension in the front but never a back suspension that i remember, the frame is also ALOT diferent.... and heavier

[200x_Basket]

i wonder if you could put the tripple tree and forks form a 200x onto a s model???

[ChrisPerkins250r]

hmmmm good thought... unless 1 of the mounting tubes(either s or x) was longer or bigger around then i dont see why not

[Ed Grimly]

I did that MANY years ago to a ATC90.
ook the forks off a Trail 90 and the fit directly on. Felt like I was riding a chopper.
Turned a whole lot better though.

I would regear with the front sprocket smaller if I were you. I just changed out my klx 650 dirtbike sprockets both a tooth smaller in the front AND two teeth bigger on the back. changing just a tooth or two on the back will prob not give you big results. Also, usually the front sprockets are alot cheaper. I've gotten them for like five or six bucks before, where a back one costs at least double that.
