110 racer

[TrikerR]

im in the process of building a little racer to compete in a local championship for minibikes...up to 150cc, so ive decided to use whats at hand, it should be fun.
anyway my 110 needs a new top end put in i was just wondering whats the largest the 110 jug can be bored out to. i know you in USA would think it strange to do this to a 110 but my reasons are

i want something custom
and that larger trikes are few and far between here in aus, when they do come up they are expensive

and what modifications would i have to do for this setup to work.i know bigger jets, but what size. anyway im going to give it a port and polish and put a new exhuast on it. ive already got some front suspension and am just needing some tripple trees,would anyone know how much they would cost to have made.and also what twist throttle could i use, and whats a good set of handlebars to go on here

anyway cheers guys

Good luck with your project.

If you can try to find a 125 and you'll have 15 more cc's then the 110. If I remeber correctly the biggest piston I could find is 2mm over and that make it about 115cc I believe. Unless you find a big bore kit.
Another option would be a 90cc, because I think they still make a big bore kit from them, not sure though.

Cobra make a exhaust from them.

The biggest top end that will bolt on would be from a honda 125m. There are a few aftermarket twist throttels out there, ones for a quad will work. As for jetting that is done last. There isn't a set # for the main jet because you would have changed so many things (top end, air filter, exhaust). The only way would be to run a few plug checks and then swap out a new jet and test again, or get a dial a jet (probably the easiest way).

There is a 125m cylinder on ebay.

I am 99% sure that the 125M cylinder will not work. I remember GreenHuman and maybe even Howdy responding to this same type of question by a different poster. I think that 118cc is as big as you can go with the stock sleeve(Although I dont see any 90 or 110 pistons listed anymore in the Wiseco catalog). Powroll and other 4 stroke specialists can stroke your crankshaft to go up to your 150cc limit if that is your goal. We aren't talking cheap here though.

[hondatrikesrule22]

I am in the process of building a 110 racer also. It isn't weird to mod a 110. :cool: Anyway, with the right combination of boring and stroking, you can reach 180cc if you wanted to. For increasing ccs, stroking is the way to go. You will notice a difference. Greenhuman said that a Honda cb 200 twin piston will work in the 110. It is only .5mm larger than the 110 piston, but it raises the compression greatly, thus more power.

If you want something totally radical, Get a xr 70 frame, and plastics, and buy my racing swingarm that was made for 110s with suspension. Then get some tripple clamps made.


As for the motor, there is a ton of things you can do to it. Here is a list...

Exhaust
Remove airbox and use a clamp on filter
Stoking the crank
CB 200 twin piston
Vented valve caps
Bigger carb.
Re-jet
Lightened valves
DID cam chain
port and polish
a 69' SL 90 cam

And the list goes on and on. These mods will give a 185s a run for its money.

For handlebars, I am running a set of 1980 110 handlebars. What year is your 110? Because on the earlier ones, the handlebar clamps were close together, and not just any set of bars will work. I am going to race circle track anyway,so I don't need a set of moto-x bars. It also helps keep the "sleeper" look. :twisted:

[TrikerR]

yea well mines a 1981 model. whats the cb200 twin piston, and im in oz so who would stroke the crank for me

[MTS]

hey hondatrikesrule..would the cb piston bore into a atc 90 sleve..and if not dose anyone know if a 110 cylender would fit on a 90 crank and bottem case??

[TrikerR]

and what is stroking. would these wheel spacers work on the 110 http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=2488805990&category=43983

[mywifeknowseverything]

A friend of mine owns a Bike shop....He has about 6 or 7 ATC 70's with the 110 motor in them....However, they are now I think 145's....Not sure what all he did to them but they just flat Scream....

[TrikerR]

ohhhh why didnt australians get into triking. it not fair. is anybody sure that the 125 head wont fit on the 110. if its not a direct fit what modifacations would i have to do to make it fit.

Curtis is correct, a few of us have tested this before and know the 125m top end will not bolt up to a 110 or 90 bottom end.

[TrikerR]

would a automotive engineer be able to stroke my crank. and would i be able to bore the 110 out to 125

[TrikerR]

does anyone know the specs on a set of 1981 250r tripple trees. ie overall width, steering stem size, fork tube holes size.

[hondatrikesrule22]

Hond_atc-The cb200 twin is a motorcycle I think. Its 2 cylinders, so that means that each piston is 100cc. It is slightly bigger than the stock 110 piston, but raises your compression. It will give you more power than boring it out.

MyTrikeSucks-First off, love your name! LOL I am not sure about the the piston fitting in the 90. You may have to get a bigger sleeve. Ask "greenhuman" . He built up all kinds of 110s. He had a ATC 310. lol He should be able to tell you anything you want to know.

Hond_atc-www.powroll.com Go to the tech section,and it will be a page titled "What the heck is a stroker".Give them a call. They would be able to make your crank a stroker. It would give you more power than just boring it out.

[bigred110]

Can anyone conform about the CB 200 piston?
I checked on the 200 and the bore is 55.5mm(about the same as a 125) the stroke is 41mm(about the same as a 70).

[MTS]

hey mywifeknowseerything could you find out what that guy did to them 110 motors...right down to the specs ?:D?? i might put a 110 or a 125m motor in my 90...but i need ideas to get even more power outa a 110...:)

[martyrsxblood]

heres a link to a cb 200 kit really cheap on ebay

[TrikerR]

powrol wouldnt stoke my crank if i live in aus, would they.

[TrikerR]

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=2489056371&category=43974

would this setup make my bike look like a chopper and is it worth it

Exhaust
Remove airbox and run a clamp-on filter
CB 200 piston OR bore it out
stroke the crank
vented valve caps
lightened valves re-jet
bigger carb.
DID cam chain
69' sl 90 cam
port and polish


You could add all of those mods to this. Get a xr 175 cylinder(and head?), and a sl 125 crank stroked to 60mm.It should give you around 310cc.My God that would be a sick 70. :twisted:

[MTS]

also btw where do you get the SL cams your talkin about..and lighter valves and the DID cam chain also the bigger carb where might you get thses:D?

[hondatrikesrule22]

Yes, it has been done.It was done in either dirtwheels or 3wheeling. GreenHuman had one. He said it had alot of power. He said, one time, he really cranked on the power, and the hubs spun and broke off inside the wheel.


The cam chain, you might be able to find at the D.I.D. website.

The sl90 cam is availible at your Honda dealer,or service honda.

There are places to have your valves lightened.

I am not sure about where to get the carb. .

[TrikerR]

does the xr 175 head and cyclinder bold up to the 110.

[Curtis-Tecate3]

Here are some goodies....
Maybe you can talk him into parting it out.

damn...310cc's out of a 110, i shoulda kept my old one,i think thats a lil past his 150cc limit tho ;) , did that need to run on high octane gas or anything or just pump gas

[hondatrikesrule22]

Yep, and you would still be able to bore and stroke it to 342ccs.With a motor like that, I would be finding someone else to pull start it for me. :twisted: I was telling him how these little motors can be made into bad-ass motors. I don't think it would require race gas, I would probably run Premium.

[TrikerR]

yea ive already asked him if he would sell me those parts seperate. if he says yes i offer him about 250USD

[hondatrikesrule22]

Sweet! You ought to ask him if an machining or anything was done, or if it bolts right up.

[TrikerR]

would some one be able to send a email to that guy with the nice 110 for sale and ask if he will sell the performance parts seperately and where abouts he got the speedo for it. because he seems to be ignoring me, i think.

Im guessing if thats the case, its a NO.

[TrikerR]

maybe but i dont think someone would be that rude...he just might not of got round to reading it or hid email might be screwin up.

[BIG BAD RED]

there is a company in china that is selling 200x engines that fit 70's...mart says hes got one on the way for his. you can try calling balards down in penrith over here in nsw he does alot of stroking and all that goodness. i chase up a number for you in a few minutes

[HaggLE]

XL175 doesnt bolt up. You have to weld the cases and redrill the studs etc etc...
