Project 110 Scrabler

[born2ride14]

ok maybe bout 1 month ago i bought a 2002 polaris 110 . it wa a 90 but he got a big bore kit.it has the following
oko 24mm carb
new reeds
new clutch
new clutch spring
mounts in front to make it 4in wider
rear wheel spacers
douglas blue lables all aroundnew durp front tires
new rear snowhogs
11in pit bike rear shock
koso racing pipe 110 big bore
ngk plug
renthal bars with pro-taper pad
simplified wireing
outer wears
some cheap air filter

maybe some other crap but we rode it around a few days and didnt run right. the guy we got it from was a redneck and did a half @$$ job on makin the new mount for the rear shock mount . so now i gotta re do that . this is what it looks like but i think im gonna sell hes to big for thisC:\Documents and Settings\jesse jr\My Documents\My Pictures\my quadsC:\Documents and Settings\jesse jr\My Documents\My Pictures\my quads

hope you didnt get screwed. you cant get 110cc with just a big bore. i have built many a 110.. for it to be 110cc it has to have a 54mm cylinder and a 48mm stroker crank. with the 48mm crank you have to machine the cases so the rod doesnt hit and the skirt of the piston has to be shaved so it dont hit the crank.

its realy a 107 but i no it has the hi comp 54mm head . but this guy didnt screw me he had all kinds of quads a 300ex an apex a rasptor 80 a 660r and another scrambler he aslo showed me all the stock parts from the quad but i told him keep the stuff for your other 90 and the frame went out to day to the painter the frame is gonna be black and the a arm s will be red . ill have it bck sunday

[markvette]

107 uses a 47mm stroke crank, no case cutting but the piston skirt still has to be shaved. with the stock swing arm and long shock you should not be able to keep the front end on the ground. built right a 107 is a very stout motor, my son raced a 107 for 2 years and a 110 for another year both built by me.

Mark

[born2ride14]

he had to make new mounts that pushed the skock back keep it at a stock height and also dude who cares bout the motor it runs great now i cleaned the carb and wow!!

[born2ride14]

the fenders i painted with KRYLON FUSION paint it came out ok then it didnt have a great shine( pic made it look shiney) so i took a scouring pad and they ar now flat black

[markvette]

ok Dude, just trying to help. seen a many a person buy something that turned out to be something totally different than what they were told it was. so have fun with it Dude.

[Livin4Real]

Can you repost some other pics since they didn't show up?

[born2ride14]

ya here

[born2ride14]

um can some one tell me how to get more than 1 pic on one post?

[born2ride14]

the frame went out this mornin and the will be black and the a arms will be red

[Livin4Real]

I was curious about the front end from your first pic, after seeing the head-on shot it looks like your camber and toe is off alot. Toe you can change but camber on a single arm your hosed. I think with widening the front an extra four inches your putting alot of leverage on the spindles with little stock shocks, that's when things start breaking.

[born2ride14]

the shocks were compressed down

hey mark..i hope you can help me..how do you figure CC?? would 54mm bore plus 45mm crank equal a 99cc engine??

Bore X Bore x .7854 X Stroke

54 x 54 x .7854 x 45 = 103cc

From what I understand if you start stroking them you have to make sure all your clearances are right you may have to trim piston skirts, machine cases, shim jugs, …………………. all kind of silly sh*t.

[jetski_dawg]

from what i was told this was a dinili engine with the 45mm crank.. the jug is 54mm and in pretty bad shape.. the bottom end is in pretty good shape..not sure what to do with it.. thanks for the help etondaddy

[markvette]

54 bore and 45 crank is 103.2 cc. there is no case cutting or piston trimming with a 45mm crank. the eary dinlis came stock with the 45mm crank. i like the 45mm crank and 50mm bore for a national motor. keeps you under 90 cc and seems to be a bit stronger than the 42mm crank 52mm cylinder thet most build for national motors

Mark

[etondaddy]

a 45 bore and a 45 crank is a 71.6cc not 103.2cc ;)

45 x 45 x .7854 x 45 = 71.6cc

a 50 bore and a 45 crank is a 88.4cc

50 x 50 x .7854 x 45 = 88.4cc

[markvette]

sorry just typed it wrong. i meant 54mm bore and it is 103.2cc

[markvette]

for future refrence


stroke bore cc
42 50 82.43
42 52 89.16
45 50 88.32
45 52 95.53
45 53 99.24
45 54 103.02
47 54 107.57
48 54 109.88


and i have seen one that was 122cc and a 133cc is in the works

10-4 buddy just messin with ya. ;) :D

[jetski_dawg]

we run at a local track where the competition all pretty much run cheater motors.. my daughters engine is the 42x 52 bore and is getting smoked ,ive got a 45mm dinli motor used that i want to build but not sure what to do on a shoe-string budget and make it bullit-proof and compeditive as possible

[markvette]

buy a 54mm cylinder, enlarge the exhaust port a bunch. put it together with your base and head gasket. measure squish, i like .022 to .032. should put you at about 180psi. if squish is more than what i suggested take the cylinder to a machine shop and have them shave what you need off to get the right squish. that will be a strong motor. also if you are not using the electric start take the stator out and cut the charging coils off. i use a saw zaw or portable band saw. takes a little drag off the motor. every little bit helps.

Mark

[jetski_dawg]

mark..how do you check the amount of squish?..do you use a plastigage??.. do you use the exhaust flange for a guide on how much to enlarge the exhaust port?? does the koso pipe cause too much back pressure on that large of a bore??..thanks for all your help

[markvette]

use solder to check the squish. bend it in a L shape, long enough to go from the spark plug hole and the edge of the piston. turn the motor over to compress the solder, measure the thickness with a set of digital calipers. i think i have a few cylinders laying around that i can take pics of the exhaust port and send to you.

Mark

[jetski_dawg]

thanks mark..you have a pm

[born2ride14]

i dont think anyone cares bout my build but here it is to day. i need to put new buushingsin the r a arm then she would be basicly done

[etondaddy]

What are you talking about...........we all care. It looks great. We all know what it takes to build one of this things.

[mxdad423]

Yep we deffinatley care, looks awsome, and like etondaddy said we all know what it takes to build one of these and not only make them look good but also make them run good, keep us all updated with some pics and posts......

[born2ride14]

ok then it time to tell u a little secret im 11 years old and rebuit this thing my self no help my dad is not realy in to quads wich kinda makes mad cause that polaris i mine i paid for it and everthing for it along with my 300ex and my blaster and my foreman 450 paid for em all and maintain them my self but we got issuses with the polaris its not runnin good at alli fouls plugs in like 5 seconds and its power band is kinda okward but as i said im 11 yr old boy who just like doin his thing so etondaddy and mx dad and markavette PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!

[born2ride14]

m

[markvette]

looks great. just tell me what kind of help you need and i will do all i can to help you.

[etondaddy]

Same her little buddy........... My son Kyle's eleven.

[born2ride14]

il make a vid when i get time

[mxdad423]

Yea same here little man, I will help out anytime, just ask. As far as the plug fouling thing it's probably a jetting issue, take out your plug and look at the bottom of it, with proper jetting it should be black on the outer edge (basically on the bottom of the threads) and the center sould be a choclate brown color. if the center is black that means it's burning too rich (wich is probably the case) wich would mean you need to go to a smaller main jet in the carb., if the plug is real white in the center that means it's burning too lean so you need to go to a larger main jet. Hope that helps you out, if your not sure about where the jets are or how to get to them let me know and I can explain it to you. Good Luck little man.......

[born2ride14]

well it does foul plug and have been through three in one day i think there 7s but i dont rember what i got at napa but and ways the power band is realy out of wak it will put puts until ur at bout 25mph then i runns like brand new that could be the jet but i dont think so ive been lookin round and i al ready know that the electrick ignition s go bad comenly so maby that but the guy i bout it from got a 110cc big bore kit (i talked it over with him)and he said it was sopousably instaled profesionaly any way i heard theres a balance shaft inside and u can put it in 2 ways 1 the right way and 2 the wrong way and when you put it in backward it will run but like crap soooooooo idk i don think its the ignotion i got a spark but the shaft and the jets so lets hear what u have to say

[mxdad423]

Well first thing is to look at the plug and see how it is burning, do that then let me know what it looks like and that will be a great place to start.

[markvette]

running bad on bottom end and then better on top sounds like to big a main. when it gets to the top it clears up a little and tries to run right. really need to know what size a carb is on it and what size main it has in it now. now on the 110. as i explained before there is no such thing as a 110 big bore also have to put a 48mm stroker crank in with a 54mm cylinder to get 110cc. anyway also there is no balancer in these engines so that is not the problem. sounds more like jetting or low compression. is it hard to start ? low compression will cause a motor to be hard to start, also will run bad at low rpm's but do better as the rpm's get higher. my son is 13 now and on a honda 300ex. we sold his 110cc stroker eton a few months back but i still build mini motors now and then. i have built more strokers than i can count.

[born2ride14]

ill do a compressoin test

[etondaddy]

Ya buddy lets make sure we’re not beating a dead horse here first and go from there.

[born2ride14]

anyone got and jets a can buy???????????

we would need more info before we could tell you if we have jets. is it a stock carb or has an aftermarket carb been put on. they use different jets. what size main is in it now so we know what sizes you will need. if you dont know which carb you have post some close up pictures of it and we may be able to figure out what it is. take the filter off to take the picture

[born2ride14]

its an oko 24mm carb it says it on the first page

[Nichols Atvs]

take out the main jet and read the number on it and you can tell us from there. Take out the plug what color is the center of it
when the plug is new its white, Is it black , brown ,tan or white still. On the bottom of the carb is a big nut unscrew it and to take the main out.

[born2ride14]

i thought i posted but i geuss not its a 115 main

[born2ride14]

o i forgot to ask if anybodywould be intrested in this quad for $1500 obo

[Nichols Atvs]

ok now ya need to read the plug see above post to tell us the color if its anything but tan you need to change the jet if its black then you need to go down on jet size untill its tan and you have it jetted if its something else youll have to take it to some one and a lot of people have taken the OKOs to a large body of water and thrown it into it. so it might not be so simple as this but give it a try and report back and buy a couple extra plugs you will need them untill you get it read .you need to ride it about 20 mintes to get a good reading then check plug .

[born2ride14]

black blak and black

[Nichols Atvs]

need to go down on the jet size
