View Full Version : anyone into there bikes
right ive got a kx85 2000 model,just wanted to know if you can make them quicker,its all racetuned,but the powerbands ain that strong on it,might sound a daft question but can you make the powerband more powerful,take alot of effort top get the front wheel up,my mate has got a kx100 1998 model which is a animal,he said he would do a stright swap for mine,dont know if to keep mine and make it quicker
I still love you stu, no matter what you think of bikers.
But yeah, I agree some are absolute gaylords...

k85 are 2strok how long it been since it had new piston and rings as they wear a lot and lose most of there power. so new set wood do it some good if you have not had any replaced in a long time my kmx 125 went through a set every 3 month's

In a nutshell...keep the bike in the right rev range (i.e revving the nuts off it) and enjoy.
You can also get a powervalve too...lol

buy my 2003 cr125 instead ;) alloy frame etc and just fitted new bottom end bearings so running really well
Change the pistons/rings and put a set of boysen reeds in there
i know it aint the fastest thing,and yes alot of kids ride them,i got it next to nothing,its just been rebuilt aswell,i only got it as i had a bad accident years ago,when i was young being stupid on them,then sold everything,that was ten years ago,just wanna get back on them,so didnt want to jump straight in to the faster bikes,i do agree with whats been said
so what are powerbands then? lol

hiya m8 had motocross bikes all my life 2 strokes rely on there compression sounds to me if new rings are needed maybe topend rebuild... wiseco pistons are the way forward your kx 85 should be just as quick as the kx100... ive had 2 kx 80's and a kx 100 and the 80's are just as fun..... price of rebuild not to expensive
also what are powerbands?
I have rubber bands, is that the same?

powerbands just kicked in YO
get rid of the 2 stroke and get 140 pit bike four stroke. so much more fun and more easy to throw about..:thumb:
other wise just make sure every thing is correct ie plug and carb is clean...:thumb:
Danny s-p
24-09-10, 02:42 AM
keep the 2 stroke as it a good make and never get 140 pit bike four stroke. so much more stress and more easy to throw because they end up in bits ..:thumb:
other wise just make sure every thing is correct ie plug and carb is clean...:thumb: edited for the truth. really i have had 3 pit bike all 3 have fell apart. one sent it clutch out the casing at me :wtf:
so what are powerbands then? lol
lol the band in the RPM where the power is, As said like vtec or turbo, both are powerbands in cars, but in a 2 stroke crosser it's much more fun :)

POWER RANGER springs to mind lol
lmao.
As per danny-sp.
A kx 85, assuming its nikosil lined barrel, needs a piston, rings and small end bearing every 8 hours of hard useage (Racing etc) Being a tool in a streight line on a field is around 10 hours.
What oil are you running it on?
Is the bike raced?
Whats the compression like?
How many rebuilds has it had?
An 85 should lift the front wheel in 3rd;)
davidfox280585
24-09-10, 09:51 AM
if im correct on the 85 they usually have a dial on the airbox which alters the amount of air getting through to it which altered the power delivery but simple things to try is a new plug clean your air filter, then either a rebuild, try bending the reed block stops a little further out and make sure you have a good exhaust system as 2 strokes rely on back pressure
I'll have my zx6r b1 engine for sale soon if you wana shoe horn that into place pmsl...

i know its had one rebuild as my mate said,i think its nikosil lined barrel,its only had about 5 hours use thats with it run in aswell,gonna try another exhaust system for it see what that does,any good makes out there you recommend,aint got a clue about the compression,going out on it sunday will give it a little service on saturday,will ask my mate to get abit more info on it

FMF shorty is a good system for an 85 (had one on my cr)
That would lift the wheel in the first, 2nd and 3rd gears, however, it was geared down from the factory.
I would be asking serious questions to yourself, if its loosing power after 5 hours.
Clean the carb out.
DO NOT ALTER JETTING
and then check the exhaust for coking up etc.
Also, what oil?
If its cheap shat, this will be the route of the problem.
Also, does the bike tick over? A 2 stroke motox bike should never, ever tick over:thumb:

go for dep or fmf system. i had full dep system it give it a real tingy sound and power bad came in a lot sharper. so it was easer to put it on it back wheel

its comes up in first second and third,thats about it tho,the exhaust its okay as when he rebuilt it,he flushed it out aswell,will check the carb,ive got it ticking over,by adjusting the throttle on the lever or what ever you call it,oil wise aint got a clue whats in it

What do you mean what's in it?
If it's a kx, then you premix the oil.
And WTF do you expect from a bike made for people under 14?
cub 90 is super cool did a 8hour endurance race on one last february was a laugh around mondelo park but if ya want a buzz get a proper bike gixer 750 all the way 130mph+ wheelies will get your pulse racing

Adjust it back, so if you shut the throttle it dies.

Lack of oil, an they gum up like mad!

My uncle said his 1098 ducati will lift at 90, that's it.
No chance it will lift at 130!
However, you can hold a wheelie upto and past 130
depends on gearing and torque spread. i have seen a guy get a gixxer up at 120 ish at brunters...

tis about right that matt,im just on with buying a r1 and im not expecting more than that to be fair,must admiti must of hit 130 on back wheel off a crest on the blade with my mate on the back,
and would hit the rev limiter in 2nd gear on one wheel at 115mph it would come up in 3rd but only off a crest
you nust be a really good rider to get it to lift at 130 cos my fireblade would only at 90 on a crest:wtf: ,

wouldnt class myself brilliant or any thing but wheelies would be a strong piont pop the gixer up around 70 or 80 and keep it there for as long as desired years of practice and jimmy fire blade helped a bit to :thumb:

cos there not race tuned for constant flat out rippin

well ive got a gilera runner 125 2stroke with a mallossi MHR 172 kit and a lot more stuff thats always been rode flat out and has never missed a beat and ticks over perfectley
yea cos its made to its a scooter crossers are different they just fowl up if driven slow or tick over for a long time they need flat out and also power valves need to be open to keep things clear

get a pit bike boy
well i went out on the bike yesterday after i changed the spark plug,plus gave the carb a good clean out,also flushed the exhaust out aswell,the bike is so much better now,lifting up in 5th gear now,but was abit muddy where we went,sliding all over the place got well muddy lol,think it needs a new clutch as now and again you will have to rev it abit to get it going,but other than that a good day.got bloddy sore thighs

Yes.
Its a 2stroke, so burns all its oil.
Thus leaving carbon etc in the exhaust.

Scooters are for poofs.
And thats a fact.
I wouldnt class a Gilera runner as a highly tuned 2 stroke.
Its a road engine.

Scooters/Mopeds are what get people into bikes. They are also a good cheap form of transport

05-10-10, 04:39 PM
pete it not bs the big bell part of the system send vibration's back to to the bore that help the fuel and air swirl on top of the piston. so if so system carbon up less vibration's get to the bore give less swirl witch give you less ignition and crap performance. my mate cr 250 and my kmx 125 used to carbon up all the time and wood run like bag crap then they wood been clean out then they ran mint
so why do all 2 stroke scooters have a tick over and they dont funk up?
Because there not highly stroung racing machines with 30bhp are they!
I race ktms not 100% sure if they have the same setup as a ktm. when i changed the power vlave shaft seals i didnt set the gaps on the valve right made it ride like a turbo car with a broken turbo. this was done with the cylinder off so if it has had a rebuild it may have had the valve out and not put back right.

Don't believe me then, it wa only the problem with the bike in hand, and Danny agrees.
If you use proper oil then you will never have to clean out the exhaust.
I've built a couple of 125 engines, and the first thing I did to my ped was cut the exhaust up and clean it all out.
Also, It never took a hairdryer to get me into bikes, dad is a rocker, through and through.
No scooter tat alowed lol

Almost Danny, you have the basics.
The expansion chamber creates pulses, so when the piston exposes the inlet port there's a tiny backward pulse, stopping the charged mixture being thrown out after the charge is pulled into the barrel from the crank via the transfer ports.
It's hard to explain without pictures and diagrams.
lol
Good effort though Danny, you have an understanding which is more than most!
ive had different two stroke bikes over the years on road and off road and when not ridden hard they do fowl up handiest way to clean them out is to pop a small drop of petrol in and burn it out but with crossers if there not ridden hard they will choke up they are built for flat out all the time unless ya go 4 stroke and also i never started on scooters or any of my mates there just a bit twist and go for me
