MY LXR 180cc

there is no doubt you are destroying your clutch plates.. what clutch springs are you using?

only inconsistency would be the clutch springs

we have never destroyed plates, we only use bel ray thumper oil
when looking at the plates there in minimal skuffing/wear
just standard 155z clutches

 

[sean01]

well something doesnt add up.

cause standard clutches slip like no tomorow

we have never had any problems with the plates , only the ring gear shearing teeth off, since running bel ray oil we havnt had any problems with clutch to date.

would you agree oil quality can make a differeance ?

 

[sean01]

to an extent.

i just know for a fact they would be slipping.. and since you do second gear starts with crazy gearing it wouldnt matter what oil you use

yeah i reckon your right, i will take everything on board that you have said.

i am still learning how to set the bike up for my needs eg. crazy gearing, boost bottles and so on. and what not to do

thanks for everones comments on the bike and recomandations on tune ups

 

[winky34]

hey everyone,
i had the LXR on the dyno yesterday,
here is the resault sheet and a video
what do you guys reckon of these figures ?
also had the bike dyno tuned and where the carby settings were, he said they were good

[wogtaz ryder]

not bad , is that with a knobby tyre?

 

[winky34]

ah no just a motard, is that a good figure for a motard tyre ? and in your opinon what hp difference would a knobby compared to a motard make on a dyno ?

 

[wogtaz ryder]

with a knobby its known to be considerably less

 

[sean01]

your hp figure can't be compared to anyone else, although i would of expected a little more..

going by the monitor screen you air fuel ratio is all over the place and still running lean most of the time..
13.5 on a cold night is asking for problems.
you want a steady 12.5 all the way thru..
even your low end mixture is up to sht..

it starts really lean the goes really rich then tries to stay nice and then leans off again..

bit sus on the rpm too, just doesnt seem right but things can sound different on video

yeah the guy did point out those issues with the mixture ratio, he suggested using a kehin carby would clear up those issues being a more tuneable than a oko, we noticed when we changed the pilot jet to a bigger size the throttle ran on when i backed off the throttle around the track.

also unsure of what you mean by your hp figure can't be compared to anyone else, well how do you know it should have a little more ?

oko uses exacly the same stuff as a keihin and iv never seen any of these leans issues on one of them..

lean pilot causes the engine to run on when backing off...
and it looks like you need a different needle or slide cut out..

what was the point of your dyno if you didnt get it tuned..
and as soon as i seen the ratio at 16 i would of shut it down..

are you still running that stupid boost bottle thing?

and also i havent really seen what jetting your running?

 

[teapot]

damn nice bike. sweet spec too !

yeah i am still runnin the boost bottle mate hahaha

40pilot 104main, mixture screw 1 and 1/4 turn out, needle is lowest clip position

what would you recommend as a carby setting ?

 

[sean01]

lol your way off.. which must be why i thought this engine would have more in it..

mainjet is way under sized, pilot seems about right but id be removing that stupid boost bottle crap..
its probly the culprit of the air/fuel ratio wondering all the time..

mainjet should be around 108-110.. i run a 104 in my 160

and you didnt say wat the purpose of the dyno run was.. tune? pr just a power run?

the dyno was to mainly see what HP it was putting out.
if i increase the main jet size to your recommendation would it increase the hp ?
in your opinion also what HP should my engine be putting out ?

 

[sean01]

hp readings changes from one dyno to the next so like i said earlier it cant be compared..

and besides its not hp that makes you fast (torque turns the tyre).. hp is a factor of torque so tune for torque and disregard the hp.

and i think you got a lot to learn about with dyno's.
dyno's are a tool but get used a lot in pissing contests.
there used for back to back runs for tuning and performance gains. you can only use 1 dyno while doing this..
even same dyno but different times of the day can give different readings unless the user corrects all this in the software.
which you should of seen him do prior to running a power run..

as for your other question regarding the main jet... you work it out its not rocket science..

yeah ok,
also in one of you last comments you said "your hp figure can't be compared to anyone else, although i would of expected a little more.." what was this little bit more figure you had in mind ?

also what are some of the hp/ torque figures that you have seen/done on these horizontal engines ?

 

[roost666]

A pro circut EDC chip will greatly improve throttle response, also helps getting that extra torque aswell, gotta get a mark II tho
