[xlr8_07]

hey guys,

re doing the loom and a few things on my race bike to get ready for the winter series, and i came across this thing, it appers to be an optical switch ? i havnt yet cut this current loom open but if no one knows then i will do so.

Wasn't it any any kind of casing?

[lewisdale]

how many wires are coming off it mate?

[xlr8_07]

it was cased in insulation tape hahaha, the guy before me that made the loom i guess? may have taken it out of the box?

it was 3, labled ; ign, out, gnd

[xlr8_07]

little more info, ign is hooked into power supply to cdi, ( red in four pin plug ) gnd is conected to a ground wire, out is hooked to the pink wire in the 6 pin plug on cdi, was hooked up with nothing obstructing the switch if that makes sense ( nothing in the line of the IR beam)

when me n redex rob deristricted my h2, we done it by using the internals of a speedo, and that looks very familiar!!!!!!!!!!!!!!!!!

this little blighter??

thats it

[WelshD1K]

its the 180kmph restrictor thingy but its out of ur clocks so should be ok

[RedexRobB]

yeah thats restrictor unit from restricted clocks. That big black bit would normally have a tag that passes through it when the clocks reach 180km. Without that tag it is effectively a derestrictor because the tag isnt present. So your CDI will never be told that its reached 180km and allow you to rev through to your hearts content

[xlr8_07]

oh kool, cheers guys A+ now next question, can i scrap the lil F*cker?

[lewisdale]

if you do youre revs will be limited to about 10,000 rpm

[WelshD1K]

no you cant m8t. the bike will rev clean to 10k then and splutter( i disconected mien earlier by mistake when cleanign it and then couldnt work otu why it was spluttering @10k)

[xlr8_07]

hmmmm that wont be handy considering iv got now power until 8500 at the moment haha , i will get onto invstigating what sort of a signal it is sending the cdi to work out how to by pass or trick the cdi, will let you guys know how i get on

[RedexRobB]

its as simple as a 100 ohm resistor between the brown and pink iirc
