glowing clutch

[robin]

i just finished my bike then i take it for a long ryde i then i came to this huge hill
i culdent get a run on it tho so i was had the throttle on full and i weas doing like 20mph then i heard a pop looked at the clutch it was starting to glo red then my chain came off now when i start the bike it trys to move without eny revs i think ive cooked the spring is ther any was to fix it ?

[robertdjung]

yeah sounds like you screwed the clutch. when the engine is off -- is the clutch engaged?

[robin]

tor when its running it just engages at a lower rpm and i find if i just give it full throttle it dont fully lock up till about 30mph but if i get to about 20 then let of the throttle then llet it back on it acelerrate faster

[robin]

erm the clutch totaly went it the brushing has melted and i cantand some of its disapeard i think

[athif]

ooo, yhea u definetly screwed the clutch, dont bother trying to fix it cause once u open it up u need a machine to put in the new high resistant springs which would cost u even more money, just buy a new one, its alot better.

And change gearing.

i did fix the clutch i replaced the bering what was left with it with steel tube it worked perfect till the clutch came lose and flew apart ime thinking of gering up the motor so that it spins the clutch way faster

[kibble]

That might just burn up the clutch faster as the clutch still has to face the resistance of turning the wheels on the other end. Or it might try to engage at rpm's that are way too low for the engine. At least that's what I think, I could be wrong.

[robin]

yeh it tries to engage at lower rpm

[2or3wheels]

How many teeth do your sprokets have and size of the wheel?

[robin]

erm i had a 10 toth sprocket with a 53 on the wheel and the wheel is 22inch

i switced to a 40t on the rear and and my frend got 70down a hill i dident have the balls to do it tho ina real bike but not that tho it did about the same up hills with the 35tooth setup apart from real long hills my engin tops out at about 4700rpm ime going to tak the engine out do more porting and polishing make new manafolds bigger and a better exhaust and clean the frame

[robin]

i tok of what wasalreay on the clock and so far ive done about 250miles thats in the week i was driving it befor it broke

[2or3wheels]

That gearing is why your clutches are glowing.

[robin]

yeh thats why ime am gering it to engage at lower rpm and its a 8hp and thats wht the cluthes are rated for

[2or3wheels]

but if it engages earlier and still has same gearing wont it burn even longer?
