So ive already opened the exhaust valve gap up a few months ago.
And it not starting again and put me hand over the exhaust and i can feel a reverse pulse while cranking
So is it the valve getting longer or are the valve seats getting hammered into the ali head
maybe I need a rev counter like a row of LEDs
how many time can you stretch valves or whatever theories you may have ;D

I do not know if you have stretched the valve, it is possible I guess. I do know that the valve adjustment seems to need to be checked frequently.

well it cost $13 for valves or $40 for a new head But I guess it will go if i reset the ex valve Attachments:

Parts are cheap but if an adjustment is all it needs I would do that first.

yeah yeah I agree
Its raining and I am waiting on a new CDI to come in the mail
I was hoping that somebody would know the exact reason that the gap closes
I have a few mini chopper type motors that I have ridden to destruction the heads are different but I was wondering if the valves inter-change
Also I want to find a spring damper that is a spring wound out of flat steel and fits inside the outer valve spring and lessens the likely hood of valve float

Also EGR style heads would have hardened valve seats which could put a stop to valve seat recession

An exact reason, I don't know. I do know that. Valve lash adjustment seems to be frequently needed on these. One of the founding members here was a genius with these and he would modify the springs to cope with valve floar. I think there are some you can order out there too. Check out the thread "Jewels from Kliff" in the 125cc and up area. There is a valve springs thread he did there. link to the valve spring thread; scooterrebels.proboards.com/index.cgi?board=125plus&action=display&thread=436 |
