Firstly its a LML 2t 150 2010 reed valve model.
Originaly a 125, then changed to a 150 with all emissions systems left on and standard restrictive exhaust, airfilter and jetted to USA spec as per manual.
Upped the main jett by 2% as running pre mix
Then with the addition of sidecar I removed the whole restrictive system put a Sito + exhaust on and rejetted to pilot 55/160 main stack 160, BE3, 105.
All ran good only changed as exhaust rotted.
( still on pre mix )
About a month back fitted a Sip2 and 108 main as advised. Today was the first day I have had free to road test it. Started fine ran fine first mile then noticed revs taking a second or two to drop.
Then a mile latter stopped for coffee turned off ignition and still revved fairly high for a while.
Possibly not turning off due to duff switch as has happened on very odd occassions before but never the high revs.
Work so far
Checked both choke and throttle cable, both opening and closing as should.
Air filtration/Carb set up
Air filter is the early less restrictive one for without the extra layer of material in it.
The heart has not been drilled out
The underseat filter has been removed.
Carb 20/20 pre mix version
Reed Vaves still in place
Mixture screw one and half turns out.
pilot jet 55-160
Main stack 160, BE3, 108
Exhaust SIP 2
( still on pre mix )
I could not check plug as no plug spanner available.
Any help much appreciated
Many thanks
Graham
