Moderator Airhead Posted December 8, 2012 Author Moderator Share Posted December 8, 2012 Nice one Ken, dont bother about getting the red off, just sand down any rough spots and key the surface then simply spray it heat resist silver How much did it go for BTW? I sold mine many moons ago mate Link to comment Share on other sites More sharing options...
kenDAWG Posted December 8, 2012 Share Posted December 8, 2012 paid £20 posted for 3mb head - £70 posted for re-lined cylinder ill look into the paint! what sort of performance gain did you notice if any with the 3mb head? i cant get mine to go past 60mph i would be happy with 70mph so i could keep 60 constant without having to red line the bike i mean if the head does give it a little bit more snap off the mark ill go up a tooth on the front sprocket. im just worried if i go up a tooth ill kill the acceleration!! i like my little bike so i dont wanna ruin the ride cheers ken Link to comment Share on other sites More sharing options...
AndyDtr08 Posted December 8, 2012 Share Posted December 8, 2012 Sounds like you got a bargain there Ken. Nice one. I've also fitted a 3MB head but did ride this particular bike without it as it was a non runner when i bought it. Mine will get to 70 (on the clocks) and I've not yet taken it to redline. My acceleration is still very good. I believe im on standard sprockets but never actually checked tbh. Keep us posted! Link to comment Share on other sites More sharing options...
kenDAWG Posted December 8, 2012 Share Posted December 8, 2012 thats what i thought 70mph should be reachable in my opinion but ill not know what sprockets its running until i pull her to bits and check everything over!! i have a 17 tooth front sprocket and i think ill get a couple more have a play about with it see whats suitable to me cheers ken Link to comment Share on other sites More sharing options...
Moderator Airhead Posted December 8, 2012 Author Moderator Share Posted December 8, 2012 I had 80 downhill on a motorway, only once though I just wanted to see it off the clock :0 I'm far too sypathetic a rider normally and would be happy at 65 most of the time, after all those bikes have the frontage of a barn door!!!

kenDAWG Posted December 8, 2012 Share Posted December 8, 2012 thing is mine is on the red @ 60mph, if it could do 70mph i would be happy at 60mph all day - just feel as though im killing my baby lol Link to comment Share on other sites More sharing options...
Moderator Airhead Posted December 8, 2012 Author Moderator Share Posted December 8, 2012 well either you have 5 gears or someone downgeared the sprockets then! Link to comment Share on other sites More sharing options...

AndyDtr08 Posted December 9, 2012 Share Posted December 9, 2012 There are different clocks. Some have red line at 9.5krpm and some at 10.5krpm. Mine is 10.5kprm. My clocks are import clocks in kph. I've fitted a speedo converter on the back of the clocks so to get off the clocks i'll have to get to 140mph indicated. Do you reckon i should try !
