Hi All,
I've been playing around with my newly built GT186 motor which is going well apart from hitting a ceiling when it gets to 6500rpm (carb jetted as recommended, timing set to 21 btdc, TSR Evo pipe...)
It's certainly got some poke about it but I have built it using the existing Harry Barlow built crank which has a 116mm Conrod and an Li taper.... and I am running a Varitronic ignition. I'm considering changing the crank to something more robust whilst the going is good to a GP tapered crank and also then changing the ignition system to suit. I could just change the flywheel I guess but If I'm doing this I like the idea of having a full DC system and was wondering what recommendations would be on -
Crank - 58 or 60mm, does the extra stroke make much difference, and
Ignition/flywheel etc - what system would work best? Obviously the Varitronic is a complete package but if I am to move away from that, what would be a good choice of components?
Richard Taylor doesn't speak highly of systems like the Varitronic but I am assuming it is good to have advance/retard to some degree?
I'd be grateful for any opinions, preferably ones the won't break the bank! The GT cranks look great but they're not cheap, hoping to keep a bit of a lid on it..
Thanks!
