On a motor like the TS1 which is transfer time-area deficient, you sometimes have to increase the timing to get what you need.....again, pipe dependant. As long as you don't over extend the transfers and then have to chase the exhaust timing to get the correct blow down, which then can end up too peaky, you can do most of what you want with carb and pipe combos.Adam_Winstone wrote:... or too much transfer timing as standard
Yes.ridden not hidden wrote:Isn't it cheaper and easier to find a pipe that has the characteristics your looking for ( where you want the power and how you want it to rev and what port timings it is designed to work best within ) and then match the barrel to suit? that's what I did
Darrell has a plethora of Dyno results for various pipes on various kits, and can alter the tuned length of the TSR pipe to suit your port timings.thebassmasta wrote:darrell is modifing a tsr evo pipee for me, unfortunatley the barrell wasnt tuned by him so he requested the information
Yes they do, and places like Scooter centre publicise them on their site too. But 'standard' timings for any kit can alter from engine to engine with different cases, different crank strokes, rod length/packer/gasket combinations etc...mick1 wrote:Won't AF have the standard port timing info', might be worth a call/e-mail.
Looked on their site but it doesn't give that info'..........wouldn't it be nice if the kits were sold with the basic port timings/maps listed
