Dt1 Carb Spacer
« on: June 11, 2014, 09:32:05 AM »
Just wondering ... whyt is the huge spacer between carb and cylinder on the dt-1 for? is it really necessary? what effect would it have to remove it apart from having to find some new connection to the airfilter?
There´s no specific reason, just everytime when i work on my bike i´m asking me this question..
any idea?

Are you referring to the insulator spacer? Heat mainly.

 I would suspect that appart from heat transfer, shortening the inlet port by removing the spacer would weeken bottom end torque,  and also interfere with jet settings,
dont follow me i'm probably off line!

There were 2 types the Enduro as standard and a thinner one that was used with the GYT parts , With jetting changes it helped the motor rev but at a loss of bottom end . Iain

Thanks. That was my guess, too.
