I have a warped carburettor body on my dellorto SI2424E . Im going to replace it. I'm also changing my exhaust to a SIP road 2.0.
I have read that you need to use at least a 118 min jet. However I'm wondering if I should also change up to a 26mm carb. The rationale being that the bigger carb will help keep the engine cooler with the new exhaust.
I would prefer to stay with the 24 mm carb, as the 26 m is much more cost . So my quesiton is this. Is the 24 mm carb with the 118 main jet going to be OK or is really worth going to the bigger size 26mm.
My main focus is making sure the negine is running cool as possible, im in Jakarta Indonesia, the temperature is never less then 29 degrees C, and the chances to open up the thorttle and go fast are very limited any way so speed performance is not a key issue.
Thoughts and comments appreciated.
