T5 main jet ?what size?

[johnk]

I am currently putting a new T5 barrel and piston in due to a previous seizure caused by the autolube failing, I am going to remove the autolube and their is currently a 112 main jet, Do I increase this to a 114 main jet as I will be pre-mixing?? and the exhaust is currently a simonini,any info would be greatly appreciated.

T5 standard main jet is 110 so the 112 should be ok with the Simmo. Just to be on the safe side you can try the 114 and do a plug chop. But it's always safer to run ever so slightly rich than to run weak!!!
