I have still yet to break in my 2105 as I have been busy with a couple other platforms . It’s sad OS released a V2 version like 2 months after the first one to try and rectify the issue some are having with the piston . Since I have the first version do you think I can take a rubber wheel and carefully polish the upper edges of the exhaust ports in an attempt to keep the piston burn mark free ?? To really add salt to the wound I preordered the Ielasi Gp23r then next thing you know there is a V2 but before that happened I ordered a Part set from ASM , needles to say I wish I waited some as I fear I will mark up each piston in time .
Thank you for the intel on the R2105 case capacity vs previous models , do you think using the r2105 case for the GT2 sleeve will be beneficial for a Gt engine ? With less capacity it may/ should increase response and torque.
