Dave, I can simply machine the domes that were on that engine to work with pumpgas if thats what you want, its really not too hard. Then you dont need to find any
I will have you do that this spring. I found these mega2 inserts that I had. They are 780's. I just forgot what cc's they are. They are spare set I had for my Big Bore SRX. I am sure they are the race inserts. Since I have the trail inserts in now.. Thanks
