P5xlt or 21-4
Hi
First of all sorry for my poor english.
I need a new engine for my truggy.
I am considering 21-4 or P5XLT, but I can not really find out what would be the best. I prefer stable idle, good run times and reliability. Last season I ran with Sirio CL7B it lives up to the first two things but not the last.
I hope you can help me.
