Not saying they arent but if your engines are what you say they are and what ive seen from your vids then this little motor should move really well with some of your handy work.
I would be definitely willing to give the engine a shot...I have not modified one yet, so its hard to say what can be done till I actually measure up the engine....But I can make more power with pretty much any offroad engine i come across....Feel free to send it in and I can have a look at it...
