Engine kits??

[quad_freak14]

I was wondering if my moto engine will be competetive in about 2 years? Like 4-stroke B nationals and higher class local races? By this time i will have a race ready yfz(hopefully) and still have my Cannondale...this way i will have a race bike and a play bike, but I could always have one for backup.

I would like to keep engine work around $1,000? Im not the smartest with cannondale engines....but im still learning alot.
Also, how hard is it to get a cannodale engine out? Im sure it is alot harder than other quads i have done..?

btw..My engine has Nac's mapping and an HMF, otherwise stock.

thanks alot
