Right now, I'm debating if I want to abandon the 650SX build and go with an SJ. I could take my engine out, bolt on the pipe, drop it into the X2 and have a super nice X2. Take everything else, sell, and invest in an SJ. That's why I want to try the SJ and the X2. If I hate the X2, I'll keep the 650SX until I finish the SJ, if I love the X2, I'll get rid of the SX.
How much better would the high compression head be on my stock engine? It seems like it might be a lot of hassle and extra fuel costs for some extra power. Isn't that high compression head pretty rare? I heard it could pull up to $200.
I suppose I could just leave my SX as is, save the needed parts for the X2, build the SJ, then scrap the SX and build the X2. I REALLY like my stand up. It's a lot of work few people would bother with, but I was out in the surf yesterday and damn... it was just so much better than a sit down.
Edit: I'm just thinking why I would need an X2. I'm having a hard time thinking of a reason. I thought maybe the new girl would want to go out, but I bet 99 out of 100 girls I take out would rather ride my dads couch. I suppose it'd probably be a waste of my time. I think I'm just getting caught up in the "omg, I'm getting to build something" thing I normally do.
