Big red big bore

[8586bigred]

I am looking into doing an engine build this winter. I have a nice running big red and I was looking at the 315 cc kit with the sleeve and piston from powroll or four stroke tech. Has anyone ran this? Or what about any big bore kits for a big red? I am curious about any kits y'all have had experience with. Thanks

Not too many build these up so I don't think you will get too many reply's. I have sent a few of my 315's or 317's to members on here but I didn't get any feed back from them either. Most of the time that's good news for us engine builders, no news is good news to us, it means they are happy and out having fun.:)

Do you sell these kits? I agree with you no news is good news. I would like to see what you have to offer. Do you have a website maybe?

I am Four Stroke Tech, plus I raced/worked for Powroll when I raced for American Honda.

Well that shows how much I know about the arsenal of friends on here. The 315 kit for a 250sx comes with sleeve, piston rings, piston, pin and clips right? What kind of increase do you think I should see with jetting and all of course.

I may be interested in a kit as well. Let me know what I need to do and how much. Thanks.
