Need some info

[blaster7]

Alright well hears what I need to know guys,I would like to know the compression ratio I'll be running? I'll tell you what I'm running vitos 240 with forged piston ported cylinder the exhaust is ported 2mm and a 3mm stroker crank,the reason I would like to know is because of fuel octane,so if anybody has any clue let me know guys.

 

[blaster7]

also how about octane boosters? I've used rocket fuel in my 250 race bike and it seemed to work great and that's what all the guys use when we ride,should it work for my blaster? or is there any other boosters that work good.

Head shaved?

Google how to calculate your compression ratio. It's a lot of math, lol. The lazy way is to go by your compression psi.... Generally Speaking anything above 150 needs some form of race gas...

Octane boosters scare the sh*t outta me..

 

[blaster7]

nope,no shaved head buddy.

 

[jlsparky7]

You should be fine on premium pump gas...

thanks buddy,your always hear to answer my questions thanks man,oh why I have you hear what should I get for a compression tester,I'm getting it from eBay is there a specific thread size or do the kits have the specific sizes in them that I need? again thanks for your help buddy.

I believe typical compression testers have the thread size you need. I bought the one from harbor freight and one of the adapters worked out perfectly. Heres the link
