Headwork and 1270 kit

KAWITOM · 09-29-2008, 04:46 PM

I am trying to get some feedback on something I'm trying to figure out, I have A-1 model with a 1270. I've been running it for about four years with a dry shot, I'm thinking about getting headwork, cams and a valve job (should I go with bigger valves?). Any combinations that anybody has put together with HP and Torq that have worked out well would be greatly appreciated the bike went 8.83 with a 160 pound rider, that's not fast enough I want somemore and also does anybody know how much HP stock rods can handle before you have to start worrying, I've heard 300 HP is that true. later kawitom, trying to figure out my winter project,.

I dont know about valve size but i do know that a guy from sweden has a 1427 stroker that he has raced for several seasons on stock rods.
donty know how much power it makes but i have seen him go 5.5@135mph at the 1/8 on motor, regular hand clutch and 59.8 inches wheelbase

dont know how much power it has but it seems the stock rods can handle some power

Sal at Ace Performance has some seriously fast big bore ZX-12Rs coming outta there. Get in touch with him and see what he can do for you.

Sal sells track results, not dyno numbers. So if your looking for big hp/tq numbers, he's not your guy. If you're looking to mop the floor with the guys sporting big dyno numbers at the track, give him a call.

No bullshit, Sal builds the fastest 12's in the country and has proved it over and over at the track.
