I typed that wrong....
It should read They will sit 1mm down from deck if you use 1127 rods on 1052 crank
1052 & 1127 Rods are the same ..Crank stroke is different ..
1052 rods are 0.5mm longer

Not personally mate im affraid

Do you think a 245 degrees and 9.27 in, 9.27 ex would make Much of a power increase?
them specs sound like Kent suz7 street cams? Had a set of them in my old mans old motor i built, picked it up a little mainly noticable in the midrange untill i tweaked the cam timing a bit
-
It should give it a bit more power in the top end and midrange depending on how u time them in
-
Duration is around 235 degrees and i think the lift is about 9mm on inlet and 8.7mm on exhaust iirc.

Defo. APE studs and torque it down to 42ft/lb. Then enjoy some trouble free riding
Never had a MLS gasket let go even with high comp and 100+hp nitrous
-
MLS shouldnt have let go at that, what was the head torqued down to?

That'll be why 90% of the record holding bikes use the NX solinoids then?

Nice. Oil cooled engine?
How quick?

MPM semi 10w40 or 5w50 synthetic if racing

Correct Clive. New gears from Suzuki are undercut from the factory

Very tidy bike dude

That doesn't make any sense - firstly GSXR cranks don't need welding - that is unless you are doing the journals to regrind and stroke them. Secondly I know of plenty GSXR cranks that run 180+hp NA that have 100+hp of gas throw in for good measure.......'they' don't break that easily - the other bits do!
You couldn't press together a plain bearing crank - you'd never achieve acceptable journal parallism without regrinding, GSX's have rather 'sloppy' main roller bearings that accept that tolerance of build.
what i meant was. I know of people who have stroked gsxr cranks by moving the journals and welding them up and they havent been as stong as the stock crank. Hence why i said it would only be worth doing on a press together crank like a gsx. But as you said. Even then it may not work for the effort involved.
The stock cranks can take alot of power. Ive put approx 300hp on mine no probs and i plan to go more. There was someone in the US who made just over 500hp on a stock crank.
Is reworking the crank worth the effort? Id personally say it isnt
-
Dont realy need em. I got logging to prove it
-
Its known that the weld up gsxr cranks dont like going much past 180hp. U could build a plain bearing crank up similar to how the gsx cranks are made. Would be a better solution in my eyes

Ran buttons in mine for years with no real issues.

150-155 usually more than sufficient

NIce bikes! Quick question though (and I know naff all about drag racig!) how come you only run a single disc up front? Would have thought you'd need all the stopping power you could at the end f the 1/4
because the run off is a half mile long so u dont realy need that much brake to slow down. I only start braking half way down lol

Dont realy know at the minute. Theres 2 factors, the major one is money, the second is time. I dont have the funds to race now the missus is on maternity leave, so it could be 2017 before i race a full season again. Baring this in mind, im not too worried about sorting the bike just yet so concentrating all my efforts into the new Outlaw build which is taking up alot of my time.
As long as we have at least 1 bike out on track to represent the team then thats all we are worried about. Ady's doing a great job in 9.50 bike and is sitting 3rd in the championship with 2 rounds to go so with a big team effort, we mite even sneak a big trophy at the end of the year
-
im sure many have seen the bikes before but heres a few of our current race bikes. The slabby has been sold now tho and im not allowed to mention the other but here we go
GSXR 1100M Nitrous, GSXR1100G Nitrous, GS1100R

Enough to easily run 8.9s motor only and 8.3s probably 210-220bhp. Should have close to 300hp this year
