ms4x4outlaws Posted November 23, 2009 Report Posted November 23, 2009 well I have heard about the mod and i have most all the other mods done to my bike. Im looking for a little more power and i was wanting to go to a 4mil but i think this will hold me over for a while. What kinda power do you think im going to get with this? I have t5s, fresh motor thats ported and tuned good, vforce 3 reeds, k&n pods. There is no boost bottle though i bet thats going to kill the big power Quote
locogato11283 Posted November 23, 2009 Report Posted November 23, 2009 just timing? you might notice a little, but its not gonna be a night and day difference. Quote
AKheathen Posted November 24, 2009 Report Posted November 24, 2009 bump your comperssion, too.......both those together will give you a little noticeable power. figure what fuel you are willing to run, and get a coolhead with the appropriate domes Quote

There is no boost bottle though i bet thats going to kill the big power i would go 4 mil for more power. boost bottle doesnt do anything u dont need it Quote
ms4x4outlaws Posted November 24, 2009 Author Report Posted November 24, 2009 (edited) i would go 4 mil for more power. boost bottle doesnt do anything u dont need it I WAS TRYING TO BE FUNNY ABOUT THE BOOST BOTTLE i know it doesnt do anything. so I just put the reeds in last week and i noticed a small diff, Is that the kinda diff i will notice wiith the timming? and run 100oct fuel 927cast oil Edited November 24, 2009 by ms4x4outlaws Quote
AKheathen Posted November 24, 2009 Report Posted November 24, 2009 you can probably go with 18cc domes and still have room to play with the timing for more than +4. it's best to talk to the guy who ported your cylinders as to what size domes, compression ratio, etc. your elevation will decide also. you will notice a stronger midrange and smoother power hit, but not nescicarily gain that much, even though it may feel like it Quote
ms4x4outlaws Posted November 24, 2009 Author Report Posted November 24, 2009 well thanks for the comments, I guess when this motor goes, ill be doing the stroker kit. Quote
ms4x4outlaws Posted November 26, 2009 Author Report Posted November 26, 2009 well i put the timming plate on and set it at +4....... well When i started it, it sounded like it was running on 1 cylinder and he a little less power. so i backed the timming down to like +2 1/2 and it felt alot better, took it for a test drive and it felt good. my question it y did it run bad with the +4??? i set the timming mark where the cases meet, Quote
No Limit Powersports Posted November 27, 2009 Report Posted November 27, 2009 probably didnt get the key back in the flywheel correctly and your timing was way off, then when you took it off to change it you got it back in correctly the 2nd time. Quote
volcrano Posted November 27, 2009 Report Posted November 27, 2009 probably didnt get the key back in the flywheel correctly and your timing was way off, then when you took it off to change it you got it back in correctly the 2nd time. if he even took the flywheel off as you dont have to to adjust timing if the plate is already on.did it run bad or just not he same?with ur setup,+4 will increase low end power slightly and increase throttle response,but u will lose top end pull doing this.set it up for ur riding.also,if ur gonna do a 4 mil,u unfortunately have to run a spacer plate now since its ported.call ur builder and see how much he cut-its possible it was a cleanup and he can adjust port timing to the crank stroke.if he can,u can ditch the problem making spacer plate idea and just run the 795 wisecos with cut domes to ur octane preferrence.even if he cant,u can still run ur setup with ur port and run the spacer plate,but it is known to be a spot of problems with compression/vaccum leaks because of the 2/4 gasket shitty setup.as for timing-u might wanna just leave it but i hear there is no difference until u hit 4 degrees or higher.plus with ur setup,u are wasting money with 100 octane.u dont need it for the compression u have-itll actually feel better with 87 with 6.5 to 1 compression.hope this helped.

I do alot of drag racing. the next thing im going to do is a head mod or an aftermarket head not sure? And thinking about carbs too. what do yall think? Im not going to do a 4mil intill this goes and im thinking that this set up is going to last me a while, I was going to get new jugs and and crank and 35mm carbs when this motor goes pop. Quote
GNR101 Posted November 27, 2009 Report Posted November 27, 2009 when i had mods like urs.. i stuck a cool head to boost the comp and then put some pwk33s lost some bottem but gave me alot more mid n top i liked the carb upgrade Quote

I just dont know if my crank is welded from the previous owner, I kinda think it is though because he had it totaly rebuilt right before i bought it, and i know for sure the crank was replaced. Quote
AKheathen Posted November 27, 2009 Report Posted November 27, 2009 are you sure you had the pickup gap set right when you had it at +4? it can change a bit every time you loosen the bolts. if you plan on doing a 4mill later, you will be money ahead to just buy an aftermarket head for the price you will have to pay to work yours twice....and you can just cange the domes out to suit your needs Quote
