crack pipes?

i would go with keihin 33mm pwk. that way youre not too big but in case you decide to build a 4mm one of these days youll already have a carb that can handle them..

If FAST built the motor chances are you have a slipping clutch. a slipping clutch wont transfer power making it feel like youre not going anywhere. you need to check your clutch parts to see if they are worn..

what are your other mods??

just looking at how you have the tape held there it appears to be about a 1.75 inc opening.. thats a 44mm carb.. i hope you have a huuuuuge ass motor to run them on!

i would run at least 35mm pwk if not 39mm pwk. if its a drag bike you need to get some cpi or shearer to really mkae the top end shine. also, 210 is killing your top end. you need to get it back down to 175 or so. it will rev a hell of a lot easier..

so what are you trying to do exactly??

ok, so if the 10mm isnt worth it with the RZ jugs because the port timing wont work like you need it to, then why run these jugs at all? wouldnt it be smarter to just run stock banshee cylinders and do the 10mm as opposed to running rz jugs and doing the 7mm?? are the rz jugs supposed to make a lot more power or what? i understand you have the PV's for the extra bottom end but i guess i cant just see the point of swapping to the rz cylinders unless youre gonna make a lot more power with the 7mm rz as opposed to a 10mm stock.. i personally wouldnt go any bigger than 4mm on stock cylinders as my last 2 motors have been a 4mm and 10mm cub.. ok so you got me on the port timings.. i dont know much about that. i would just think there would be a crank/rod/piston/spacer combo that would accomodate doing the 10mm.. just trying to offer some ideas here. carry on! :beer:

good luck bro. hope you make it out alright and your house is still standing when its over..

measure the intake side and see what size they are... they look like they came from a streetbike or snowmobile.

ok well now youre not making any sense. if you have to run a 1mm spacer plate anyway then why not run a thicker one to accommodate the 10mm crank? thats just stupid not to. crank prices are the same as well as trenching. with either motor you really need to be running at least 39mm carbs, straight cut gears, lockup, big air filters and a good solid clutch. it doesnt make any sense to build a 7mm at this point. there have been many guys that built 10mm out of stock cylinders than ran very well.. honestly, i dont think you have any clue as to what youre doing is you think you cant build a 10mm. the spacer plate will raise the cylinders back up to get your port timing back to where you need it.

i have 13,000 posts.. geez i am a post whore.. :biggrin:

well you were running 17cc domes with your old setup. of course your compression was higher. if youre running 20s now drop to 19 or 18 and watch your compression go up.. i run my 10mm cub on about 170 pounds. that way its got decent bottom end and doesnt sacrifice revving on top because the compression is so high. i wouldnt get over 175.

if youre gonna go 7, you might as well go 10mm. it will be almost identical costs..

sounds awesome man. th cubs are great cylinders.. just wait until you want more power! haha.

not real sure on the times because the standard is really 300 feet, but sounds like it could be a good time. so from start to finish was grass? i bet as the day went on it turned to more dirt huh? how did your bike come out of the hole?

have you checked ball joints and tire pressure lately? lug nuts all tight?

dude, dont do it... get a 2nd job, sell your own ass, do something!! you gotta keep this nice ass bike..

id leave it at +4.. i run +7 but thats on a 10mm cub motor. i think youll be fine with the +4 but you could try the +7 to see how it reacts..

yo man whats up? welcome to HQ.. might try searching to find some of the things youre looking for. if you cant find what youre looking for then post up something.. but the htings youre asking are pretty simple and there are quite a few threads around about them.. :thumbsup:

have fun man. wish i was going..

no idea about the preserving.. but son of a bitch... does you banshee have motherfucking craptor plastic on it????!!!!! ::

by a guy?? ahahahaha im funnnnyyyyyy :yelrotflmao: :ermm:

there is no way!! razr 2 are more expensive and they are heavier. and ill guarantee they dont wear as good as knarlys do. the best 2 dirt tires out there when it comes to price, durability and traction ar the kenda knarly and the stock rear yfz450 tires..
