id try more around a 33mm but once again im gana ask are you sure its a vitos cause i coulda sworn that before you said that it was a ct and now its a vitos have you mesured the cylinder???


they have alot more done thien you do they can use a carb that big but alot of them are drag raccing the bigger the carb the less lowend but more topend lowend is what you want for mx

my motor is modded out but the stator is the only thing stock besides that it is modded out

first off that wasnt a ct that come on that quad i looked at the thread when you bought it i only saw 4 bolts on the intake also in that thread you said it had one bore left now its junk you change your story to much and trust me theres alot more to build on than your setup you still have porting witch a stroker crank without the port timing matched doesnt do much to beging with you still have way more room to go

 

[speedemon17]

i was told it was a ct but whatever and it must have been resleeved or something but i have ported the cylinder i watched how ken o conner ported his and i went out and did the same so it is ported

 

[York Racing]

Still.... The best carb for motocross would be your 30mm oko.

 

[speedemon17]

ok i will run the 35mm in the first heat and the 30mm in the secound to find out which is best

 

[hudack]

there is alot more to cleaing up the ports of the cylinder you get some power gains from it but not what you can when you send it out to ken,wilcard or flotek they dont just clean up the casting flaws and just cause u cut into it with a dremal dont mean the port timing was fixed from the stroker crank lets see some pictures of this porting you did while your at it take one of the triple exhuast ports and show us its a vitos to

 

[York Racing]

Ok. You have fun with that. With motocross you want to get acclimated to the setup that you have or you are going to make big mistakes.

 

[speedemon17]

my motor is all together but i can take a pic of it all together would you want me to do that

 

[York Racing]

Whatever you want to do. I'm just telling you that the 35 is going to make your wheeler boggy as hell on the track.

 

[speedemon17]

i dont think you can race competitively with a 240cc kit. you have to keep it stock bore and stroke so it doesnt exceed 200cc. if you just wanna go to the track and have fun thats good. but if your gonna race, you should trade that 240 kit for a ported stock cylinder and a stock head. you will make the same or more hp with a ported 200cc then a non ported 240cc.
