Has any one ever herd of running 2 stroke carbs on a 4 stroke bike is there any way to set them up will it work. I need to put bigger carbs on my raptor and i have a set of old banshee carbs 35mm sittin in the shop and i was wondering if there is any way to set them up where it will work? thanks for any help

 

It could be setup to work but, it may not be worth the trouble/problems:


1) Lack of a accelerator pump alone could make it bog worse than your stock carb(s).

2) You will need to tune the carb from the ground up, pilot, slide, needle, main.

3) Because 2 strokes have a lower air velocity for their size, A lot of 2 stroke carbs will have a small sloted cylinder on the top of the needle jet. I'm not sure how big if a problem this would be..

For something like a raptor 660, I don't think it would be worth messing around with... unless you can get your hands on some baseline settings. Are you sure you need a bigger set carbs?

 

Thanks and yeah i'm pretty sure i will havent got bike completely back together yet but I have a 720 kit and boondockers 20 shot what do you think i should run carb wise?

 

Either get the stockers bored and increase the flow ability or step up to a set of dual FCR's.

 

does any one know if i Can i get 2 stock carbs from a yfz 450 and run them, wil ti work with the hot start cableand the TPS wiring harness?do they need to be taken off or what?

 

You're in for a lot of headaches! If I were you I would either check ebay or save up some money and do it right!

 

y would it be a headache? what is the diffrence in the dual 39 fcr kit that is sold for a raptor, and the stock carbs off of the 450

 

A few hundred dollars in parts to make them work together and a lot of down time.
