Hey now!!
I just got to ride my fifty with the bbr 822cc kit installed . seems to have alot of top end. i have put a filter on it not kn but similar and a d@d exhaust i think thats what it is. any way its alittle boggy. Do i need to jet it. Im running the carb stock. And also im thinking i should run a bbr filter or something else. the filter is one from ebay looks like a replica of k @ n but i think its smaller.
should i drop a tooth in the front sprocket? too
thanks
andy

 

i would drop 1 tooth in the front and try putting your stock air box back on i think the bike runs better with it atleast mine does

 

is there a 82cc big bore on the market that runs well on the stock carb?

 

dont drop a tooth, add a tooth in the front. stock airbox, stock carb with a 62 main jet. done

 

FAB "you the **** Bro"
thanks

 

Yea My Bad Add A Tooth

 

If i were you i would just put a bigger main jet on it. What size are you running on it right now? Tell me what you have and i'll try to give you a good size to put on for a 80cc. Close enough to a 82cc bored out kit.

 

dig around on ebay and find you a xr70 carb
and intake
i run the d&d with this set up and a 15 tooth countershaft sproket
and a k&n on my stocker and it ripps
with an 82 itll ripp even nicer
if you can find a 70 head or a trx 90 head even better
stock stuff set up like fab works too just a little extra info for ya
blubbering off the bottom is because its lean and on a stock carb you cant change the pilot jet, you can on the 70 carb
