i know alot of guy's on 900rr's ask this q. so i want to tell my experiance. i just rebuilt my 99 and she is sweet( look for pic's on stunt pic. soon.) i cut the erion header right after the 4 into 1 and cut the can down to like 8 in. and it all stay's under the bike (no more dump out the right side and the bike run's on the bar now :YEAH before it would shut off like 1 sec. after it got on the bar the only thing i can think of is there is more or less back pressure? i always here people talk about float level and jetting. but i noticed in some videos peoples exhaust having no can or disconnected . is this the reson why?

 

My 900rr stalls very quickly once on the bar too... ive been trying to find out why for a while to no avail. It doesnt bother me, as I yet havent installed a modified oil pickup and am worried about doing damage to the bottom end.

 

yea im not worried about draggin on the bar(i don't do many bar trick's anymore) but i was afraid of doing a spreader or x-over scrape and that biatch shutin off that could leave quite a mark if you no what i mean.

 

ive wanted to make custom carb boots out of old auto radiator hoses that allow the carbs to be angled forwards.
the boots would be longer so the low end would suuck
