I Need Some Help Guys

[2001Shee]

Hey guys I bought a set of 28mm mikuni flat slides instead of getting the tors eliminator kit. Got them on the bike and seems to have a bunch more power but something weird is happening and I am about to pull my hair out.

It seems to be running great through the first couple of gears, able to hit powerband and everything but can't quite go full out. Once I try to hit 4th, I try to give it enough juice to hit powerband and it can't get there. The bog at WOT seems to get worse as the speed increases. Sitting in the shop I can take it from idle to WOT and sometimes it seems fine sometimes it starts wanting to bog. It just seems like the bog keeps getting closer to closed throttle as I pick up speed. Don't even think about 5th or 6th.

I have been tearing apart this site and search engines trying to find someone with a similar problem but can't seem to. From my reading I thought it was too rich on the mains. My 28mm shipped with 280s installed so I went to 260s, plugs looked the same from what I could tell so I used a set of 210s I had, same problem. I took the 200s out of my stock carbs and put them in and it seems to be running the best but still wants to bog on me full throttle, still not even thinking about 4-6th gears.

Its around 30 degrees here, 500 ft above sea level, parts are in my sig. I took the FMF reeds out thinking they could be doing it but no such luck.

I am stuck guys I have tried everything I can find. If anyone has any ideas I would really appreciate it. Thanks, Chris

You should be running a mainjet in the range of 350-390 with those carbs. I have all the specs for it in my notebook, but your way off on mainjet size. Its bogging because its lean.
