After a bit of delay waiting for parts I finally have my '05 T100 cleaned, polished, reassembled and on the road. Here is my current configuration:

TORS
AI removed
Snorkle removed
Uni filter
Restrictor removed
128 mains
42 pilots (2 turns out)
Slides drilled
No shims

Not having ever ridden this bike before, or any other new Bonneville, I don't know what to expect for performance. I have been doing a series of roll-ons in 3rd and 4th gear starting at just under 3000 rpm. Power starts to really comes on strong from about 3800 rpm on and I have yet to get past 5500 rpm as I am going too fast by then.

I think maybe something is not quite right below 4000, perhaps too rich, although the plugs don't indicate it. No spitting or popping on decel. My next step is to try the 125s and test again.

So is the power curve normally pretty flat? Am I looking for something that just is not there? Above 4000 this thing is white-knuckle fast. For perspective my other rides are a '97 FLHR/I (big twin fuel injected Harley) and an '88 R100RT (1 liter boxer twin air head BMW).

they dont start to get fast till 5000 let her go 7500 wont hurt it at all.

Ditto mikeinva. These engines love to rev - definitely no HD.

Got any pics?

coming on at about 2,500 and be pulling hard at 3500 and hit the freight train feel by 4000 and it should keep building totally linear to the rev limiter. Depending on your pipes I would guess your mains are a little small, the 40 pilots are probably fine as long as you have an airbox at all. if yours has an 18 tooth sprocket it will delay the feel and a full roll on in fourth will not feel strong till about 3800 -4200. if you get a burst at wot fron 2500 and then a little slack till it catches up you need a shim, or to raise the float level just a little.

sorry I missed the tors the mains should be fine, add a shim .5mm, the 40 pilots should be fine.

Sounds like it is behaving as it should. 18 tooth sprocket. I checked the plugs after the series of roll-ons and they look a little bit lean. The tan has gone to gray and the base soot is about gone. I think I will ride it awhile normally, i.e. like the old man I am, and check again. If the base soot has not returned I will go to the 130s and see how they do.

A little futzing around with the pilots seemed to make no difference at idle so I need to investigate that also. I have read several times here of others having the same symptom. I will also connect my handy homemade ATF carb balancer.

Just out of paranoia I checked the wheel alignment and sure enough, it was out by nearly an inch!

I might have noticed eventually, if I looked and saw two wheel tracks behind me.

Oops, time to change my sig.

If you get the plugs to look like you think they are right like the old days then take it and dyno it with a exhaust check you will be way rich.This is not the same gas we use to run most of it is part alcohol it dont color plugs the same.If you ran stright alcohol all you would see on the plug when mixture was right is a very light grey that you really have to look for.You dont need great big mains with your set up if i was to guess i would say 115 to 120.at the low rpm your testing at with the cv carbs you might not opening the main 100% anyway take it out in high gear run it wide open for 3 or 4 sec let off just a hair maybe 7/8 if it picks up its lean if it dose not put a smaller jet in it till you find a size that makes it pick up when you let off then go back up one size and you will be close.after you have the main right add a shim see if it takes off better from 1/4 throttle to 1/2 if it dose try 2 shims if 2 dont help leave just 1 in it.but if you want it right put it on a dyno.
