I used one of these as a needle shim. It ran about the same. We'll see how it affects my mileage. Now on to my point... When I put things back together I forgot to tighten the boots between the airbox and engine. It ran fine at low speeds. I got on the freeway and it must have been sucking air around the boots. I could barely hit 60mph. I tried your choke trick and it sped up to 65-68ish. I guess with the boots tight my bike was already running rich enuff that the choke made no difference.

just thought i would share this as i found it after a good bit of searching.

My European model has a +ve crank case ventilator fitted as standard. It's connected by a tube & tee piece to the petcock vacuum line.[attachment=3:3vfxfwbp]b19.JPG[/attachment:3vfxfwbp][attachment=2:3vfxfwbp]b22.JPG[/attachment:3vfxfwbp][attachment=1:3vfxfwbp]b24.JPG[/attachment:3vfxfwbp][attachment=0:3vfxfwbp]b17.JPG[/attachment:3vfxfwbp]

I dont believe that can be done to the american model I dont remember seeing that area to add that feature i could be wrong, i wil check that out when i get home but I am almost positive that the way I am thinking about doing it is alot cheaper

ok new problems that I have come up with.

I have added 2 nylon #4 washers to the needle jet and put the original washer back on top of the eclip. and this morning i rode to work with some finagling and my result is that I can ride the bike and get here normally until it reaches top of the throttle around 3/4 then it starts struggling. I turned the mix out and it seems to be better but i am wondering if i pull one of those nylon washers back off and turn it a pit richer if that would cover for the lower needle jet and make the richness enough for the top end. I found that when at top of the throttle in 5th gear i could pull the enricher all the way back and increase speed by 15mph and almost level the fuel out. maybe that is enough for some input but maybe not i am just trying to use all the brain power that there is to resource this thing.

Sounds to me like you're just using a main jet that is a tad too small.
Go up one size, make no other changes, and report back.

Only test one thing at a time, to eliminate variables.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Just for some companion reading, I've got a recent story similar to yours.
I put a CN250 custom exhaust on the Qlink and had great low end and mid-range power. The top was a little weak, but passable... I thought. After a test run, I stopped at the light in front of my house and started smelling smoke. Thinking it was the new muffler just breaking in, which is not at all uncommon, I kept on going. Got to the house, and noticed that my shiny new muffler straps had melted. UH OH! Someone is too lean in the top end



I then rejetted, (very rich, just because it's a cheap bike and I prefer to run rich and cool than lean and hot) and started getting fuel delivery problems in the top end. It was actually working too good and using all the fuel in the float bowl if I tried to maintain 65mph for more than a minute or two. I had to open the intake even further, to create a stronger vacuum and gas flow, and then had to increase the mid range even more in order to keep the bike from dying out at speed. It took two disassemble sessions of the carb before I finally got it dialed in.

The bike now cranks and stars easier and faster than it ever did before, runs cooler and feels more stable through all speed ranges. I've actually lost some top speed, but I don't care. Rejetting and changing the flow characteristics of bikes, especially when you do it on your own, doesn't necessarily make the bike faster. It just makes the bike run better for your current intake/exhaust settings and leaves you with a bike that run better... not necessarily faster.

I have some spares. Have you already ordered them?

nope I haven't I really hate the bike parts store here it is like they have their heads up their butts 24/7/365 and cant get the part that i order... I can give them the part number and they will still mess it up.

I'll see what I have in the drawer when I get home this evening.
What size do you have in the bike now?
