Where to purchase bigger jets for my '78?

[Diskman01]

How do I go about buying larger jets for my '78 XS11? Can I just hop on ebay and search for Mikuni jets? Im looking at 145 mains and 45 pilots. (4 into 1 exhaust and its waay too lean).

Any advice?

Thanks!

MIKE'S XS has those jets at $6.50 a pair.

MOTORCYCLECARBS.COM has what you need for sure.

That will get you started.

Hmm.. MIKESXS only has XS650 80-84 jets? DO you know if they will work in my '78 1100?

Never mind.. Seaching worked! I guess the 145s will fit.

Thanks for the info on the sites. Whipping out the old VISA ASAP.

80-84 XS650's have BS34 carburetors like the XS1100. Earlier XS650's have BS38 carburetors, unlike the XS11.

I gave you the second link because there shouldn't be any guessing there.

As well as Marty's sources, there is aguy on ebay sells under "Georgefix". If you contact him, he will sell you whatever jets you need.

You can also just go down to your local motorcycle shop. I found my jets at a suzuki shop. They were cheaper then online when you add S & H. Just take in the old ones to match up.

The only local motorcycle shop here is a mega Honda, Suzuki, Yamaha, etc. dealer who offered to sell me jets for my '80 CB650 for $55 each (x4).

I ordered the following from mikesxs based on further info I have read on here somewhere..

#145 Main Jet - Large Round Type - N100/604 Mikuni type - Fits:1980-84 Stock
XS650 Mikuni 34mm. CV carbs and aftermarket Mikuni TM 36-68 Flatslide carbs.
Sold in 2's.

Not sure if I should have sprung for a set of 147.5s too or maybe 150s as ethanol gas is rampant in my area. (Engine needs more fuel with ethanol to prevent a too lean condition).

Kinda shocked that Mikes didn't offer priority US mail shipping. $10 UPS. Mail would have been about 2 bux for 4 small jets.

Oh well, beats the local dealer by a long shot! Hopefully when my replacement air-box intake boots arrive I can ditch these pods that the PO installed. I have them currently taped up with about .5 inch left at the top and it's still lean on the top with the 4 to 1 exhaust.

It's a project. At least it's been cheaper to work on than my Honda. lol The Hondas been assigned living-room duties anyway. Makes a nice centerpiece.

Alrighty. Called the local Mega powersports place today and asked for a set of large-round 147.5 jets. They can order them for $19.95 each.. BUT, the guy gave me another number of a local racing shop in town. They had my 147.5s in stock for a whopping 3.95 each.

Installed em, bench synced my carbs and installed some pod-lengtheners to keep the pods from blocking off the air jets as they were doing.

Top end is AWESOME. Bonus: the bike actually idles now. Still has a severe miss at idle (#3) is popping and spitting. Need to adjust a bit more.

Engine is cooling down with the 'ol box fan in the garage. Will pull the plugs and confirm enough gas is getting burned. At least I hope they are not still metal looking like before. gah.
