Topic: CB400F larger main jet sources (uk)

[kajtek]

after realising that my bike doesnt get as hot and runs better with the choke half on.. i need to re jet (stock intake, marving race exhaust with the baffle in).

not having much luck finding a uk source for larger jets (80, 85), any suggestions?

thanks

I'm looking for the same but I'm in the US. Of course I'll order from anywhere to get these. I was thinking I'd have to drill out when my engine is finished but would rather not. Anyone know if main jets from other models work on the 400f carbs?

You can get a tuning set from Sirius con Inc.  It includes five different sizes and costs about $40.

Great it's in stock again, I remember looking awhile ago and this kit has been out of stock for some time.

You used to be able to get them from Honda- worth trying Dave Silvers. If not I'd go to a model shop and get some drills- an 85 is .85mm diameter, and do them by hand, starting with an .80. Be careful and take your time.

That Sirius kit is $44, plus $20 shipping, plus by my recent experience with UPS there will be about 10% duty and 20% vat on that total $64, plus a further £12 collection fee minimum (and another £15 if you can't get to the depot in the week). So some caution is needed before buying from the US. Try a web search to see if you can get them from Japan too.

Sorry, no link. Might try searching on eBay. I've seen a few kits advertised on there in the past.
