Carb mixture setting - s25mjohnson - 19-04-23
Wondering if anyone has a recommendation for a make of offset screwdriver to adjust mixture screw.
Also has anyone had experience of using a Gunson Colourtune kit to set the mixture correctly.
Finally, if I decide to have a go at servicing the carbs, any recommendations for refurbishment kits. Yambits sell a kit for £11 approx per carb but that doesn't include new jets etc. Had a quote of £350 ish to refurbish the whole carb set and told the parts are around £30 per carb. Thinking I should know how to do this myself (without buggering it up!)
Bike was off the road for two years and stuttered a bit before the revs got up. This cleared up somewhat after an hour or so on the road. Something sticking and now freeing up? 20 years old so probably worth a refurb by now. Oil, filters and plugs all new.
All advice welcome

Look at the Yamaha service manuals in the download section for the correct carb settings for your model.
Rebuilding the carbs isnt difficult - getting the foccers back in can be a bit tricky though.

Wouldn't hurt to put a whole bottle of this in a full tank and let it run its course.

You can put the whole bottle in, but make sure you have a full tank.
