Can an xl250s run a 36mm TM Mikuni?

[Russ447]

I am building a tuned xl250s - lightened ignition, bottom end, Joy cam. I was going to try a 43mm Mikuni, but I already have a 36mm TM flatslide (without accelerator pump). It will be a race bike so I don't have to worry about how it runs around town.

Does any one have any experience of running this type of carb or something similar on an xl250? If you do I would be interested to hear how you got on - before I buy a suitable inlet manifold and lose several days playing with jets.

Thanks,

Russ

I'd have thought you'd be able to get it to run OK.


If its a bit big - low down may suffer a bit (less torque), but it may well gain higher revs?

Suck & see - part of the fun

Thanks - I think I will give it a go. If anyone has any ideas for a base line set up - needle/jets I would be interested to hear.

US racers seem to think a 36mm will be ok, some even run 38s on super tuned stuff.

Will let you know how I get on.
