The bike is an NSR 250 SP-(1992)
It is an ex race/track bike recently imported.
When starting from cold in the morning the is a large pool of petrol/oil mix under the bike.(oil pump has been removed).This is even though petrol tap is off.The left hand pipe throws out a lot of crud on starting....this seems to be unburnt petrol/mix.
Why are carbs not restricting flow?They have been fully cleaned and rebuilt.
Float heights and ok........
Once running it runs like a dream.
Please help.
