Need some advice, 89 Husky WRK 250 had a delorto unit and is shagged but the bike came with a 2nd hand minkuni flat slide. Motor is soon to go back together once the cylinder comes back from electrosil. Not wanting to damage the fresh engine I want to be sure jetting is close before I start it. If the jets in the minkuni are a similar size to the ones in the delorto will this be close enough?
