Hi guys i was thinking about taking a stock intake manifold and transforming it so that it can fit dual carbs, but i was wondering about the problems such as throttle linkage and cast alluminium welding i asked a few people and they told me i could tig weld another type of steel onto in.Also what size carbs should i run, atm i am running 25 mikuni with uni filter im think i wouldnt run 2 of these it would be to big i was thinking about maybe 2 20mm or 2 18mm carbs. Anybody with expierience or any ideas on this please post them. Thanks
