My buddy needs some help. He just bought a 1985 Yamaha Maxim 700 X with 4 foam intake pods that are shot. Finding out this bike was only made for one year, is hard to get parts. He was looking for the original intake box but can't find one so is getting new paper filter pods. Anyway, they suggest a 25% increase in jet size so we figure it needs about a 130 jet from a 105 stock? Does this sound right to you all? This bike has 4 Mikuni carbs like the CB750's. Paul
I'm thinking they are around 30-33 mm with vacuum diaphram pistons and slinky type springs with the needle jets. The carb top caps are sort of square with 4 screws and about 2 1/2" across. They are much different than the SOHC 750 I have. I know, bad description but I'm thinking he could try the stock 105's, if not, get some 115, 125's and just play with it. The 85 700 Maxim X is an in-line 4, DOHC water cooled. Kind of an odd ball but looks like it would be a good bike.
