61X to 1100 Yamaha Conversion for Jet-N-Spray

[RoyalFlush@PCB]

Alright all you triple cylinder swap gurus, I have a Jet-N-Spray with a 701 61X and I have a donor 1100 Wave Venture. Theoretically, shouldn't this be a relatively easy swap using the ADA Racing kit? I have TONS more room between the front of the 701 and the gas tank. I might encounter some clearance issues with the 1100 exhaust and the Jet-N-Sprays hood, but I think that will be easily resolved. Thoughts?

Make sure to use the large diameter exhaust hoses and muffler. You will also need a high pitched impeller for the 144 pump. It needs to turn no more than 6900rpm. Ideally install a 155 unit, that will perform much better. Expect a noticeable increase in acceleration and a slight increase in top speed. If you have no experience doing these kinds of swaps it will take some patience and time to do it well.

I'm considering the 155 pump, as I already have one and the donor ski does as well. Thanks for the tip on the exhaust system!

I used a Solas swirl (16/23 I believe it was) on my stock 144mm pump on my Waveblaster 1100 conversion and it works great. This would be a good option for you if you don't want to swap a 155mm pump in.
