A parcel arrived today.

A set of new Mikuni RS 38MM flatslide carbs for the project Kat. Not only would they be helpful in providing some get up and go, they are an amazing looking bit of kit and could well be considered Art!

Lovely stuff. ............

Nice carbs, but maybe slightly too big for your engine. I had 38 Mikunis on my 1296 cc GSX and they worked quite well. Then I swap the engine to 1360 cc and now the carbs are working perfectly.
I think the 34`s would have been better for you if you are not going to racing.

Yes, maybe 34 mm flatslides would suit a stock 1135 and I know some who are running those carbs on their Kat. However, fitting 38 mm flatslides is not unusual with the 1135 and over engines in my part of the world. My engine will be running a set of 4-1 Yoshi 60 mm pipes with a 60 mm muffler, Yoshi cams, adjusted timing, velocity stacks and to get it sweet the carbs will be set up using an O2 sensor to sort out the jetting.

Right now the Kat is running with 36 mm CV carbs with 160 main jets and it is running strong.
