1st gen t3. whats difference between flatslide and round slide carbs?

[kokmatt]

just as title says its my understanding that 85 tecate came with flatslide and 84 with a roundslide? is this true? which is better and why?

[dcreel]

The 84 and 85 Tecate's both came with a Mikuni VM roundslide carb. The 84 was a 32mm and the 85 was a 34mm.

A flatslide carb is better than a roundslide carb. The flatslide has better throttle response and flows more air vs the same size round slide carb.

The 86/87 Tecates did not come with a flatslide carb, it was a 34 mm roundslide as well. The difference with the earlier carb was the bottom of the slide which--if memory serves me (it is discussed in my service manual)--they called an "R" slide. It is supposed to get better throttle response off the bottom.

ok thanks guys. there is a flatslide carb on the parts bike i have so think im gonna clean it up and put it on and see what kinda difference it makes. pulled carb off of my parts bike and it is a keihn flatslide. would this be the better choice for my bike? it has aftermarket pipe and reed valves so im hoping this flatslide will help out also?

also what cable do i need to use to make this carb work it is a keihn pj carb 35mm i think. is this too big since my stock one is a 32mm. stock tecate cable does not fit on this carb?
