JordyRoo Posted October 27, 2016 Report Posted October 27, 2016 Wondering on best carb choice for a 4mil, 66mm bore, 21cc domes, +4 timing, mild port job, vforce 4. Running 50/50 av gas & shell v-power (99 RON) Currently running 28mm PWKs, is there a better choice? Quote
ClaudeMachining Posted October 27, 2016 Report Posted October 27, 2016 Carbs diameter is over rated. Quote
ginger Posted October 27, 2016 Report Posted October 27, 2016 basically the same setup as mine and i have 28pwks. if you go any bigger you will lose bottom end, and maybe gain a little at the very top of the range. not worth it. Quote
JordyRoo Posted October 27, 2016 Author Report Posted October 27, 2016 Will make a new thread but what about pipe choice? Im currently using FMF gnarlys but im not sure theyre the right pipe for the job... Quote
ginger Posted October 27, 2016 Report Posted October 27, 2016 do you want something with more bottom end grunt, or top end range with a little lag at the bottom. I have SLP's and the bottom end is outrageous, but they do fall down at high RPM. if you want more top, look into a CPI or something like that. Quote
JordyRoo Posted October 27, 2016 Author Report Posted October 27, 2016 Im thinking more top, without sacrificing too much, ive got the vforce 4 reed block. Yeah i think i want rid of the FMF Quote
