TJS Posted June 5, 2023 Share Posted June 5, 2023 Factory Pro is now making FCR emulsion tubes with holes. Felt more responsive by seat of the pants and right hand! Quote Link to comment
djayedot Posted June 21, 2023 Share Posted June 21, 2023 I always wondered why FCR engineers decided to omit the mixture holes in the emulsion tubes (also always wondered WHYYY the hell there's only bearings in 3 out of the 4 slide wheels). Were any major jetting adjustments required to make these run right? Also, as a side note since I'm considering upgrading carbs soon- would you happen to know if anyone's figured out a decent way to run proper filters over FCR's with the velocity stacks still intact? Maybe some kind of base plate behind the stacks for filter mounting? Quote Link to comment
Gixer1460 Posted June 21, 2023 Share Posted June 21, 2023 Re : tuning them, not a clue but i've a set of 41's to do in the future. But the airfilters - thats easy . . . . . use the oval foam pods from RamAir or similar. They stretch over the stacks easily and will be retained by them. A light coat of filter oil will improve them markedly! Quote Link to comment

TJS Posted August 14, 2023 Author Share Posted August 14, 2023 Still haven't been able to get a dyno run. Finally made it to the track. I did go up one size on the main jet too. Weather was 96 deg F with high humindity and heat index over 100. Quote Link to comment
