sredish Posted February 22, 2004 Report Posted February 22, 2004 congrats on your find. 30mms would be just right. any smaller may not be enough, but any bigger would be too much. Good luck, Scott Quote
Oilsmoke Posted February 22, 2004 Report Posted February 22, 2004 My Son's SHee ( test bed) we installed a set of 28mm Mukuni Flatslide that we got off Ebay New for 189. plus shipping and Man did it wake them CPI's up. Big Time Difference. But it was Not enough for Him. Hence the (test bed) Nick. He as Now installed 34mm flatslide Mukuni Both where the TM model. He have not ran'em yet But plan to next weekend to See much over carbed( my thinking) we are. His Plans are for Pure Hill Shooter only type machine. His shee is Ported & Pohished, Billet intake without Cross over, Reed's are TDR's with Ported stock cage without Vertical center brace, Noss Head 18cc, Cpi's inframes, adv'ed timing plate Lighten flywheel. I can say this It was dam Fast with only the 28 compared to the 26mm stock round slides. Quote
BansheeRider576 Posted February 22, 2004 Report Posted February 22, 2004 definitely ge he 28mm flatslides.. i got pwk's myself and they are sick... you otta get them with clamp n k &n filters tho.. makes a big difference..... don't know what 30mm would be like but 28's are fine for me wouldn't recommend any bigger than 30 or you will get overcarburation.

Big Blue Posted February 23, 2004 Report Posted February 23, 2004 I have the 30mm pwks and like them, just need to get my jetting right now. Quote
Nighty Posted February 23, 2004 Report Posted February 23, 2004 Some time ago there was a complete topic about carbs. and i can remember that it said. The larger your carb is the bigger youre venturi is. (ofcourse) this causes the air to go slower trough your carbs. This had some bad effects. but i cant remember it all that well and i cant find the topic anymore. but it might have been on the rd350 forums the turnout of the article was to only go bigger on your carbs when youre engine really needs it.
