men3cac Posted March 13, 2014 Share Posted March 13, 2014 Hello all. I'm considering changing my motorbike throttle bodies for Jenveys, preferably 45's, for a zetec. Anybody got any to tempt me with? Thanks Craig Link to comment Share on other sites More sharing options...
stu999 Posted March 13, 2014 Share Posted March 13, 2014 Purely out of interest...why do you want to swap MC TBs for Jenvey TBs? Are the MC ones not large enough bore? Link to comment Share on other sites More sharing options...
men3cac Posted March 13, 2014 Author Share Posted March 13, 2014 Mine are a bit on the small side (38mm) and I'm struggling to get rid of some play in the linkages. It's giving me an annoying flat spot off idle where #1 goes lean before the TPS notices! Link to comment Share on other sites More sharing options...
ALLADDIN Posted March 13, 2014 Share Posted March 13, 2014 38 is plenty big enough, the flat spot off idle is a mc tb trait but can be mapped out. Check out posts by fatbaldbloke, Ian. Or find his website. What ecu do you have ? 1 Link to comment Share on other sites More sharing options...
men3cac Posted March 14, 2014 Author Share Posted March 14, 2014 I'm running on microsquirt. I was checking FBB's website but he's taken it down now, but I'd borrowed a few tricks off it before he did. I'm not 100% happy with my manifold so I was considering a new one (which should help some of the issues I'm having), but I thought I'd see if there are any Jenvey's etc going cheap before I got too stuck into it.

Paul Morcom Posted March 14, 2014 Share Posted March 14, 2014 I have a set of Jenvey 40s and air horns that I will part with. No other parts or injectors. The 40s are good for c200bhp. Jenvey part numbers - TBP40i and AH 45x60 The are hardly used - 3 months on my sprint car, which actually means less than 100 miles! New would be TBs - £470 and Air Horns - £120. I would take £350 plus P&P for the lot. Link to comment Share on other sites More sharing options...
men3cac Posted March 16, 2014 Author Share Posted March 16, 2014 Thanks for the offer Paul. Having looked into the prices of the other parts required (and I'm still struggling to find a 40 DCOE manifold for a zetec) I'll give it a miss. If I can't find any cheapish 45's I'll persevere with my GSXR ones. Link to comment Share on other sites More sharing options...
