Dunno if that's the way you want to go or you're set on 28 as well. This 25 centre I have set up pretty tight, has pretty fresh carrier bearings too. Sent from my CPH1920 using Tapatalk yeah im keen. im in ambarvale let me know when its ready and how much you want. dyno was a fail as it wouldnt rev over 4500rpm and the dyno operater i dont think knew what he was doing. i think the est has a limit of 4500 so looks like im going to have to ditch it and find an xe electronic dizzy. 1 gerg reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted January 16, 2022 Yeah 4500 doesn't sound right at all, the factory redline is 4800 and my old man's XF EFI could buzz to 5500 or so no probs (but that's TFI, not EST).Sent from my CPH1920 using Tapatalk Share this post Link to post Share on other sites
Andrew Davies 20 Posted January 18, 2022 have odered a msd 6al and keeping the current dizzy for triggering (hope that sorts it out). also going up in jets as shes a bit too lean for my liking 13.5-1 at wot. 2 deankxf and gerg reacted to this Share this post Link to post Share on other sites
Andrew Davies 20 Posted January 22, 2022 pulled the carb off and felt something rattling around inside.... a jet fell out of the secondary (all were loose) now she revs. if the dyno operator had pulled a bowl off he would have found the issue. 1 deankxf reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted January 22, 2022 That sucks mate, but wouldn't that make for a pig-rich top end as the secondaries open? Was that the cause of it falling on its face at 4500?Sent from my CPH1920 using Tapatalk Share this post Link to post Share on other sites
Andrew Davies 20 Posted January 23, 2022 that was the cause of it not reving. have to take it for another run on a dyno with a good operator. 2 gerg and deankxf reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted January 23, 2022 Maybe the rich condition was causing a bad misfire which was showing as lean due to oxygen going through unburned?Sent from my CPH1920 using Tapatalk 1 Thom reacted to this Share this post Link to post Share on other sites
