Just bumping this thread to see if anyone else has Jardine tuning experience. I've been working out some issues brought on, at least partially, by trying to do things quick instead of right. I got them sorted out and this is where I am at as of today:
-Took the bike over to a buddy's house and had him weld the Jardine to the header pipe. I didn't want to weld it initially, as an aftermarket pipe, but I was not sealing it any other way. Looks good right now- no noticable leaks at header or muffler/header joints. - After trying a couple things: currently at a 55 pilot, 1/2 spacer, and 152.5 main jet, 2 turns (approximate) out on idle mix screw. I've got a noticable increase in power and change in power band. So much so that at times I felt like I had another gear- but top-end aside the major improvement is in low/mid-range. - Backfires have significantly decreased, but still have occasional backfire on decel from around 1/4 throttle. Going to try dropping down to 1/4 spacer and see if it goes away. First, I am going to tape and mark my throttle/throttle housing and see if I can nail down where the lean mix is more specifically. Backfires decrease to almost none with choke out to the first notch. That tells me it HAS to be a lean mix in the idle/midrange circuit. Ideas? - I HAVE CAUSED a shut-off afterfire which did not exist before. Not sure what that is about. Hopefully it will resolve with additional spacer mod. Or I don't have the idle mix tuned right. - Raptor Petcock is installed, and I am running a Uni foam filter. I need to double check the seal at the vacuum ine after replacing the petcock. Right now it is a tube filled with sealant, doubled over and zip-tied shut. Not sure if an incomplete seal there could be causing issues.
I live in San Antonio. I don't know what altitude I am at, but today reflects the info above, and it was cool and clear in the 50s and low 60s F.
