First off - Thank you all for your knowledge, advice, and tech docs. I've on week 8 of my 1983 Venture project. You can't place a price on the critical this forum has been. Full Disclosure - My previous motorcycle project was a few years ago on a 84 GoldWing that I literally found in a barn next to cattle. It had been there for almost a decade. The PO won it a poker game, but didn't actual ride motorcycles, so he parked in the barn and left it. The only reason he found it is because he built a new barn and was about to tear it down. So a little history of the bike as I come to know it. 83 VXZ1200 - 33K miles; Been sitting for 8+ years. I found it in a trailer park in KY. It was in pretty bad shape. Probably worse than the GoldWing, but all the parts where there. Even got all the plastics. Sun faded, cracked and in pieces, but they were there. So this is the kind of project that is right up my alley. I get it home and start going through it. Engine would crank, brakes were shot, carbs were broken - no just clogged - physically broken (how in the world to do you even break a multiple carb bodies!) and the gas tank looked like someone poured a bag of potting soil in it. I've never seen a gas tank with 2" of solid gunk. The bike did come with brand new tires and a service manual. I'm thankful for both. So far I've: Replaced the carbs with a set I got off eBay that came off a 1983 XVZ1200. I did clean and rebuild them. Set each idle screw to 2 1/4, re-synced with Motion Pro II and Vacuum Gauges. Cleaned the gas tank. That took several hours with pressure washer and at some points I had to take a hammer and long chisel to break that gunk free. All new fuel lines and a clear see-through Advance Auto Universal fuel filter (so I can monitor it). FYI - it actual fit holder by the fuel pump New spark plugs. Autolite 4164 gaped at 35. I didn't replace the wires, but I did clip the wire ends at the coil packs. Strange enough - the previous spark plugs where gaped at 23 (instead of 32). Clean the wires to the CDI module. The coolant was bright green, I flushed it anyway. Just a normal water flush (no chemicals) and I went back with the normal green stuff. Soldiered the CMU, fixed a broken soldier on the hazard switch, install the battery bypass resistor Fix H4 Headlight connector - somebody switched the hi/low beam wires (just why??) Upgraded the fuse box to a new blade style fuse box. I had to do it. The PO had remove the old fuse box and crimped the wires directly to the blades of the fuses! The brakes where already separated and the rear master cylinder just needed a good flush. Rebuild the front master cylinder, installed brand new brake lines, along with new brake pads all the way around. Rebuild both front calipers. Spend close to 40hrs just repairing the plastics. They look okay. Yes, there are some hidden zip ties in certain places. Installed a really neat stereo and speakers that sound amazing. Crystal clear even at 65mph. (I'll save that for another post) I've changed the oil three times so far. I believe consecutive oil changes in close session is the safest way to clean engine. I stay away from all chemical engine cleaners. I also installed one of those USB ports that has the voltage read out. That voltage readout comes in very handy. Repaired the 3 white stator wires. They were actually twisted together, duck taped, and shoved in the gap by the tank. two of the wires had came loose. I soldiered the wires and used two lays of heat shrink tubing. I do believe that the list I may have forgotten a few things. Had some major headaches and long nights along the way but that was due to lack of maintenance and overall lack of knowledge of the bike itself. I also took plenty of pictures along the way. Kinda like a small photo journal. Overall - This bike is a monster!!! I've never ridden anything quite like it. I would have never imagined it would have so much power. It rides like a dream. It has totally exceeded my expectations in every way. My wife likes it way better than my GoldWing and so do I. I'm a true cruiser, I shift between 3-4000 RPM's. Little did I know how quick this bike gets to 3000 RPM. You barely have to twist the throttle. I took it out one night and really got on it pretty hard... totally different bike. It was like riding my Kawasaki Concurs. I swear the front wheel came off the ground at one point. I'd like to meet the individual that has actual went WOT. I tried - I almost hit 80MPH is second. Scared me a little bit. Shouldn't be able to do that with a full bagger LOL! I'm still learning the bike, so I catch myself trying to kick into 6th gear every so often. But it felt safe and it didn't fade or shy away. So yea, I'm totally sold on this bike. I'm truly impressed and I'm glad I own it. It was definitely time and money well spend. Okay - so to the issue I need some help with. This bike starts great, runs like a mad bull, no pops or pings, no back fires, no warning lights, and runs pretty cool for what it's worth. But I have a strange issue when I come to a stop. The idle will drop and the engine will start bogging down. The tach falls to zero and doesn't move. It will eventually bog down low enough and die. Previously it did not do that. It idled at 1000 and didn't budge. I can play with the idle screw and get the tach to bounce between 1000 and zero (even the engine rpm is steady). Now it will idle at 1500 rpm just fine, but that's way too high for my taste. I have no drive-ability or ride-ability issues. From the point you take off to the point you come to a stop, the bike runs flawlessly. It's only when you squeeze the clutch it will drop. But not every time. Some times you will come to a stop and it will idle right on 1000, then a few seconds later the tack will drop to zero and it will start to bog down. As soon as you take off, it's like nothing ever happened. I've ran a can of seafoam through it. I've reset the idle screws, I've check the sync on the carbs, replaced the plugs again, replaced the fuel filter again, adjusted the linkage cables, cleaned all the grounds, charged the battery, drained the tank, and changed the oil (4th time). Went though an entire can of carb cleaner, searching for vacuum leaks and didn't discover any. There still may be a vacuum leak, but I just didn't find it somehow. Checked the carb slides and diaphragms. It has gotten better. I can find a sweet spot on the idle screw when it warm and it will not die. The tach will be still be at zero, but the engine sounds like it is at 1000 rpms. I can't figure this out for the world. I have rode a total of 516 miles since I put it on the road. This issue didn't develop until I ran seafoam through it around the 300 mile point. I took the bike out tonight and rode 60 miles on the highway at 70mph. it rode like a dream. Shifted perfectly, temp gauge was a little above half, voltage stayed between 13.8 and 13.9 (thanks to that little gauge). It was quite and smooth but the issue was still there when I came to a red light. It didn't die, but it did bog down and the tach went straight to zero. Any advise would be greatly appreciated. -
my 86 is being cranky again... Went to start her up and she didn't want to start. Finally started but wasn't running so hot. Noticed the RPM gauge was at dead zero and not even twitching. when I rev it... the RPM gauge takes a second but finally comes up. I took it for a quick spin and even at higher speeds it's bogging with out much power and also when it does bog... the RPM gauge goes back to zero like the bike is off. Then the RPM gauge will come back and it runs normal again. Kinda goes back and fourth from running fine to no RPM's and not running fine. HELP!!!! my baby is sick! hahaha... thanks in advance! -
seeing as i hope Dianne dont come on here and read this? its a nice in the 80,s day and im feeling pretty darn good. so i thought hey oldgoat take the venture out and see what dianne was talking about it bogging down. well i fire her up and take off. first i made some phones calls to family and friends and gave them my route i was going to take.. well off i go. im going along nice and steady. then theres a 45 degree uphill road. ok heres a good place to test the bogging?? i crank it up to 45mph in second and just hung on to the throttle. shot up that hill hitting 60mph in second maybe not a good thing? hit the flat top road hit 3rd and cranked it again and hit 75mph.. the i just dropped it into 4th. and stayed there. never put it in 5th. as this road is a 45 mph road and its getting close to the end of the month .can we say this road is a speed trap road because as soon as you hit the bottom of this road it drops to 30mph. small town about 125 population. well im thinking that that number 3 sparkplug cap i cleaned and snapped back on migh have something to do with the bogging. they had and now i fixed it?? also the seafoam and premium gas might have finaly cleaned something in the carbs?? so i had a good day untill i got home and noticed oil burring smell?? i think i have a small vale cover leak on the front left side as i see some grim and oil residue there?? not a biggie. just might need a little tighten down on it. also noticed that left handle bar seems in a little? now i think that the repair shop dropped another bike on mine. as the farring was cracked. so is there any punch marks on the bars to see if it it shiffted? or god forbid its bent some. im thinking this is what makes the front wobble some? im trying to ride and keep bars straight and im pulling the left bar when i shouldnt??
