Yamaha YZF750 Troubles | Budget Bike Battle Bavaria

[@FortyFourTeeth]

Thank you for all your suggestions in diagnosis from the last video - well done if you mentioned the EXUP valve, buy yourself a Cornetto. BUT - Please stop saying we ignored your comments - this video was shot before the other videos were even broadcast - therefore, we couldn't possibly read the comments, because they didn't exist! Also, it wasn't the EXUP valve itself, that was operational - it was the cables which stretched and broke over time, hence why it was not so obvious. Many other little jobs which were well worth doing were also completed here so nothing was lost. Much Thankings 🙏

Glad its sorted ps it looks so much better than the fireblade xxxx

Totally understand the sentiment, it makes perfect sense, but at the same time don't disregard the intentions of people that were just trying to help, and were maybe over excited to do so because they care. (F*ck any smug haters). Peace out. Up the Baron looks like he proper put the effort in.

A thought about that original rusty old plug you removed, are the drain holes at the bottom of the plug recess blocked. Mine were when I bought a 26yo RF9 and number 2&3 plugs showed similar heavy rust staining, causing a major misfire in the rain, something you will run into during an autumn trip in Barvaria, but glad you've got her running sweet

First time I've seen a digital carb synchroniser. Didn't even know they exist, nice!

[@hetistijmen]

Quick trick to check the coils: feel if one of the exhaust headers stays cool longer than the rest. If it does, swap around the coils and leads (swap connections to the CDI as well) then feel if the cold pipe heats up faster. If it's running on 3 and each pipe heats up the same, your misfire is jumping around. If it does change your cool pipe, change the coils back but keep the leads swapped. Then isolate to coil or lead.

Admit defeat, call International Rescue. So the misfire was an unconnected EX-UP valve? Did you replace the crappy old fuel filter(s) which probably had a load of crud in them?

[@alanconway8821]

I knew it would be the exup valve! When I got mine it was by passed by being cable tied open, servo and all was in place and working just bypassed. Hooking up the exup valve gave it way more low end. Before it was a constant battle to stop it stalling pulling out of junctions but now on idle you can drag the clutch. A great little machine

[@muirjs]

Absolutely loving the positive vibes throughout, despite all the shittery!

[@Wasagoodyear-qf8wj]

If you got an airline handy, it pays to blow out the liquid or dirt in the spark plug recesses before taking the plugs out. It stops all the grit, shit and water from falling inside the cylinder or threads and causing further problems......Exup valves are notorious for seizing up too and should be one of the first things to check is working on an FZR or YZF. Most of them are seized, disconnected or deleted on any cheap bike nowadays, The EXUP principle is the same as the YPVS system on Yamaha's two stroke bikes and affects performance in the same way. I think that the YZF is notorious for burning oil too, so make sure you got a litre with you. I've always fancied buying a cheap YZF750 or Blade to play with and this little series has been good to watch.

[@gixerloon]

Old bikes are great when they've cared for, but years of neglect by hapless owners and you get this outcome, and just why the EXUP wasn't connected 🙄 unbelievable, glad you got it fixed... James "you da man" that was a great tip about using copper plugs over Iridium plugs. 👍

[@nickrider5220]

Thanks Chris, you've made it a nice Monday evening 👍🙂

[@DoRC]

If done properly with a high quality tank coating you can get a really good result. The problem that people run into is they either use cheap coatings, don't follow the directions or most often don't prep the inside of the tank properly before using it. I've saved multiple garbage tanks with tons of little rust pinholes in them with those coatings and they were still going strong years later.
