Dodgy DIY Smog block plate
4 Attachment(s)
This morning I fitted up the carb for the first time since putting the 351 kit on and tried starting the bike. It did crank over and I could head there was compression (unlike the old top-end) but it didn't fire. At one stage I heard a pop so thought I was close. But then I noticed a few drips of oil on the floor between the front wheel and engine and freaked! On closer inspection the oil was coming from the Smog opening. I bought this head off Adrian in the UK where they have the smog stuff, and I didn't realise that coz my Australian bike the opening was blocked off. I had plugged the holes in the smog opening with some exhaust cement but obviously that wasn't strong enough. I know one of the mods recommended here is to put a blanking plate over the opening. Problem is that I don't have the equipment at home to make a plate up. But I saw someone on here had basically made a blanking plate out of the smog plate by sealing off the reed valve. So that's what I have done.
First step was taking the smog reed valve apart and cleaning all to soot off it: Attachment 9407 I managed to find some JB Weld as it seems to be the preferred goop to do any sort of serious sealing work on this forum Attachment 9408 I then straightened (actually I almost reversed the curve to it would push the end of the valve closed) the reed valve stop so that it won't let the flap open, but I didn't that on its own won't make a good enough seal. So that's where the JB Weld comes in - I JB Welded the valve to the plate and then screwed the reed valve stop back on. Attachment 9409 Next, I found the right size bolt to plug the smog pipe connector then tapped the hole out before screwing the bolt in with a bit of loctite: Attachment 9410 So that's the blanking plate "solution" ready for installing: http://i629.photobucket.com/albums/u...ps287494a5.jpg I've just got to give the JB Weld a few hours to cure before installing the plate. I also need to figure out how I'm going to put the plate on without removing the head again. Hopefully I can, although I predict I will be losing some skin off my hands and finders in the process and no doubt make a blood sacrifice to the DIY Gods :D I think I'll also put a new spark plug in just to take that out of the equation of possible reasons why the bike won't fire. Who said this job was going to be simple? |
Accck!...how barbaric!:D
Very creative. Threading the smog hose barb was a nice touch. |
I'm waiting to hear how she runs now......
Nice job, barbarian! I have yet to use JB Weld. Carry it around with the KLX, yet no one has needed it. Knock on wood as they say. Who ever "they" are. . |

Just finished up putting the smog blanking plate on and it wasn't as difficult as I expected
Attachment 9406 I slapped in the new spark plug (coz I had it already) and did the check to make sure it had spark - it was a good spark. Once it was in place I pulled the choke and hit the button for a second just to get an initial turn and it nearly fired straight away. The second hit of the button and she was away! I pushed the choke in fairly quickly as it started revving faster almost immediately. Even after putting the choke in she was still idling a little fast so I adjusted the idle to get it to a more reasonable speed. ROCKIN!!!! She lives!!!! :D |
Nice job on the threaded plug. Way better than a vacuum cap and more permanent. With that plug in there I doubt the JB weld/reed valve part of the job is doing you any good.
I have used JBweld twice in my life with great success. Once to repair a cracked fuel bowl on a diesel tractor, worked for years, and a second time to hold the trailtech magnet onto the disc brake rotor for my vapor and it has been solid. |
High beam is correct. The threaded bolt on the air inlet is adequate. Maybe overkill..;)

Hey, the JB welded reed plate is just belt-and-suspenders...nothing wrong with that...LOL!:D
Has she "blowed up" yet from this barbaric DIY disaster, Arctra?:D |
