Make sure the resistance of each plug is 5k. I had a back fire issue on my cylinder 3 and it was due to my plug resistance being 20k and not 5k Took me a long time to find the issue

Thanks

Sounds like you will be the 750cc guru once all this is finished. I’m sure it will be worth the effort. My local mechanic wants me to pay him 169 AUD an hour so I’m trying to learn and do as much as I can

Thanks. I’ll checking timing. I’ve never done it so something I need to learn.

Thanks. I synced carbs about a month before I pulled the carbs out but I can try doing it again. It’s just a bit confusing why the bike went from running at 75% ok on one bad plug cap to now choking up.

Hi Did you resolve this. Did you check the impedance on the spark plug boot . Should be 5k. I assume you have spark. I had a back fire issue which was caused by a boot with 20k ohms

Hey Old Crow, I’d really appreciate some advice on my 750. I just put the airbox and carbs back in (what a pain) Bike was hard to start but eventually fired up and seemed to idle again for 5 minutes so thought I’d ride around the block. Didn’t take long for the engine to start coughing and...

Well I got 20 years old mate then yes probably

Ok thanks mate, I’m restoring a couple C110s to my skills up. I did an electrical fitter trade back in the last 80s as part of my 7 years in the Navy as a weapons mechantic (also did 6 months in San Diego leading the 5 inch gun) Then the last 30 years as a Tax Accountant lol So I know I can...

On the tank No I have had a few issues getting carbs to balance. Guy I bought the bike off didn’t really know much. I’ve been learning a lot and I refuse to take her to the bike shop. Should be back on this weekend

Cool mate Looks really good. Opposite seasons down here in Brisbane, Australia so getting into winter now. That tank damage was painful to look at. Ouch! Lucky it was above the engine line. Did the HONDA logo badge on the tank come standard on that model. My 81 just has the decal stickers and...

Firstly, forgive me for this not being specifically about our 750 DOHC bikes but I’ve recently started putting a bike together for my 15 soon to be 16 year old son. I chose the CT110 (Postie bike in Australia) mainly because I’ve never really done a full restoration and these thinks are probably...

Yes I completely understand. I bet you were in the dog house for a month. 750 reasons id still pick her instead of the crazy ex.

Thanks old mate I’ll put the airbox back in. These 750s are very sensitive. I can almost hear her swearing at me lol

Air POD filters

I’m having similar issues after putting on airbus filters bike ran ok for first 15 minutes but now it’s all over the place. I’m putting the original airbox back in.

Nippon Performance Motorcycle,Deshon Street Woolloongabba. It’s not cheap though. I think paid $19 a metre but I couldn’t find it anywhere else.

Hi Has anyone had issues with these installed. Specifically carb problems Idling all over the place Hard to start. I have reset the pilot screw adjustment to 2 turns (wish I hadn’t of messed around with at all tbh) First time I rode the bike with new air filters the bike ran well for about...

Should I get a Patent on this😁

Hi, first post. Bought my 82 750 in February and at the time it was back firing on cyl 3 I found I had 20k resistance on number 3 plug cap. I’ve changed all caps and put in new HT cable. Burnt out a starter solenoid in the process but all fun n games and I’ve learned a lot. Bike no longer...

I’m in Brisbane. Can anyone advise where I can buy copper core HT wire either in store or online. I’ve looked online but no luck. I think cable is 7mm
