I've wondered that myself.....with any dual plug application.

Byron Hines of Vance and Hines fame had Rick Ward (his former apprentice) build a 3 plug head for his 1327cc Yamaha FJ Pro Stock bike. According to Rick it was key to getting the engine to make the power it did. I saw the head from the outside once, total abortion and cool as all heck all at the same time. Think about it, 86mm bore with 3 plugs and 4 oversized valves stuffed into the dome.




Lots of guys do duals on the old KZ heads and 900 Ducati's and of course no one will ever tell you it didn't make more power.

Well.....there you go.

I guess it makes sense in the racing aspect then .........but for a lowly 200X? I better not say no more...... I just found out the new Honda CRF1000 Africa Twin (which I'm looking to get) has 2 per cylinder as well so I know nothing!

On a 200cc engine I wonder what the parasitic loss of powering the second ignition system is VS the gain. The drag bikes run total loss systems, so it’s irrelivant.

That Honda looks like a fun bike!

Doing more work on an Apple IIe that creates vertical bars on the screen for some reason...that and rebuilding the carburetor for my ranger that suddenly started running so rich it puts gas in the oil.

My buddy has the Africa twin. I have a super tenere, they both have their pros and cons, the 21" front wheel on the Africa is great, the s-10 has more power. Any questions ask. He's got 10k trouble free miles on his, I've got like 13k on mine. On and off road miles as well. Super fun bikes, and we aren't nice to them!

I always thought that what may make a dual sport bike better for me personally would be a little more weight....a little more cc and 2 cyliders. However the ADV niche has blown up and so have machines making up the genre. Loaded for bare 650lb off road bikes?

Ironically the AT and the Super T are the 2 bikes I'm looking at. I've passed on the GS or KTM or the Multistrada.......those are boutique bikes to me.

How do you stack up the 2? Full disclosure.......I'm favoring the Honda...mainly for its light weight

Today I'm working on charging system for the FZR. It's not charging at all now. Seems simple enough.........car like alternator.

Thx glamy, good alternative

Yes. We used to replace the brushes on the old Toyota cars back in the day. Looks similar

Well, the AT feels more Moto bike esc, as it is a little skinnier feeling with the radiators mounted kinda like mx bike, the super t has a big tank, with a side mounted rad, ( the cooling fan is junk, if you bump the side panel the fan will go out.) I'm working on alternative tan setup. The front wheel on the AT is 21" super is a 17"(I think) big front wheel is great off road. I ruined the front wheel on mine and was going to convert but it was going to be a royal pain and super pricey. I like both bikes, the super t does have noticably more power, but I wish I had the bigger front wheel.

Ktm was out of the picture for me, as the closet dealer is a few hrs away, I really wanted a gsa, but they are 27k and really huge. And to test ride one you have to fill out paperwork, make appointments, and drive 2-3 hrs just to look at it. I previously had a BMW k1200 touring bike, had a 185k on it when I gave it to my buddy. I would have rode that ugly turd to Alaska. Only let me down once.

Thank you for your insight.

I understand that the AT is down on power compared to the others and way down to the KTM and Super T. But coming from an old 93 DR650 it's going to feel like night and day on the freeway. Since everyone is driving 80mph on the freeway and my 650 tops out at 95 - 97 mph......a pass was always labored for my big single at high speed.........hence why I always thought an extra cylinder and some cc would be nice for the highways.

This is where I'm at with it now. It doesn't ohm out to specs right now and who knows on the rectifier but more than that........I'm I thinking of just getting a used one "guaranteed" off eBay for $100 - $150. Seems easier at the moment.

The AT is great on the interstate. Runs 100 easy

It would be nice to make a clean pass. Top speed is what 120? The Yamaha is probably better than that.
