750 Katana Resurrection

[tatu]

Caliper piston kit and headlight arrived (finally). Fitte

The headlight doesn't have a fitting for the park light, but the LED indicators that I have for this bike have running lights, so I'll wire these to the park light out put.

This is an E4 headlight approved for Holland, the dip will be the wrong way, Your original headlight glass is correct as there is no arrow this means it's for driving on the left. I'm pretty sure that it's the glass diffusing that determines where the beam focuses. If an E45, E47, E11 (Or any other Left side driving countries) can't be sourced then maybe swap the glass?
I've just gone through this with my 1000 dirt bike. even in UK trying to get a correct E11 headlight for a bike is a mission.

Here, this might help...

HELLA headlamp codes. Decoding the combinations

[Grimly]

The old headlamp is flat-dip, for the world market. Swings and roundabouts, but on a decent headlamp design it works well.
Unfortunately, many of them weren't very good.

Thanks Guys. Below is from the New Zealand vehicle standards "approved lighting" as per the NZ Transport Agency (Govt).



For whatever reason E4 appears to be compliant in NZ and possibly Australia, which is where the headlight was supplied from.

A further bit of research and it seems the E = meets ECE approvals process and the Country code is for the country that granted the approval. As the ECE regulations are a standard, if one country certifies a particular light, it is deemed compliant in all other counties that use the ECE codes. Apparently the other numbers on the lens refer to the particular ECE standards that govern LH vs RH configurations, illumination patterns and all that jazz.

So... trying to decipher the codes using https://www.hella.co.nz/en/about-us/...-combinations/

• HC/R = Halogen Main and/or dipped
• 00 = ECE regulation amendment
• → Single ended arrow = For Left Hand Traffic
• Circled E4 = Approved in The Netherlands for use by all countries adhering to UNECE standards which includes E48 New Zealand.
• 11960 = ??

So all good for application.

Interesting and confusing, over the years I've replaced a few of the E4 in UK. This might be the reason as Gorminder says. The last one on my 1000 dirt bike was also an ancient E4 that came on the bike (bought as a breaker because it was so horrible) I can't remember which way it dipped now, the chrome had lifted badly is why I changed it out and really had to hunt to find the correct E11.

Good news, I like your clear look headlight, it looks much better than the one on my Katana. Also good news because the clear looking halogen one on my DR200 also an E4 that is on it's way to UK is probably the best headlight I've ever had on a bike.
As an aside I used one of those cheapo ebay LED lights on my CRF (who's headlight was completely naff) and the light those things chuck out is amazing

Very impressive work, especially the frame straightening. I worked in a truck coachworks and my main work was straightening truck chassis after an accident. Your doing great and waiting on next instalment.
Dennis.

Thanks Dennis. New Zealand, or at least Auckland is coming out of lockdown, so I'm back at work and have less quality time in the garage. Got some brake fittings on the way to get everything connected. I want to get both systems working so they come off the list and I can feel the rolling chassis is more or less finished with all the wiring in place, tested and working. Then I'll turn my attention to the engine and bodywork. I've decided I'm going to paint the engine black and the body work Tiger Mica with blue and white detailing. But that could change.

Brakes bits finally arrived and so did a screen or two. Wiring back on the frame and waiting for the coils to arrive











Apparently the screens are ABS, and seem very sturdy. Don't know about scratch resistance yet. Time will tell.

Just waiting on the rear brake reservoir. Everything else tightened up. Frame rails protected. Engine next.

Thanks for your kind words, Ed. Appreciated. Much of the learning is in the doing and hopefully everyday is a learning day.

May I ask what size and the kind of tires you're using? They look like they would work really well. I need a new pair for my S.

Hi there,

The tires are Shinko SR712 Bias ply Sport Touring tire. The front is a 100/90H19 and the rear is a 110/90H18. Which is the closest to the 4.00H18 fitted OEM, although the tech sheet lists a 120/90H18 as an alternative for E22 West Germany.

The rear rim is a skinny 2.15x18 and usually I would have fitted a 120/80H18 (the widest tire for that rim). The 110/90 is an experiment. Want to see what effect it has on the handling, which is more important to me than the grip and tread that I or the bike will never make use of.

I like the 712s but remember they are only H-rated, and V tires are usually specced for litre plus Suzies. I have them on my 650G and done 10,000km (6,200 mi) and the rear needs replacement. The front still half worn but still has good profile and still stays neutral (enough) when trail braking. RevZilla did a review which is pretty much on point https://www.revzilla.com/common-trea...12-tire-review

Rear 130/90H17 on the 650G Katana


Front 100/90H19 on the 650G Katana


Confidence inspiring grip, reasonable wear rate and cheap. What's not to like?
