Today have I test mounted the new exhaust, it looks to fit perfect. I have now packed down again and will sent it coating tomorrow.
I will properly not be able to install it before I take the bike out from the storage room in April? I`m afraid of damage it when it move the bike out :)

These weekend have I balanced my wheels, last winter I replaced the tires without balancing the wheel. I have had some vibration when I have driven... not so heavy that I have done something with it... hopefully is that away now... will be interesting to drive when the season start and see how they perform.
I also did some easy polishing on the rims.

Today have I installed washers on the front fork suspension between the progressive spring and the top cups.
I have missed these part...

I also took some measurement on how much the progressive spring is pushed down when there is not weight on the spring (lifted up the frame in the front).

I have never liked the front fender, the way its mounted to the bracket with 4 bolts and nuts....
I found a new fender on eBay from a kz750 1981 model, I have sanded the fender primed and painted it with new black color.
Sprayed some body spray (dry) to avoid corrosion in the inside of the fender.

I absolutely liked the results, much more clean design "follow" the wheel better...

One task left on the fender I need to make some more space for the brake lines, so they don`t damage the paint when I use the bike.

I've never seen a fender like that with fasteners on top. so then I checked partzilla & sure enough, that's how some were done. weird.

I have had problem with the brake lines touch the mud cover, I ordered some spacers on eBay and painted them black, I think the problem is solved now.

I have gotten some help here:

Today took I the bike out for the first time from winter storage, spring is here now :)

I installed the new exhaust system, happy with the results. I also flushed the gas tank with new gas (have stored it with WD-40).

Looking forward to start up the bike with the new exhaust system, maybe tomorirow :)

I damaged the spark plug threads on cylinder 2 some days ago, have got some help here:
kzrider.com/forum/2-engine/610761-damage...eads-to-spark#804935

Today was I at the mail office to get the Wurth timecert kit I have bought for a good price. I don`t know if Wurth is common in US? In Europe in stand for quality parts...
I diden`t had any problem using it, and I think the results is quite good. The insert could have been longer, you can see it from the picture, but I have now threads from approx. 80% of total.

Fun to be able to fix things self :)

Next Friday is the plan to take a weekend trip, stop working after lunch and drive rest of the day and Saturday and Sunday, a road-trip :)

Wurth aka. Würth is a German Automobile tool and equipment supplier.

BTW: In German language the letter ä = ae / ö = oe / ü = ue are so called special spoken vocals and the German grammar is more complicated.

Last winter was I rebuilding the engine (pistons / valve mapping / etc...), so I wanted to check the valve again, to make sure they is within accepted limits.

May 2018 (536792km)
1 - 0,10 - 0,15
2 - rundt 0,18
3 - 0,10 - 0,15
4 - rundt 0,18
5 - litt mere enn 0,10
6 - litt mindre enn 0,10
7 - rundt 0,18
8 - 0,10 - 0,15

Today (560812km)
1 In : 0,18 (2,80)
2 in : 0,14
3 in : 16-17
4 in : 0,14

1 ex : 0,14
2 ex : 0,14
3 ex : 0,16-0,17
4 ex : 0,19 (shims 2,40)

After reshimming in 1 and aux 4):
1 in : 0,11-0,12 (shims 2,85)
2 in : 0,14
3 in : 0,16-0,17
4 in : 0,14

1 ex : 0,11-0,12
2 ex : 0,14
3 ex : 0,16-0,17
4 ex : 0,14 (Shims 2,45)0812

Now I plan to follow normal km interval for valve check, agree?
