Bravo man, you did a great job using the parts you had and repairing and not replacing where you could. Well done!

HI Jore!
it's actually very easy when you have the right tool. I have tried with the screwdriver and hammer (to get that center nut out) and it did not work and did a little bit of damage to the nut, nothing major

. I ordered "HONDA AFTERMARKET CLUTCH AND OIL FILTER SPANNER TOOL 20 - 24MM" (20 mm is what was needed) fit that sucker at the end of my impact screwdriver with 1/2" adapter and the nut came right out (hold the basket while loosening the nut with the impact screwdriver).
Once the center nut is loose it's just a matter of changing the clutch plates and checking the plates to make sure they are not wrapped.
Cheers!

Marting100, how hard was it changing the clutch? I'm about to tackle that same job.

The old rigid grips were not doing it for me this summer, went with some smooth Biltwell Kung Fu.

Not much to show... the bike run great....new brat style seat in transit.... I did replace the front brake piston for Mike's
Power Barn lightweight phenolic material piston and 4into1 single stainless steel brake line. Nice improvement, brake seem to work a little better.
Cheers!

Hey Jore! any plan on riding your 400 up North? let me know when you are around, will go for a ride

very nice work so far!!

Jore · « **Reply #32 on:** July 26, 2016, 07:45:46 PM »

Thanks marting100! Not yet, first I have to get it road capable, I would love to visit that area again.

After 1.5 years I finally have my 6A license. (in Quebec it's a pita to get the motocycle license, once the 1st part is done (courses and tests) you can ride with someone that have a full license but you have to wait 11 months before you can pass the final test and get the license that finally allows you to ride solo). It's awesome to be able to get ready and go when ever you want

.
The bike is just awesome for going around town, it's lighter due to all the stuff I took out, probably 15-20lbs less cant hurt ;-)....so much fun!
Cheers!

Not much done except for the fact that one of the card bowl gasket was not installed correctly and needed to be replaced.
Once replaced I did a carb sync and it run perfectly since. (and it pass the dog inspection also ;-)

....so after adjusting the cam chain last year via the upper bolt I knew something was wrong. I could get horse shoe moving because the noise was less after adjusting but this year I decided to change my home made bolt by the one sold @ 4into1. (needed to change the tach and speedo cables since they were not working well even after lubing and decided to order the bolt since it was in stock). I have installed the bolt and I was bottom down with lots of noise. I did a bit of research and open up the breather cap and check via the little holes to see if the chain was slack, and it was. I went and order a new cam chain with soft rivet links and a new slipper. Open up the head this week-end without any problem (just follow the work shop manual). When I got to the slipper holder, I knew there was suppose to be some spring action in there but not in mine. When I pull on that slipper it was stuck a little and when it got out of the hole it was clear that the slipper was not doing is job anymore and needed to be changed (it actually bend on the upper section of the slipper while adjusting since the middle part of the slipper was basically non existing ;-).
From what I can see, I believe the PO never did the cam chain adjustments over the years and the chain go over stretched due to slack. I will replace the chain and compare the length of the new vs old. The horse shoe is still moving and it's for sure damaged but since I am doing the on-frame cam chain job I wont go down there for now and hope it will perform well once I get the new chain and slipper in there. Will see...I will post back the results.

(I also found a video of a guy taking off the head, so I made a screen shot and use it for the head bolts positions ;-)
Cheers

I have break the new chain and the old one (making sure it was secured). Tied the old with the new and rotate until the new chain makes it to the other side.
Linked the new chain with 219T soft rivet and installed the new slipper. I have tested the horse shoe using my cam chain adj. bolt, while leaving pressure on the slipper with my fingers while tightening the cam adj. bolt the slipper was raising up, and confirming the shoe was moving and doing is job. I should have my new cam gasket cover today and I will be able to close that motor, adjust the valve, check timing and while I am there re-synch the carbs.
Cheers!

I have made sure everything was cleaned well, checked the motor bolts for proper torque, installed the new gasket and close everything. Went with the shop manual bolt sequence and torque specs (I did not want to break any bolts so I went with the middle of the torque zone @ 8 n.m.). Proceeded with new plugs (gap checked), Dyna S static advanced timing and the valve gap adjustment. Once all that was done, she started like a champ ;-) nice smooth chain sound. Still need to sync the carbs to make sure everything is perfect for the next run.
I will post a video when it's all done.
Cheers

HI!, it as been a while for me to post anything new here. I am kind of lazy on social media ;-)...anyway, last summer was fun, no problem with the bike except for the day I was going to make the oil change for the winter coming there was no power from the battery. Found the problem quickly seeing the fuse box. Decided to trouble shoot the electrical charging system and after an 1hr or so decided to order everything new. Those parts are old and did their work for 40+ years, time to go with new parts ;-)
Battery, 2 in 1 Rec./Reg., new fuse box from Hondaman (thank you for your great service and part, perfect!), Selenoïd, Dynatek 5 ohm dual ouput coils, Dyna spark plug wire kit.

marting100 · « **Reply #41 on:** May 14, 2018, 10:42:38 AM »

Here's the before and after fuse location. The Reg. was mounted using the same frame bracket, just needed to push it inward and make a new mounting hole to the bracket.
All OEM wires stay the same with good cleaning ;-), plug and play.

marting100 · « **Reply #42 on:** May 14, 2018, 10:49:26 AM »

The Dyna coils were pretty easy to install. I did have to modify the OEM coil mounting brackets by cutting 2 tabs (red ovals) to allow the Dyna coils to sit on those brackets.
Fairly easy to make with 2 cuts per brackets. After it is simple wire connections with new gaped plugs and voila. Just need to take your time ;-)

marting100 · « **Reply #43 on:** May 14, 2018, 10:55:44 AM »

After a few try she started fairly easy. Seem like less choke is needed. Not road tested yet since this was done yesterday end of day with a few beers in me ;-).
I did have a new tire installed last week (the tire was sitting in my basement for 2 years ;-) ...and also a new reverse cone shorty muffler was installed, the sound is awesome.
I will make a short video tonight, pretty cool sound.
Still have a few other things to install.... new front 7" DEL light and exhaust wrap are next.
Cheers!

marting100 · « **Reply #44 on:** June 05, 2018, 07:40:14 AM »

After a short run with the shorty muffler it was clear that it needed to go. The sound is great but there's no back exhaust compression, it's direct, it feel like the bike have less power and makes a lot of sound, too noisy for me and the police I am sure

. Installed the old muffler and went for a few rides. The bike is great! with the new coils and all, the bike start like a champ, equal zip on all band and the spark plugs are very nice. Good electrical makes a world of differences and the bike is so much fun to ride!
I have installed the new LED head light also but I forgot to take pictures...next post

Cheers!

HI! Since my headers were not that nice to begin with and thinking about the heat getting out in front of the bike while the air is trying to cool down the fins and hopefully the oil ;-)
I went with a wrap + clear VHT paint to reduce the heat lost in front. Not sure if it help but I like it ;-)...new LED headlight also installed with GP clutch and brake levers.
Cheers!

When I redone the electrical charging system this spring, I did order a new Alternator wire but was too lazy to install it. Finally did it while drinking a few beers this weekend

. I might have smoke something also since I only took an image of before the wire was changed

The original wire was pretty rigid due to is age and the rubber plug for the 2 wires that go between the motor and the casing was broken. Took the time to clean the Alt. connectors and there goes the new ;-) my dog was so impressed

Cheers!
