Re: Bucky's '74 CB360 Hardtail Bobber Build

Got all the electric starter parts off the bike last night. Brought the ac generator into work today to remove the starter clutch housing. Got 1 out of 3 off with out having to use a screw exctractor... Damn those philiips head bolts all to hell!!!

Now i'm just waiting for the starter block off plug I bought off ebay, and my new gasket. Also got my new stainless button head boltse yesterday.

Test fitting the velocity stacks.

Re: Bucky's '74 CB360 Hardtail Bobber Build

Received my starter block off. But didn't go with out a hitch. Went to install it and sheared the I ring in half. Has this happened to anyone?

Re: Bucky's '74 CB360 Hardtail Bobber Build

Should I of lubed the plug/ o ring before inserting into the hole...

Yeah. A light coat of grease on the plug/o-ring and the hole will help.

Do those velocity stacks have filter material in them?

Thanks,
The velocity stacks will have a screen and prob. Some sort of filter element inside maybe a some UNI filter material. Thoughts?

Re: Bucky's '74 CB360 Hardtail Bobber Build

So I got some 4 new o rings, tried with grease and oil neither worked. Upon further inspection I noticed the o ring on the plug is sitting out further than my starter I ring. So I'm thinking the o ring landing want not machined deep enough.... Hopefully this can get sorted quickly. Not than I am any where near riding. But I'm impatient, and I want shit to just fit, when I purchase it. Ok end rant, just mildly frustrated!!

Here is the difference between the two

Crazypj makes the proper 360 plugs. So, send him some cake and get your money back for that POS . He probably has one fresh out of the lathe just waiting for a shipment address. Also, may ask him about the other things he makes for the 360. You may need to place a full order.
Hes sending his MKII tach plug out to me today.

The o-ring on your starter is worn. Thats why its thinner. Clean the grease off and stick the plug with the ring on it in the freezer overnight. Regrease and try again in the a.m.

As far as the stacks...

You NEED to figure out a way to add filter material. Just screens will not stop most dirt and dust from being sucked into your carbs and likely causing damage. Stacks are generally a bad idea on street bikes as they can negatively effect the bikes air/fuel mix throught different stages of the rev range. That and the lack of proper filtering can lead to some nasty shit ending up inside the carba and motor. They definitely look rad, but not all race parts should be used on the street.

Re: Bucky's '74 CB360 Hardtail Bobber Build

I will give the freezer trick a try. Hopefully that will help.

I measured the o-ring grooves this morning. and the plug inside of the groove is 1.721" and the starter inside is 1.682". I'm thinking this might be a contributing factor in it not fitting. :-\

I appreciate the input on the stacks. I'm not completely sure if i will use those stacks or not. But If i do, I will for sure put a filter on them.

Re: Bucky's '74 CB360 Hardtail Bobber Build

Got an email back from the manufacture, they are going to send me a new plug. This one has a smaller ID on the o ring groove. 1.71" hopefully this will help.

Looking on ebay for a master cylinder/clutch for 1" bars. And came across allot of good deal on Harley take offs. They are 9/16" master cylinder. Will this work with the CB360?

9/16" master cylinder bore is equal to a 14mm bore. Factory 360 master cylinder is 12mm. I suspect using a 9/16" master cylinder will fling you over the handle bars. :-\

mmm.. Might have to look more into this. I was looking into this a while back. And from what I read. The bigger the bore, the harder it would be to pull the brake lever. I don't think the bike would stop and better/worse. I would just have a different brake lever feel... Anyone? Is this correct?

Just ordered my new tail light.

Once I receive it (suppose to receive it tomorrow!!) I will design up a plate/light bracket. Then send it off to the laser table.

My welder got most of the frame done this weekend and seat mounted. Now just need to mount the tank,rear fender & electrical box.

Still need to figure how how much/little rear fender i want.

Re: Bucky's '74 CB360 Hardtail Bobber Build

No...

The bigget the bore the greater the pressure exerted on the pistons, i.e. greater stopping force. I've ridden ultra light vintage bikes with modern front brakes and they will stop you in your tracks before you know what happened.

Some folks will purposely bleed air into the system to "soften" the response. Youre better off just getting the correct size master for your application.

Thanks for the explaination... The PO, must of put a replacment master cylinder on it then, it has a 13/16" MC installed. ???
Off to look for a 12mm MC.. Thanks

If I use the stock caliper, but a modern master cylinder. Do you get the same effect?

A modern 12mm master will work just fine with the 360 factory caliper.

That looks great! I would have to move the seat back, but that's just personal preference(plus I'm 6'1").
