Nice job! Looks great. Interesting tires, what size are they?

thanks they are 4.50-18 on back and 4.00 - 18 on front. Hardly any clearance on the back

Re: Cl360 "vader"

Mikuni Fine tuning questions..... I have been putting a lot of miles on the 360. I recently changed my mufflers to one's with a bit more back pressure and have felt like I was running a bit rich due to gas mileage and smell at idle but no black smoke. I fouled a spark plug on Sunday. So today I changed my idle jets from 45 with air screw all the way in to 40 at two and a half turns out. It ran decent at first run. My second run 30 minutes later with no changes it began backfiring at the carbs and did not run well at all. So I put the 45s back in and after starting realized that I had fouled the other sparkplug with the previous 40 since it never sparked with the 45 I just put back in. So........
Now I am back at 45s with new spark plugs and running good for now but hoping I don't foul them as I did a few days ago since I am back to my original set up that fouled. Another note, compression is good, timing and valves are set properly

Questions, some probably dumb:
1. Lower number on the jet means leaner/smaller right?!?
2. A 40 at three turns out should be close to a 45 all the way in right?!?!
3. Is it normal to foul a spark plug every 500 or so miles on these 360s?

1. Yes
2. Hard to say, but anything outside the 1 to 3 turns and a new jet is required.
3. No, not at all, setup correctly you shouldn't be fouling a plug at all.

By the sounds of your description the 40 is the better idle jet, anything outside the 1 to 3 turns and a new jet should be installed. So put that one in and dial in the screw as described in the manual to get the best idle...then forget about it. Move on to the other circuits of the carb, sounds like they need the work.
 
before changing pilots check and see if you have a air correction jet in the 6 oclock hole in the intake side of the carb

if so try removing that first and see if that leans it out enough to cure the problem

Thank you guys I think I got it running good.... That is until the temp changes and winter rolls in.

Re: Cl360 "vader"

I want to increase my top speed. What would you guys do and in what order. I am going to order a smaller front sprocket. I have pretty much stripped everything weight wise. Other than the sprocket and me never eating again what can I do?

Weight doesn't affect top speed. Eat all you want.

Other than gearing, you're going to need horsepower.

I am not a professional but, weight is integral in the weight to horsepower ratio. To use and extreme: a 1000 pound guy on your lil CL360 will never get to the same top speed as you will being svelte. And you will get to any speed a lot faster than him.

So while you can look into engine specs and dropping a lot of cash into a project to get just the right ride, if you are only looking at "TOP" speed, not how fast you GET there, then gearing can go a long way to that aspect. My '72 CB350 took me quite quickly to 60 mph, not so fast to 90 mph (I lost my nerve shortly after that mark), but at that point it was the rpms being nearly maxxed out, not that there was not enough "push" to get me faster under different gearing.

Not quite true. Weight only affects acceleration, not top speed. Top speed is purely a function of horsepower and coefficient of drag. To go faster you either need more horsepower and/or better aerodynamics.

Yup. To get a higher top speed you first need the gearing to achieve it. After that, you need power and aerodynamics. Both the Honda 350 and 360 have enough power to redline it in top gear though, so gearing is a good first step to higher top speeds.
 
Re: Cl360 "vader"

Great responses, very nice read as well.... so first I think I will change the sprocket. How much can I bore the engine before having to port and oversize valves. I have an extra set of jugs sitting around so I don't have to sacrifice riding time in our peak season. Has anyone stayed with stock valves and cam but gone with larger pistons/cylinders?

Re: Cl360 "vader"

Also, don't worry I am working on a fork brace to fit around my ridiculous yet AWESOME tires.

I think pj's setup is high compression and overbore without too much on top of that.

Yeah, but you have to admit, that a 1,000 pound rider is going to have to push a big-ass hole in the air. ;)
 
Just to point out, it sounds like you went the wrong direction with the sprocket. Bigger front or smaller rear for speed. Smaller front will provide more acceleration.

Not necessarily.
Smaller displacement bikes will usually give you a bit more top speed if you gear them down a little, so that the engine is at peak torque when you reach top speed. Higher gearing does not mean more top speed, it means lower RPM at a given speed. Smaller engines need MORE rpm to achieve maximum output at top speed.
 
Re: Cl360 "vader"

I had a dream last night... No joke that I built a chain shifter for motorcycle like the one on my bicycle. I forgot I had the dream until I read this. I need to get out more

Re: Cl360 "vader"

Tapered exhaust needed a small chop. The way they come stock if you mount them with 1 1/5 inch adapter you will have a leak that hits your legs and is plain ol sloppy.
