Hi, Dan from the uk
« on: October 22, 2020, 07:45:30 AM »
Hi all,  Dan from the uk.
I've owned my 87 Hurricane 750 for 11years now. The first 5 years she was my daily ride and first road bike.
The poor thing has been through every weather condition you can imagen and clocked some hard miles in it's time.

Well after life events like we all have,
Shes been sat in a dark garage for past 6 years. Cant deny we fell out of love for a while.
Well after coming across a 1997 ninja f3 (sorry to use the N word around hear)
last year for a bit of cheap fun, I cant deny that I look at the Hurricane next to it and think for a ten year older bike the Hurricane is an all round better bike.
So for the past few months I've been working away at the Hurricane slowly ticking off service parts and trying not to break more than I'm trying to fix.

I've still a long way to go with her but I'm not in any rush to get her back on the road, but after 6 years I got her started for the first time this weekend. Hurricane is Alive!
Well I say started cylinder 2 isnt firing,
But its enough to get some fresh oil and water round her system and blow out a rusty exhaust aka smoke bomb.
Things are comming along on the Hurricane and I'm sure il be around here alot recently searching information on The Hurricane.

Hi Dan, welcome, I hope you can find the info you're looking for here, we tried to be complete.
Success with rebuilding your bike, do it slow and do it good. Start with the simple things first, put new sparkplugs in and clean the carbs.

 Same, take is slow. Gave mine a full refresh in the 1st lock down. A friend is using it at the moment, but has just go himself one of these ugly twin BMW's, and needs loads of work, so should get it back in the spring.

Yea I'm not in any rush to get it back on the road, my target is next years TT races in May/June.
I've been working on it  steady away.
Gave the carbs a good clean last weekend.
The float bowls were quiet bad and carb 2 had a blocked slow jet.
After several hours cleaning and polishing
Unfortunately cylinder 2 is still not firing. smile1004hmmsz
Next thing I'm going to do is change the spark plug in cylinder 2,
they are all new but one could be faulty.
And I'm going to check the drain screw on card 2, to see if it's getting the same fuel amount as the rest.
The exhaust is going be a problem, the bottom collector is pretty rotten. Think im going to have to pay for somthing decent made.
When I have her running on all four cylinders il then get the front shocks off for the fork seals doing. They have been bad for quiet a while and leaked all over the front wheel.
So yea plenty to be doing.

I dont think I've been on the USA cbrforum.
But I was on here around 2009/2010 which is why you might recognise me. Possibly,

Yea I'm not in no rush with the bike,  il be happier when I figer out the cyclider 2 issue.
Just hope it's not somthing like a piston ring or engine related, that's a little out of my compitace league.

You're right, it was here, I knew the name, to my excuse it was almost exactly 10 years since you were last online here :technik010:
Like i wrote, first try the simple things like spark and fuel, when that still doesn't work a compression test could be useful.
That could make clear if either valves or piston(rings) are the problem. Keep us posted, at least it will keep you busy.....

Had the same problem with mine years ago, with one cylinders not firing. Plugs ect did not make difference. It was a carb problem. Had them out 3 time, and cleaned all and blasted all the air ways through. Must of been something that did not want to shift, put purred like a kitten on the 3rd attempt, and has ever since.

Thanks for the encouragement smile1004yesh
Think I'm going to have to whip the carbs out again. It's the biggest job I've ever done on the Hurricane. I suspect carb 2 ist refilling, so il take out the float bowl pin/jet and have another blow out see if there is anything I've missed.
I'm sure she going to run sweet when I've figered this out.

Well then, you're lucky, these bikes are the easiest to get the carbs out you'll find anywhere.
Loosen the 2 bolts holding the airbox to the frame, loosen the 8 clamps holding the carbs, take the fuelhoses off and the carbs are out!

Cool, so got the carbs out again this afternoon.
Bit of a struggle at first, but i found twisting them up from the back seemed to slide them out well.
I kept the carbs up right and had separate bottles to drain each carb into, to see if any had an irregular amount of fuel in.
Well carb 1 all good, carb 2 zero.
So I went straight to the float jet and found the pin inside seized.
After carefully taking it out I notice alot of green oxidation inside the jet.
After Some quilty carb cleaner and a cotton bud  the pin moves freely now.
Il hold my hands up and say I didn't clean the float jet first time I took the carbs out. #mybad smilywhistle
Simply because I didn't know better. There is a tiny spring that holds the float and it looked so fragile I dearnt touch it. :QW:
Now I know better.
I'm pretty confident this is my issue and going back to the carbs was a good call thanks.

Just need to find the time to get them back in and hopefully hear her purr!!

Well done, sounds like you found the culprit, never be afraid to touch anything, just be smart and take pictures of what you do so you'll know how it should go together again.
You'll find the carbs will go on again easier after lubricating the rubber edges on the head (insulators they are usually called) with some oil.
Keep going, and keep us posted :thumbs:

Before you put the carb's in, it is possible to balance the them. Suck balancing!  Sounds made, but I have had the best running engines by doing this. If you suck ( with your mouth) on #3 carb ( the master carb) , then do the same to #2 and 4 , adjust the carb so the suck resistance is the same, then do #1 carb. I have always got better results this way, over vacuum gauges. Worked in a garage for 14 years, and was a MOT tester, before working for myself, then moved on into engineering.

Where do you suck? Not on the nipples where you would connect the gauges, because that is just an open air connection when the carbs lay on the workbench. Or on the end of the venturi pipe, that normally connects to the cylinderhead? I'd rather not, you'll never get that fuelfree, quite detrimental to your health.
I have been using the same old simple set of vacuüm gauges (home constructed) for the last 40something years, most bikes only need checking every 5 years or so, when there are no changes on intake or exhaust. Only when while checking valve clearances large changes are detected, but then there are more things to be considered as to the cause of that.

Well all went ok,
All cylinders are firing now.
I didn't have her running long as there is smoke comming out the exhaust everwere. I need to get her outside and let her run for a while.
I do need to do a carb balance. I dont think ive got the experience to do it the way you suggest, I might have to see if I can loan a gauge sett from somewere and give it a go. I thought carb 2 was the main carb?
I'm sure il be back asking about how to balance them.
I have seen a thread about it somewere.
But im happy now all 4 are firing smile1004egypt

My next challenge are the fork seals. Think I'm going to take out the forks and take them to a local bike shop to be done. I'm not 100% confident in replacing them my self.
Will be glad to get them replaced, its one of the reasons the bike got shelved many year ago.

My exhaust is a large issue at the minute, the bottom collector is a bit of a rusted mess and the manifold seems to let alot of smoke out  smile1004170
I'd like to find somewere to make a new  stainless steel one, I know it will cost alot but I think it's worth it In the long run.
