Clicking/ticking sound (Pics & Video) 87 Spree (FIXED)!

[indetrucks]

here ya go

You rock, thank you for taking the time to do this for me.
I really appreciate the extra effort

I'm going to order some parts and post my progress/pics along the way.
Hopefully I can get the scoot goin by mid next month as that's when my next race is.

Pit bikes are almost as fun as race bikes

So finally got around to do the compression test and its at 120.
Did the test twice and it maxed out the same both times at 120.

I buttoned the scoot back up and ran it with the new belt and new clutch shoes.
It seems to do about 28 now with limited room on my street. Might do 30 with some space.

It still accelerates like a dog and almost feels worse than before the new shoes and belt were one. hmmm
I didn't get a chance to put a new clutch bell on, so I just used my old one. The old one had lots of blueing and measured just at the min. thickness requirements.

So two issues:
1)That clicking sound is in fact still there and the bike has lots of compression. I don't hear it at speed, only at low idle. Hard to say where it's coming from but mostly around the jug/oil pump area.

2)Other than using my feet to get me going, think a new(er) clutch bell might help the acceleration?

[Trafficjamz]

I don't think a new clutch bell will do any better.......but I sent you one today any way.

lol.. yeah I just saw that.
You didn't have to refund me man, I understand. I figured It would be easy enough to put yours on there when it "eventually" showed up

Any ideas on that clicking sound? hmm
Maybe I should pull the oil pump and start it for a few seconds to see if the noise went away. (only a few seconds)

If you add some oil to the gas tank you can remove the pump to test.

You can't run it without the case sealed up though. Just pull the pump gear to test

[indetrucks]

Ok, good call...
I'll pull the pump, remove the gear and reinstall.

Will report back

[indetrucks]

Removed the oil pump, took off the gear and reinstalled.
Noise still present.
So I said screw it and went after that top end

After pulling the head I could actually move the piston within the cylinder with my pinky finger. The rings were still in tact and I am fairly certain this was the stock piston (2,000 + miles).
All the nuts and bolts were untouched and by the looks of it, this was the OG piston and cylinder (you guys would know better than I)

Here's some pic for your viewing pleasure (I know how we LOOOOOOVE pics)

[indetrucks]

As you can see, the piston was slapping around pretty good in there. The exhaust side has nice grooves and I'm fairly certain that if it was to be ridden like this any longer, $hit woulda went downhill quick.

More pics since ya only get 3 per post.

[indetrucks]

What's really crazy is the compression still being at 120 prior to the new piston (haven't checked with the new install yet).
But the bike would still hit 28/30 mph, even with that crazy piston slap.

Take a look at the carbon build up on the head...

I did a real nice cleaning of it with the old Dremel and polishing wheel.
Check the latest video and do a before and after with the first video... NIGHT AND DAY

I will add that even after a new piston and cylinder, the spree accelerated SUPER slow and takes FOREVER to get up to 28MPH. (Hoping it does 30 with more road).
The bike run essentially the same as before but without the piston slap noise. Any ideas?
Looking at the pics, I almost want to say that scoring was caused by oil starvation. Does this look like the case to you pro's?

I come from bikes (bigger ones) so maybe I'm just not used to this little scoot? But to be honest, I would NOT feel safe driving this on any CA roads. (maybe my alley or as a pit bike at the race track).

I think my main concern over top speed is the acceleration. I have the carb screw turned out according to the manual 1 3/8 from in. I have also tries 2 turns out and 1.5 turns out. Both times running up and down the block didn't seem to make a whole lot of difference. Only thing that went up slightly is the idle.

IT'S A SPREE! dude lol just be lucky you have the model that does 30 there is only three ways to go from here, 1, spend money 2, spend more money 3, sell the bike! good luck to you!

[indetrucks]

lol, I hear ya... I'm ok with the top speed, it's the "getting there" I wasn't sure of being normal or not.

[Mystic]

ahahah yea at stoplights and stops at an incline you have to give it a good fred flinstone to get rolling

[indetrucks]

ok cool... as long as it's normal, I'm good with it.

Scoots really fun to tinker on though, love figuring things out
