CDI Purchase

[zombie]

I've learned to read the customers... On Friday afternoon I got a call from a referred fella that broke a trailer wheel bearing. I got him to the shop, and he also wanted a bottom paint job... I quoted /he left. He called 2 hours later to ask if I would go back to the shop (7:30 Fri) so he and his wife could take some picts. of the boat "in case you damage anything". I said "Sure Thing".
When they arrived his boat was waiting on the edge of my property for him to take it home.

Maybe he should have visited the forum first...

I have a feeling that the wife was the one who raised hell about taking pictures when he got home 

Last job I did, Wednesday, the guy told his wife the lift had some mud on the base because I was kicking it to align it properly(solid steel that will hurt my foot long before it hurts the lift). He tells me she said, "you paid all that money and he's kicking it!" The guy tells me, "well I told her I kicked it once too"  . He was cool but a little bit of a pain in the ass. This guy insisted we didn't get mud on his concrete after it rained the night before. His building was new construction and surrounded by mud. Well how the hell am I supposed to back the truck in or carry tools in without getting mud on the concrete? Just have to suck it up sometimes

I think the investment to put a BBK on is worth the money.  However, I am not sure affording all the other items is within the budget.  If I can go 45 with OEM, that is good enough for me.  I will look into a kit, but I am not sure how to tune a carb very well, so I am stuck with having someone tune it for me.  I will talk to my scooter guy back in ST. Louis as I am going down there in July.  He tried talking me into one a year ago as I had to decide between new tires or a BBK.  Went with tires, should of went with BBK at this point.  I might be emailing about the cylinder.  Is anyone on this forum in Nebraska?

I can not seem to upload the piston/cylinder pics.  If zombie you have an email, I can send them to you.  The piston has major vertical chunks out of it.  The cylinder wall does not though.  What normally goes wrong in situations like this?  It is a 2001 with 4500 miles on it.  I think just a rebuild is the way I can afford to go.  I want to get a BBK, but the other items that need to be changed would be out of a budget for now.  I want to get ahold of that cylinder if I can for 20 bucks.  What is the best way to go about this?  Paypal?  Thanks again.

Understandable

"What normally goes wrong in situations like this?"
Hard to say. 4500 miles is not a lot. I would definitely inspect the carburetor and lubrication systems thoroughly.

[ohface70]

What should I be looking for in the carb and the oil pump?  I know the oil pump works as I have to put the 2stroke oil in when I fill up. 

[Peters]

Damage comes within minutes of no lubrication.

Here's a link to the manual

I just downloaded it myself. Save it to your computer. I've used the one for my People countless times. It's a very valuable resource.

With the carb, mostly just give it a good cleaning. A can a carb/choke cleaner works great. Remove all the jets then put the straw on the can and blow out all the ports and passages.

Post some pics of your piston and cylinder. Zombie reads pistons. He may be able to shed some light on what caused the failure.

Is that the bike in the bottom Pict? It already has a pipe on it. 1/2 the cost of a bbk is right there. Anyway... The piston did destroy the cylinder. Is the TOP of the piston burnt or pitted? If it is JUST the sides below the rings it is an Oil failure, or a newly developed air leak. An Extreme leak at that. Cheap walmart 2toil is notorious for failing in scoots same with hardware store chainsaw oil. First thing is to get out any suspect oil, and buy a good injector oil, at a Bike shop. Second... I would suggest doing a pressure test after installing a cylinder. There is a bit of work to doing this but it really has to be done so that you do not destroy all your work in a few miles.

. I have a good jug, and gasket set. I' will sell the gasket set for 5 bucks (what I paid), and the jug for 20. Where are you? Nebraska? It might cost 10 bucks to ship it. I'll find out today. I'll post back after work, and we can PM details. I can send you the parts, and you can payapl after you get them. It's all good.

Looks like lubrication issue.  1 year ago I was stuck in a hail/rain storm.  Water was over the edge of where your feet go.  I can assure you this has to be when it happened cause it has never ran right since that day.  I though it was just the ignition coil (it was broken from corrosion) but looks like it was from the rain.  And man was that a rain.  My neck looked like I had about 20 hickies on it from the hail.  Piston with lubrication failure.  I use motul (spell check) 2 stroke oil.  Is this a good oil? 

Zombie, lets chat.  It seems you can assist me quite abit.  Yes, that is a picture of the scooter.  I put that exhaust and the tires on 50 miles ago.  Can you talk me through or send me a link for a BBK if it is within my budget.  I am gone tonight, but I will check this when I get back.

Is this the kit you were speaking of?

[zombie]

That's the kit. Sounds like you're on the right track.
