Awesome Speed & Shut Off

There is a much better/easier way to clean the carbon out than taking it apart and cleaning with kerosene.

Run it around till its good and hot. Buy a can of seafoam and a syringe, remove the air screw form the carb and with somebody holding the bike wide open begin injecting the seafoam, get a good half a cup in there going slow enough to keep it running and then start injecting faster till it dies. let the motor sit for 20 minutes, replace the air screw and fire it up, will smoke out a city block but it will clean out all the gunk on your piston and head.

I got seafoam and a syringe. i just need to take off the body panels.

but wait, should it be idling while i inject stuff in and what do you mean by wide open? WOT right? hmm.

Yea hold it wide open so it stays running.

All rightie. I'm about to commence.

so how soon will i see improvements cause right now, after 30 minutes of waiting around, it only went 23mph, 25mph downhill.

It did shoot out tons of smoke though

So I have no improvement and it hit 35mph yesterday and then quit out on me but once it dropped down to 15mph, I was lucky enough to get it back to working.

You carb is clogged.

Your engine is slowly self-destructing from all the soft siezes. It will continue to get slower and slower, with occasional runs up to higher speeds and soft seizures, until one day when it either won't start, or hard seizes the piston.

Don't believe me? Pull off the head and take a look at your bore, I'd bet you it's already scored up.

Kenny: The problem is not electrical or due to the idle jet. He is leaning out the engine over and over again.

how can i fix it then? it seems like everything else is in working order.

if it does seize, what engine should i swap in?

Look at your main jet size and post back. It's written on the jet itself.

First, though, run a compression check on your engine. If it's below 100 PSI, pull the head and take a look inside to assess the situation.

Do you have an air filter on it?

I'm pretty sure I do although my friend, who I bought it from, helped me do some restoration work on it and he told me that he had already cleaned it and that it was a b**** to oil.

Anybody live in the south bay in CA? Maybe they could take a look at this because I just can't figure out what's wrong. Just got a new petcock but don't know if it's the correct sizing.

I am going to rebuild the engine this weekend. Any guides on how to do it and anything I should replace when I take it apart?

Did you say this is the 7th time that you have cleaned your carb in 3 months?if it is your not doing it right...just pull off the cylinder and check for carbon..because this happends a lot...there's usually a lot of carbon build up...
